… or I just had few spare hours 😉
< intro >
From time to time I feel a need to work on something else than refurbs and repairs, so this time, I have another fun project to cover that I’ve worked on some time ago. I’ve worked on similar projects before and even documented ’em all here on the blog.
The first attempt was an interesting journey – https://retrohax.net/project-retroblade-v-0-27237-part-one-2/ but later I did some upgrades which resulted in a way better outcome – https://retrohax.net/project-retroblade-evolution-part-two/
I had a few spare hours the other day and below you can see results 🙂
< /intro >
I’ve started off with dumping all items on a table that I’ve gathered during the past months. Well, maybe not all but only the most interesting stuff 🙂
I had two Sony PSP handhelds and both were broken in some way. My idea for this project was to use PSPs case and put RPI Zero inside along with all other parts that would form a fully functional retro platform. Obviously, I wanted to use awesome RetroPie as in previous projects.
Woohoo! Perfect fit 🙂
Tiny USB powered Li-Ion charger with my dirty hack to deliver LED light to an edge. It was made out of transparent 3D printing filament lol.
I’ve realized that It would be cool to use and connect original pads to RPI Zero. That turned out to be a quite challenging task.
My idea was to cut a piece of the mainboard with ZIF connector in it and then solder wires directly to a PCB.
Now, here is the tricky part 🙂
I had to use my USB camera to solder all tiny Kynar wires to pads on a PCBs.
… kinda hard task after having three coffees lol.
While trying to run the whole system off a battery, I’ve noticed some voltage drops. I had to crank up a voltage a little bit because LCD didn’t sync correctly.
I chose a standard voltage step-up converter.
Testing again, but this time with RPI Zero on board.
It turned out that back-cover will not fully close because the battery was too thick lol.
However, that case wasn’t fully lost because right after realizing the above failure I’ve noticed a pile of old Nokia cellphones lying around …
Instantly I was like …
Here is what followed.
Some final testing and that’s it! 🙂
