I'll be showing and telling one of my projects in today's SHOW and TELL, hosted by John Edgar Park. The fun starts at 5:30pm ET / 2:30pm PT today.

We (Adafruit) are mixing things up and running a show and tell after John Park's Workshop on Thursdays!

My friend John Edgar Park made this cool MIDI controller in a pizza box with a conductive ink surface.

The Adafruit KB2040 – RP2040 Kee Boar Driver is a development board designed specifically for custom mechanical keyboard projects ("keeb" builds). It uses a Raspberry Pi microcontroller chip and can be programmed with CircuitPython, MicroPython, or C/C++. It's only $8.95.

Our friend John Park used one to create a keyboard that runs Doom when you press a special key. — Read the rest

The most valuable object to have sunk with the Titanic wasn't the Heart of the Ocean necklace from the movie (of course), but rather a Neoclassical painting titled La Circassienne au Bain. Painted by Merry-Joseph Blondel in 1814, this colossal artwork met its watery fate aboard the ill-fated ship. — Read the rest

My friend John Edgar Park alerted me to these wireless LEDs "that are powered via induction, just like a toothbrush or iPhone charger." He has published a tutorial on how to add them to a model car.

I publish a weekly newsletter called Gareth's Tips, Tools, and Shop Tales. For the last two years, I've done a year-end best-of collection.

This year, I had too many great tips and didn't want the issue to get too long. — Read the rest

[UPDATE 10-16-2020 1:21pm PT: John said: "They're removing that sign. Here's the email I got from the city clerk's office: 'Thank you for your email informing the City Clerk's Office of the sign on the trash can.  The sign was placed there by accident just to direct voters to the location of the ballot drop box.   — Read the rest

John Park used a 3D printer, some Sugru moldable glue, and a variety of Adafruit electronics components to build this nifty robot companion based on Pathfinder from the game Apex Legends. I also entered Sugru's drawing for a free 3D printer.

John Park says: "I made this Keanu GIF player using an Adafruit PyGamer and SD card. It autoplays each GIF for 10 seconds before moving on to the next one. You can also use the L/R thumbstick controls to advance or go back." — Read the rest

MakeCode Arcade is a Scratch-like programming language for writing retro-style games. In this video, John Park shows how to make arpeggio music using MakeCode arcade. In the early days of video games, the existing technology didn't allow for chords, so arpeggios were a way to get the feel for a chord by playing all the individual notes in a chord as quickly as possible. — Read the rest

John Park conducted a video workshop on how to make a drum sequencer by putting black and white markings on a disc. When he spins the disk, a row of optical sensors trigger the different drum sounds. It could be used to sequence any sounds, visuals, or actions.

Artisan maker Dick Whitney modifies beautiful antique phones to offer Amazon Echo functionality. His goal with the "Alexaphones" and other creations is to "combine classical design and usability with the most salient elements of your modern world." Unlike other spying smart speakers, Alexaphone only listens when you lift the handset. — Read the rest

Portland-based musician Randall Taylor, aka Amulets, creates gorgeous experimental music performances from modded Walkmans and old multitrack cassette decks playing handcrafted tape loops, live guitar loops processed through circuit-bent pedals, field recordings and other sound sources. He calls his portable setup, featured in the video below, the Suitcase of Drone. — Read the rest

Gareth Branwyn of Make: has assembled a collection of the best of his Tips of the Week column from 2017. There are some gems in here, like John Park's method for twisting a pair of wires (above) and Becky Stern's method for "stripping, soldering, and shrink-tubing a cable splice. — Read the rest

Our friend John Park, maker of delightful electronic curiosities, has just posted a new tutorial. This time, he shows you how make a beverage cooler using using a thermoelectric cooling assembly.

Make a nice, cold beverage using thermoelectric cooling! Peltier cooler + Trinket M0 + CircuitPython = refreshing drinks!

My friend John Park sent me the following:

This is an article about my old friend, UVa housemate, fellow Glee Club member, and all around wonderful character, D.R. Tyler Magill, who took on Nazis in Charlottesville and has now suffered a stroke.

Love puzzles, crypto, making, control panels and nuclear extinction? John Edgar Park has a maker project for you!

John Park made a couple of videos with instructions on how to make two very cool mystery boxes. One is a wood box that opens only when you place a special item on the lid. The other is a deck of cards that makes a Morse Code sound when the deck is in free fall. — Read the rest

John Park writes, "Check out what Tony D just posted at Adafruit after he visited the Living Computers Museum + Lab."

A few weeks ago my good friend John Park created a video demonstration of how to hack the famous Happy Chewbacca mask to trigger your very own audio files.  And when my sister Christina told me she was building a Chewbacca-Pinata costume for her son, I naturally shared John's video with her. — Read the rest
