Firstly, many thanks to moosepr for putting this kit together and sharing! :D

It's really cool.

I was lucky enough to get in on the first run of orders and receive TP002! (Thanks for the bonus gift and Haribo!)

Having had to wait for a new supply of Pi, my build was delayed so I spent some time printing off moose' build guide and getting all the required parts together.

This project requires some fine soldering as moosepr advises. If you're lucky like me your short range eyesight is a lot better than your long range so glasses etc weren't required but take into account its super fiddly in some areas....the resistor for example! Don't overdo it with solder or leave your iron on too long.

The advice found in the guide to tin one pad, leg (tactile) switch is golden so please follow the guide to a tee.

It's really good idea to use a 3rd hand / magnifying glass to check for bridges between joins etc.

As for this build, its not quite finished yet. I haven't wired the battery or power supply on as it got late and so I just tested via 5v USB on Pi.

I also plan to house in the 3D printed case, something I've started producing already.

Also mentioned in the guide there is no room for test pads so if you're doing this project, solder as best you can using flux for tougher pins (GND etc) and then test.

Moose was kind enough to provide me with a schematic and some info so I could target those specific pins where I had issue.

On first run the screen never worked - this has now been fixed post some reflowing :mrgreen:

Currently all that's outstanding functionality wise is the joystick so i'll work on the GPIO pine in due course to rectify.

One thing I did deviate from the guide was the screw placement when soldering. My PCB started to bow outwards so using the screws on the back held the pi and PCB firm without this effect.

Here's some build pics so far and useful links:

Awesome work, im glad you are enjoying it :)

If you thought the soldering was tricky, wait till you try and get that case under the screen :P

Your photos look better than mine too :D

I don't think it existed when Santa was about! You can find the guide here

I do plan on doing some videos too, once I can work around my pathetically quiet voice πŸ˜€

Finished this little beauty off now :mrgreen:

Had a bad GND on the joystick which, after some flux and solder work was all sorted.

Really is a great piece of kit and fun to build. I havent actually finished printing my case but I'm waiting on a smaller battery to allow it to fit.

Im also looking at tweaking the files to accommodate it as is but im a novice with 3D print design so dont get your hopes up :lol:

The battery im using is a 500mah, originally bought for a future VMU build. Fits a treat for the 'naked' look at least.

Used a couple of bits of VHB tape to keep the charge module and battery in place. Also laid a bit of kapton take across the pi prior to this for easy VHB removal and to protect the pi from the charge mod.

As for the charge module itself you'll note the resistor replacement to a 2k2. This is to bring that charge rate down from 1A which was too high for the 500mah lipo.

Again, a big thanks to moosepr for his work on this and for answering my questions 8-)

This will accompany me on my commute tomorrow....roms scraped and ready for action πŸ‘πŸ»

Instructions on the web site broken :-(
Can someone fix? Or provide me with full instructions, please?
