Kids just aren’t huge fans of brushing their teeth. Not only are they not huge fans, they also are pretty bad at it. Teaching a young kid to brush their teeth is really hard. I created a little contraption that not only times them to make sure they brush for an entire two minutes, but […]
It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them.
In this project, we will be making a weather station that measures air pressure, temperature, rain drop, soil humidity and air humidity using Arduino which save the data for data acquisition! It’s a fairly easy project and can be used either on its own or part of something bigger, check it out >> Integrated Weather
Automation is defined as using various control systems to operate equipment such that there is minimal human intervention. Closed control loops (feedback systems) regulate how other systems or devices behave by taking into consideration their output and making corrections based on feedback. An example of this feedback system is Progressive Automation Linear Actuators. In this

Voltage references are a humble piece of hardware, their sole function is to provide a stable, known voltage. This constant, known value of voltage can then be used as a reference for ADCs and DACs as well as provide a precision current source. I recently got hold of an Analog Devices AD587KN high precision 10.000V
This tiny Unipolar stepper motor driver has been designed around SLA7078MPR IC from Sanken, It is unipolar stepper Motor driver can handle current up to 3 Amps, micro-stepping up to 1/16 steps. On-board Jumpers to set the Micro-stepping, Preset (Potentiometer) to set the current. The SLA7070MPR series motor driver ICs features unipolar drivers. The clock-in
This project lets you measure capacitors in an alone range of measure from 0.000pF to 1000uF. That is, a 16×2 LCD Display will be displaying a sole scale from 0.000pF to 1000uF whose main components will be an Arduino Uno and a 16X2 LCD Display. Step 1: List of Materials 1 16X2 PARALLEL LCD DISPLAY
Summary This is a motorized solder paste dispenser for soldering SMT boards that was inspired by this thing http://www.thingiverse.com/thing:384680. The home directory of this project is on github here https://github.com/zapta/misc/tree/master/paste_injector and it include hardware and firmware design of a compatible controller board that is Arduino compatible (it looks to the Arduino IDE as an Arduino

This USB sound card that presents itself as C-Media is one of the cheapest sound cards available with price $1.1-$2 depending on vendor. Device markings: HX2010-0705, production date 40th week of 2013 (or later?). Device enumerates as composite device: sound card + HID input. HID input part is used for audio volume and mute control
Choosing $1 sound card for DC-capable low speed oscilloscope Continue Reading
Meet Makerarm As makers, we have ideas all the time––to improve things, to make our lives better. But to make our ideas happen, we need access to tons of machines, materials, and tools that are too expensive. That’s why we created Makerarm: a complete digital fabrication system packed into an affordable robotic arm that makes
