In this GreatScott video, he adapts an 18v 5.0 Ah Makita battery pack to his portable vacuum.
Besides this useful hack, the video also provides a fascinating teardown of the vacuum electronics and mechanics, all detailed using Scott’s clear and beautifully-drawn circuit sketches.
Here’s a fun kind of maker challenge. Alex Steele decided to see if he could recreate a classic Zippo lighter.
As you might image, such a challenge might be easier (for someone of Alex’s skill) than you think. Or that Alex thought. This will be a multipart series.

We promise this playlist is going to hit anyone living life and listening to new releases in the mid aughts hard in the heart. Get ready for serious emotional waves and absolute bangers in this Spotify playlist World Cafe put together for their 30th anniversary.
The year was also notable for music by bands-on-blogs — which would become something of a sub-genre also known as “blog rock” — that’s best represented by Clap Your Hands Say Yeah, whose 2005 debut still stands as a classic.

That may soon change. Boris Knyazev of the University of Guelph in Ontario and his colleagues have designed and trained a “hypernetwork” — a kind of overlord of other neural networks — that could speed up the training process. Given a new, untrained deep neural network designed for some task, the hypernetwork predicts the parameters for the new network in fractions of a second, and in theory could make training unnecessary. Because the hypernetwork learns the extremely complex patterns in the designs of deep neural networks, the work may also have deeper theoretical implications.

We all love watching YouTube project videos when the build goes seamlessly. But it’s often more educational, to both the Tuber and the viewer, when there are issues with the design and execution of the project.
Such is the case with this project by Laura Kampf. She wanted to build a simple dispenser that would automate the delivery of cutting oil to her drill press. She even found a cute coffee maker that was the perfect size. Laura encounters one problem after another and comes up with great solutions for each.
But after the oiler is finally installed, she ends up with another annoying problem — the device leaks oil when not in use. She ends the video with this quandary, but folks in the YouTube comments have the solution:
The solution is simpler than you think: put the coffee maker lower than the liquid outlet point. In this position, the pump fills the siphon which then continues to drain until the coffee maker is empty, with the coffee maker at the bottom instead, the liquid will return back by gravity.

Were you aware that batteries can flip their polarities? I wasn’t. Fran Blanche discovered this while testing some Rayovacs that have been in the Star Trek Comm Panel that she hacked years ago.
Fran discover that one of 3 AA batteries in the toy had switched polarity. In the comments EEVBlog wrote:
Yep, this can happen if you have non-matched cells in series, or one dodgy one. The lower charge one discharges first and then the others in series push current through and reverse charge the dead one.
Many products have a warning not to mix fresh and used cells for this reason. This has popped up quite a few times in my videos over the years.
And, are Lithium cells vulnerable to this, too? FellenXD writes:
Very much so, and it can lead to growth of lithium metal crystals that can puncture the insulating membranes in the battery. This will cause a short circuit inside the battery and can lead to some explosive spontaneous self-dissasembly
Proper battery packs have balancing circuitry for the cells and a low voltage cutoff, which should stop this from happening.

Through a piece on Boing Boing, I learned about this promising-looking comic, called Terrorwar, from Saladin Ahmed (with art by Dave Acosta).
Author Saladin Ahmed’s…new venture, The Copper Bottle, tells a variety of fantastical stories with help from a rotating group of artists.
One of those stories — sort of the main feature of the publication right now — is Terrorwar, which is a delightful cyberpunk riff on terror in all its forms, with art by Dave Acosta. The story follows Muhammed Cho, a “terrorfighter,” or sort of a freelance hitman in the literal war on terror. Except in this case, the Terrors are literal manifestations of our personal greatest fears, which threaten to come to life and kill us. Being that Ahmed is a Muslim-American, and that he has not shied away from exploring that identity in his previous work, I suspect there will be some interesting thematic subversions around the way we demonize certain groups (even if they are Literal Manifestations Of Our Fears).

