What kind of device is this? And what can you do with it? Well, this device doesn't need much explanation.
The most useless device in the world!
The Useless Box literally serves no purpose, but at the same time it's so hilarious that you'll want to show it to everyone. With this kit you have the opportunity to build your own Useless Box and expand your technical knowledge. Ultimately, this device switches off every time it is switched on and therefore performs a completely pointless function.
Still curious? Then watch the video below. A must-have for every office: at home or at work!
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
Pixy2 can be taught to detect objects by the press of a button. It is equipped with a new line detection algorithm to use on line-following robots. It can learn to recognize intersection and follow road signs.

Scientific Information
The Mendocino Motor AR O-8 is a magnetically levitated, solar powered electric motor as a kit.
Light Becomes Movement
The solar-powered Mendocino motor seems to float in the air. At first glance, you can't see why the rotor is turning at all. This is the magic of the motor.
The Lorentz force is a very small electrical force. In a classroom setting, it is detected by a current swing in the magnetic field. With the Mendocino motor, we have succeeded in developing a beautiful application that uses this weak force for propulsion. Due to its concealed base magnet, the motor will fascinate technically inclined observers.
In bright sunlight, the motor can reach a speed of up to 1,000 rpm. More impressive, however, is that even the faint glow of an ample tea light (D = 6 cm with a flame height of about 2 cm) is sufficient to drive the motor. The motor is not yet an alternative source of energy, even though it looks tempting. Presumably, it will remain an attractive model until a resourceful mind disproves this assumption.
Dimensions
All solar cells 65 x 20 mm
Mirror diameter: 25 mm
Rotor weight: approx. 150 g
Model length: 160 mm
Model width: 85 mm
Frame height: approx. 85 mm
Frame material: black acrylic
Tube made of highly polished aluminum
Mirror color: silver
The Mendocino motor’s easy-to-follow instruction manual includes more than 70 illustrations. It describes a safe and practical approach to construction but also gives you the freedom to try your solutions.
Partly Pre-Assembled Kit
A portion of the kit comes pre-assembled. Bonding the borosilicate glass pane to the acrylic surface requires specialized knowledge and aids. We do not want to impose this on the hobbyist. For instance, the base magnet is attached to the aluminum tube.
As a hobbyist, you will need some know-how and appropriate tools: carpet knife, soldering iron and tin, hot glue, pliers, and a clamp or ferrule to fix the supplied assembly aid. A lot of fun is guaranteed!
Raspberry Pi Pico is a great solution for servo control. With the hardware PIO, the Pico can control the servos by hardware, without usage of times/ interrupts, and limit the usage of the MCU. Driving the six servos on this robotic arm takes very little MCU capacity, so the MCU can deal with other tasks easily. This 6 DOF robotic arm is a handy tool for teaching and learning robotics and Pico usage. There are five MG996s (four are needed in the assembly and one for backup) and three 25-kg servos (two needed in the assembly and one for backup). Note that for the servos the angle ranges from 0° to 180°. All the servos need to be preset to 90° (with logic HIGH 1.5 ms duty) before the assembly to avoid servo damage during movement. This product includes all the necessary items needed to create a robotic arm based on Pico and Micropython.

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.
This is a kit for a pan-tilt mechanism explicitly designed for Pixy2. After assembling the kit and connecting it to Pixy2, you'll be able to follow colored objects using the Pan/Tilt demo.
It includes two laser-cut plastic pieces for the base, two different servos for the pan and tilt axes, and all the mounting hardware and cable ties you will need to assemble.
Features
The pan-tilt mechanism for Pixy2 is redesigned, making it smaller and faster than the pan-tilt for the original Pixy.
All necessary hardware is included.
The pan-tilt base is attached directly to an Arduino with Arduino-compatible hole-pattern and includes stand-offs and fasteners.
Several pan-tilt demos are provided that can run using either Arduino, Raspberry Pi or stand-alone (no controller).

This smart plinth lighting automatically switches on and off when you get up at night. The motion sensor sees you get out of bed and the light turns on! There is an illuminated path from bed to toilet. Obstacles on the way to the toilet are immediately visible and tripping hazards are prevented. Scientific research shows that the fear of falling is significantly reduced when using a Guide Light.
The LED lighting has a perfect light intensity. The light is subtle enough not to wake you up, but bright enough for a reliable orientation. The Guiding Light is much more than just a night light.
