Hi any metal workers on this forum ; I need a few parts made in nickel silver. I have some in brass so Q2 does anyone have a supply
of nickel oxide or nickel acetate. Or know a reasonable Ni plating company Ni/ PTFE would be cool.

My I suggest a project for this club; An autonmous E match chaser. Revolution Electronics sell a small card 6 cm by 5. That has just two chips A PicAxe 18x and a ULA 2003 octal power darlington. The picaxe does not need a programmerjust 3 wires to your PC. Its huge advantage is It understands basic. The comet chaser program below tookme just an hour. As opposed to a week in ASM . The 2003 provides 8 independent Qs to sink 500mA at 48 volt. Fabulous Fireworks and our friends at Pirotecnica Europla will sponsor the project to 70 euros. in components. If you want more than 8 Ques just take Q8 into the input of another module. This is the big idea, instead of just chaining the modules they could be networked. Then if one nodefails "the show can go on." no more no fire system! I can do the electronic design. I would like someone with a nice circuit drafting package and we needa rack of 8 tubes. This is an example program shows how easy it is:
