Motorcycle Ignitor box?

[RobertoIsRad]

Hey guys I was wondering if any of you could help me with re-making this DIY project I found online. Original link is here: http://www.thegsresources.com/_forum...d.php?t=182719

Basically I can't find the parts he lists on digikey but I'm also pretty new at all of this. I've fixed a few electronics and I'd really like to give this project a try. I think the basic problem here is I'm too clueless to understand what he's listing in his parts list...

Anyone have any advice on where to get custom pcbs printed? It seems like the cheapest place I found is OSH Park, anyone care to share experiences?

So here are some pictures and the parts list:



Parts list
D1,D11,D21 = 1N4007
Q11,Q12,Q13,Q21,Q22,Q23 = 2SC1959
Q01 = 2SK163
Q14,Q24 = 2SD977 or 2SD1976
if use the type 2SD1976 you dont need use Z11 & Z21
Z11 Z21 = ZY350v /1,3W
Z01 = ZD4,7/1,3W
R11, R21 = 1K
R12, R22 = 3,9K
R13, R14, R15, R16, R23, R24, R25, R26 = 4,7K
R18,R28 = 300 ohm
R19,R29 = 470 ohm
R17, R27 = 300 ohm 2W
C01 = 100nF/63v
C02 = 100μF / 63V/105°
C11, C21 = 22nF/63V
C12, C22, C13, C23 = 10nF/63V
C14, C24 = 150nF/400V

Most of the parts seem common enough. Are the zener diodes the ones you are having trouble locating?

The parts list doesn't appear to match the schematic where the zener diodes are concerned. The schematic and the photograph of the board look like the 350 volt zener in the parts list has been replaced by a 150 volt and 200 volt zener in series.

Edit: The last place I used for PCB manufacturing was Sunstone Circuits. Search for PCB123 which is their PCB layout software and you will find it.

Re: Motorcycle Ignitor box?

I found the 1N4007 diodes and the capacitors. But I can't find any of the "Q or Z" type parts. I also don't really know what I'm doing as far as getting the right resistors, I get that 300 ohm means I should get a 300 ohm resistor but what about the other specifications? and I don't really know what he's talking about when he puts things like "3,9k". Sorry to need my hand held... I'm able to follow "recipes" pretty well usually, it just turns out I'm a terrible cook...

Re: Motorcycle Ignitor box?

The 'Q' items are transistors and the 'Z' items are zener diodes.

"3,9k" is 3.9K or 3,900 ohms. The resistors are generally 1/4 watt unless otherwise specified, at least for the ones with leads. SMD is probably different but none of those on this board.

The schematic has part numbers for the zener diodes which are more common than that marked on the parts list.

I will check back Monday and help you find any parts that you need help with at that time. Do you have a preferred vendor such as Digi-Key or Mouser?

What temperature range do you expect this Ignitor Box to encounter.

I built a replacement ignition module for my 1983 Nissan 280ZX many years ago and it worked fine until one extremely cold winter. I couldn't locate transistors that would handle the extreme cold so I had to purchase a factory built module. It was fun and very rewarding to build the replacement. Components were more difficult to locate back then.

Great! thanks for helping clear that up, I've used digikey a few times in the past. I'll post back if there's anything I can't find now. Thanks again!
