The TV-B-Gone universal remote control allows you to turn virtually any TV On or OFF. You control when you see TV, rather than what you see. The TV-B-Gone Keychain remote is so small that it easily fits in your pocket so that you have it handy whenever you need it, wherever you go: bars, restaurants, laundromats, ballparks, arenas, etc.The TV-B-Gone Kit is a great way to teach about electronics. When soldered together, it allows you to turn off almost any television within 150 feet or more. It works on over 230 total power codes – 115 American/Asian and another 115 European codes. You can select which zone you want during kit assembly.This is an unassembled kit which means that soldering and assembly is required – but it’s very easy and a great introduction to soldering in general.This kit makes the popular TV-B-Gone remote more fun because you created it yourself with some basic soldering and assembly! Show your friends and family how technologically savvy you are, and entertain them with the power of the TV-B-Gone!The kit is powered by 2x AA batteries and the output comes from 2x narrow beam IR LEDs and 2x wide-beam IR LEDs.IncludedAll required parts/componentsRequiredTools, soldering iron, and batteriesDownloadsGitHub

The Elektor Laser Head transforms the Elektor Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam! The kit includes all the necessary components, but soldering three wires is required. Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

Raspberry Pi-based Eye Catcher A standard sand clock just shows how time passes. In contrast, this Raspberry Pi Pico-controlled sand clock shows the exact time by “engraving” the four digits for hour and minute into the layer of sand. After an adjustable time the sand is flattened out by two vibration motors and everything begins all over again. At the heart of the sand clock are two servo motors driving a writing pen through a pantograph mechanism. A third servo motor lifts the pen up and down. The sand container is equipped with two vibration motors to flatten the sand. The electronic part of the sand clock consists of a Raspberry Pi Pico and an RTC/driver board with a real-time clock, plus driver circuits for the servo motors. A detailed construction manual is available for downloading. Features Dimensions: 135 x 110 x 80 mm Build time: approx. 1.5 to 2 hours Included 3x Precut acrylic sheets with all mechanical parts 3x Mini servo motors 2x Vibration motors 1x Raspberry Pi Pico 1x RTC/driver board with assembled parts Nuts, bolts, spacers, and wires for the assembly Fine-grained white sand
