gsquirt - finally here - parts needed added

gurov · 2008-09-25 23:10:17

gsquirt is a board that implements 6 relay outputs, a boost control mosfet, launch control input, a map switch circuit, and driver for two waste spark drivers
all on one pcb... with inputs, outputs, and power provided... so you can take a base megasquirt, add this thing on, and actually have features that you'd otherwise have to hack onto a perforated board

assembling one right now.

v1.1pcb will have a copper pour back ground plane.

THE BOM !:

Code::

RESISTORS:

R1 - R6, R11, R12 = 1k   (8 ea)
R7,  R8           = 2.2k (2 ea)
R9                = 10k  (1 ea)
R10               = 100  (1 ea)

TRANSISTORS:
U1 - U6 - 2n2222 T-92 package NPN (6 ea)
U7, U8 - 2n3906 PNP  (2 ea)

MOSFET:
Q1 - IRLZ44


DIODES (10 ea)

D1 - D5, D10 - D11       = 1n4002
D6 - D9 = 1n4001

why are the holes different sizes?

ever look at a diode ? it has a much beefier leg

the ones i have arent...

darsondriss · 2008-09-26 00:46:08

ooh and i spy a wee

wow you sir are a brave soul...i love your thinking and i hope it fucking rocks!...cant wait to hear feedback

gurov · 2008-09-26 05:09:30

HUGE success.. just tested the whole thing all works, hooked up my black box with one of these:

kind of tight on space for the boost mosfet, but it appears to be working, just have to bend the legs inwards.

much better than having this:

bump , updated the BOM ( bill of material ) and added assembled + top + bottom pictures in the first post. total assembly time - roughly 20 minutes

so i can be a cheap ass and buy the 1.4 board, and just add this, instead of buying the highdollar board?

2.2 board. and yes.. while the 3.0 board has the proto area, this is still laid out nicely with solderin components. While oin the proto area you still have to make your own trace and make sure things are going to the right pin

cant wait to get my hands on one.

RedDragonV09 · 2008-09-27 02:41:19

This is quite lovely

whats the cost of one of the bad boys?

$30 bring your own parts. i haven't figured out the cost with parts yet.

out of curiosity.. where did you have these printed?

i'm using them in the boxes i ship out.
