DSL juniors – workshops for kids

DSL juniors – workshops for kids

Another exciting term we had with the DSLjuniors, a group of 4 kids aged 8 to 10 who come to DSL on Saturdays for a morning of making and learning about electronics. We wired our projects, soldered our PCBs and used hot glue to put laser cut parts together. This term we built an Arduino powered robot, with… More …

Made at DSL: laser cut topographical map

Made at DSL: laser cut topographical map

After making lots of laser cut boxes, i was wanted to try making a more interesting 3D shape such as a topographical map of my favourite island of Lantau. There are quite a few ways to do this, with the easiest way probably via an STL file but as i’m not familiar with any 3D printing programs… More …

Made at DSL: power meter over WiFi

Made at DSL: power meter over WiFi

DSL gets high electricity bills, that’s why i built an AC power monitor to log the electricity consumption. It is based on the excellent open source OpenEnergyMonitor project which i also use at home (nodes based on Arduino with RF modules). For DSL, i used an ESP8266 to be able to post the data over WiFi straight into the… More …

Made at DSL: Auduino 4-step sequencer

Made at DSL: Auduino 4-step sequencer

The traditional Arduino boards, with 8 bits at 16MHz are quite limited for sound processing, but the Auduino code, a ‘lo-fi granular synthesizer’, does generate an interesting sound. I combined this with a 4-step sequencer to produce some loops. Each red pot controls the pitch of its step (pentatonic scale). As the Arduino UNO only… More …

Made at DSL: WiFi lantern with RGB strip

Made at DSL: WiFi lantern with RGB strip

Inspired by the RGB LED ceiling lights at DSL, i made a lantern based on the same ESP8266 chip, but using the Arduino IDE to program it. I used the original ESP-01 package which has only a few GPIO pins available but enough for this application. The only other component is a voltage regulator that… More …

DSL Junior Makers – electronics workshops for kids

DSL Junior Makers – electronics workshops for kids

In October we started with a series of electronics workshops for kids. We had a group of 4 kids aged 8-10 and introduced them to electronics and Arduino, by building simple projects connecting components on a breadboard. They built the projects by themselves, based on a drawing showing the connections. We learned about batteries, LEDs,… More …
