The Pico Macro Keyboard is a compact and powerful macro pad built using the latest Raspberry Pi Pico 2. Inspired by the Figma Creator Micro, this keyboard is designed for customizable control and enhanced productivity. It features mechanical switches with per-key RGB lighting, along with two rotary encoders for added functionality. With a modular 4-layer PCB and fully customizable keymaps, it seamlessly integrates with any software, making it perfect for designers, gamers, and power users alike.

Raspberrypi Pico-based sampler, sequencer + drum machine w/ an embedded speaker, Adafruit I2S amplifier and momentary step switches, evoking the tr808 synthesizer ⁠

Welcome to your new project. Imagine what you can build here.

R1 changes: -Changed LED part to Red LEDs -adjusted resistor value of buck converter -Changed source for USB-C Connector -Removed exposed soldermask on buck converter with negative soldermask expansion -Order with black soldermask Modified by markwu2001: - Adjustable Brightness, - 85-90% Drive Efficiency - <5W Operation (Can use 5V 1A Plug) This project can be purchased from LCSC Original Description: Daddy's second circuit board. A sign to let my wife know when I'm on a call. Activates with a slide switch and is powered by USB-C.

Control board for autonomous or radio-controlled robots. It has inputs to connect distance sensors and encoders for autonomous mode. It can be radio controlled by the ESP32 bluetooth or by connecting a Flysky RC controller receiver to the IBUS port. It also has 3 push buttons and you can connect some kind of display by I2C to visualize and select configuration modes.

BLE remote control board. Based on SoC ESP32-C3-MINI-1 that allows you to program it as HID volume multichannel control, you can switch channels with the user button, or use it as arrow keys.

Balancing board for zinc batteries controlled by ESP32 via IO expander. Information about the state of each battery will be uploaded to the cloud

DIY BMS using ATTINY841-SSU this hardware has a higher balance current, fuse and TVS diode to help with voltage spikes. Most importantly, an external crystal to the micro controller (attiny841) which means the device is more reliable in low voltage situations

Build your own Modular LED Sign! This design prioritizes accessibility which means that the BoM can be ordered on Amazon and that everything was designed with solder-ability in mind. NOTE: This board is still an unfinished prototype that has not been built and verified. Operating Instructions: 1. [Important!] Power your buck converter and adjust the output voltage to 1.5V output before attempting to power the LEDs. If you cannot power the buck converter, just turn the potentiometer counterclockwise to its maximum setting.

Change History from V1: -13.56MHz tuning -larger instruction font -put some stuff on the back I wanted to create a business card that has some functionality and shows off a bit of my portfolio IRL: -NFC to my flux page -here's the awesome [instructables](https://www.instructables.com/PCB-Business-Card-With-NFC/) -Put a bunch of modules on it Find the BoM [here](https://www.digikey.com/short/2db2vnmp)
