Collaborate Disseminate
Last month we brought word of the IKEA VINDRIKTNING, a $12 USD air quality sensor that could easily be upgraded to log data over the network with the addition of …read more Continue reading Hacked IKEA Air Quality Sensor Gets Custom PCB
You’ve probably noticed that the hacker world is somewhat enamored with overly complex electronic event badges. Somewhere along the line, we went from using a piece of laminated paper on a lanyard to custom designed gadgets that pack in enough hardware that they could have passed for PDAs not that long ago. But what if there was a way to combine this love for weighing down one’s neck with silicon jewelry and the old school “Hello my name is…” stickers?
[Squaro Engineering] might have the solution with Badgy, their multi-function e-ink name…well, badge. Compatible with the Arduino SDK, it can …read more
Connecting your shiny new ESP8266 to WiFi can be as simple or as complicated as you please. Most people decide to manually add it. Some people find clever ways to make the bloody thing connect itself. [Eduardo Zola] transfers his WiFi password using the flashing light of a smartphone screen.
A simple photo-resistor and a bit of tinkering allows him to easily send credentials — or any data really — to his ESP8266, through the power of LiFi. Short for Light Fidelity, LiFi transmits data using light with on and off states representing digital values. It can use visible light, …read more
[Vincent Deconinck] gave a fresh lease of life to an old set top box by adding a few Euro’s worth of hardware and some software smarts. The device in question is an old VOOcorder – a Cisco set-top box provided by VOO, his cable service provider in Belgium.
The VOOcorder doesn’t have any WiFi hardware or browser / app based interfaces. It’s a simple device controlled either via an IR remote or front panel buttons. [Vincent] added an ESP8266 and hooked it up to the IR receiver on the set-top box. He also set it up as an SPI slave …read more
[Buger] had an ESP-12F and wanted to play with nodeMCU, but found they were lacking buttons for reset & flash. We’ve all been there – mucking about with a project on a breadboard, trying to save the time required to solder up a button by shorting pins with wire or bending component legs to touch. This either doesn’t work or ends up bricking the microcontroller when it inevitably goes wrong. [Buger] found a tidier solution to adding buttons to the ESP-12F with the minimum of effort.
It’s the spirit of deadbug applied to buttons. One side of a piece of …read more
