Samsung Smart Bike MCUs For Your Bike

Bikes present a wide range of opportunities to use microcontrollers to improve your riding or at least give you a new experience. This posts briefly looks at a few of those opportunities.

Samsung Smart Bike

Tonights collection of bike related MCU projects and ideas was prompted by reading "Samsung Smart Bike packs an Arduino and frickin’ laser beams," a June 12 post in Geek.com. Geeks post said:

"Samsung’s been working on a concept bike in conjunction with Maestros Academy...For the smart bike in particular, the design team wanted to help reduce the number of cyclists involved in accidents each year...Front and center (literally) on the bike is a magnetic smartphone mount. Slap on your Galaxy phone and fire up the app to control the bike’s systems. There’s onboard LED lighting for nighttime riding and a rearview camera so you can safely keep tabs on traffic as it approaches from behind — video is streamed to your bike-mounted phone. And then there’s the four bike-mounted lasers. The lasers on Samsung’s bike aren’t designed to take out incoming foes...They’re part of the bike’s safety system. Fire them up, and a virtual bike lane gets projected onto the roadway to make sure motorists give you enough room to

ride...How does the bike communicate with your phone? It’s hiding the maker’s secret weapon, an Arduino, which gets paired via Bluetooth. The Samsung app also

Laser bike lane concept

does the typical social fitness stuff. You can track your rides and share them with other smart bike users, see where other people are riding, and even keep tabs on how many people are riding the same path as you in real time."

The Samsung Smart Bike is just one type of MCU-bike project. Using MCUs on bikes can be divided into five categories:

1. MCUs improving biking experience but not connected to the bike
2. Bike-connected MCUs for independent projects
3. MCUs integrating multiple biking features
4. MCUs connected to bike and to smartphone
5. MCU-controlled e-bikes

Numerous MCU posts could be written about each of the above categories of bike-mcu combos. For tonights post well just briefly descibe each category and mention related projects or webpage links.

Flora brake light backpack

The first category, bike-related MCUs which arent bike-connected, covers items like this Arduino blinking bike patch backpack, this Flora brake light backpack or this jacket which uses an Arduino to light up an arrow or other rider-visibility features. The MCU in these projects arent actually connected to the bike or integrated into its functioning, but they do create a better riding experience.

The second category, bike-connected MCUs for independent projects covers items like the bike speedometer from Instructables or some of the Arduino-bike projects from the Intro to

Bike speedometer

Arduino Pimp My Bike series. To find a specific bike-mcu project youre interested in, just Google for  bike Arduino [or microcontroller] xxxxx, where xxxxx is the topic or type of bike feature or function in which you are interested.

MCUs integrating multiple biking features includes projects like this bike dashboard Instructables which integrates a lighting system and a speedometer. An Arduino or other MCU system can control a wide variety of sensors and outputs, so you could include front and back-illuminating LEDs or lasers, blinking LEDs for turn indication, photosensors to automatically turn on your bike lights and lots of other physical computing features that are functional, cool or both.

Bike dashboard

The fourth category, MCUs connected to the bike and a smartphone have a huge upside for innovation and benefit in the next five to ten years as smartphones add sensors and computing power and as MCUs continue to become more powerful. This category includes projects like the Samsung Smart Bike. The MCU controls and communicates with a wide variety of devices and sensors, and the smartphone can easily connect your bike with the internet and with your friends or other bikers.

MCU-controlled e-bikes represents the largest financial impact of MCUs on biking to-date. China has been a huge market for e-bikes because of the size of the population, the low cost transportation provided by e-bikes and the effort to reduce or minimize pollution caused by gas or diesel vehicle engines. Here are two e-bike overview PDFs; a Samsung application note "Electric Bike Controller System" and a Texas Instruments application report "Hardware Design Considerations for an Electric Bicycle Using a BLDC Motor."

