Vishay Automotive-Grade Low-Profile High-Current Inductor up to 180°C
Posted on: 21 Jul 2016
Vishay Intertechnology introduced a new automotive-grade IHLP® low-profile, high-current inductor with an industry-high continuous operating temperature range to +180°C. Offered in the 2525 case size with a low profile of 3.0 mm, the new Vishay Dale IHLP-2525CZ-8A provides a wide range of inductance values from 0.47 µH to 22 µH. With a frequency range up […]
Arduino controlled light dimmer
Posted on: 20 Jul 2016
WARNING: Some people try to build this with an optocoupler with zerocrossing coz ‘that is better’ right? Some are even told in electronics shops it is better to use such an optocoupler. WRONG. This will only work with a random fire optocoupler: NOT igniting at zerocrossing is the principle of this dimmer. Switching an AC […]

Project curve tracer – progress update
Posted on: 20 Jul 2016
As the hardware is at the point of initial release, but the firmware and GUI aren’t quite there yet, I decided that it would be prudent to split off the firmware and GUI components into their own GIT repositories. Tracking all files in the same repository was convenient through the initial stages of project development, […]

Posted on: 20 Jul 2016
MEC push-buttons can be found even in the dark All about brand MEC EC switches can be seen even from afar Switches MEC Unimec switch in up to eight ways Illuminated push-buttons represent a universal solution into every environment. An answer to a question, whether it´s nicer to use a push-button with a backlight or […]
Cheap Easy Solar Powered Robot
Posted on: 19 Jul 2016
Make a very cheap, relatively easy to construct robot which will wake up any time you shine a desk lamp on it. There are no sensors on it, although I suppose the solar panel can be called a sensor. I plan on adding solar panels and another motor, and making it controlled by a PIC […]

Designing a Mains Frequency Monitor, Part 2 This is the second in a series of posts about designing a mains frequency monitor using the Microchip PIC 16F1619 microcontroller. In this post we will take a look at the first revision of the board that I designed for the project and some of the features that […]
RC5/RC6 codes on a LCD using PIC16F648A
Posted on: 19 Jul 2016
A simple project to test and display the transmitted codes from remote controls which work with the RC5 protocol, like the TV remotes from Philips, just aim the remote control at the TSOP1736 IR-receiver. If you only want to know the code from a button then you can ofcourse also look at the RC5 tables […]
