Macbook Bluetooth upgrade for LightBlue Bean

During last year's blackfriday sale I was introduced to the epic Lightblue Bean "Cheaper than a turkey" promotion. I grabbed two beans during a group buy spree. A week later's The AmpHour interview with Colin Karpfinger justifies that my purchase is not purely impulsive. However I did make a mistake. I was under the impression that a Mac … Continue reading Macbook Bluetooth upgrade for LightBlue Bean →

Singapore Mini Maker Faire 2014, from Visitor to Maker

Singapore Mini Maker Faire has entered into the 3rd year. Being at the right time (long weekend) and right location (community club), the turn out is overwhelming. Same overwhelming is the wide range of exhibits, which are far beyond what I can put into words. Giant cardboard structures have become the signature for almost all Singapore maker events. … Continue reading Singapore Mini Maker Faire 2014, from Visitor to Maker →

JTAG adapter for Arduino Micro

For the holiday season I get myself an AVR JTAGICE3. Holding the new shiny emulator and a bunch of Arduino boards, what shall I do? Of course to hop onto the all-hail Atmel Studio and ditch the toy-alike Arduino software. Reason being? Debugging Arduino code with serial console is no fun. I need my single … Continue reading JTAG adapter for Arduino Micro →

FT230X charger detection investigation

I bought some FT230X (FT230XS) USB-USART bridge chip recently for a new design. FT230X is not only cheaper than the traditional FT232RL, but also offers a new fancy "USB charger detection" function. This interests me because I'm quickly running out of desk space and power socket. I wish the new device to be solely powered by … Continue reading FT230X charger detection investigation →

This is the second year of the event and the venue was relocated from the remote (to me) Science Center to Singapore's busiest Orchard area. And it is free entry for all 😀 If anything would … Continue reading Singapore Mini Maker Faire, 2nd year →

Poorman’s OLED test jig

During last (Chinese) year end shopping frenzy I grabbed some OLED display panels, hoping to boost the presentation of my projects. The panel model is UG-2864ASGGG14, made by "WiseChip Semiconductor Inc." in Taiwan. Unlike typical LCD modules with complete interface board and 0.1 inch pitch pin headers, this is a bare panel comes with only the glass and … Continue reading Poorman’s OLED test jig →
