How to build your own DIY makeshift levitation machine at home • The Register

https://www.theregister.co.uk/2017/08/16/engineers_show_how_to_construct_makeshift_acoustic_levitator/ Engineers at the University of Bristol in the UK have published a rough guide to building a simple levitation chamber that uses sound waves to suspend objects. A paper published in the Review of Scientific Instruments this month shows how it can be done within the confines of your own home lab. Using a 3D printer, →

https://www.hackster.io/motea-marius/diy-complete-philips-hue-home-automation-dacb12?ref=channel&ref_id=425_published___&offset=0 This project looks like a very interesting home automation IoT project that provides tools for many applications: This project emulates a Philips Hue Bridge that is able to control Hue lights (using original Hue Bridge), IKEA Tradfri lights (usign Tradfri Bridge), Mi-Light bulbs (using MiLight Hub), Neopixel strips (WS2812B and SK6812) and any cheep →

Solderless breadboards

Solderless breadboards are one of the most fundamental pieces when learning how to build circuits and prototyping simple circuits. A breadboard is a construction base for prototyping of electronics. Breadboard are the ideal way to check out small bits of circuitry that you’re not sure about. Originally it was literally a bread board, a polished →

Secret chips in replacement parts can completely hijack your phone’s security | Ars Technica

https://arstechnica.com/information-technology/2017/08/a-repair-shop-could-completely-hack-your-phone-and-you-wouldnt-know-it/ Booby-trapped touchscreens can log passwords, install malicious apps, and more. People with cracked touch screens or similar smartphone maladies have a new headache to consider: the possibility the replacement parts installed by repair shops contain secret hardware that completely hijacks the security of the device. The research, in a paper presented this week at the 2017 Usenix →

Web-Based Universal Remote for Under $4 (Probably) – Hackster.io

It’s cheaper, funner, universal-er, kind of, and you get to learn the ESP8266, kind of. You will need the Arduino IDE with whatever OS. Alternatively Linux and some C skills for the official Espressif stuff, but that’s unnecessarily challenging for this application. To get IR control codes →