What type of MCU-bike project would you like to work on with the Humboldt Microcontrollers Group? Come to the next meeting, tomorrow night, Thursday, August 21, at 1385 8th Street, Arcata, California, and discuss that project with the MCU group.

dear everyone

This is about people...most of you in fact. You know who you are. I mean Im so serious about people reading this its even going on Myspace...

Its about people and other peoples boyfriends. Lets start with subject one.

So people dont really like her boyfriend...yeah we got it. I know you all think she deserves better...but ok its GREAT to say that she deserves better. I mean no harm there. HOWEVER suggesting that she leaves her boyfriend and even encouraging it is rediculous. She has heard our suggestions...now she can decide for herself. She is a big girl.

Ok and subject two.

People dont like her boyfriend either because...well a number of reasons...like he changed her or all of a sudden she has gone mega religious.

Well ok

Here is what KILLS me about you guys.

You say "how can you trust and love someone so much when you dont even really know them?" Thats basically what you say right? I mean the pics are old and it could totally be some old dude effing around right?

So far everyone who says this believes in God...someone you dont know and there is no real proof of his existence except some other dude told you and wrote a book on him...

sounds a little contradictory to me....

Not saying she is right or that you guys are wrong...I just think its an INCREDIBLY stupid reason to leave people behind. I mean what if this is all just bullshit? The last thing someone needs is to hurt all by themselves. If anything everyone should be giving her MORE support even if you do think it is bullshit.

Now Im not trying to preach to anyone...just saying. I mean Im pretty vocal about not believing in God yet none of you rub it in my face? Why are you smearing their faces in your beliefs?

SOMEONE PLEASE HELP ME UNDERSTAND!!!!

Keeping your Records up to Date

I think Im going to have to wait until the new year to turn over a new leaf about keeping records. I think I have set-up and started a record keeping system about seven times now and every time I have a problem the records go out the window until I can finally come to gripes with the cause of the problem. This mostly occurs when I have a fish kill. I hate losing even one of them and I struggle with myself and tend to blame myself until I or someone comes up with an acceptable answer.

The fact that fish kills can be expected at any time and with no apparent reason doesnt change the way I feel.

So if you happen to have one or two floaters, and you get to feel a bit guilty about it.... YOURE NOT ALONE.....

Anyhow back to fishin and planting...

Clarendons Rural Agricultural Development Authoritys (RADA) extension officer, Orlando Rowe, was on hand to demonstrate such a method to patrons inside the Clarendon parish showcase at the 58th annual Denbigh Agri-Industrial Show....

There is money available..... Programs that work to research the development of aquaponics and...

 Now about those floaters....

Now a Lady and her favorite pastime....

Now some BSF News
I learned that these larvae emit a chemical signal that keeps houseflies away. Sweet. And chickens love to eat them.

And heres more on BSFs

And Finally....

See you Soon

Daemons Car duino Tracker

Daemon by Daniel Suarez is an excellent book for most people who are interested in microcontrollers (MCUs), and Im currently in the middle of re-reading it. The MCU project in todays post, OpenTracker v2, is something that would have been right at home in Daemon.

OpenTracker (well drop the v2 suffix for the rest of this post) is an Arduino-based GPS / GLONASS vehicle tracker. The August 21 article in Electronics Weekly gives an overview of OpenTracker and mentions a couple use cases.

"This one could of interest to a Gadget Master looking to track moving objects, such as a vehicle. Want to monitor your elderly parent, perhaps, or keep an eye on your son or daughter’s first driving adventures...The people behind it, Tigal, are raising funds on the Indiegogo crowd-funding website...it’s actually the second version of the firm’s open source GPS/GLONASS vehicle tracking system...As well as tracking single or multiple vehicles, it also monitors the speed and altitude of the objects...The Arduino Due compatible module has an Atmel SAM3A8C ARM controller, a Quectel M95 GSM/GPRS modem and a Quectel L76 GPS/GLONASS module..."

