Around one year ago I ordered some of those supposedly wonderful TI eZ430 “Hackable” Watches but only received them last October since I had to wait for the 433Mhz version. Three months later I finally decided to have a go at trying it out and wrote a Python library for in the process.
The ‘quick and nasty’ software files are still the same as in the previous post. Pure software test only, couldn’t resist the temptation to try it via WiFi on a stock Chumby instead of USB tethering. As such the hardware frame is a bit too flimsy and the batteries aren’t enough to power the Chumby without brown-out resets. These will be improved upon soon 🙂
Mecanum wheel rover/robot base for around $25! Or around $110 with a 454Mhz Linux Processor with touch screen and wifi (Add Chumby + Servo controller). Read on for build instructions. Continue reading “Mecanum Wheel Base”
I didn’t want to fiddle around with getting power to the Chumby, so the test is simply using my trusty old laptop and the EasySync adapter. Only the speedometer, the tachometer and the accelerator pedal position is attached because again I’m too lazy to fiddle with my cable layout and as such its connected to the Mazda HS-Can bus only rather than the MS-Can where the goodie trip computer information is contained.
Almost every concoction of technology is used ranging from CAN, USB, PHP, HTTP, Shared Memory, XML, Flash, to an obscure programming language called HaXe. Here is the result :-
The toys just keep coming in! Another one of those wallet killing impulsive orders whilst I was sick in bed last week just arrived today, a USB-CAN bus converter module by EasySync that promises a great interface and should work in Linux! This will give a little bump start to my Mazda CAN Bus / mChumby projects.
Note : EasySync UK’s online form doesn’t allow international shipping but a short E-mail or two managed that. There is a US subsidiary with US and international shipping, but the international shipping rates on the US site is plain ridiculous [$68USD to ship a $88 device to Australia].
Note 2 : I hear the interface is mimicking the Lawicel CAN-USB interface…only hearsay…
Plugged it in – didn’t work. Doh! Took a peek at the manual and website, nothing on Linux other than “Linux drivers provided”… So much for the marketing material, guess I have to try make it work myself. (Yes I got it working, read on for the quick run-down post aimed at helping others)
This is one of those posts where the sole purpose is for me to upload a few photos for a forum 🙂
I was shopping the other day and came across these cut tin can lolly containers in the shape of a fridge…”That’ll be a great Chumby shell! All I’ll need to do is make a cutout at the front and a couple of holes at the back!”
Just thought I’ll do a quick test tonight with a chisel and a hammer… wasn’t too bad but I did it in a rush so there was an uncoordinated side cut…need to file it a bit…
The idea is to put a USB hard-drive in the ‘fridge’ as well and voila home media/web server 🙂
