Fresh hacks every day
This artificial horizon might as well have come from an alien ship. [Mike] somehow manages to get his hands on most interesting equipment, this time its a very old piece of avionics equipment. The mechanical gyroscope functioned as the artificial horizon, and he's going to take us inside for a look. He doesn't spend quite as much time on it as he did that thermal imaging camera, but this … [Read more...]
At first glance you would think this is the real thing, but [Kevin] built this railroad crossing signal from parts you can find at the home store. We keep seeing traffic lights used as web-connected signaling devices. This would be right at home for that type of setup, but [Kevin] built it with railroad enthusiasts in mind. He used Google SketchUp to design the frame for the signal, then … [Read more...]
[Furrteck] had a little adventure with this FM transmitter he picked up on eBay. It worked alright, but he wanted to be able to scan through the frequencies, and to have the device return to the same settings after power cycling. He cracked it open and got to work to achieve all of his goals. The device is driven by an ATmega48, and there's a 6-pin ISP header on the board. An initial read of … [Read more...]
Travel backpacks are so passé. All the cool kids, like [Niklas Roy] are using scooter trunks for easy travel. Think of it, not only does it remove the need to carry your heavy baggage, but you get to coast along for the ride as well. We wonder what the officials at air, train, and bus travel hubs are going to think? The idea came from seeing a similar build with a flight case (plywood box … [Read more...]
Pretty early in development of my Ping Pong Clock I came up with the idea of automatic Daylight Saving Time compensation. It's an interesting feature, but it's a luxury and so I figured I could add it as a future improvement. Now's the time and I'm reporting back on what I've learned and how you can add this to your own projects. There's two things to think about before adding this feature. Is … [Read more...]
This clock looks fantastic because of the glass PCB used for the build. This banner image allows you to see all the traces and components, but when it is lifted off of the desk surface the LEDs which make up the 7-segment digits appear to be floating. The concept isn't new, but it's a much larger format than we've seen before. When we first looked at [CNLohr's] glass PCB fabrication he was … [Read more...]
LVL1 has a new rocketeering group. This rocket engine testing platform is the first project to come out of the fledgling club. The purpose of the tool is to gather empirical data from model rocket engines. Having reliable numbers on thrust over time will allow the team to get their designs right before the physical build even starts. The rig uses a pine base, with a PVC frame, threaded bolts, … [Read more...]
