#esp32

This turned out really well and was a cheap solution to my problems (it cost me about$16 but it currently shows me $21 for a screen). In the weeks since I set it up, it's been so useful for everyone else in the house that I'm considering buying one for the kitchen to control all the living room lights without anyone having to take their phones out, and another one in my barn to turn all the lights on whenever I walk in (currently I always fire up the Apple Home app and run a shortcut to turn on the 6 different light switches).

I have loved Metal Gear Solid since I was a kid. When I got a tiny ESP32-S3 board, one question stuck with me: could a PlayStation game run on something this small?

A long while back I had an idea to hack a WiFi smart light bulb to do something more useful to me. Actually, I had a few different ideas of things to do with them. One of these ideas was to modify the device to have an open WiFi access point and a web server hosting banned books. The idea was that if you lived somewhere that banned books you thought were important, you could theoretically stick a digital copy of the book on one of these light bulbs. Then you could go install it somewhere in your community. As long as the light bulb is switched on, then anyone in the vicinity can still access the banned material assuming they have an electronic device with WiFi. Since the device is a light bulb, it would be difficult to detect and likely to go unnoticed. A cyberpunk digital dead drop. These devices are also fairly inexpensive, so leaving them around town as is hopefully not very cost prohibitive.

A Hardware Hacking Tool with Web-Based CLI That Speaks Every Protocol

As I continue to try to unbundle my hobbies from the iphone, these ESP32 devices have played a really big role. An open product like this promises a tinkerer like me much more than a useful gadget - it can become MY gadget, something modified and tuned to my specific needs and aesthetic quirks. There is no corpo telemetry tracker sneaking onto my gadget, only the stupid shit I put there!! And when I get tired of that thing, I can always flash it with something else. I can't say that about my phone.

Play Galaga, Pac-Man, Donkey Kong, Frogger, Digdug and 1942 on the ESP32

Microcontrollers like the ESP32 with its dual 240 MHz cores can run circles around the CPU grunt of 1980s arcade hardware. Cue [Till Harbaum]’s Galagino ESP32-based arcade emulator project, that recently saw some community versions and cabinet takes.

mini shell for esp32

The thing is… it is made to run on an ESP12, which is very capable and very power efficient, but tends not to allow for external antennas and doesn’t have great WiFi range. I wanted more range. I want an external antenna. And I have a few spare ESP32’s sitting around that allow for external antennas and have better WiFi performance. So, I decided to try to port the firmware from the ESP12 to the ESP32.

This tutorial shows how to build an ESP32 web server that displays a web page with multiple sliders. The sliders control the duty cycle of different PWM channels to control the brightness of multiple LEDs.

The ESP32 requires no app, it can be controlled from any PC or mobile device that has a web browser.
