I’ve started to taking out from storage some of my electronic related tools to start on some personal projects. Lately, I’ve had the need to measure voltages and currents on USB devices and it’s a pain to setup circuits just to test them.

Buying an Android Phone in the Philippines

I’ve been an iPhone user for a while now. Been a while since I’ve purchased an Android mobile phone. I’ve decided to find a replacement for the old Sony Xperia smartphones I’ve been using. For starters, the smartphone needs to run on Android Marshmallow (6.x), has dual-SIM support, a fingerprint sensor and has a Bluetooth 4.x chip that has support for peripheral mode Android apps.
