Fresh hacks every day
Reader [Mikey Sklar] told us about a review he wrote covering 3 different models of pocket multimeters. We’re sure that you’ve had the same experiences we have being the go-to-guy or got-to-gal for all things electrical. For our sort, having a multimeter on hand at all times has become an expectation.
[Mikey] looks at a model from ebay, … Read the rest
Here’s another adafruit product launched today: a prototyping shield that compensates for the Arduino’s stupid oddly spaced headers.
Related: The Seeeduino has an alternate row of headers with protoboard friendly spacing.… Read the rest
adafruit industries’ latest product is an adjustable breadboard power supply kit. We’ve seen breadboard supplies before, but like most of adafruit’s kits, this is the best design you’re going to encounter. It uses an MIC2941 voltage regulator instead of the more commonplace LM317. It has a very low dropout which means your output voltage can be much closer to … Read the rest
Our friends over [adafruit] recently released the Sensor Pack 900, a collection of parts for anyone who is interested in using analog sensors with their projects. The pack includes 9 sensors. They range from simple thermistors and hall effect sensors to sharp distance sensors. Also included in the pack are 3 unidentified components that can be used to interface … Read the rest
[adafruit] wrote in to let us know that the Tweet-a-Watt is now available in kit form. While the plans have been available for a while, a kit is a welcomed addition. The kit doesn’t include the Kill-a-Watt monitor, but rather the XBee adapters and parts necessary to make it talk to your Arduino or computer. The kit is $90, … Read the rest
After seeing the xkcd comic where they call the Kindle2 the hitchhiker’s guide, [Ladyada] couldn’t help but laser etch the Kindle 2 with “Don’t Panic”. We think it looks pretty good, if a bit bubbly. You can see the video of the entire process after the break. Now that xkcd has infiltrated our interwebs, hearts, and minds, maybe he … Read the rest
[ladyada] has republished an interesting snippet from the synthDIY mailing list. [David Dixon] discusses the actual chemistry behind ferric chloride based home circuit board etching. He concludes that ferric chloride is essentially a ‘one-shot’ oxidant. It can’t be regenerated and can be difficult to dispose of properly. The use of acidified copper chloride is a much better path and … Read the rest
