Just staying true to the guide

Drilling the trigger buttons holes was quick, but as Wermy advises start small and work your way up.

As for the filing, I'll be honest, this took longer than expected and i miscalculated the noise level involved so spent the evening out in the shed

Fixing the 3D print screen housing in place went perfectly. I dont actually have a roll of VHB tape but have pre-cut squares of it left over from dash cam mounts.

Test fitted the tactile buttons, power switch and micro USB charge cable to ensure all holes were correct.

That'll do for tonight

20/07 - Didnt have much time today but managed to mount the trigger buttons, solder the wires and glue in the base plate!

22/07 - Time to work on the PCB / Screen - I'll be honest, had a couple of issues here although everything I needed was already on the forums.

Started off by soldering the PCB and Pi together as per the guide, even using those extra clamps to ensure there was no movement. 100% recommend a multi-meter here to test continuity.

Couple of holes needed a tad more soldering to make the connection but all went OK.

I then trimmed the ribbon cable for the screen usung a scalpal which was easy enough. Didnt have much success locking the ribbon cable in using masking tape, however opted for a slither of electrical tape which worked a treat. (photo taken before i swapped!)

Upon completing had the 'white screen' as noted on the mintyPi hardware forum. Re-checked my soldering and the 5V was slightly temperamental so re-flowed that hole. Still found I had the white screen. Bit more reading up online and i went back to re-align my ribbon cable....success. Just needs to be placed nice and accurately.

Here it is working as expected:

I also hooked up my USB sound card to test.

Have now prepped my soundcard for use inside the case along with the battery charger.

More to come.

28/07

Finished this build off! Had some white screen issues which are now rectified. Everything was plain sailing from there however

Except that is... trying to get solder to stick to the main GND pad was a pain!

As for the mintyPi itself, really impressed with how it all fits together and the screen is actually really impressive.

Thanks to Wermy and Helder for all of their efforts on this one. Such a great project.

Now to carry on with the other builds.....i note Wintergreen has nearly caught up in the poll

Here's a pic of the finished build:

looking good! and yeah... Oh man. the filing.
the prints took over an hour in total for me, and I was still doing the filing when they finished. I still need to do a bit more too!

I think I might tweak mine a bit more, too! Wermys example in the video is particularly impressive.

I wonder if there's a set of tin punches out there as this will no doubt be my least enjoyable part

If you have a dremel, some tiny bits and a steady hand you can do 90% of it that way and then just finish off with the files to get the edges nice and clean.

To be fair you did mention this in the video. I do indeed have a Dremel with some finer tips so ill try that next time for the bulk of the work

I used a drill press (pillar drill over here ) for most of it, then finished with the files.

Hey I've not lost my English tongue

more for wermy's benefit

loving it so far....

i was thinking about putting some kind of support in the tin (maybe a small piece of wood), when i go to drill or pierce it...


but really looking forward to all the builds that are gonna start flooding the site....

That's not a bad shout! Im looking forward to the ingenious methods people come up with on this one.

Had a quick look for USB esq' punches but nothing cheap and cheerful so dremel it is for me. I also found that my super fine tipped hand file created a small hole with a little pressure and many rotations. Possible alternative so long as you're careful.

Loving the build so far though although I have burnt half my tongue off on those Peppermints
