I have attached an image that shows the little 8pin PIC stuffed inside the battery box. I have also attached a short video to show the light effects. I think I managed to capture the candle flickering effect, but not sure how well it will come up in the video. Unfortunately, these cheap battery lights just have all the leds connected in series, so no real opportunity to to drive multiple outputs. The idea could easily be adapted to lights with multiple circuits. Peter.

Ho Ho ho. Xmas is coming again. I have updated my Xmas lights code from a few years back. Essentially the same functionality but this time with fewer components. The entire project is based around just a single PIC micro. I used a PIC12F617, because they are small cheap and I had a few lying around. The new design does away with the need for an external driver transistor/mosfet. The code uses a slightly modified version of the standard GCB software PWM routines to enable the use of 5 outpit pins...

Hi All, Its Xmas so I thought I would share this simple project with you. It is a very simple Xmas lights controller, designed to be retrofitted into a cheap battery Xmas lights system from your favourite internet shop or local junk store. The code should run on just about any pic/avr micro. No special peripheral hardware is need. My h/w consists of a cheap battery Xmas light string that my wife acquired for $3 at a local junk store. The electronic components are nothing more than an 8 pin PIC (12f617),...

Hi All, Its been a while since I have been on here. Which is actually a good thing as I have been successfully using GCB now for 10 years or so. However I have run into an issue with a current code build. I upgraded to a later version of GCB recently and now a bit of code that used to work now fails at compile time. I was wondering if anyone has suggestions on how to fix/workaround. Essential I am trying to implement a good old fashioned jump table to create entry points between pieces of cade that...

Yes. I fell into this hole before, but had forgotten about it. A very easy mistake...

Hi Guys. A frustrating little bug that needs fixing. It you accidently type a decimal...
