decided to do a little write up of a det can I made the other weekend. All of the parts were ordered from Jaycar. Kind of sucks the shipping cost more than the parts. The only parts that arent on there are a piezo and the 1/4 in headphone jack which I already had from building guitars. All together under $40 to build and pretty easy as long as you can solder.
part list


All of the parts laid out


Everything soldered to the board. The kit comes with instructions. The only two changes are soldering a jumper instead of the 1k resistor and soldering a POT instead of VR1


Back of the board


Soldering the piezo


Everything laid out and soldered



Drill some holes in the box and attach the components. I used hot glue for the circuit board and battery holder



And the finished product


I haven't had a chance to use it on an engine yet but it will defiantly work. I still need to decide if I want to use a battery clip or a eye clip to attach it to the engine.
I will most likely use an aux cord and run it through audacity on my laptop that way I can record it. I'll use my phone to dictate also.

If anyone has any questions feel free to message me

 

That's bad ***. I paid almost a grand for my det can (back when I had money laying around) :/ You're getting most of this done for less than 1/30th of what I paid.

 

Very nice! Kinda sad that half the cost is shipping

 

I know. Took forever to get here too. The company is in Austria. I'm sure that there's companies in the us that have the parts.

 

I usually use Fry's or Tigerdirect for the little bits n' pieces like this.

 

I forgot about tiger direct. Next project will be a turbo timer so maybe I'll order parts from them
