@Twinsen I know what you mean, I always find thumbwheels very unnatural to operate.
@solidgeek It’s 2 PCBs stacked on top of each other, the DC booster, Lipo charger and NRF module go onto the bottom PCB (not seen in the image I shared).
Here’s the top PCB, some of the pins connect to the bottom PCB (NRF and Batt pins)
Here’s the bottom PCB which holds the DC boost, lipo charger, 10k resistor and 220uF cap, the NRF module is soldered to the back (pins running down the right).
The PCB just reached my post office, awaiting for it to be delivered to my home. I should be able to get it by the end of the week.
For those interested, I used EasyEDA for this, drew the schematic but I had to customise the board layout as they did not have most of the parts in the library.
I’m a total noob at this, and this is my very first DIY PCB so I’m keeping my fingers crossed that it turns out well. I could have saved a lot more space by compressing all the components into a custom board with inbuilt regulators and such but I have no skill to do something like this, so it’s just off the shelf components which then get soldered to the PCB.
As for the enclosure design, the trigger works well, nice and smooth because of the bearing (still some friction due to spring arm and all). However I ran into some issues with the buttons, will need some adjustments to make sure they work well and don’t get stuck.
