Description Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to air hockey and juggling robots use them. However in industrial automation, brushless servomotors have taken over, and it’s […]
Pretty much. I was born in the nineties, and the first personal computer my family bought (a $3000 screamer with a 300 MHz Pentium II, 256 MB of RAM, and the optional Boston Acoustics speaker system) ran Windows 95. Also, this isn’t the first time I’ve installed an old operating system on a watch. Here’s
In this instructable, I will take you along on my journey of building this WiFi Outlet. Step 1: Parts The final box will contain: ESP8266 (any version will do) 5V Relay Module AMS1117 Low Drop Out Regulator 1K Resistor Duplex Outlet Wall Box Wall Plate Cellphone Charger (5V output) Power Cord Only needed while programming
The new Type-C USB connector is the latest addition to the USB connector standards. It offers reversible plugs, direction independent cables, USB3.1 speeds, and 3A charging in a connector only a little bigger than the USB 2.0 MicroB connector. In order to add these capabilities the plugs and connectors have additional configuration pins to allow
Description The small 2 Channel amplifier constructed around Sanyos LA4445 IC delivers 5.5Watts +5.5 Watts at 4 ohm load, supply in 12V DC 2Amp, Input impedance 30K. Specifications Dual Channels output : 5.5W Minimum External Parts Very small pop noise at the time of power supply ON/OFF Good ripple rejections Small residual noise Built-in protectors
From the minds at http://arduinotronics.blogspot.com/ Important Update! Since so many people were having problems with the INA125P, we now have a new and improved version that uses the Hx711 24bit ADC amplifier module. http://arduinotronics.blogspot.com/2015/06/arduino-hx711-digital-scale.html My goal was to create a programmable scale for weighing objects, parts counting, even directing product flow on a conveyor system.
You can download our e-book ‘Learn Arduino from Scratch’ from this link Few weeks ago I heard my nephew (aged 7) complaining of the dark at night. Basically he was afraid ? So I decided to put knowledge into practice and build a night lamp for kids. Since the project was intended for kids, I
Exactly 30 years ago a great disaster struck the region of Chernobyl: a nuclear accident occurred that released a large quantity of radioactive particles into the atmosphere. And it is only five years ago that, with the Fukushima Daiichi nuclear disaster, a second similar catastrophic event has taken place. These anniversaries did not directly let me build a PIN Photodiode based Geiger Counter,
Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL), is becoming more common as the next generation lighting. Evaluations of total luminous flux (a performance index for lighting) and color are important for SSL, and to

I wanted a simple way of quickly logging on to my computer without having to typing my password in and did not want to have no security either. There are various products on the market that would solve this problem from fingerprint readers to proximity dongles but I decided to see what I could knock
