The concept of an outlet tester is pretty simple: plug the gadget into a suspect wall receptacle, and an array of LEDs light up in various patterns to alert the …read more Continue reading Mapping Out the LEDs on an Outlet Tester
Yep, this keyboard is another ebay special. I can’t stay away! This is a SafeType™ V801 from probably the early 2000s, although there is no date on it anywhere. I’m …read more Continue reading Inputs of Interest: SafeType™ Vertical Keyboard with Mirrors Puts Pain in the Rear-View
Today if you wanted a little gadget to sit on your shelf and let you play classic games from the early console era, you’d likely reach for the Raspberry Pi. With slick emulator front-ends like RetroPie and DIY kits available on Amazon, you don’t even need to be a technical …read more
The holidays are upon us, and that can mean many furrowed brows trying to figure out what token gift they can give out this year as stocking-stuffers. Something that’s a bit more interesting than a coupon book or a lotto scratcher, but also affordable enough that you can buy a …read more
We will all at some point have opened up a device to investigate its internal workings, and encountered a blob of resin on the PCB concealing an integrated circuit. It’s usually a cost thing, the manufacturer has sourced the chip as bare silicon rather than in encapsulated form, and it has been bonded to the board with its connections made directly using fine wires. The whole fragile component is then hidden by a protective layer of resin.
Normally these chips are off-limits to we experimenters because they can not be removed from the board without damage, and we have no …read more
