Yeah i know, those things always crack me up. Like gold plated ak’s and whatever, most people would only see the business end of any of mine anyway.

Lol if there’s any gun I’d ever own that’s gold plated it’d be an AK with custom furniture.

Love my custom furniture, just dont see the need for all the other stuff. To each there own, they do look cool.

I’ve got one of those same Corsair RGB mouse pads. My daughter is entranced by it every time she comes into my office.

It’s funny but the LED mouse pad type things are literally the exact type of “lets slap unnecessary lights on” object I’d normally talk hella shit about…BUT OOOH IT’S GOT A USB PORT TOO NEVERMIND NOW IT’S AMAZING!
I’ve been working on an openhab server/config/layout for about a week now, still in the formative steps of getting used to it all but the objective is to get all the Office lights to play nice together - Sengled wifi bulbs in the ceiling fan, hue bulbs/led strip in other parts of the office with full led lighting on the cpu case/mousepad/mouse so the idea is to synchronize them all via openhab for my “practice” project (may need an IOT wifi hub for it to connect without my phone present though even though it says no hub needed…my ass). I haven’t had a whole lot of time to work on it so it’s been slow-going but my god the possibilities are huge in it.
After that works out I want to make a more comprehensive layout that’s designed for an old tablet screen and only a tablet screen - essentially the endgame being most home automation and even a diagnostic screen for a grow room. I am bad at coding though so…who knows!

That was pretty much my exact reason for buying this one, and it was on clearance for like $25. I hate to admit how much I enjoy RGB LEDs, but I’d be lying if I said I didn’t have a big ass bag of them behind me that get used in various projects. I’ll have to check out openhab.

My office is like a fucking disco…I am a large child. Hell, I even got an audio EQ setup on the LED keyboard! Favorite thing i’ve done with it so far other than animate an LED heart monitor thingy across the keyboard!
I swear to god the majority of the reason i’ve been working so hard to make my car badass is so I’m not embarassed to put LEDs underneath it, haha

That’s like gold plating a hammer to me… I mean, I just don’t do things like that to my tools.

Smart Man right here!
one little project I have going right now is a Bluetooth speaker built into a bench. The speakers are car speakers I had lying around and are powered by a 12V car amp which I power with a meanwell 300watt psu. The brains is an rpi2. The pi hosts a rest api on my local network. I can send requests like turn on, turn off, volume up, next track, etc to the API, which is then making system calls to the rpi to launch a Linux app called random play that I actually use to play the music.
The nice thing about the rest api is it’s a backend interface that’s abstracted. All I need to do is send a proper http GET request to my api and it will do the rest. The rpi then also hosts a simple web page which has buttons on it that you can click which then send out requests to the api. Also I have built a hardware controller out of a rpi zero that sends requests using python but since I built the website , which I can load from my phone or any computer on my network, the hardware controller is a nonstarter. The webpage interface is much more flexible.
I’d suggest considering this type of implementation for your tablet interface.
Edited to add the API script and raw html page (nothing fancy). I run the API script as a cron job at reboot. Easter egg audio included

Oh shit, you’re a nerd too!!! I like it!!!
I’ve been slacking on my projects this week, i’ve been busting my ass cranking as much bubble as my lil` flippers can make but I have a feeling i’ll be getting soooooo many raw materials from friends and family for christmas that something will be coming soon!

It squeaks for them, but is silent for you. I think it’s brilliant.

Speaking of RGB leds, lasers are still technically still made with light emitting diodes, hella coherent collimated light. Ran out of hallway way too fast tho.
