David Simenc on Building A Modular Joystick For Star Citizen.

Posted in hardware, how-to, News, Wireless Hacks Tagged ESP8266, internet of things, wifi Post navigation If you’re one of the unlucky one’s to receive the “magic smoke” releasing ESP8266 modules, then you don’t need the LED anyway. That, and also pry off the indicator LED’s with a screw driver! That sounds a bit drastic, and we’d recommend pulling out your soldering iron instead. needed to hardwire the ‘post-sleep-reset-pin’ on the MCU to the Reset terminal. But the real hack is on the ESP-01 module itself.

We’re guessing he (or someone else) will come up with a proper PCB to make things easier. built a Dev board on perf board that let him access these pins and also added some frills while at it. While was working on understanding the ESP8266 tool chain ( NodeMCU firmware > Lua interpreter > ESPlorer IDE), he realized that some essential pins weren’t accessible on the ESP-01 module. figured out a simple hardware hack to get the ESP-01 to go to deep sleep, effectively reducing its current draw to 78uA – low enough to allow battery powered deployment. So, it’s no surprise that ways to cut down on the juice that this device consumes is top priority for many people. The one thing that such radios do a lot is suck power. For about 5 bucks, it can’t be beat on price for the features it offers.

The ESP-01 module based on the ESP8266 is all the rage with IoT folks at the moment – and why not.
