IEEE Spectrum put together a solid "DIY Essentials" list for a hardware/electronics workbench. From IEEE Spectrum:
Most of us start out using batteries or cannibalizing power adapters, but a good bench Power Supply lets you control voltages precisely as well as measure and limit the amperage flowing through the circuit. You can get a reasonable single-voltage supply for $120 or so, such as the 18-volt, 3-ampere supply made by Extech Instruments. More advanced ones will offer multiple controllable voltages, useful when projects have more than one input voltage.
A bench supply goes well with a large Protoboard, one that supports multiple supply voltages and has lots of real estate to lay out chips. If you do a quick proof of concept on a protoboard first, you can save yourself a lot of grief when you try to set out a permanent version (or send it out to a printed-circuit-board fab).
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
The office I work in is full of things old people buy to make themselves feel young again. I can honestly say that our awesome new toy, The Swagtron T3 Hoverboard, makes me feel very, very old. I’ll explain why later. Swagtron T3 Pros There’s no way to overcharge the battery and that means no […]
DJI is the world’s leading designer and producer of easy-to-fly drones and aerial photography systems. If you’re a drone enthusiast, you want a DJI. If you know absolutely nothing about drones and think they’re weird, if you win a DJI you’re going to become a drone enthusiast.Enter this giveaway (for free, yes) and you’ll get a […]
Although there will never be a consensus about the best way to make coffee, any coffee connoisseur will agree that controlling the grind of your beans and balancing water temperature are the keys to a tasty cup. Since your plastic coffee pot doesn’t really allow for that kind of customization, going back to the French […]
