The Salad Days

I've got the idea to make an Arduino-based metronome while I was between other projects. It's got a Neopixel ring for flashing the beat (plus a piezo buzzer) and displaying the current BPM, plus a pair of buttons for increasing/decreasing the rate. So, pretty simple - but kind of cool. I still need to figure out an enclosure for it - I'll post another pic once it's done.

I've done some more work on the KSP control panel - I've connected up all of the button and switches on the first two panels, and have them talking to an Arduino Leonardo. The bottom pic shows the first custom PCB I've ever designed and had made. It's basically some shift registers and pull-downs to support 16 buttons/switches per PCB, will connections to allow chaining multiple copies together. It was a cool and pretty inexpensive experience - I think I might try to make more custom boards in the future. For example, a lot of my neopixel-based clock ideas are essentially the same circuit every time. I might try to design an Arduino Shield with that circuit on it, to make my designs cleaner and faster to build.

Sean and I play a video game called Kerbal Space Program, where you build things and send them to space - everything from simple orbiters, to space stations, to landers and rovers to other planets. What's cool about it is how it tries to keep things pretty realistic - you have to learn a bit about orbital mechanics in order to be successful, for example. One thing we noticed online is that some people build these elaborate control panels and connect them to their PC to play the game - lots of switches, LEDs, etc. - just like a real control panel. That sort of project is right up my alley! Sean and I have started working on one. We're still in the early stages, but I'll try to share some photos as we go.

Yup - another clock. :P This one reports the time in five minute increments, but uses words - as in, "it's half past three o'clock". It's not as blindingly-bright in person - my camera makes it look a lot brighter than it really is. For the case I used some awesome tiger maple that I've been hanging onto for a while. It doesn't come across in that dark photo, but in person it looks awesome!
