Gadgets the good doc has made
DR BALAKRISHNAN keeps his tech toys in square boxes. The boxes hold everything from microcontroller kits to a Lego Mindstorms tank that he built with his son Luke.
SPIKENZIELABS CALCULATOR KIT
"I got this calculator kit from 3E Gadgets and assembled it in a few days. It displays up to six numbers and even has a power-saving function, so the display turns off every 30 seconds," he said.
DEVICE FOR HIS AUTOMATIC GATE
"I made this device for my automatic gate at home. It contains microcontroller boards and relays, among other things. It is linked wirelessly to my phone. The gate opens only when a family member or I key in the correct passcode into a Web-based app in our phones."
"I got this from entrepreneur James Chan at tech company Silicon Straits. These colourful bits consist of electrical parts such as dimmers, motors and pressure sensors that snap together like magnets. I use them to teach Luke about technology."
