Wifi/FTP camera with ESP8266 and serial camera PTC06 (and PTC02/PTC08)

Wifi/FTP camera with ESP8266 and serial camera PTC06 (and PTC02/PTC08)

Combining various sources of code, i built a cheap web camera that sends an updated image to a web server every 2 minutes. It is based on the ESP8266 wifi module, programmed with the Arduino IDE, and a serial camera (TTL level)

Arduino scoreboard for foosball table

Arduino scoreboard for foosball table

My son was super excited with his junior foosball from Shenzhen. It was easy enough to assemble, and worked well except for the plastic scoreboard. An excellent opportunity for an electronics project! Actually the electronics are fairly simple: an Arduino Nano an

IoT clock with LED matrix (Arduino & ESP8266)

IoT clock with LED matrix (Arduino & ESP8266)

This box shows the time (NTP sync) and a few data feeds of my home monitoring system. It uses a 32×16 LED matrix driven by an Arduino Nano, and ESP8266 Wifi module (NodeMCU v1). I put it in a laser

Low cost basic Polargraph

Low cost basic Polargraph

The polargraph is a fascinating vertical plotter, that uses two small motors and gravity to move a pen over a paper, controlled by software on a computer. Actually ‘polargraph’ is the name given to it by a guy who wrote an

Portable dust sensor (SHARP)

Portable dust sensor (SHARP)

This is an Arduino-based battery powered air quality monitor using the optical SHARP GP2Y1010AU0F dust sensor (or its more recent version the GP2Y1014). It reports values in micrograms per cubic meter, which is also the unit of PM2.5 and PM10. Having

Treasure Box with smart card lock (Octopus and Mifare)

Treasure Box with smart card lock (Octopus and Mifare)

My 8-yo daughter asked if we could put an electronic lock on her treasure box. I suggested we use her Octopus card (Hong Kong public transport smart card) to open and close the box. I had experimented a while ago

BuffaloBot (autopilot and R/C)

BuffaloBot (autopilot and R/C)

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

Pong and Gyro Game Box (Arduino)

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

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)

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
