OT p.c.b. etching

Does anyone here do electronics etc as an hobby and do pcb's, not that owning an xm gives time for an hobby............. I need to get a 2inch*2.5inch board done, about 10 times. -- Lez

The more you need the cheaper it gets per board. If it isn't too complicated (not too many holes to drill etc.) send me a picture and i can tell you for what i'd make them. I need to make a couple of boards in the next few days anyway. ST

Its a prototype for a car alarm for myself and some friends, I've designed it, wrote the software for it, and I'm going to put it up on my site as a project for others to build one if they want etc, its essentially PD hardware, and its development has been 'blogged' on digital car uk Just a pic chip and a load of transistors. The very first TT board I did came out like this..... http://homepage.ntlworld.com/tinabriddon/bday/DSC00465.JPG Its spot on, but I have not had a working one since! And these ones are a 1/4 of the size of that one, look! http://homepage.ntlworld.com/tinabriddon/pcb/boards.jpg This is my headache... http://homepage.ntlworld.com/tinabriddon/pcb/stress.bmp

Thats $4 a board. I recommend you simply order them there. If for some unfathomable reason you don't want professionally made boards at this incredible price I can offer to do them for the same, but without drilling. Surely you would have to be crazy (you might be for all I know, if you really think your wife isn't going to suss out the blackpool thing as soon as you suggest as much as going away ;-) ). Convenience and speed seems just about the only reason these days to make your own boards, price certainly isn't. ST

Wondered how you knew, I know she has spies everywhere when I mention cars, then realized I'd posted it in the wrong group! Doh! I just had an idea to get me this batch done, and then the next ones will be at a later date by which time I may have a working system.... The ols artist method for making 'prints' of a famous pic, trace it, prick the canvas, join the dots.... I can print it, prick the board, and using the worlds best resist pen (uniball paint pen px203), join the dots and etch. It wont be a fast way, but maybe I can get the wife to help.....yeah sure!

I made PCBs like that, 30 years ago, using cellulose paint as resist. I got quite good at it, and even managed double-sided boards.

Have a look at ebay item 7555760923 or 290077371461. They are offering fairly cheap manufacturing services. It saves a lot of grief and you end up with professional looking boards. Les Lez wrote:
