[ATTiny13 5 leds LED chaser]

I’ve designed a series of articles describing step by step all the steps to a pre-beginner (someone who has never programmed one Atmel) to work with microcontrollers. Finally someone can build a LED light chaser, programming a ATTiny13 using electronic assemblies created by him (programmer, board test).

[Unused PCB's - save me from throwing them away!]

I made a set of PCB years ago and never used them

they are good quality through hole,plated PCB's

I believe these are AIN and DOUT PCB's and also the PIC core PCB's

Hopefully someone can make use of these, otherwise i'll have to bin them.

£10ono for the lot( mainly to cover postage)

Post to the UK.

Have you Atmel Core boards ?

[Masking PCB's With Vinyl Stickers?]

Looks good. I did some similar pcb making with photopaper. But lately the results are less then optimal. Maybe i give this vinyl foil a go. Now where do i find Oracal 641 in W-Europe....

You can try not Only 641 but any other Oracal type: 640, 651, 8800. You can go to your supermarket and search for it. Try search for Orafol or Orapaper.

[Using vinyl sticker to manufacture pcb]

There are many methods to make your own pcb. Probably the most used is photographic paper with laser printer. Glossy paper works too, but I've discovered a new material to do this faster, cheaper and more reliable: laser printer with vinyl sticker. You can see in this forum at Miscellaneous:Masking PCB's With Vinyl Stickers?

[Masking PCB's With Vinyl Stickers?]

As TwinX said, for photoetching it would work, but it wouldn't be cost effective. Nor would it work for intricate, small pitch stuff. I don't think you'd be able to use it as a stencil either.

I use a photocopier and standard photo paper, which works just fine.

I use a laser printer and vinyl sticker, which works very well. Look at this: http://electroni-city.com
