WarningThe Rancilio Silvia machine runs on high voltage. Any modification to it might be fatal to you or your machine, you act at your own risk and responsible for your modification. Any modification to the machine might void the manufacturer warranty. Make sure to disconnect the machine from the power line before working on it. […]

So I have yet again over-engineered a task, this time, a freeze-dried coffee dispenser. Why you ask, well the obvious first, it’s super fun and second, it’s the best way to learn new skills. I’m a real noob when it comes to the inner workings of microcontrollers but I really want to know how I […]

Our new home has an interior 700L water tank with an electric pump supplying pressure to the house. Unfortunately, at times of peak demand, the external water supply pressure can drop so that the water tank is not refilling. This usually happens on a Sunday when we are in the middle of weekly laundry, car […]

Olá, em seguida, mostrarei como criar um jogo magnético de Plinko com Makey Makey. O título do projeto foi estendido para ser auto-explicativo: um jogo no estilo Plinko, que usa sensores magnéticos, ímãs e Makey Makey. Para a construção do painel, fui inspirado por este projeto: https: //www.instructables.com/id/Laser-Cut-Plinko … Também usei o corte a laser como […]

As a second year STEM teacher, I’ve been using the Makey Makey kits with my 4th, 5th, and 6th graders to explore circuitry, electricity, and to just have some fun! Students have had their choice of projects, ranging from interactive displays to musical instruments using Makey Makey and Scratch, and have truly enjoyed applying the […]

Hey fellow DIY’ers. Have you ever found your house door open after returning from a long trip? Me neither. But it is always good to have a safety system in our houses. I’m not talking about the old school projects like a laser trip wire, no no, that’s boring. This is something from the future. […]

This Instructable can be modified for any major holiday, however my students wanted to focus on something they could do for Valentine’s Day. In this design, students’ hands are the conductive material that complete the circuit when they “high-five” the two halves of the heart. When the circuit is complete, the “space” input triggers a […]

This Instructable will show you how to use a WaveShare motor/servo board with a micro:bit to power multiple servo motors. This board will make it possible to run more powerful servo motors than the micro servo motor that you can run directly from the micro:bit. Technical information for the WaveShare board is here: https://www.waveshare.com/wiki/Motor_Driver_for_mi… There is […]
