pinko @ blog.exrockets.com wanted to regulate the power to a resistive load so he decided to build a PWM power regulator based on PIC18LF2550. In order to synthesize chlorates and perchlorates in the home lab it is always good to have a way to regulate the current flowing through the...

"limpkin" @ limpkin.fr wanted to program some thousand of MCUs so he decided to build his own programming bench. He writes: As you may know I started the Mooltipass offline password keeper project more than 2 years ago. Together with a team of volunteers from all over the globe I...

Tibbo has a new list of tutorials on their website. Check them out: Quick jump to start NodeJS development on LTPS boards http://tibbo.com/linux/nodejs/before-you-begin.html LED Control From the Web Browser http://tibbo.com/linux/nodejs/led-control-from-browser.html Two-way...

pinko @ blog.exrockets.com has build a GPS receiver to FM radio based on PIC18LF2553. He writes: Today I made some modifications to this is a new project for a GPS to FM radio tracking device for rockets i.e. the V2. The initial design lacked the antenna impedance matching circuit...

One of the most harmful airborne pollutants with respect to human health is particulate matter. Air particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a...

The project specifically designed for motor speed control application in appliances such as blenders, etc. Tact switches provided for selecting/indicating from 1 to 10 power levels ( Speed Levels).  The project is ideal for universal and shaded-pole motor speed control for...

A lot of project are battery powered and some of them need dual battery links. Robert on hackaday.io had shared his new project that shed light on this issue. He built an load sharing addon board with the ability to charge the battery while the project is operating. Many Chinese...

Arsenijs build a Pi-powered open-source mobile phone (that you can assemble for 50$ in parts). Currently, it costs about 50$ in parts, and all the parts are available on eBay. No BGA or other difficultly solderable ICs are used (with the obvious exception of Pi Zero). User interface...