OpenTracker v1

TIGAL just completed their Indiegogo effort to fund the development and launch of the second version of this moving object tracking device. Their Indiegogo campaign raised only €3,319 toward their funding goal of €50,000, so the new version of OpenTracker didnt get quick or strong uptake in the maker community or the general public. Because the Indiegogo effort was a flexible funding project, TIGAL, the developer of OpenTracker, keeps the money pledged. Also, TIGAL is an established Austrian company that sells the first version of OpenTracker online, as well as other products. The first version can be found online for €118.80 including 20% VAT.

Based on the online description of their company, TIGAL will likely continue development of the trackers second version in spite of not reaching their crowdfunding goal. It will likely take longer for the second version to become available, so if youre interested in this open source  moving object tracker, you should probably just buy the first version to learn on while waiting for the second one to appear. If you do interesting hacks with v1, TIGAL might want to have you be a beta tester for v2. Their website describes the company this way:

"TIGAL is a...international distributor and manufacturer of...innovative technological products.  TIGAL’s product line includes embedded Linux/Windows CE devices, M2M solutions, wireless devices, CAE/CAD, development systems and compilers, professional programmers, measurement tools, LCD and OLED displays and display modules with and without touch screen functionality, and speech recognition development tools and systems. TIGAL is also leading several OEM projects with its international partners...in the fields of SMS and MMS messaging, Voice Recognition and Linux-based development tools and embedded hardware."

If youre considering buying or building a GPS tracker, you might also want to look at a few of the

other open source trackers. I didnt do in-depth research to find out which have the best reputation, but here are a few links to get you started:

GeogramONE board

1. GeogramONE (originally released as DSS Open Source Tracking Device on Kickstarter) -- $120.00 -- "The Geogram ONE is an open source tracking device based off the Arduino platform.  After a successful Kickstarter campaign, several hiccups in the manufacturing and assembly process, were proud to announce the Geogram ONE is finally available for sale. Were selling the bare bones board here for development, however to take full advantage of its capabilites youll still need...accessories...The board also comes preloaded with firmware to use as a tracking device.  Communication is handled simply by send an SMS from your smart phone."
2. RuuviTracker -- "...an open-source, electronic global positioning device as well as free

   

   RuuviTracker Rev C PCBs

   software. Our GSM- and GPS/GLONASS/Galileo-enabled tracking system can be used for various different tasks...it can be used to track your hunting dog, it can become your vehicles alarm system, a portable weather station, a security system for your children...The device itself will be an affordable, water-proof, robust, high-quality and state-of-the-art product...We have, for example: 168MHz ARM Cortex-M4, GSM, GPS, GLONASS, Galileo, accelerometer, microSD, microphone, speaker etc. The device draws only few microamps during sleep, so even a small battery might last for several years. Additionally, our accelerometer is able to wake-up the device when its touched." Heres a link to the project status page on their wiki. They appear to have completed a Rev C PCB (printed circuit board) for their tracker in June 2014. 
3. GPS Cookie (funded with a Kickstarter project in 2013) -- $89.00 -- Overview from

   

   GPS Cookie

   CNET: "The GPS Cookie runs on two AAA batteries and records data onto a microSD card you supply. It records data, time, and location to track your routes, letting you build up a history of your movements. That data can then be imported into Google Earth so you can visualize your travels. The idea behind the gadget is that you just carry it around and not worry about it until you upload the data to Google Earth and see your information. This could come in handy for travel abroad so youll be able to locate that out-of-the-way Parisian cafe later. It can also be used to track bike routes, commutes, or just about any travel adventure."
4. Adafruit Ultimate GPS on the Raspberry Pi -- From Martin OHanlons blog post about this Adafruit GPS tracker: "I got myself one of adafruits ultimate GPS breakout boards as I want to experiment with capturing GPS data in my car projects.  Its a seriously good bit of

   

   Adafruit Ultimate GPS on Raspberry Pi

   kit and if you looking for a GPS module you could do a lot worse than this.  They also have an excellent tutorial on setting it up with the raspberry pi...I used the raspberry pis on board UART to connect to the GPS module, Adafruit advocate using a USB to serial device but that didnt suit my needs (I need the USB for other things). I also create a GPSController class in python to allow me to communicate with the module easily."

