Hackaday Links: May Day, 2016

Humble Bundle is a great way to fill up your Steam library – just pay what you want, and get some indie video games. The Humble Bundle is much more than video games, because No Starch Press just put up a bundle of books on hacking . No, there are no books about wearing balaclavas and using laptops with one hand. I haven’t written that book yet. There’s some choice books in this bundle, including [Bunnie]’s  Hacking the XboxAutomate the Boring Stuff with Python,  and  Practical Malware Analysis.

The Raspberry Pi camera – the $25 add-on webcam that plugs directly into the Pi – is getting an upgrade . The original camera was a five Megapixel sensor that was EOL’d at the end of 2014. The Raspberry Pi foundation bought up a lot of stock, but eventually there would be a replacement. The new sensor is a Sony IMX219 eight Megapixel deal, available at the same price. We assume a NoIR version without the IR filter will be released shortly.

Here’s a little hardware review that doesn’t quite merit a full post. The Raspberry Pi Zero is great, and will be even better once production ramps up again and stock lands in warehouses. One problem with the Zero is the lack of USB ports, leading to at least two Hackaday posts with the exact same headline, ‘ Yet Another Pi Zero USB Hub ‘. Obviously, there’s a market for an easy to use USB hub for the Zero, and this company is stepping up to fill the need. The killer feature here is the use of pogo pins to tap into the USB differential lines, power and ground pads on the bottom of the Pi Zero. The USB hub is based on the popular FE 1.1 4-port USB hub controller, giving the Pi Zero four USB 2.0 ports. Does it work? Yeah, and it’s only $10. A pretty neat little device that will be very useful when Pi Zeros flood workbenches the world over.

It was announced in 2014, released in 2015, but the STM32F7 hasn’t seen a lot of action around these parts. A shame, because this is the upgrade to the famously powerful STM32F4 microcontroller that’s already capable of driving high-resolution displays through VGA , being an engine control unit for a 96 Ford Aspire , and being a very complex brushless motor driver . The STM32F7 can do all of these and more, and now ST is cutting prices on the F7’s Discovery Board . If you’re looking for a high-power ARM micro and don’t need to run Linux, you won’t do better elsewhere.

Need to reflow a board, but don’t have a toaster oven? Use a blowtorch ! By holding a MAPP blowtorch a foot away from a board, [whitequark] was able to successfully reflow a large buck converter. There’s a lot of water vapor that will condense on the board, so a good cleaning afterward is a good idea.

A few weeks ago, [Mr. LeMieux] built a 360 degree, all-metal hinge . He’s been up to something a little more dangerous since then: building piles of mini table saws . Small table saws are useful for miniatures, models, and the like. [Mr. LeMieux]’s table saw is a piece of CNC’d aluminum, with a bearing and saw arbor that attaches to an electric drill. Dangerous, you say? Not compared to the competition. Behold the worst forty dollars I’ve ever spent . This Horror Freight mini table saw is by far the worst tool I’ve ever used. The bed was caked with streaky layers of paint, uneven, the blade  wasn’t  set at 90 degrees, and the whole thing was horrifically   underpowered. Trust me when I say the CNC electric drill version is safer.
