Picaxe I love them, so quick and easy to do what ever you want. and best thing is no programmer necessary. I've played with a similar dimmer project recently. Below is the code I wrote for it. I know its not very elegant but I was in a real hurry.

This turns off at 0 volts to almost fully on at 5 volts.

let dirs = %00000101

SYMBOL TADC = b2

High 2
pwmout 2 off

Main:
readadc 1, TADC
Select case TADC
case 0 to 33
         pwmout 2 off
Case  33 to 90
        pwmout 2,99,360
case  91 to 189
        pwmout 2,99,340
case 140 to 195
        pwmout 2,99,300
case 195 to 199
        pwmout 2,99,250
case 199 to 201
        pwmout 2,99,200
case 201 to 202
        pwmout 2,99,100
case 203 to 210
        pwmout 2,99,45
endselect   

goto main

David, you reading this? can we do an episode on PICs pleeeeeease! a "Build your own dimmable, programmable portable bright light" episode using a PIC as the main controller would be ideal, just think, you get to play with LEDs and PICs!

I would like a flashing function for my future bike lighting setup, so using a PIC for the control box on the handlebars with some FETs or something (for the up to 2A @12v power requirement of 300 LEDs) could be the way to go, right now I've kept it simple by using switches for different light levels because there's not really much to go wrong.

Wish this thread was integrated with the other show ideas in here.

I'm Talking about PICAXE's, not PIC's, PICAXE is a pic with a boot-loader installed. The code is written in pbasic, and is uploaded via serial through just 3 pins. And they're cheap as chips . http://www.rev-ed.co.uk/

The code from above was driving a large 100amp fet through a mosfet driver, I could dim a large car lamp, driven from a car battery to a very fine amount. In the end it was used for controlling a hho tank in a car, drawing 20amps.

Your flashing idea could be achieved in around 5 lines of code(it's that easy, really!!).

Looks like PICAXE is the ideal way to get into chip programming, I taught myself Basic on the ZX Spectrum & BBC Micro back in the 80s and even wrote a simple programming language within that language on the BBC. Bit rusty now in the ole programming stakes but I can learn fairly quickly.

In the March 2008 issue of Nuts and Volts they show how to make a rail gun. and there have been many shown on You Tube
These gun are able fire menetic objects varius distances varing on many aspects of parts i think i would be a great project to show how to make one

[melmaks]

Rail guns are becoming more comin to hobiestest and they can fire a veriety of objects at various speeds and distances varieing on parts

How can I get car amplifers to run on AC?

It's really easy. You buy a plate amplifier, mount on your enclosure, plug into AC and connect to your reciever. Done.

Well here is some thing i have been thinking of...

Home VPN.
Through "Site-to-Site" VPN or roaming VPN clients like OpenVPN.
Difference with static/dynamic IP, NAT-T and more..

Timer activated blinder lifter.
In the morning, the blinders automatically lifts and let in the sun. So you dont have to buy a Philips wakeup light....

A railgun from scrap parts would be pretty cool. You can get capacitors from old disposable cameras and I'm sure there are designs all over the place.

To expand on it, you could set up a shooting gallery too.
