Kids love robots. And parents seem to like the idea that their kids are learning about robotics. So i came up with the BuffaloBot for my students: a 2WD Arduino robot with geared motors on a laser cut design of
BuffaloBot (autopilot and R/C)
Pong and Gyro Game Box (Arduino)
For my kids workshops i always try to come up with new Arduino games, and they really liked the recent Gyro game. I decided to make a laser cut box for it, and add a second game, Pong for 2
ESP8266 portable Internet radio
I have been building several sound boxes lately (amps, sequencers), and when i thought of making an internet radio, i found the excellent Esp-radio project using the Arduino IDE to program the ESP8266 WiFi module (ESP-12E version). The documentation is
Arduino gyro game (with MPU6050)
I made an Arduino game around the MPU-6050 sensor (6DOF = gyro+accelerometer) and an OLED display: tilt the sensor to move the ball around do not touch the borders try to catch as many squares as possible within 1 minute I’m
Arduino walkie talkie with nRF24L01
One of the more popular projects i build with kids is my Arduino Morse radio, so i started to wonder whether the nRF24L01 can also transmit sound. That’s how i found the excellent RF24Audio library. This library includes all basic
Auduino 4-step sequencer
This Arduino-based 4 step sequencer uses the popular Auduino code as synthesiser, with some simple additions to add a sequencer to the code (see below). When i was experimenting with the Atari Punk Console 8-step sequencer described here, i was
WiFi lantern with RGB strip (ESP8266)
In a previous project, i had connected an RGB LED to an ESP8266-01 to be able to change the colour over WiFi. This time i am going to use an 8-pixel Neopixel RGB strip, which only requires 1 digital pin
Stereo speaker project for kids
As my kids were quite excited with my BuffaloAmp project, i organised a speaker building project for my kids workshop groups. This project has evolved a bit over time, the current version uses a laser cut tabbed box with 2x 3W
Stereo amp on Lithium batteries
My kids love to play music from their phones so i wanted to build them a portable amplifier, a low cost version of the Blueshift, without Bluetooth, and with recycled laptop batteries (2x 18650). As i also had a pair of
Arduino compass (HMC5883L) with OLED screen
A simple compass, using the HMC5883L chip, on a breadboard with an Arduino Nano and an OLED screen. Compass connection is over I2C, the screen uses SPI. I decided not to use a library for the HMC5883L but keep it
