Collaborate Disseminate
[Michael Horne] recently shared his thoughts on the RedBoard+, a motor controller board for the Raspberry Pi aimed at robotic applications. His short version for busy people is: if you’re at all into robotics, get one because it’s fantastic.
At heart the RedBoard+ is a motor controller, but it’s …read more

If you’ve played even just a few minutes of Minecraft, you know what a creeper is. For those not familiar with the wildly popular sandbox game, a creeper is a monster that creeps along silently until it’s close to a player, whereupon it self-destructs by exploding. Sometimes it kills the player outright, and other times the explosion blows them into lava or off a cliff, or off a cliff and then into lava. Creepers have no friends.
But now there’s a way to avoid creeper attacks, or at least get a little heads up that these green nasties are lurking …read more

It’s sad, when you think about it: a retired railroad telegraph operator, who probably once pounded out code at 40 words per minute, with a collection of vintage sounders silently gathering dust on a shelf. [kthrace] decided to do something about that, and built this Morse sender to bring those old sounders back to life.
As archaic as Morse might seem, it’s a life skill, one the 92-year old former brass-pounder for whom this was built was eager to practice again. There are code practice oscillators, of course, but dits and dahs are no substitutes for the electromagnetic clicks and …read more
