Thanks graffian, I think I was about to make that mistake. I'll have to look for that thread, will it still apply to the L297?

I can do the conversion of the schematic
I will definatly take you up on that offer, If you make the board bigger than 4"x3" will i be able to veiw and output it myself? Good info on the PCB fabrication but think it will be too costly for a one off, as i plan to mill future pcbs.

I actually meant discuss with Irving
You've got me sussed, I'll go and sit in the corner then.:heehee:

a single NPN small signal transistor and base resistor on the output would suffice.
Wouldnt this then be the same as using a 555?
