[Etienne Sellan] got one of these lovely $5 logic analyzers. As with any shiny new tool, he started looking for things to investigate with it, and his gaze fell on a Sentry Safe (produced by Master Lock). On the surface level, this keypad-equipped safe is designed decently when it comes to privilege separation. You can take the […]

With this ‘Test Fixture’ and provided software you can test virtually any MCU with as little as 4 digital I/O lines (even only 2 is possible, all be it tricky) for project suitability and performance. When I start a new project I don’t like hooking up a lot of wires before making any progress on

Most of us who work with electronics know the name of Texas Instruments (TI) as a manufacturer of several important digital and analogue ICs as well as fancy sophisticated scientific calculators. However many people don’t know that TI is also a manufacturer of some of industry’s best microcontrollers. TI’s portfolio of micros is pretty large.

Here we have a good example of how a requirement for a simple tool spirals out of control and spawns a project that takes months to complete and ends up dwarfing the project that it was originally expected to facilitate. You see, some time ago I was fiddling around with a project, something to do

Background. This project started out as an accessory for another planned KickStarter project – a smart TFT display for Arduino called CleO. Now, the display itself required 150mA current, fine, but when you add a camera with its LED lights, this goes up to 250mA and if you have 1W audio playing simultaneously, unlikely,but possible,
