This is a project that I’ve been working on for some time now, a good part of my life, but more recently for the past month. I’m not going to go through everything as to how I arrived at this point, but I can assure you it was through a lot of trial and error. […]

With the B&W Zeppelin Air being such a popular iPod docking station as well as a fantastic AirPlay compatible device we thought it would be a good idea to write a ‘how to’ on setting up your new Zeppelin Air. As of September 2012 newer machines are installed with a slightly newer firmware version. The […]

The LEDs (Light Emitting Diode) are diodes whose basic characteristic is the ability to emit light when they are passed through a current that flows from P to N region. At each recombination between the charge carriers (electrons and holes), on PN junction region, a photo emission is generated, and the total quantity of emitted […]

TI’s PMP9476 is a non-synchronous buck converter plus a non-sync boost controller accepting an input voltage of 3.5V to 40V, with 5V output at up to 3A of current to the load. It features a small form factor; with PFET to replace LM3481 controller rectifier to improve efficiency and low component temperature rise; and reverse […]

The Development Board v. 1.1 connected to an LCD display. It is well visible (read further, in the description) the row of LEDs used to check the logic state of up to 8 I/O ports or external circuits’ pins. Of course, if you own an 8 trace oscilloscope, you can do without it. :-)) On […]

An elderly, but still sought after Marantz CD63SE was bought into the shop last week, with the fault reported that CD’s would no longer play. After approximately 15 years of use, this is a common situation, as the laser power will gradually reduce over time to the point where it can no longer focus reliably […]

Should you however be afraid of accidental fall off of the connector (it will certainly hold on if there are no vibrations, shocks or unpredictable tension to leads), then for your peace of mind we recommend you to use connectors that can be secured by a screw. Naturally, devices exposed to vibrations are much more […]

Introduction This page is about electronic drums. Here you will find detailed information on how to build an electronic Trigger to MIDI Converter module, based on PIC Microcontroller, and how to build the triggers. This project has been developed for many years now, and it is constantly improving. You can expect professional results form your […]

New microcontroller enables enhanced communication security and supports standard encryption protocols Toshiba Electronics Europe has announced a new ARM® Cortex®-M4F based microcontroller for use in secure systems control. The TMPM46BF10FG expands Toshiba’s existing TX04 range and adds a selection of enhanced security features, ideally suited to applications in Internet of Things (IoT) devices, energy management […]

This 2004 vintage Arcam CD73 came into us with the reported fault that it would no longer play CD’s, or even read the table of contents. Given that it is over eight years old and had plenty of use in that time, we were not surprised to find that the laser had expired and needed […]
