This project is about making portable luxmeter. It can be used in schools, where children can measure different kinds of light sources.Functions: 1. measure intensity of light in lux. 2. calculate solar irradiation from lux to watts/m2 (factor 112) 3. charging battery using USB port Total cost is around 13 $ without case. Luxmeter take 15 mA, so […]

BotTender, a bartender assistant that pours the perfect shot! BotTender is an autonomous robot that is designed with the aim of automatising bars. It is placed on top of the bar and detects the shot glasses in front of it. Once the glasses are detected, it approaches to the glass and asks for the customers
I wanted to create a digital version of the Magic 8 Ball… The body of this is 3D printed and the display has been changed from an polyhedron in blue dye to a small OLED controlled by a random number generator programmed into an Arduino NANO. Then I went on a bit of a tangent

What is a picoballoon and why would I want to build it?! I hear you ask. Let me explain. You all probably know what a HAB (High Altitude Balloon) is. It’s a bunch of weird electronics stuff connected to a balloon. There are soooo many tutorials regarding HABs here on Instructables. BUT, and that’s a very big BUT what

When it comes to building the battery packs, Li-ion cells are one of the best choices without the doubt. But if you get them from old laptop batteries then you might want to do a capacity test before building the battery pack. So today I will show you how to make a Li-ion capacity tester

The inspiration for this instructable is the DIY Digital Spirit Level found here by GreatScottLab. I liked this design, but wanted a bigger display with a more graphical interface. I also wanted better mounting options for the electronics in the case. Ultimately, I used this project to improve on my 3D design skills (using Fusion 360) and to

It’s been a while since I’ve published my last Instructables. I’m back, and I’m 3D-printed-powered! Enjoy this mini retro arcade machine. It’s literally my first complete end-to-end 3D-printed project: I made the design, printed it, assembled the electronics, programmed it, and now to the tutorial 🙂 This guide will be updated soon with instructions to