Ive never done a maker project with GPS tracking, but it appears there are a number of options for doing that with open source designs. If you want to track your child, your parent or a potentially wayward or nefarious client (I have no idea as to the legalities of any of those activities and IANAL) or if you want to clearly understand how someone might be tracking you, this post should at least point you in the right direction...

Uri Oliver Vaughn

Seriously I had nothing better to call this blog so I gave it an actual name. I just Googled cool names and randomly picked three.

Anyway, this blog is about yesterday and this morning up until now.

So yesterday was the hardest day ever...in a long time. I had trouble getting out of bed. Just didnt really have a drive. I havent been very me-ish lately...so I hope everyone forgives me for that.

I tried to make coffee but the coffee maker had odd smoke coming out of it. OK well I was warming up old coffee from like last week to use in conditioner (which adds shine) but my coffee maker looked like it was going to blow up.

Four hours after I attempted to get out of bed, I finally got to my bus stop to go to school where I was going to finally finish my English work due. Some lady asked for the time so I told her. Big whoop right? Well then she decided to tell me her life story. Her name is Teresa and shes an alcoholic. She went to jail for drinking and just got out on parole but started drinking again.

So Im stuck talking to an alcoholic till my next bus comes. FML?

I made the mistake of telling her how I understand that getting into rehab is hard (after all I know someone that tried but didnt get in till she ended up in the hospital) and then Teresa went on and on and on blabbling drunken words...when finally my bus came. WIN

What got to me is it took her to relapse before she saw she needed help. For those of you that didnt know where my original screen name (sober drunkenness but spelled differently) came from, its from that. It was originally drunken sober but apparently at the time someone had that ID on Yahoo. Anyway it came from people like Teresa. People that become intoxicated but finally figure out what they need to do all along. Its almost like theyre blinded while sober and fail to see things how they are but see what a mess they have become once they are intoxicated again (which usually helps them stop) and thus, having drank themselves sober.

so now ya know.

Anyway while on the bus, Thim calls and says we besta hit up the library for some junk.

Just as a not-so-side note, I figured out our problem.

So we were on our way to Arcade library (which I thought was Del Paso) to drop off books. That was cleared up and I now know that one as Arcade (or Arden Arcade) library.

Now Thim called Hagginwood, Del Paso, but is for sure not Del Paso. Hagginwood (also known as North Sacramento) is on Del Paso Ave but Del Paso library is on Grand Ave. Its the whole Sacramento being theoretically correct.

ANYWAYS

Thim, Alyssa, and I went to Hagginwood library (on Del Paso Ave) to go to an anti valentines day party (or something like that) lol. It wasnt big. It pretty much consisted of me, Thim, Alyssa, a gal that worked there, and a guy named Daniel. We played brawl and did Bingo where everyone won but Alyssa which was lame on her part. Then we had a piñata that was shaped like a heart. I was oldest so I struck first...however I hit it hard enough to destroy it in one hit. LAME.

Then I went home where I ate a crap load of junk food. Man I really need to cut back. But, I was hungry and it was the first thing I saw unfortunately.

And so now it brings us to Friday (today yay I guess maybe) and me being at grandmas. Well I was sleepy and wanted a blanket but when I went to open the door, the knob just kept turning. WTF I was locked in!!! I tried a number of things. Finally I found an old safety pin which had a mickey mouse head (most of the ink used to create the head rubbed off from it being from the 90s...yup) and opened it up to help prop the door opened

FREEDOM

but now Im not even tired anymore...how lame.

And my newest addition which JUST happened, the discovery of the most ironic computer name since windows.

Freedom.

From the website, Freedom is an application that disables networking on an Apple computer for up to eight hours at a time. Freedom will free you from the distractions of the internet, allowing you time to code, write, or create.

