Maybe it´s the right time for you to also consider usage of OLED displays in your applications.   The most advanced display technology – OLED, goes ahead into many industrial products thanks to its advantages. From a certain point of view exactly the industrial environment properly checks features of displays and especially in critical applications […]

This project explores the Adafruit PiTFT touchscreen and the Raspberry Pi camera board to create a simple point-and-shoot digital camera. One can optionally use WiFi and Dropbox (a cloud file storage and synchronization service) to automatically transfer photos to another computer for editing. This isn’t likely to replace your digital camera (or even phone-cam) anytime […]

Audible click, protection against backing out and disengagement together with many versions and attractive price – these are the Power Tripple Lock connectors. Universal connectors for interconnection of leads (wire-to-wire) as well as leads to a PCB (wire-to-board) are necessary every day and practically everywhere. In industrial applications we usually need various connectors. “Various” usually […]

Hey, It’s been along time since I’ve posted. but I’ve been keeping busy with uni and working on some cool projects for the last year.   This is something I’d like to share with you guys, it’s not finished yet but the hardware is more or less complete. It is an RGB LED ring clock. […]

Xeno Lithium batteries offer high capacity at extremely low self-discharge and are able to supply your device for many years. Primary Lithium batteries (Lithium thionyl-chloride, LiSOCl2) represent batteries with the highest energy density (Wh/kg), moreover able to operate without problems even in strong frosts. Perhaps their only technical “drawback” is the fact, that they´re only […]

The dB (decibel) is one of the most common units in engineering, yet also one of the most confusing, especially when it comes to manipulating S-parameters. Here is how not to be confused. The Bel is a fundamentally new unit, which was originally established in 1928 by The Bell System to describe sound levels. This […]

This servo controller generates a signals to control a standard servo motor (I used a Futaba servo but you can use any servo) using the 12F675 microcontroller.  You can type a text command into a serial terminal e.g Hyperterminal to set the position of the servo. The project software works slightly differently to the previous […]

What really drove me to build this 6EM7 amp was an idea about amplifier layout. Looking back at most of my tube designs, and most of those on the internet, revealed a very typical pattern. Amplifiers tended to be flat chassis with tubes and transformers above and electronics below. From a historical perspective this makes […]
