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 […]

So if you are like this Lazy Old Geek, you have a lot of rechargeable batteries lying around. I wrote another Instructable with some battery tips. http://www.instructables.com/id/Rechargeable-Battery-Tips/ Amongst these batteries, I have a lot that no longer work or don’t work very well. So I decided to try to revive them. First step: If the

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

A Project by: ShuChuan Yao, Jeongwoo Jang, Zijie Tan Arduino Uno Servo Motors x4 fishing wires pins (cotton buds stem, thread rod, toothpick) Gyro Sensor 9V Battery Pretty Scarf/Bandanna Do you ever feel the need to express
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
The circuit presented here can automatically charge a 12V, 7Ah battery, or above. Special features of the charger are as follows. It automatically controls the charging current as per the status of the battery. Battery voltage level as well as charging status are indicated on the LCD display. The charger maintains float voltage, if battery
