A Stylish Home for your Next ESP Project

The ESP8266 and ESP32 are fast becoming the microcontroller of choice for, well, everything. But one particular area we’ve seen a lot of activity in recently is home automation; these boards make it so incredibly easy and cheap to get your projects online that putting together your own automation system …read more

ESP32 Alarm Clock Doesn’t Skimp On The Features

The ESP family of microcontrollers is absolutely on fire right now, with a decent chunk of the projects that come our way now based on one of the impossibly cheap WiFi-enabled boards. In fact, they are so cheap and popular that we’ve started to see a somewhat unexpected trend; people …read more

ESP8266 Gets Its Game On With Open Source Engine

This is likely not to come as much of a shock to you, but the ESP8266 is pretty popular. At this point, we’re more surprised when a project that hits the tip line doesn’t utilize this incredibly cheap WiFi-enabled microcontroller. If you’re making a gadget that needs to connect to …read more

Burn Some Time with this Arduino Reddit Browser

If you’re like us, you probably spend more time browsing Reddit than you’d like to admit to your friends/family/boss/therapist. A seemingly endless supply of knowledge, wisdom, and memes; getting stuck on Reddit is not unlike looking something up on Wikipedia and somehow managing to spend the next couple hours just clicking through to new pages. But we’re willing to bet that none of us love browsing Reddit quite as much as [Saad] does.

He writes in to tell us about the handheld device he constructed which lets him view random posts from the popular /r/showerthoughts sub. Each press of the …read more

Blazing Fast Raspberry Pi Display Driver Will Melt Your Face then Teach You How

Reader [poipoi] recently wrote into our tip line to tell us about an “amazingly fast” Raspberry Pi display driver with a README file that “is an actual joy to read”. Of course, we had to see for ourselves. The fbcp-ili9341 repo, by [juj], seems to live up to the hype! The software itself appears impressive, and the README is detailed, well-structured, educational, and dare we say entertaining?

The driver’s main goal is to produce high frame rates — up to around 60 frames per second — over an SPI bus, and it runs on various Raspberry Pi devices including the …read more

ESP32 Display is Worth a Thousand Words

The ESP32 is the successor to the wildly popular ESP8266. There seems to be no end to what the chips can do. However, despite all the wireless communication capabilities, the module doesn’t have a display. [G6EJD] wanted to connect an ILI9341 TFT display and he put the code and information on GitHub. You can also see a video of his work, below.

Since the display uses a serial interface, there isn’t much wiring required. The Adafruit GFX library does the heavy lifting, utilizing the SPI library for the actual communications. The first demo shown on the hardware can pull weather …read more

Everyone Loves Faster ESP8266 TFT Libs

Reader [Jasper] writes in with glowing praise for the TFT_eSPI library for the ESP8266 and the various cheap 480×320 TFT displays (ILI9341, ILI9163, ST7735, S6D02A1, etc.) that support SPI mode. It’s a drop-in replacement for the Adafruit GFX and driver libraries, so you don’t need to rework your code to take advantage of it. If you’re looking to drive an LCD screen with an ESP8266 and Arduino, check this out for sure.

As a testbed, [Jasper] ported his Tick Tock Timer project over to the new library. He got a sevenfold increase in draw speed, going from 500 ms to …read more

Nerd-Bait: ESP8266 + ILI9341 Screen

In honor of my-own-damn-self, we’re going to call it Elliot’s Law: “When any two interesting parts get cheap enough on eBay, someone will make an interface PCB for them.”

And so it is with [Johan Kanflo]’s latest bit of work: a PCB that mounts an ESP8266 module onto the back of an ILI9341 color display, with user button, power supply, and an auxiliary MOSFET. Four bucks for the screen, four bucks for the ESP8266 module, and a few bucks here and there on parts and PCB, and you’ve got an Internet-enabled, full-color, 320×240 graphical display. That’s pretty awesome, and …read more
