Here's my story on my journey over the last year to resurrect Pulsar LED watches......I've been a bit busy learning PCB design and more importantly micro RISC programming..........
FIrst here is another broken Pulsar LED. Broken wire bonds doh....
Next step bring out the veroboard abnd start programming......
Brush up on basic PCB design and get busy with the laser printer, iron and ferric chloride
My girlfriend calls it a watch for Elephants !
check out my next installment - Here's part 2
My last post showed my LED design journey learning PCB skills and more importantly programming. Here I'm trying to miniaturise.
Here's one of my attemps to build a very small PCB at home. Drilling 0.3mm holes was a challenge.
Problem is it was too unreliable mainly due to homemade vias.
Only one way to go from here have proper PCBs manufactured.......
Here's the jig I tested and applied yet more programming time !
Sadly I killed the main display, so i'll ask again...Please does anyone have any dead p4 modules I could buy ?....Please ?
At this stage I moved on to another Pulsar the brilliant 3013 module....[
In my last 2 posts I made a valiant attemt to repair from scratch a Pulsar DOW module. I very sadly killed the display with too much heat
Oh well don't give up I'll try fixing a 3013 module using my new skills.
Here it is all nicely asssembled under my microscope.
And here is my fully working baby.
it's taken me a good part of a year to get here but it works.
Oh what fun
