Version 4 Micro Processor Pulse controller

[CLaNZeR]

I started this thread over the weekend and it got expanded abit, but it got lost when the server had to be restored
MrMamos gave me alot of feedback and started making the PCB's to try it out.

Basiclly it just stated that due to the feedback I have re-designed the Micro Processor Pulse controller to be modular and you can see the protoype below.

You now have a Main Board that controls the communications back and forth from the PC and also programs each Modules Processor.

A max of 8 modules can be attached and each module has a Fet and a Opto Sensor attached. This is now controlled via a dedicated Pic Processor and also monitors all of the other 8 opto inputs.

I have updated http://www.overunity.org.uk with more details.

This week I am working on the Pic Code and windows App and will release details when done.

Find below the PCB layouts:

Managed to keep them single sided with a lot of wire links, but this should make it easier for people to make.





I will release the Hi-Res images as soon as it is all tested.

Excellent mate, I made the tracks and pads a bit bigger than usual and avoided running tracks between pads, as know what a pain it can be when etching your own PCB's.

Shame the post did disappear as we covered a fair bit on the pin configs and stuff, but I have updated the pages at my site, just in case they go again.

Be good to see any pictures you got.

Nice clean etching
What are you using for developing?, very impressed must admit.

CNCDuDeZ is my site, started as a hobby but did not expect the demand to be so high, so knocked it on the head, so I could concentrate on doing stupid stuff looking for OU LOL
I will try to get back to it, when I have got this stage of my life out of the way LOL

Must admit it is handy letting the CNC machine do the drilling, it does not do a bad job of tracing the PCB's out either, but I have to order some more fine bits, hence back to the etching at the moment.

I use the Mplabs/Mpasm compiler with Pic basic as the PBP compiler does not support the new 18F chips yet.It is handy when programming the new USB chips.

The 15Pin DB's are RC's so yep two rows as easier to layup again.

Did not get time to work on code tonight, as the guys dragged me out for a bit of food and a few drinks, but tomorrow night I will crack on.

Hi Mike

What do you mean picture paper and Iron on?
I have used that blue Iron on paper before but must it admit it was a nightmare.

I just print out on clear laser acitate and expose with lightbox.
I messed around for years using different developers and caustic Soda but now find the seno applicators the best.

Regards the machine, I may have parts for a frame and set of motors but probably not the  controller box. Would love to help you out in the future, but at the moment I find it hard to find 5 minutes when back home at the weekends as it is. I am planning to have a months break in about 6 weeks time, where I will then be able to catch up on stuff back home and maybe help you out.

I have plenty of carbide bits, but thanks for the offer. The ones I use when tracing out PCB's are really fine point and expensive, which is not good when you snap one grrrrrrrr LOL

Will be staying in hotel room tonight and not going out, so will crack on with the code so hopefully can try it out at the weekend. Then the boring task of making another 7 module boards so I can test it all with them all connected!!
