Didn't think this warranted a new thread so am adding some photos here. I recently picked up a faulty V1 remote which said it worked but didn't rotate smoothly. I didn't bother to test it and went straight to disassembling it so can't tell if it did work properly before or not, but the turning did have a bit more stiction than normal. Anyway it turns out it also had had a leaking battery in the past, so I cleaned it up best I could and had a look at the bearing. Couldn't find anything else wrong with it but after cleaning up I reassembled it it seemed to work ok but would occasionally not register and need additional turns. But it would also rub a bit, and I'd left a small piece of plastic/dust in the window which was really bugging me, so I went to disassemble it again and accidentally tore off a small SMD component, I think an inductor (the round component with an E written on it next to the bluetooth module). Now after reassembling the volume only fluctuates about the current setting +/- 1. So I broke it for real! I found the most difficult part of the disassembly was to remove the bearing, as I don't have a bearing puller.
Anyway the main components in this if anyone is interested are:
Microchip PIC24FJ128GA306 128 KB Flash Microcontroller
Microchip MRF24J40MA 2.4 GHz ZigBee/MiWi module
BlueCreation BC118 Bluetooth 4.0 module
ADXL362 3 axis accelerometer
NSK 6809V bearing
I can't see any markings on the two encoder sensorsĀ
Interestingly the PIC has a built in LCD driver, so maybe they were going to include a screen with the V1 remote and dropped it, keeping it for the V2 remote instead. Who knows.
