Reed-Solomon Error Correction Encoder/Decoder for Embedded Devices

Reed-Solomon Error Correction Encoder/Decoder for Embedded Devices

This is a port and modification of Minsky’s Reed-Solomon Encoder/Decoder RSCODE module (found at http://rscode.sourceforge.net/ ) targeted for 8-bit embedded devices. RSCODE supports a variable message size up to 255 bytes, fixed at 8-bit symbols, and the ability to correct erasures as well as byte errors. RSCODE is licensed under the GPL for non-commercial use.

To support embedded devices this C …..

Arduino based Large Digital Clock with 7 segment display

Arduino based Large Digital Clock with 7 segment display

I’ve been working on a prototype for a large clock I want to make.  This clock will feature 6.5inch digits for the Hours, Minutes & Seconds and will feature 4inch tall displays for the Month & Day readout.  Being as I am going to hang this clock up at work, It will likely be high up on the wall and …..

[Project Log] Custom motorized bicycle Pt.4

[Project Log] Custom motorized bicycle Pt.4

I noticed that i’ve started my last three post with the word “well”. I think i’m a guy of habits.
Finally after a lot of thinking I bought a 1980′s Sturmey Archer AW 3 speed.
I spent a lot of time cleaning and overhauling it. I even had to make a tool to unscrew a fu**ing cap. It was WAY too stuck. …..

Flex Sensors by Flexpoint

Flex Sensors by Flexpoint

I have just been playing around with some sensors by Flexpoint. And I have to say, that I really love them…

While the company appears to focus on custom design, they produce standard sensors in three sizes, 3″, 2″ and 1″. The actual variable resistor within the sensor is a bit shorter. Check the image for approximate actual measures:

Other flex sensors …..

[Project Log] Custom motorized bicycle Pt.3

Well, it’s been a while since my last post, but i’d some troubles.

I went to the bicycle shop to pick up the nexus 7 hub, but the guy said that he tested it and it seems skipping a gear. So he will test it a little more to see if it’s only a bad adjustment or is broken.

Next I went …..

Low-Tech Sensors

My friend Connor introduced me to Active Surplus in Toronto. Needless to say, my mind was blown by that crazy store. Except for the fact that its not the cheapest place to buy stuff, its every hackers wet dream

Anyway. I found these really neat tilt switches and wanted to build something cool with them.

So I did …..

Just an attempt to create a soft computer interface.

USB POV!

USB POV!

So here it is! uPOV with a USB HID connection to modify the message!

So I continuously recived the question… “How do you change the message?” As I answered this many times before, I began to realize that my “you  use an ISP programmer along with a bash script in linux” answer wasn’t going to cut it for most people. I …..

[Project Log] Custom motorized bicycle Pt.2

Well, today I went to my local bicycle shop to get my nexus 7 rear hub, but it wasn’t ready (the guy has to take it out of a wheel, he’s a lazy guy).
Pissed off I went to the other bicycle shop in town to get the rear rim. The guy lend me a wide rim he had, and i …..
