(Was Pouch to kill time) - Cinnamon Mintypi Project Finished!
Posted: Wed Jul 18, 2018 7:31 am
My project has Finally started 
After holidays, kids going back too school and lots of things that needed to be done i finally found some time...
I just finished soldering the really tiny battery monitor parts
and the screen.
TIP: when soldering smd, use flux, always...
Yep i know, there's a bridge between pin 9 and 10 the traces where really close, i already posted a question in the help section if this could cause a problem (think not both are 3v vcc & anode lcd).
Edit: as i already expected, Helder confirmed this is not a problem (9 & 10 are connected on the pcb)
Finally, raspberry zero W's where back in stock with my supplier (had a 1.3 but wanted wifi...).
So after some serious soldering,
Behold it's alive....
Found out that cutting the solder (1mm thick) into little pieces (aprox 2mm) and sticking these in the holes that need to be soldered worked flawless.
When you apply heat, the flux in the solder can do a better job, instead of most of it burning of on the iron.
Most important, everything is working (for now), including the battery monitor.
I'm pretty experienced at soldering "through hole" but this was my first serious go at smd.
So I'm really pleased with this result.
Next will be cutting the tin (yes i am working the other way around
) and adding sound and button's.
Ok buttons are go...
And power...
And finally, to turn it on and off...
The wiring is done, all with silicone wire.
Made a heatshield to protect the lipo with two layers of aluminum tape stuck together covered in non conductive mylar tape.
Tested with a soldering iron set at 80 °C/176 °F could keep my finger on it with no noticable heat development.
And last but not least, the end result...
That's it for now.
Will keep you updated!

Thanks to Helder an Wermy the parts for my first MintyPi are on their way!
So to kill some waiting time i started on a storage/carrying pouch.
In a second hand store i found this nice retro looking pouch for only €2/$2.40.
Its a (70s ?) pouch that used to carry coloured flash filters, and with only minor modifications is a perfect fit for a Altoids tin.
Had to make two slots on the sidewall's, so the curled edges that are on the lid of the tin would fit.
Now the tin just "floats" in the pouch with just enough top and bottom clearance, so sliding it in/out will leave no marks.
Not sure of making a belt loop, maybe a bit to nerdy/geeky
Hope you guys/girls(?) like it.