...what...

as far as the windows bit...I meant their whole saying "windows, life without walls" but how can you have windows without walls? I mean without walls you just have glass.

please enjoy the party while your music is being reached

So today...fail day II

Thim went to pick me up from Adams house...and FAILED like WTF.
dsf7jnybgfre4tyhjmukjnhb6g5vcf4

XD

So we were riding to school with ging-ah, yacob, and thim driving...and the radio was talking about this dude. When they called him back it said "please enjoy the music while your party is being reached" and the first thing I did was sing "GIVE INTO THE NIIIGHT"

thats adams callback tone. I call him too much XD

then while I was trying to explain it to people I said "please enjoy the party while your music is being reached"

lol

And Im totally wearing adams pants and socks cause mine are soaked.

and its 8:05 AM...so were not even done failing today.

Make Your Arduino Go Fast A Modern Go kart

Electric Arduino Go-kart (from Instructables)

As the Hackaday post "Electric Go-Cart Has Arduino Brains" says, most modern vehicles have lots of their functions controlled by computers (or microcontrollers / MCUs). The 2014 go-kart thats the subject of this post is truly a modern vehicle in that respect.

And...the go-kart will make your Arduino go pretty fast. In MPH, not GHz.

I first saw this go-kart mentioned on Google News in the Unocero article "Un Go-Cart eléctrico que usa Arduino," so if your native language is Spanish, you may want to read that version of this tech story. Google News is nice that way, because sometimes I see a non-English article that lets me know about a story Id not have read if it wasnt in English. Google Translate certainly is not perfect or even almost perfect, but it usually gives a usable version of the article, and you can do more Googling based on the Skynet-translated version of a non-native language article.

Steering wheel showing LCD screen (from Instructables)

It appears the source of the story about this Kartduino is the "Electric Arduino Go-kart" Instructable done by a 15-year old from California. The Instructables write-up presents some of the technology used to build the go-kart, but it cautions the reader that its not a complete guide to building the vehicle. Heres a taste of the write-up:

"The drive setup uses a Hobbywing Xerun 150A brushless electronic speed controller to control a Savox BSM5065 450Kv motor. Batteries are 3x zippy lithium polymer - 5 cells, 5000mah. The motor has two large fans I pulled out of an old computer for cooling, mounted right over the motor. The chain drive is a 1:10 overall ratio, using a 15 tooth on the motor chained to a 30 tooth on the jackshaft, and a 9 tooth from the jackshaft to a 45 tooth on the wheel. The tires are 10" diameter so at 20 volts the top speed is around 30 mph. The ESC is controlled via PWM from the arduino. A throttle potentiometer on the steering wheel controls this. Constant current is around 40-50A, and the batteries last around 30 minutes with an average speed of 10-15mph. It requires a small push to get started (really, the motor just has to be rotating) and accelerates extremely fast...This uses a sensorless brushless motor. They are not capable of starting under load. It may need a quick push before it can start. Dont try to start them under load. I already had one motor burn out because it stalled and the current burnt the coils insulation. Sensored motors overcome this problem."

Im sure if the Humboldt Microcontrollers Group ever wanted to build a similar kartduino, Ed and others in the group would have plenty of ideas and knowledge on how to improve the design, with sensored motors or an alternate solution to the sensorless brushless motors that burned out on the design shown in the Instructables.

Go-karts wooden electronics control box (from Instructables)

With regards to the MCU in this zippy little go-kart, the Hackaday post covers the different parts of the vehicle integrated with the Arduino.

"In addition to the throttle control, the Arduino is also responsible for other operational aspects of the vehicle. There are a bunch of LED lights that serve as headlights, tail lights, turn signals, brake lights and even one for a backup light. You may be wondering why an Arduino should be used to control something as simple as brake or headlights. [InverseCube] has programmed in some logic in the code that keeps the break lights on if the ESC brake function is enabled, if the throttle is below neutral or if the ESC enable switch is off. The headlights have 3 brightnesses, all controlled via PWM signal provided by the microcontroller. There is also an LCD display mounted to the center of the steering wheel. This too is controlled by the Arduino and displays the throttle value, status of the lights and the voltage of the battery."

