A while back I got an SSD drive with the question whether it could be repaired. At first glance it looked fine. But wait… the PCB is not level. In fact, it is seriously wobbly. What on earth happened to this SSD? Looking closer at the flash ICs, it turns
When buying some GP branded NiMH rechargeable batteries about a year ago, a “GP PowerBank Travel” charger (model GPPB03GS) was included as a promotion. It’s a nice little charger that runs both off 220 V and 12 V (for use in car, I presume). It can charge 1-4
Got a new toy the other day… After using the same ERSA MS 6000 soldering station for the past 20 (!) years or so, it was time to upgrade. Nothing wrong with the old one really, except that it was hard to get new tips and that heating it up took
Well – given current exchange rate, AU 2.59 = USD 2.33.. So it’s not quite a two dollar product, but pretty close. And “2.33 dollar fan controller” did not make for a nice subject line… After the earlier post about variable 12V fan controllers, it might be worth
Comparing Fritzing, circuits.io and Eagle in a real-life design scenario.
Let's take a look at how low-cost fan controllers work. Can they even be built from parts in the junk drawer? Sure, no problem!
I recently got the chance to evaluate the Anaren AIR CC2530 BoosterPack Kit, which is a ZigBee eval platform for TI’s LaunchPad products, i.e MSP430 and Stellaris. Kudos to the good folks at element14 for providing the kit as part of their RoadTest program. The review is found
One of the first tools I built myself many, many (decades!) years ago was a logic probe. At the time things like yellow LEDs were still a bit rare and cool, but this baby had both red, yellow and green LEDs to indicate TTL logic levels. It was a true
A severely cracked 13″ Macbook Air display came my way some time back. The LCD panel was obviously damaged, but it would be interesting to see what makes such a great display tick, and maybe parts of it could still be used? I believe the display came from a Late
A while back I got a free PCB from Dangerous Prototype’s Free PCB program. It’s a nice little board designed to provide easy current monitoring during prototype stages of a project. Features include over-current tripping with visual indication, as well as dual 5V and 3.3V supplies.
