The DIY Arduino Telescope GOTO control project

The DIY Arduino Telescope GOTO control project

Why make your own Arduino control system? After completing my homemade telescope mount it was powered by a Meade DS motor kit. This system was extremely slow, underpowered and unreliable. It was also impossible for me to change the programming or maintain the system. I decided to make my own telescope control system from the …

DIY wattmeter with an Arduino

DIY wattmeter with an Arduino

DIY wattmeter with an Arduino It is difficult or sometimes even impossible to measure power and energy with ordinary multimeters. To carry out such a measurement reliable and accurate, a special wattmeter is required. Because these meters are very expensive, a cheaper solution is presented here as a DIY wattmeter based on a Arduino Nano …

Let’s go creative with lighting on a DIY laser device

Last year MediaInteractiveDesign and PlayModes , two interactive design and creative technology studios based in Catalonia, collaborated to develop a system to control DIY Laser robot. They created a new shield  to control Dinamyxel servomotors  to work with PWM laser drivers. The shield works using Arduino Ethernet programmed with a specific firmware to control laser and motor using …

Air-Quality-Sensing

DIY Air Quality Sensing from HabitatMap and Sonoma Tech

High-precision air quality monitors are normally very expensive, but Tim Dye of Sonoma Technology is on a mission to change that.  He’s been working with Michael Heimbinder and habitatmap.org to create a low-cost sensor system that when designed properly and integrated into a software platforms can provide valid data. AirCasting is a platform for recording, mapping, …

Small form factor DIY Arduino on stripboard

Small form factor DIY Arduino on stripboard

This board needs FTDI cable to program it. It is not Arduino compatible in the meaning of taking shields (just like every small form factor board isn’t). But it has all the same pins (exept 3.3V power and Vin*) available as female headers. The input and output pins that are right next to each other …

DIY Larson Scanner

The KITT-duino, DIY Larson Scanner with an Arduino

IMPORTANT: CODE IS NOW UPDATED. FIXES INCLUDE ADDING AN INTEGER VALUE TO MANIPULATE TIMING AND FIXING A DOUBLE-BLINKING LED. Thanks. It is my understanding that many Larson Scanners can only pulse from side to side. I felt that that needed to be changed, seeing as that in the newer (yet short-lived) Knight Rider series revival …
