|Build Log| - DIY midi gamepad controller

[DjNecro]

Let me know how it goes... If it works as advertised it would save a whole bunch of code...

[fbonito]

the button matrix is almost complete...


support for the LED


one LED


all the supports in place


all of the LED on all of the supports


everything wired, now i will connect the positive poles

i've a question...

i bought 2 female stereo jacks for line in and line out... but it seams that it has 6 poles to connect... i have no clue how to connect it... can anyone give me a hint?

here are the pictures

You can take your multimeter and measure where the contacts have to be soldered to.

Nice job...

well, i could use a multimer... iff i had one...

i think i will improvise with a LED, using it as a "multimer"

Dude... stop whatever you're doing and go buy a multimeter... Seriously... I'll wait.....................

There is no way you can reliably deal with electronics without one... You don't need a $100 fluke... I am getting by with a $6.99 el-cheapo unit... just make sure it can do continuity, dc/ac and resistance... anything beyond that would be overkill at this stage...

Regarding the 1/8" jacks... is there a part number for them? can you link us to the page you bought them from? I find it a little unusual for a normal headphone jack to have that many terminals... I'd bet they're duplicated (two solder points per terminal) A standard stereo plug has 3 terminals to deal with (ground/left/right)..

lol yeah, my controller is on hold until my multimeter arrives... ordered one off a Chinese seller on eBay for literally $3!

yep! for what we're doing... that's all you'll need. If you want to take it to the next level, then spend the money on a decent meter (an oscilloscope would be better).. All you're buying is more accuracy, faster response times and in most cases auto ranging... Before I'd drop more than $50US on a meter, I'd buy a scope...

i looks like that i've got a stereo jack with switch...

i got it from a local supplier, and i don't have any more information...
