Programming a Picaxe in Ubuntu

Well, a small comment in the shoutbox caused several guys to download Ubuntu. Good choice, I like it! Here's a walkthrough to programming a PICAXE in it.

 

STEP  1) Download the Linux Axepad here- http://www.rev-ed.co.uk/software/linaxepad_100.tar.gz

STEP 2)  Extract the files to a folder on your desktop called "LinAXEPad" or whatever you want to call it.

LASERS!!!!!!!!!!!!!!!!!!!!!!!

So I have this laser tube lying around and I was wondering how to use it. It is a Helium-Neon (HE-NE) gas laser tube built by Uniphase.

It's description is very vague, I'll read you the label.

Problems programming...

I have been using my PICAXE 28X1 board with success for a while now, and I decided to move on. I have breadboarded a PICAXE 28X1, but programming success is a little iffy. 99% of the time, the download page comes up with a normal downloading screen, but only one dot loads.

FAIL!

Custom project board in progress...

Hi, I have a spare PICAXE 28x1 and L293D that I want to use for my first custom built circuit. But i have no clue what to do!!! The diagrams on the Picaxe website are so confusing and the ones in the manuals only show the pinouts. Can I just hook up 4.5 volts? Or do I need fancy shmancy support circuitry like capacitors and stuff? 

Thanks guys! 

UPDATE:

I have a diagram of the L293D and it is nice to have, but very confusing.

Ok. I have started my first custom robot! I'm going to call him "Luigi" cuz he was going to be controlled by an Arduino, but I decided not to. But its a cool … Read more

Reuse Those Servos!

I'm kind of new here, so here is my first post. It might seem dumb at first, but I think it's a great idea. I've read a lot of posts about people frying their servos (hint: fritsl's cheap tiny blue ones, said so himself! :), so I came up with a money saving solution. REUSE THE SERVOS! YA! 

Servos are expensive after all, and they do have some good gears and they mount easily. So if you fry one, I wouldn't panic too much. 

See, why would you want to spend money on this-
