"The MicroGame is an experiment of making a custom portable platform for gamming compatible with Arduino. It’s based on a small monochrome 128×64 pixels OLED from Adafruit and a ATmega32U4 8-bits microcontroller running at 8MHz. All hardware design and game source code is writed from scratch by me."

"OpenMV Cam gives any project the power of advanced machine vision with the ease of writing simple Micro Python scripts. More than just a camera board, OpenMV Cam is a complete vision solution that uses a simple IDE, rapidly integrates into any hardware project, supports shields for expanded capabilities, and already has a community behind it."

"This small board provides an easy way to record sound and transmit data to the mainboard’s microcontroller. Recording is done using an electret microphone, amplified with a LM386 sound amp. op. Output can directly be wired to the analog-to-digital (ADC) pin of the microcontroller."

"Our vehicle uses optical sensors to follow a line on the floor. Some autonomous vehicles used in manufacturing use a similar concept, following magnetic strips embedded in the factory floor. The versatility of an optical design should be readily apparent, since re-routing the vehicle requires no more than re-painting a line."

"Good news everyone, another step completed in my window garden. This is just a plain PIC 16F877A microcontroller with a 20MHz resonator and a character LCD. There is also a big photo-resistor for shits and giggles and some neat buttons. I got a dual relay board from eBay to turn the pump on and off, and an extra socket for a light down the road."

"It takes just few components to get the ENC28J60 up and running and connected to a host microprocessor or microcontroller with support for the industry standard SPI interface. This project includes the schematics and related information for a simple hardware implementation based on the ENC28J60 (ENC) and a Microchip PIC18F 8-bit microcontroller running Microchip’s free TCP/IP stack."

"Here’s an application to control the brightness of an RGB LED strip wirelessly (via Bluetooth) using a smartphone. The whole project is presented in a dedicated Bluetooth shield for Arduino and a RGB shield."

"The Final Key is a piece technology that solves a problem. The Final Key is a hardware password manager with encryption and focus on combining portability, compatibility security and easy of use. It is a hobbyproject of mine and not under any commercial distribution, you are also free to build your own clones if you like the idea."

"The programming for this is actually kind of interesting. Every time you push the button, the AVR retrieves the currently-displayed number, and then increments it, clicks the counter, and tests for primality. If the number isn’t prime, it increments and clicks again. When a prime number is reached, it stops and waits for another button press."

"…I thought I should experiment with etching first….Etching removes all exposed copper from the board. So, before etching, you must somehow cover and protect the parts you want to keep. You can draw the tracks, using a permanent marker. It is also common to laser-print them on paper, and then iron on the toner. The photosensitive boards are coated with a special layer, that dissolves in the developer, when previously exposed to UV light…"
