“The CircuitPlayground and CircuitPlayground Express are great boards for learning with. This is largely due to the abundance of sensors and actuators built into the design. While there is a pile of builtin hardware, it doesn’t include everything. Fortunately …
“1.Since I was a child, I’ve always had a great admiration for electronics, I’ve always been struck by the fact of making things by myself, that’s why, today I bring you my first Instructable, I clarify …
“In this instructable Im going to show you how to make your own temperature and humidity monitor for your living room. The device also features WiFi capabilities, for the purpose of logging the data on a remote server (e.g …
“This is a small size power supply based on OPA549 power op-amp that provides output voltage 1.2V to 25V with 0 to 10A adjustable current limit. Two onboard trimmer potentiometers provided to adjust the voltage and current, LED D1 …
“This arduino mini CNC or XY plotter can write and make designs within the range of 40x40mm. Yes this range is short, but its a good start to jump into the arduino world. [I’ve given everything in this project …
“Mini CNC plotter machine with 3D printed frame. I have made a micro size CNC plotter machine out of old scrap DVD drive stepper mechanism The best part of this machine is i 3D print its frame to give it …
“Just 50 candle flicker LEDs powered by 3 AA batteries Forward voltage drop across the LED is 2.0-2.2V, so I decided to connect them in parallel, and to use step-down DC-DC, which converts 3.0-4.5V from …
“Building a “semi-directional” radiation and cosmic-ray detector is not an easy feat. I aimed to design, construct, and test a portable and versatile Silicon photo-diode Radiation Detector suitable for the 5keV-10MeV detection range to accurately quantify low energy gamma-rays emanating …
“My dad constantly whines about how annoying it is when commercials are considerably louder than their accompanying program. Since his complaining was becoming more annoying than the actual commercials, I decided to create a little gadget that would solve both …
“LED filaments are thin, stick like LEDs. They are used in many Edison bulb look-a-like LED bulbs.Each of those thin sticks contain many - 20 to 30 LEDs connected in series. So they are quite bright and energy efficient, however …
