AVR design contest

Atlmel is holding a design contest that is likely of interest to many LMRtians.

Cheap and small swarmbots

So. I'm finally building swarmbots. My goal is to have bot that is small (should be 25mm x 25mm, will be ~30mmx30mm) and cheap (less than 50$ per one. even when building only one).

 

 

Atmega + camera.

I have thought about atmega + camera idea too, but for use on atmega not sending. I looked at CMUcam but it wasn't so low-cost as it was advertised (100$ it too much). I found http://www.robotshop.us/sfe-cmos-camera-640-480.html . It seems cheap, microcontroller friendly and so on. Only problems are - SMD connections, killer programming and impossible debuging.

 

So, all thoughts and good links are welcome.

ATMEL or PIC

Okay, this is just a little "this vs. that" quiz so I can find out what you guys generally prefer. Vote PIC for PICs or PIC based devices like PICAXEs and ATMEL for ATMELs and stuff like Arduinos.

DIY CNC Part II

26/05/09

2 more draw slides to use for the Y axis purchased from here. High quality slides with ball bearing inserts. Still have to work out how I want to mount them. They were only $15 each.. money well spent now that I can see them close up.

ubuntu & atmega

So my pickit2 kept failing, even with only pic in circiut. FinallyI got fed up of pics and windows. I deleted windows, moved to ubuntu, took out mu usbasp and atmega88. Tried to get pickit analyser (like computer oscilloscope) working on linux but it seems impossible, so I have to use windows computer for that. I also found out that linux + pic programming = big no no.

 

Fun with timers and interrupts on Atmel Tiny26

A long time since my last post on this site... Anyway I've been experimenting a little with my Atmel Tiny26 uC today using AVR Studio 4 for development and the AVR ISP mkII programmer to program the uC.

$10 logic analyzer

After a lot of umming and ahhing and general procrastination I decided to dig this out of the cupboard to give it a whirl again.

ATMega32

I recieved a surface mount ATMega32 from futurlec instead of the through-hole version. I have no use for this, as I have no tools to solder such small surface mount stuff. If you have another type of AVR you'd like to trade, please let me know, or if you'd like to buy it off me for like $3 or something. Can be sent by standard post.

AVR is in the house!

Last week I purchased the AVR ISP mkII programmer for the Atmel AVR series of chips and I had previously bought some ATtiny26 chips for use in motor controllers, line sensors, etc.

The AVR is a microcontroller developed by Atmel. Its an 8-bit RISC μController based on the Harvard architecture which physically seperates the data storage … Read more
