I added some pictures and text to the Jujubee page.
I’ve been having some trouble getting my altimeter to fire my electric matches. I don’t have any low-current e-matches and I can’t buy them except at the launch without a LEUP (low explosives user permit), which I probably couldn’t even get given where I live. Anyway. Matches aside, Jujubee was all ready this weekend for a motor-free test shot out of the cannon (no rocket engine, since my ignition circuit isn’t done yet). Gotta do something about that soon. If I can just find my nichrome wire I can try and scratch something… The steel wool bridges weren’t working on the altimeter this time.
The ignition circuit has almost been completely designed. Basically the only thing holding it up is my laziness because I don’t have all the parts in my library already and I’m getting tired of making them myself. But it’s really close. Once it’s designed it should be a fairly simple matter to etch the board on my mill using pcb-gcode (which is fantastic, btw). But then I still have to design and make the wireless arming box, and THEN write the firmware for BOTH devices. Yeah. Less than 2 weeks left to do all that in my free time? I’m a bit skeptical myself.
