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).
The Cobham catalog, exposed by The Intercept, features countless pages of surveillance gadgets sold to U.S. police to spy on American citizens: tiny black boxes with a big interest in you. In the creepily bland feature lists and nerdy product names is a whisper of a dark future; perhaps darker than anyone can imagine.
This image depicts the most commonly-found stylesheet colors on the web’s top sites—Paul Hebert did an amazing amount of analysis and this is just one of the intriguing visualizations he came up with. Most of these are obvious staples, especially HTML red and blue, though it’s interesting how far the blue “cluster” is from the […]
With the cacophony of an election year ablaze with unparalleled drama being fought on the front lines of Twitter, we find ourselves slowing down and staring at it like a bad accident. The need for escapist relief is perhaps more dire than usual right now. This fall, if it’s drama you crave, but the Hillary […]
With Xamarin, coders can develop native apps for both iOS and Android without learning two different programming languages. Obviously, hiring one programmer rather than two is beneficial for companies and makes Xamarin experts highly in demand.You can easily learn Xamarin online with this Xamarin Cross-Platform Development Bundle. It will teach you to use Xamarin and code […]
TV antennas are making a comeback, and the Ghost Indoor HDTV antenna is a great example of why. Unlike the old bunny ear-style antennas, this compact antenna is barely noticeable and picks up channels easily. Plus with the addition of streaming services like Netflix, we find ourselves with plenty to watch without a pricey monthly cable bill. The Ghost […]
I’ve never really felt the need to purchase a smartwatch because a lot of them aren’t very functional, but at just shy of $30, the Martian Notifier Smartwatch was worth checking out. For that low of a price, it actually does feature an impressive amount of functionality, and comes in handy when you don’t want to be carrying around your […]
