Battery Eliminator

Do you have an appliance that eats through batteries? Follow this instructable for a simple, quick and dirty trick to power it directly from an outlet! If you want to do something more thorough, check out doncrush’s Battery Eliminator from a recycled wall wart. I will focus on replacing a single D battery, used in […]

Arduino Temperature-Controlled Fan

I and a few group members have decided that, for the summer, it would be beneficial to create a fan that turns on at 70 degrees Fahrenheit and continues to increase in intensity with the heat. So that’s what we did. Gears First, we laser cut our gears. We have a 1:2 motor-shaft ratio with […]

Drone with dynamic tilt arms

I started this project from at summer 2015. Idea was create drone with moving arm feature. Frame is build from carbonfiber plates, aluminium standoffs, and 3D prints. Arm are 16mm carbon tubes. I didnt want to use any special, expensive or rare materials or components, so every component can be foun…By: -SV- Continue Reading » […]

Broken RC Vehicle Diagnosis: How to fix an RC vehicle

Hey guys! We all know that time when you’re playing with your remote control vehicle and it breaks. Heartbreaking, right? (See my pun?) Well, this is the Instructable for you. It’s simply a basic universal troubleshooting manual for common RC problems based on my experience. Alright then, let’s get started! Step 1: RC Cars Alright, […]

Arduplane – Arduino based rc aircraft

The design of rc aeroplane needs knowledge of aerodynamics and simple mechanics. For this I would recommend books such as Flight without Formula and Model aircraft aerodynamics by Martin simons. But for beginners it would be difficult to design using all parameters so I would recommend the website called www.flitetest.com . This has a lot […]

Build your own Raspberry Pi-powered smartphone #piday #raspberrypi @Raspberry_Pi

May 27, 2016 AT 3:00 am Build your own Raspberry Pi-powered smartphone #piday #raspberrypi @Raspberry_Pi Via Wired David Hunt is an Irish programmer, photographer and maker who loves tinkering with Raspberry Pi. He started thinking about building a Raspberry Pi-based smartphone when he came across a DIY “digital camera” prototype that combined the modifiable microcomputer […]

How to use the Soil Hygrometer Module – Arduino Tutorial

In this tutorial we will use one soil hygrometer module to measure soil moisture of a pot. The module can give us a digital signal when the soil need watering and this output can be adjusted by the potentiometer. Or it can give us an analog signal of current soil moisture! In this tutorial we […]

Ideal For Educators: Monthly 3D Printing Projects?

UK-based Laykanics is an interesting service that offers monthly 3D print-based project kits that I think could be very suitable for educators looking to expose students to 3D printing. The kits are composed of electronics and other non-3D printed items that are used to complete the project, as well as the 3D models you’d use […]

How to Use Water Flow Sensor – Arduino Tutorial

In this tutorial you will learn how to use one water flow sensor with an Arduino board.The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The […]

Biplane 10-300S

I have designed this plane from scratch using the software Catia. This plane was specificly designed for 3D printing, which means that it is very light (about 400 grams without electronics). There are .stl files of every part that is used on this plane (except the wooden beams – you have to buy them). To […]
