Is there interest in a new BASIC compiler for AVRs?

I want to find out how much interest there would be in a new BASIC compiler for AVR processors.  I have been working on one in bits and pieces for about a year and a half.  I would like to get motivated to complete it, so I want to know if others would be interested in it.  This is a VERY large project, so it will take a lot of time.  It will be about 10,000 lines of code for the first useable release. If I really get going on it, I think I could have an initial beta release before fall. My motivation level will be directly proportional to interest.

Walzing Hard Drive Motors

Update: This page is just an archive. The real work is continued as a walk through. Please direct all your comments to that page.



I am the proud owner of a stack of scavenged hard drives. I hoped to find really fast, torqueless motors inside. But instead I found myself a project for my new found 555 knowledge.

Are we too many in here, should we start limiting acess?

Hi everyone :)

Are we too many in here, should we start limiting acess?

I have had the same thoughts before; at a point I felt like we where so many in here, that it was impossible to follow everything & everyone..

It sure is now.

Last time I did & said nothing, and it turned out to be the right solution; So many cool people dropped in, people I would never have known else. I am thankful I did not limit acess then.

After a long hiatus, I decided to resume working on this project. I bought a USB power supply, that easily powers the Pi with the camera module and wifi dongle … Read more

BoB the Biped and Me: We celebrate the Seahawks! (updated)

Just a place to put a link to the video of BoB dancing while I applaud. I'll update with more info in the future. Gotta meet my buddy at the pub in a few minutes, hence the brevity.

There are four total dance moves, I think the video only caught three of them (they're randomized).
