Lightstorm Is an LED Control Module for Your Eurorack
https://blog.hackster.io/lightstorm-is-an-led-control-module-for-your-eurorack-7e436043fbf5
Euroracks are a popular modular solution for DJs to contain their music production tools in a single unit. Because Eurorack modules are standardized, musicians can mix and match whichever modules they prefer.
Now you can also add LED lighting control to your Eurorack thanks to Lightstorm.
The Lightstorm Module can be used to drive Adafruit NeoPixel-style individually-addressable RGB LED strips, and the Lightstorm Eurorack Case has LEDs built right into it

Rudimentary ultrasound machine made with Arduino Due
https://blog.arduino.cc/2019/04/19/rudimentary-ultrasound-machine-made-with-arduino-due/
Ultrasound images are an important tool for medical diagnosis, and while units used by doctors can be very expensive, getting a basic image doesn’t have to be. Inspired by this attempt at a $500 ultrasound machine seen here, maker “stoppi71” decided to create his own using a 5 MHz ultrasound transducer via a paint-thickness gauge.

This Is The Delay Pedal You Can Build Yourself
https://hackaday.com/2019/04/10/this-is-the-delay-pedal-you-can-build-yourself/
If you want to do something really cool, build a delay, because everyone needs another delay. If you want to build the latest in delay technology, just grab a PT2399 chip. That’s what ElectroSmash did with their Open Source Time Manipulator delay. Everything’s right there, all the parts of the circuits are described, and you too can become an effects pedal engineer.
This pedal is based on the PT2399 chip from Princeton Technology,

Turn On/Off TV Sound System Using the TV IR Remote Control © GPL3+
https://create.arduino.cc/projecthub/lugh/turn-on-off-tv-sound-system-using-the-tv-ir-remote-control-c0a8a4
How to control a PC sound system connected to a TV using the IR remote control power button, so both TV & sound system are on/off together.
I need an IR receiver module to be able to decode the signal sent while pressing the remote power button.
I also need to be able to switch on/off the sound system. Looking in the sound system wired command, I saw it has an on/off button. By soldering a wire on each terminals of this switch I can open/close the circuit using a relay module.
Once done, each time I push the power button of the TV remote control, both TV and audio system are ON (I’ve located the IR receiver close to the one of the TV, so they should both receive the same remote signal.). If I push the button again they are both turned off.

Connect Arduino to Breadboard Without Jump Wires
https://www.eeweb.com/profile/max-maxfield/articles/connect-arduino-to-breadboard-without-jump-wires
As soon as you see a BreadShield in action, you realize how much time you could have saved over the years, and at three for $15, the price isn’t bad either.
Hi, I’d like to report an open-source project that can greatly speed up prototyping with the Arduino. It can eliminate the pain of using jumper wires between the Arduino and a breadboard. It’s currently in a crowdfunding campaign. Here is the link: https://www.crowdsupply.com/loser/breadshield

Getting to know the new Arduino Nano 33 IoT
https://blog.arduino.cc/2019/05/24/getting-to-know-the-new-arduino-nano-33-iot/
As announced at Maker Faire Bay Area, the Nano 33 IoT is part of the new 3.3V variant of the family with an Arm Cortex-M0+ microcontroller and a pre-certified ESP32-based WiFi and Bluetooth module from u-blox that brings sophisticated connectivity to its tiny package. The inclusion of an ECC608A crypto chip means it also offers IoT security features not usually available at such a low price point.
