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).
David Robinson used the data from the 28,657 people who self-selected to take the Stack Overflow survey to investigate the relationship between programmer pay and the conventions of using either tabs or spaces to mark indents, and found a persistent, significant correlation between using spaces and bringing home higher pay.
It’s the end of an era, sort of: Fraunhofer IIS, the developers of the MP3 audio compression format, announced that they are ceasing their licensing program. In a blog post, spokesman Matthias Rose says that it’s had a good 20-year run and is obsolete. But it’s also true that the decoding patents expired last year, […]
Freddy deBoer writes that he’s been telling the same joke for years about Silicon Valley’s only product, which might be universalized as “At last, a way to verb with nouns on the internet!” But the social-media techopoly is stable, now, and so the venture capitalists have moved on to the three terrible trends that will […]
Although flagship smartphones are unlikely to adopt heavy-duty outer casing anytime soon, you can always prepare your device for the outdoors with a beefy case and and an external battery like this Nomad Tile Trackable PowerPack, available in the Boing Boing Store for $119.95.The Nomad Tile can fully recharge an iPhone 7 over three times […]
Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
