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

Want to build your own weather station? This sensor kit has a cup anemometer and wind vane to measure wind speed and direction and a tipping bucket style rain gauge, together with associated mounting hardware. The sensors in this kit are active mechanical sensors that work by physically interacting with the wind and rain. They use magnets, reed switches and moving parts to produce simple signals that a microcontroller or single board computer can use to calculate wind speed, wind direction and rainfall. The sensor cables are terminated in RJ11 connectors (each sensor only uses two wires though, so if you wanted you could snip off the ends and connect the wires to a different kind of connector). Armatures to mount the sensors are included, as well as a short metal mast that can be lashed to the top of a suitable pole with the included jubilee connectors. Please note that this kit contains the mechanical wind and rain sensors only, and doesn't include any electronic components. You can hook these sensors up to the Pimoroni Weather HAT for Raspberry Pi. Included Wind vane Anemometer (wind speed gauge) Rain gauge Short metal mast (made of two metal poles that slot together) Two plastic arms for mounting the sensors Mounting hardware: jubilee clips, nuts, bolts and cable ties Documentation Getting Started with Weather HAT Comprehensive guide Datasheet
