Fresh hacks every day
We've seen [Todd Harrison]'s work a few times before, but he's never involved his son so throughly before. This past Easter, he thought it would be a good idea for his son and a few of his friends to take part in an easter egg hunt. Being the ham he is, he decided to turn an easter egg hunt into an adventure in radio direction finding, or as amateur radio operators call it, a fox hunt. [Todd] … [Read more...]
When playing around with a cheap, handheld, dual-band radio, [Lior], a.k.a. [KK6BWA], found a schematic for a similar and even cheaper radio. He realized the programming pads were very accessible and the dev tools for the radio's microcontroller were available from the manufacturer. After these discoveries, there really was only one thing to do: write new firmware for a $40 radio, and making a … [Read more...]
Don't get us wrong, we love our Raspberry Pi. But if you're merely running a Linux image without adding a hardware hack into the mix you're missing out on part of the power for which the platform was developed. This project is a great example of how to embrace the Raspberry Pi's ability to deliver both low-level hardware access, and solid embedded Linux performance. [Dan Ankers] and [Threeme3] … [Read more...]
[Todd Harrison] really has our number. Like him, we don't want to spend money when we don't have to, and hacking our own solutions is a lot more fun anyway. This time around he's helping out a friend who is a ham radio enthusiast. The friend's radio didn't come with a frequency display, and buying the add-on would cost more than the radio did. So [Todd] has set out to build an Arduino frequency … [Read more...]
Looking for something to do this fine Saturday morning? For the US and Canadian readers out there, the fourth weekend in June is amateur radio field day, a day when all the amateur radio and ham geeks get together, string up a few antennas, and do their yearly community outreach/contact as many other radio heads as possible. This weekend, there are more than 1600 field day events taking place … [Read more...]
[Sebastian] is learning Morse code and CW radio, and of course he needed a telegraph key. Instead of using the terribly unergonomic paddle style key, he built a capacitive touch iambic key over the course of a few evenings. An iambic key usually has two switches. When one switch is closed, it will transmit a 'dit'. When the other switch is closed, it will transmit a 'dah'. Instead of using … [Read more...]
In the interests of interface archaeology, [Martin] sent in the Tworse Key, a telegraph key that posts to Twitter using Morse code. It's a fantastic build that nearly looks like something out of the 1900s. We've seen a ton of Morse keyboards over the years, but never one so well-engineered for a single purpose. The guts and brains of the Tworse Key is an Arduino Ethernet that connect to … [Read more...]
