A few months back my daughter, at the innocent and exploratory age of just 2 years, decided to see what would happen if she took daddy’s brand new £17 OSMC remote and used it as a drinks stirrer.
Her test, involving a pint of squash, resulted in two obvious outcomes – one very angry father, and one very broken OSMC remote.
I tried the rice, airing cupboard and even the hair drier methods, but nothing would fix my dunked doofa – it was pronounced dead at the scene.
Fortunately I have a use for lifeless gadgets – I take them apart, shoot some photos and put them here on my blog. If you read here regularly, you will have seen me do the same with a generic yellow motor and a cheap power bank.
So here we go, another pointless amateur teardown!
It’s a shame my remote succumbed to a watery death, as the outside was still like-new. I’d not had it long before my daughter started her killing spree, so as you can see here, I kicked off with an intact remote:
The first thing to do was remove the plastic shell.
By opening the battery port I found 2 screws that held the case together. When removing them didn’t make the remote fall apart, I used my plastic pry tool to pop open the edges. This broke a lot of the retaining clips, so don’t try this at home if you want to use your remote again:
Is that a word?
Taking away the rubber button layer revealed the top of the PCB and the little clicky-pad buttons behind them.
I’m not sure that’s going on inside these little metal blobs, but it must be some form of tactile switch. They’re too small for my fat fingers and old eyes to dig any deeper with:
OSMC Remote Guts
The PCB pulled straight out of the lower layer and revealed its orange underwear – a little raised PCB section.
This appears to be the ‘wireless bit’ – the snake of copper/gold used as an antenna of sorts. There is also what appears to be a crystal and a big blob of black plastic hiding even more goodies underneath:
The little chip below it has a number on it – HB8102P. A quick Google reveals that this is a “high-performance 4-bit RISC micro-controller embedded with 2TKX12 OTP, 32×4 bits SRAM, 12 input/output pins, one input pin and a built-in IR LED drive pin” – gotcha!
- Micro controller – makes sense, it needs a brain
- OTP – One-time programmable maybe?
- SRAM – memory – a specific type of memory.
- Inputs/Outputs – that makes sense as we have buttons (reminds me of the Pi’s GPIO)
- Built-in IR LED pin – Hmm, I’m not convinced this remote uses IR?
That was a relatively short smash up of Sam Nazarko’s remote design, because I guess there isn’t much to it. A plastic casing, a PCB and some buttons.
I’m going to buy another one as though, as although the remote is more expensive than others, it’s just very good at what it does. The right buttons are there without all the bloat features you don’t need, it works flawlessly with OSMC and it’s smaller and more comfortable than the cheap Chinese versions I’ve had before.
OK it’s a terrible stirring device, but that’s not on the feature list! Here’s the end layout of pieces for all you hardware nuts:
If you’d like your own
stirrer OSMC remote, they’re available for around £16-17 at most good maker stores. I bought mine at The Pi Hut, and they’re also available at ModMyPi and even direct from OSMC themselves.
Until next time…
