The original Piezoelectric micro air Blower had a good run on Tindie, but now microwavemont is back with version 2.0. The new version has a built-in LDO for more stability in the supply voltage variation.
Since this Piezoelectric Micro Air Blower V2.0 doesn’t have a motor or fan, it instead uses an ultrasonic 26kHz signal and acts as a tiny air pump. Some use cases include water aeration, kinetic actuation, making small items hover, or even using it as a notification for the hearing-impaired (by using air flow).
The lightweight design and small form factor makes it easy to implement into your projects. There’s also no need for a high voltage source or an oscillator circuit. You only need to provide a 3.4V-5V power supply.
We at Tindie love a bit of retro-tech, and what better way to enjoy the sounds of the late 80s and early 90s than listening to your favorite Chiptunes? The Simple Chiptune Player puts the power of sonic nostalgia in your pocket, with a simple programmable signal generator to load full tracks and sound effects to play back and enjoy.
The player uses Yamaha’s Programmable Signal Generator (PSG) chip, the YMZ294, to generate the sweet bleeps and bloops. An ATmega328 handles the playback and can be programmed over USB using the Arduino IDE.
There’s a built in speaker for standalone playback, as well as a 3.5mm headphone output. Here’s a nice overview of the layout and workings of the player:
The Simple Chiptune Player is sold by microwavemont, coming from Japan and usually ships from there within one day. A selection of example sketches to get you started are available on GitHub.

Pi Wars 2019 is just around the corner! To coincide with the 50th anniversary of the Apollo moon landings, this year’s competition is space exploration-themed. For the uninitiated, Pi Wars is an international, challenge-based robotics competition. Teams are tasked with building Raspberry Pi-controlled robots and competing in non-destructive challenges to earn points.
The Pi Wars obstacle course in 2018
The contest spans over a single weekend and supports up to 76 teams from all over the world. This year marks the fifth iteration of Pi Wars, which takes place March 30th and 31st in Cambridge, UK. Schools and kids clubs will compete on Saturday, while beginners, intermediates, and advanced teams compete on Sunday. If you’re interested in spectating, tickets are still available. You can also follow along on Twitter by tracking the hashtag #PiWars.

Tindie & Pi Wars 2019
We are proud to be sponsoring Pi Wars this year by offering a gift card and Tindie Blinky Badge Kit to the 120+ members of the participating teams. While we can’t be there in person this year, last year we had a blast participating in the marketplace and meeting such an inspiring and dedicated community.

