A new guide in the Adafruit Learning System: Adafruit 1.9″ Color IPS TFT Display.

This lovely little display breakout is the best way to add a small, colorful, and very bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and only a few pins available! The 1.9″ display has 320×170 16-bit full-color pixels and is an IPS display, so the color looks great up to 80 degrees off-axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and the Adafruit Arduino library supports it well.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator, auto-reset circuitry, and a 3/5V level shifter, so you can use it with 3.3V or 5V power and logic. We also had a little extra space, so we placed a microSD card holder, so you can easily load full color bitmaps…

A new guide in the Adafruit Learning System: Adafruit 1.47″ Round Rectangle TFT Display.

Don’t be such a square – throw a curveball into your electronics with a curved-edge miniature display. Here’s a new “round rect” TFT display – it’s 1.47″ diagonal and has high-density 250 ppi, 172×320 full-color pixels with IPS any-angle viewing. We’ve seen displays of this caliber used in smartwatches and small electronic devices, but they’ve always been MIPI interface. Finally, we found one that is SPI and has a friendly display driver, so it works with any and all microcontrollers or microcomputers!

This lovely little display breakout is the best way to add a small, colorful, and very bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.47″ display has 172×320 16-bit full color pixels and is an IPS display, so the color looks great up to 80 degrees off-axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well.

When I was a young teen, my friends and I were obsessed with building our own go kart. We made a rickety frame out of plywood and 2x4s and outfitted it with plastic mower wheels. The seat was a sawed off lawn chair. We longed for an engine to drive it. We found several lawn mower engines in a town dump and tried to cobble the parts from them to make a working one, but to no avail. We, of course, had no real mechanics skills at 13.

Seeing this video, I wonder if we wouldn’t have tried using a battery-powered drill as is used in this project (if such a thing existed back in the Jurassic era of my childhood).

From the first time I spotted a cluster of mushrooms at the base of a tree in my childhood backyard that sprouted during an overnight rainstorm, I knew that there was something kind of magical about mushrooms and how they grow. This video from Another Perspective on YouTube distills that magic into a well-shot and well-edited timelapse video of mushrooms grown at home.

Hundreds of hours of filming, photographing and editing. After one year of filming macro time lapse of 9 different types of fungi I grew in my basement, I finally finished this project pressing 5TB of image data into a 3 minute time lapse video. During that year, my camera equipment had to deal with spores and high humidity but took no visible damage.

This list from Tor.com has SO many of my personal faves (Totoro, the Lorax, Tom Bombadil?!?!).

The Ents count among Tolkien’s Green Man stand-ins as well, but old Tom Bombadil is certainly more… interesting. Left out of the LOTR films to the dismay of many fans, Bombadil doesn’t serve a plot purpose in Fellowship of the Ring, but he sure is fun to run into as interludes go. With his fancy lady of the river, Goldberry, and his odd yet powerful tunes, Bombadil gives the hobbits a place to nap after saving them in the Barrow-downs by frightening off a few nasty wights. With his home in the Old Forest, Bombadil remembers events on Middle-earth that no other living being can attest to—it would seem that he has always been there, and always will be. With abilities that no one quite understands, Tom stands apart from the rest of Middle-earth’s people, with Gandalf going so far as to say that the One Ring would hold no temptation for Bombadil… but he might simply misplace the darn thing.

Ipad Case Quick Release Mounting Mechanism by RAF1K Thingiverse

RAF1K shared this project on Thingiverse!

I designed this simple mounting system to be able to quickly mount and unmount an iPad to a suction cup. My main purpose for this is to mount an iPad to the windshield of an aircraft to run Foreflight.

I assume others might find similar use cases for this. It is substantially cheaper to build this than to buy some of the options on the market. Just because operating an aircraft is expensive, it does not mean that simple aviation tools need to be expensive.

While I do provide instructions/BOM on installing this part to the specific Ipad case I bought, you can choose the case of your choice. I would recommend a sturdy one with a hard shell. You could also install the part using epoxy instead of screws to prevent the need for drilling into a case.

Get up and running (tapping, free-falling, whatever!) in no time with this quality 3-axis accelerometer.

The ADXL345 breakout board, now with STEMMA QT, has a wide sensitivity range and high resolution, operating with an 10 or 13-bit internal ADC. Built-in motion detection features make tap, double-tap, activity, inactivity, and free-fall detection trivial.

The Analog Devices ADXL343 Breakout guide has been updated to include the STEMMA QT version of the board. There is now a Pinouts page, new wiring diagrams, and new downloads resources.

The Hill House, in Helensburgh, Scotland, is considered an architectural treasure. Designed by Charles Rennie Mackintosh (one of Scotland’s most famous architects), and built in 1902, it used ideas that were decades ahead of their time. One of those experimental ideas turned out to be a huge mistake.

Portland cement was used on the exterior, in a mixture that contained no lime. This has caused the exterior of the building to absorb huge amounts of the rain that constantly falls in this area, the wettest in Scotland, and over the decades, Mackintosh’s domestic masterpiece has literally begun to dissolve (“like an aspirin in water”).

To give the building time to dry out so that it can be properly preserved, The National Trust of Scotland came up with an ingenious plan. After a scaffolding was erected around the entire house and a roof put on over it, the walls of the enclosure were built from 30 million chainmail links. This chaimail curtain allows the house and grounds to breathe while the roof keeps the house dry. It will take years for the building to dry out before preservation efforts to take place.

When my son was in grade school, he came home one day with an awesome robotic arm that he had made in industrial arts. It was made out of wood and simple hardware. The actuation was provided by water in plastic syringes and hosing. A controller was made by slotting the syringes into a game controller-like piece of wood you held in your hands. I thought the idea was ingenious and had never seen it before, even thought I had just recently published a book on hobby robotics.

In this quick Adam Savage video, he presents the same idea. Two large syringes, some tubing, and some water, and you have a very cheap and surprisingly strong actuation solution.

How cool is this one-person steam-powered vehicle (made from car, bike, motorcycle parts and a 55-gallon drum) that runs on water and wood?

I love how he refuels the vehicle by scrounging for firewood and even refuels himself with sausage on the fire while he’s waiting for the boiler to re-pressurize.

we spent today working on a ESP32-S3 feather. you may be thinking “hey wait didn’t you already design one?” yep! but we had a hardware bug that increased deep-sleep power, and so we wanted to revise the ESP32-S2 feather first to fix it since the PCBs for the two designs are shared. now we have the new ESP32-S2 in the shop with the fix https://www.adafruit.com/product/5303 so we can respin the S3. even better, Espressif has started adding S3 support in a branch so we were able to test the GPIO, I2C, UART, NeoPixel, low power, and WiFi capabilities successfully. We’ve got a PR open to add this new board – it’s very exciting! https://github.com/espressif/arduino-esp32/pull/6450 This board uses the only S3 mini module available right now, with 8 MB of Flash and no PSRAM. however, there’s more SRAM on the S3 than S2 so its still very usable. when the PSRAM-containing mini module comes out we’ll make a version with that too – video.

Such beautiful, crazy twists and curves on this wooden bench. Maker André Göbel achieved this amazing look by steam-bending the wood and holding it all together using dimensionally stable epoxy resin adhesive. Imagine the recoil forces this thing is under.

As with other videos on André’s channel, there are a ton of great tips shown during the build. It even features the workpiece-transport clamp he built out of a skate wheel and an F-clamp. I featured this awesome little DIY shop tool in my latest tips book.
