555 pcb
m3vuv:
hi all ive been working on a 555 timer project,got it working spot on,thats on a breadboard,i have to get something built for the 5th sept to demo,im having issues with my pcb design software,will attach the schematic,would anyone help by trying to knock up some pcb artwork for it for toner transfer,the resistors are going to be pots mounted off board and the caps are a standard disk ceramic and a small 10uf radial electrolytic,size isnt an issue,thanks in advance m3vuv.
m3vuv:
the sounder isnt needed just a cpple of pads to connect a mosfet offboard so just 2 solder pads.

Your home brew spirit is to be admired but in this case there is no need to reinvent the wheel:

For about 15 GBP (Conrad are in the UK) you get a PCB and all the components plus a decent assembly manual. I've been doing electronics for over fifty years yet I still buy these whenever I need a timer for something because they're so damn convenient.