Special thanks to Michael Horne, Tim Richardson, and all of the amazing volunteers and sponsors that make this unique competition possible. And of course, we wish all of the 2019’s teams the best of luck!
My dad is not quite the gamer that I am, but one thing we’ve always had in common is a mutual love for flight simulators. These hyper-realistic experiences are even better when you have equipment like a joystick or throttle that adds to the immersion.
Another popular role is to handle radio communications from the air traffic control tower. That’s where the Flight Simulation Radio kit comes in. This kit is compatible with X-Plane using ArdsimX, but it’s also usable with Microsoft FSX and Prepar3D (with limited support).
The kit comes complete with everything you need, but some basic soldering skills are required. You can even daisy-chain kits together to form a full radio stack. The radio is programmable for Nav, Comm, Transponder, ADF, Groundspeed, or any other output from the simulator.
Having seen some of the incredible wearable fashion out there, I’m convinced that the intersection of tech and fashion is the future. Not only are clothes like this unique and interesting, but in many cases they’re also incredibly functional.
While we wait for wearable fashion to catch on, options like these Halopixels offer the chance to spice up your wardrobe with a little programmable pizazz. With 12 RGB addressable LEDs and a small form factor, this device works well as an earring, ring, pendant, necklace, or anything else your imagination comes up with.
It’s about the size of a coin, with a fully charged 3.6V 2032 coin battery delivering 3 hours of continuous battery life. By using your own BLE microcontroller, you can program the LEDs and customize both the color and blinking pattern.
There’s no denying the aesthetic quality of an aquarium. There’s a reason why you see them in lounges, offices, and the like. That being said, they can be a lot of work to keep your aquatic friends happy and healthy.
Thanks to the DOMOVOY, you won’t need to worry about keeping them fed. This automatic fish feeder allows you to set specific times for dispensing food. A proprietary algorithm also prevent jams in the feeder. You can even control it remotely via a smartphone or integrate it into a larger smart home system.
It supports dry, finely granulated, or flake fish food. With a 3D-printed case and a convenient display, this is one solution that’s easy to implement and takes another task off of your daily list.
For a beginner, the world of electronics, hardware, and circuits is a daunting prospect. Finding out where to begin with it all is a monumental task, but it doesn’t have to be. Thanks to makers all over Tindie, beginners have more resources now than they ever have in the past to dive into this vast and rich world.
The Edu-Kit 01 is an introduction to electronics and circuits that allows you to carry out ten different experiments. At the time of this writing, the instructions are only in Italian, but I’m sure there’s a linguist out there who will help translate them into other languages.
For those who read Italian, the instructions provide all of the steps needed to create the electronic circuits in each experiment. The kit includes a prototyping board, electronic components, and cables that you can use without the need for complex assembly.
The experiments include things like turning on an LED, learning about Ohm’s law, creating sounds with a buzzer, light sensors, and plenty more. The components in this kit are perfect for beginners to work on their own experiments as well!
Modular units are all about versatility and multi-functionality, with many users after a device which is flexible and can be applied to numerous sonic scenarios. Blinkenlights have released their Vactrol Drum for Eurorack which delivers a huge range of real and unreal drum and percussive sounds for your modular noodles requiring low end thunder and high frequency sizzles!
The Vactrol Drum employs a white noise generator (similar to the Roland TR-808) through a vactrol filter and VCA to generate kick drums, rimshots and hihats, as well as alien bleeps, squeeks and crashes. Controls include amplitude, resonance, attack, decay, bias and pitch envelope with gate and trigger inputs – to sculpt the sound depending on what you need. The unit has voltage controlled pitch, and can work as a noisy oscillator which the resonance turned up!
It comes as a PCB and panel with an extensive build guide (PDF), with BOM, schematics and test instructions to ensure it’s all good – the PCB silkscreen shows the names and values of all the components which makes construction that much easier! The finished unit is 4HP wide, 3U High and 100mm deep, and available now from the Blinkenlights Tindie Store!
If there’s one thing we’ve all lost at one time or another, it’s the remote. As a kid, I remember my parents always asking where the TV remote got off too, and it was often in obscure places. To this day, I still find myself wandering the living room at night hunting down that illusive piece of hardware.
One thing I’ve never lost track of, however, is my smartphone. For many of us, these devices might as well be attached to our hands. If you find yourself without a remote for your smart TV, or you want to use your computer away from the desk, MyTeletouch offers an interesting solution.
This simple USB dongle plugs into your computer or smart TV and then pairs it to your smartphone via Bluetooth. All you need beyond the hardware is a free app which is available on Android, iOS, and Windows app stores.
Once you’ve made the connection, you can switch seamlessly between mouse, keyboard, and joystick functionality right on your phone. While there are still some kinks to work out in the software side of things, the video below shows that it’s working pretty well!
With the PlayStation 4 as the main focus of console gamers, the PS3 and its DualShock 3 controllers haven’t had a lot of love in recent years. If you have any sitting around collecting dust (guilty!), the Axisdapter can give them a new lease on life.
This PCB connects to the flat ribbon connector on the main PCB of the PS3 controller, something only the OEM models have (so no third-party ones). Once installed, the buttons on the stock controller are replaced by the terminal blocks on this PCB. However, the stock controller retains the gyroscope and thumb sticks, which opens up the possibility to make flight stick builds or other types of custom controllers.
Freneticamnesic created this board and used it to help them turn a DualShock 3 into a virtual pinball machine controller, but the possibilities go far beyond that. You’ll need to sacrifice a DS3 for this project, but it’s for a good cause!
