Fresh hacks every day
[Andreas] wrote in to let us know about this DIY Neurophone project. Apparently a Flanagan Neurophone uses ultrasound in some manner to transmit audio directly to the body, or nervous system? Needless to say we are a bit skeptical of anyone whose wiki page leads directly to pyramid power. In fact most of the references to this thing start rambling about some pretty pseudo-scientific … [Read more...]
If you've ever needed a short-range remote control for a project, [firestorm] is here to help you out. He put up a great tutorial on using an IR remote to do just about anything with everyone's favorite microcontroller platform. [firestorm] used the Arduino IRremote library to decode the button presses on his remote. After uploading the IR receive demo included in the library, the Arduino … [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...]
Since Adafruit released a few dozen hacker skill badges, we've been waiting for this tip to come in. [phillip torrone] over at Adafruit posted a requirement sheet put together by a school teacher-blogger friend aimed at high school students wanting to earn their Hackaday skill badge. The requirement list is heavily influenced by the requirements needed to earn a merit badge in the Boy and … [Read more...]
In the last few months, software defined radio has seen an explosion in popularity thanks to a small USB TV tuner dongle able to receive anything broadcast between 64 and 1700 MHz. It's a very neat project that opens the door to a whole bunch of radio experimentations, but getting started in the SDR world can be a bit daunting. To help everyone out, [MS3FGX] is writing a getting started guide so … [Read more...]
A few months ago, we saw a hack where a $20 USB TV tuner was transformed into a software-defined radio capable of reading GPS signals, listening to radio transmissions between aircraft and a control tower, and even a simple FM radio. This project is a perfect introduction to the RTL-SDR and Ham radio scene, but getting these projects up and running can be a bit overwhelming for anyone who hasn't … [Read more...]
There comes a time in every maker's career where solderless breadboards won't do, perfboard becomes annoying, and deadbug is impossible. The solution is to manufacture a PCB, but there's a learning curve. After learning a few tricks from [Scott]'s awesome DIY PCB guide, it's easy to make your own printed circuit boards. There are a few basic steps to making a PCB. First is designing the board … [Read more...]