An interesting alternative kartduino I ran across whilst doing research for this post is the

LOLrioKart (by MIT student)

LOLrioKart (see picture at left). This slightly-strange vehicle was created from a shopping cart by a Massachusetts Institute of Technology student. Might be handy for going on a quick trip to Wildberries or the Co-op for groceries.

Speaking of modern vehicles and the increasingly important roles played by MCUs in vehicles, maybe Ford, another vehicle manufacturer, a microcontroller manufacturer or an electronics distributor will in the future want to sponsor a Humboldt Microcontrollers Group project to design and build a modified version of Steve Salzmans vehicle, with upgrades that allow it to parallel park itself as well as generate and track all sorts of vehicle operation data. That will be a fun project!

you know someones new when

Dont you hate it when a book or something youre reading starts with something then they cut to something else without finishing the sentence?  

=]

Anyway so I got at my stop at 6:40 today to catch bus one that comes around at 6:50.  Why?  Because theres this really retarded Christian girl who talks to me and is usually on the 7:05.  I dont hate her...she hasnt done anything wrong to me or has physically hurt anyone (although she does make a lot of fat jokes toward this other girl who I think is retarded...but a little less).  Both think its their way or no way (sorry no highway)...youre stupid and its wrong...its just the bigger one doesnt live it and preach it to the entire planet...nor does she take the bus.  Besides were friends likely due to familiarity...we go back to 2nd grade.

7:15...class in 15 minutes.  Nobody is here.  Why am I the only one who took early classes on Tuesday and Thursday?  FML.  Im the only one that took late classes too huh?  I wish people were here.  I have the table that everyone likes by the tree =]

Oh yeah and what I was originally talking about.  You know you have a bus driver thats new when he doesnt quite know the route.  Bus 1 (like 93 and a few other buses) has some shitty stops.  Im referring to the Myrtle stop going McClellan bound.  Yeah its hidden under some trees and cars parked around it.  I was sitting down and went flying forward.  Prior to that, we were going down Auburn and we totally almost missed the turn at College Oak...as in we were all the way in the right lane and he just kinda moved over at the last minute...blocking traffic (good thing their light stayed red to go straight).  I feel really bad for this guy...they should at least give new people a map or GPS.

So Im thinking Im allergic to Herbal Essence hair stuff.  I used it for about a week (not even fully) and now I have burns on my scalp and neck.  It could be that or this gel I havent used since I was little...but Im doubting it was the gel since I dont recall having burns from it...or even a mix of the two.  Either way Im going gel free for a while till my head recovers.

how to brush comb your hair

because apparently people dont know how.

So basically I have been watching this girl from 15 feet away brush her hair furiously!

Honestly brushing it fast and rough makes split ends and tangles come even faster...and more furious.

so for you people with straight hair or curly hair that youd rather not properly take care of...here is how to brush your hair

step 1
pick up your brush

step 2
grab some hair

step 3
brush it from the bottom and work your way up

step 4
slowly detangle knots from the bottom

TIP
never brush wet hair as it will snag and could break.


see was that hard?

now for curlies

step 1
wet hair thoroughly (shower works best)

step 2
grab some hair

step 3
use a wide tooth comb to comb from the bottom up.

step 4
detangle from the bottom

tip
always comb wet hair. NEVER brush dry curly hair.

Tada

btw most hair doesnt need to be shampooed. Curlies only need to conditioned. Oily scalps can skip the conditioner and use only shampoo. Trust me on this

More Sites to Investigate and Invest Your Thoughts in

One of the absolute attractions of the internet is its ability to encourage our hunger for knowledge. It is the ultimate source. When Bill Gates was asked what the internet was for, He described its content as "STUFF". Really that pretty much sums it up. All sorts of stuff about everything.

Well heres some more STUFF.....
