I know I'm coming in a little late ( as usual :wack: ) but I just wanted to throw my hat into the fray and offer to get and burn the pic for you John. I cant make PCB's yet, but I guess I could botch something together out of stripboard if it was needed. Tim |

And back on track... How many people would be interested in a 'kit' of parts? I've only done some preliminary research but I'm guessing the components would run to around £15-£20 (no connectors, presume soldering wires to the board edges for connections) with pre-programmed PIC's, and with say 10 people on board PCB's would run an extra £10-£15. On top of this to complete the whole thing you need:- A keypad (£13 ish from Farnell if you used the one I use), a box (say around £10). Then depending on what you were driving - but lets say a typical 4"-8" rotary or lathe head or similar dividing head, then:- Stepper motor (say £25), along with a stepper motor driver (typically around £35) and a power supply (say £25). Some savings can be made, you can find cheaper drivers or even make one (say using a L298/L297 pair for around a tenner), laptop power supplies (18v plus) are ideal for driving this and can often be found v.cheap or even free and a bit of digging around may find savings on the keypad (or you can make your own) and stepper motor. Finally you can build it on strip board saving the cost of the PCB, although the more people were interested in PCB's the cheaper they get - e.g. aprox £100 for 10 and £250 for 100 (assuming my original PCB design can be used). |

Not sure where the queue starts, but would like to put my name down please. Pete |

Hi Kwackers, You can put me down for a kit, or just a PCB if that'll help. Bogs - I'm sure young J45on will do a fine job, but if you need someone to solder a kit together, give us a shout. OT: I've been browsing most of the engineering forums for a while now, and it is remarkable, out of the hundreds of semi-anonymous posters, how just a few names stand out as the advice and assistant providers. Bogs here is one of them - treat him well or bemoan his loss! Bill |

Hi Kwackers, put me down for one please,if you decide to offer them, I would certainly be up for a kit :thumbup: A proper printed PCB would be very helpful to ease assembley :dremel: Cheers Rob :thumbup: |
