Minipov clone

Post by zignig »

Greetings Earthings,

I have spent yesterday and some of today making a clone of minipov3. I have used an at mega8 ( as I had some in my little plastic draws ). Following is a photo of the finished device.

I have hacked up some of the code from the minipov code zip file , and some of the code of this forum.

Some changes I have made to the code.
- Brightness control using software PWM on timer 0
- Multiple patterns controlled via a four way DIP switch
- Internal pull up resistors used instead of discrete components

The main reason I made this a friend is doing some 'light painting' with his digital camera ( very long exposures ). He is not an electronics guy so I wanted make it so he could use different patterns.

The big green button is unused at the moment , it is attached to pin 5 port C. I have not got a schematic of the circuit I just made it up as I went , if anyone is interested in I can make one up and publish it here.

I have attached the code to this post, some thing to note. the brightness is set to full (255) and the scan has been slowed down from the 400hz standard as it will be used for light painting.

cheers

Simon :D
