In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting for an altogether simpler desktop fire control solution. This fun build uses a common off-the-shelf USB “missile launcher” that fires foam darts. To supply targeting data […]

Having a computer that locks its screen after a few minutes of inactivity is always a good idea from a security standpoint, especially in offices where there is a lot of foot traffic. Even the five- or ten-minute activity timers that are set on most workstations aren’t really perfect solutions. While ideally in these situations

[Aaed Musa] has built a variety of robots over the years, but found off-the-shelf servos to be underwhelming for his work. Thus, he set out to build a better actuator to support his goals of building a high-performance walking bot in future. [Aaed] decided to try and build a quasi-direct drive actuator, similar to those used in

When miniature LCD TVs arrived on the market they were an object of desire, far from the reach of tech-obsessed youngsters. Now in the age of smartphones they’re a historical curiosity, but with the onward march of technology you can have one for not a lot. [Taylor Galbraith] shows us how, with an ESP32 and an

We all might dream of having an industrial robot arm at our disposal, complete with working controller that doesn’t need constant maintenance and replacement parts, and which is able to help us with other projects with only a minimum of coding or instruction. That’s a pipe dream for most of us, as without a large

FPGAs are supremely flexible and powerful devices. However, they usually come in QFP or BGA packages that are altogether difficult for hobbyists to play with. The DIP-FPGA breakout board aims to solve that problem by using a carrier PCB to put an advanced chip in a friendlier form factor. The board itself fits a DIP-20 form