Join Scott Friday, January 28th, on Adafruit YouTube or Twitch at 2pm Pacific.
Join the Discord and ask to be added to the “Deep Divers” role to be notified of time changes or computer troubles.
The plan is to discuss the last few #CircuitPython2022 posts and go over BLE on the ESP32-S3 and C3 work.
Thanks to @askpatrickw and @dcd, all notes are available on GitHub with links into the videos.
Here is last week’s stream:
This week on the Adafruit Learning System, we published a few guides this week, and updated a whole bunch more. Build an arcade synth controller, 3d print a Feather TFT STEMMA case, build a Circuit Playground Bluefruit BLE heart rate pendant, and more!
Are you going to a dance party soon? Or maybe a speed dating night? Would you like to wear your heart out?
In this project, you can visibly show off your heart rate in the form of a pulsing pendant. A Circuit Playground Bluefruit (CPB) connects to a heart rate monitor to display the heartbeat of the wearer. Using the CircuitPython programming language, the CPB blinks with red NeoPixels to display the heart rate.
After reading John Park’s new Arcade Synth Controller build guide, I did some digging to find some of the more interesting projects on the Adafruit Learning System that utilize the greatest button of all time…the arcade button. Here are my favorites:
Use Arcade Buttons to play MIDI music
Build your own CircuitPython powered MIDI controller! This “MIDI fighter”-like controller features 16 arcade buttons with built-in LEDs, an OLED screen and joystick. Play drums, synthesizers or anything MIDI related! All of the electronics are housed in a snap-fit 3D printed case.
Build a Raspberry Pi Retro Arcade
In this guide, we’ll learn how to wire up a Mini Analog Joystick to the Adafruit Arcade Bonnet for Raspberry Pi. Most of the arcade buttons plug into the Arcade Bonnet with quick connect wires – Making it much easier to put together a retro arcade controller or cabinet.
Mapped for Livestream Studio, switch streams with big ole buttons
Sometimes you need one button for the job, and sometimes you need many.
This project is a fully enclosed 3D-printed Bluetooth controller, powered by a METRO 328 and LiPoly battery, mapped to use with Livestream Studio.
Using the serial input on the Bluefruit EZ-Key and some MCP23017 i2c expanders, there’s a whole load of buttons. Arcade buttons. Pushbuttons. Buttons and buttons and buttons!
Make your own awesome wireless MIDI controller guitar for rocking out
Rock out with your very own wireless Keytar, a bluetooth MIDI controller that works with any computer or tablet! Jam out with up to 12 buttons that can be customized to trigger sounds or effects.
This project uses the E-Z Key bluefruit wireless controller from Adafruit. The guitar features 4 arcade buttons and 6 LED push buttons. The guitar can be used as a MIDI instrument, video game controller and even DJ controller. You can customize and configure your guitar to be whatever you want.
The enclosure is 3D printed and you can download the design files from Thingiverse. This six-piece design is optimized for the MakerBot Replicator 2 build plate. Don’t have a 3D printer? You can always fashion your own guitar from wood, plastic (or cardboard??)
We’re using 4 neo-pixels and a mic as a level meter so the LED’s animate to the sound. The Flora micro-controller powers these components and uses a toggle switch and battery pack. The two back covers are designed to easily snap on and off to quickly get to the components.
With so many guides on the Adafruit Learning System, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface. This week’s guide is from back in 2017.
Turn a classic Atari joystick into a wireless controller with the Feather nRF52 Bluetooth!
Playing emulated games on an iPad or iPhone is a lot of fun, but one thing missing from the equation is a proper joystick. To fix this dire situation, you can take an original Atari 2600 joystick and turn it into a wireless controller capable of working with any iCade standard game!
The Feather nRF52 Bluefruit Bluetooth LE microcontroller is perfect for the task. It’s fast, has robust Bluetooth, and is tiny enough to fit inside the joystick’s case, along with a LiPo battery for power.
You won’t even need to modify the case, just remove the original cable and you’re ready to create a whole new, modern controller inside of the body of a classic!

Remix from 3DWaves Korg Monotron Series initial design and TheMadMartigan’s remix. This one is my own personal adjustment to put two units in a more traditional two tier setup with the units a bit tighter together. I also beefed up the legs a bit since, why not.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
