Re: Anyone have a box for the Tracer Injector v2 Kit
toggle quoted messageShow quoted text
Ok, I see that the depth of the cast must accommodate a 13.4mm tall cap, but it can be taller and the board mounted on standoffs (unless one can find such a shallow case as 13.4 mm)
I didn't see what length and width is needed for `the circuit board to fit inside the case.
I bought a box of Bud and similar cases at a hamfest (back before COVID shut 'em down) and they vary in sizes from the smallest, 65mmx40mm & 27mm deep on up to larger sizes. Also I have the larger size Altoids tin which is 90x55mm & 18mm deep. What is the size of the circuit board?

I'm rounding to nearest 0.1 mm, I'm using calipers that claim 0.01mm accuracy.
Top of board to the bottom of approx solder connection on the bottom of the board ~ 3.7mm
The top of the board is far more complex. There's a slider on/off switch, two connection ports to plug the probes into, the vertical caps are taller than the case of the volume control.
Board thickness ~ 1.6mm
bottom of board to top of stereo socket case ~ same as top of on/off switch case: ~8.4mm
bottom of board to top of tallest vertical cap (10uf) ~ 13.4mm
Probe ports, bottom of board to top of these: ~ 14.3mm,
bottom of board to wide section of probe ports: ~9.7mm
NOTE: the probes should be able to plug into these to touch the top of the wide section.
DIA of the ports 10.8mm (10.82mm)
Bottom of board to top of volume control case: ~10.0mm (9.95mm)
Bottom of board to top of volume control stem: ~22.3mm (22.26mm)
If this stem is 22mm tall and the case is made to just match the height of the tallest vertical caps there's about 22-13.4mm ~ 8.6mm for a knob to slip onto the stem. Looks good.
However, if the case has to clear the tallest caps at 13.4mm then they are taller than the stem of the on/off slider switch and an extender will need to be made for the on/off switch stem.
Top of tallest cap ~ 13.4mm, top of slider stem to bottom of the board: ~12.6mm.

I hope that helps and is not too confusing.

What are the dimensions of the tracer injector PCB and the height of the components?
