Here’s a little Ultrasonic Ranger using the Parallax brand Ping ultrasonic transducer pair and the Parallax LCD display. Both are easy to use with the Arduino system. Just don’t try to supply more than…
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
Converting A 5HP and 1HP 460V three Phase Milling machine to run on single phase 220V 30A Project Insanity Hacked that VFd! 😉 Recycle… Reuse… video of moving this beast here: Blessings. ~Russ http://rwgresearch.com/
I changed the code a little bit to show the resolution of the ultrasonic ranging method used by the Arduino/Ping combination. I think that the resolution is about 1-2 mm at the distance I…
I’m starting to develop a generalized driver for Pulse Motors using the Arduino OSEPP Uno clone. Here I’ve gotten the sensor input system programmed into the unit, and I show its function and serial…
Using PulseFire As a Arduino Controlled Voltage Data Logger (Demo) first of all, i want to than welliam for his hard work!!! == PulseFire == http://open-source-energy.org/forum/showthread.php?tid=440 www.rwgresearch.com RWGresearch
This little gadget is primarily for Joule Thief research, where the relative brightness of an LED must be compared or monitored as conditions change. The TSL235A is a small sensor that converts light intensity…
Patent No.:Â WO/2008/103129 Applicants: KAPANADZE, Tariel [GE/GE]; (GE). TURK, Metin [TR/TR]; (TR) (All Except US). Inventor: KAPANADZE, Tariel; (GE). Priority Data: 20.02.2007 Abstract: The independent energy device improved with this invention, starts operation with the…
The Parallax brand LCD display is easy to use with the Arduino. It only needs a single data pin on the Arduino, and 5 V and ground connections. You need the Parallax LCD library…
Here’s a small and easy inductance meter made from the Arduino and some other parts. Old TVs are a great source for capacitors, diodes, and even some chips: I found this handy dual lowvoltage…
