Force FTDI FT232 USB to serial converters to use a single Windows COM port

Ever notice that each new FT232 inserted into each USB port is assigned a unique COM port number under Windows? When we’re developing hardware with lots of prototypes flying around Windows quickly hits COM 100. Each FT232 has a unique serial number and the driver creates a new COM port for each by default. FTDI […]

Ambulance drone, a flying toolbox containing emergency supplies for life support

The Ambulance Drone project- a flying defibrillator created by Alec Momont from Technical University of Delft, built as a Master thesis research project.  It aims to help save a life: The first minutes after an accident are critical and essential to provide the right care to prevent escalation. Speeding up emergency response can prevent deaths and accelerate recovery […]

Crystal oscillator frequencies

Drone refers us to this table of Crystal oscillator frequencies from Wikipedia: Wikipedia has a nice table of “Crystal oscillator frequencies”. The table includes a column of crystals divisible by powers of 2 which may be appropriate for Real Time Clock (RTC) references… Xtal frequencies covered in the table (at my post-time) cover 32768KHz through […]

8 and 16 bit computer system fonts

How many 8-bit and 16-bit computer system fonts do you remember?  These two articles look at who was behind them, and what gives early home computing such a distinct feel: My love of typography originated in the 80′s with the golden years of 8-bit home computing and their 8×8 pixel monospaced fonts on low-resolution displays. […]

9046xN random access write-only memory

MichaelZ tipped us to the 9046 x N Random Access, Write Only Memory: About 1974, Signetics bought a two-page, full-color spread in the April issue of ELECTRONICS Magazine, and published the WOM data sheet, as a (rather expensive) April Fool’s Joke. This version of the WOM data sheet shows the various features of Signetics’ Model […]

Return-to-zero engineering comic

Return-to-zero is a new comic strip for engineers: We bring to light the “Engineers World” with lab humor, exploding circuits, and of course making a sport out of solving the trickiest of engineering problems. We’re also big fans of xkcd, another long-running tech geek and engineering comic. Thanks Elaina! Via the contact form.

Seeed Studios’ electronic pet
