In Part 1 of “Inside a $34 Smartphone” we poked at the software side of the dirt cheap Huami H3 smartphone.
We now know the phone is a Spreadtrum SC6825 passing off as a MediaTek. Using fake branding that combines Huawei and Xiaomi into Huami – something less than either.
It’s possible to blacklist a single USB device from connecting to Linux, while allowing similar USB devices to connect. In my case, I wanted to disable my laptop’s built in Bluetooth host (a USB device installed inside the laptop).

I’ve been a bit lax with the blog updating. In Part 1 of this post I promised Part 2 “soon” and here it is, eight weeks later. Oops.
This two-post series, aimed at embedded device beginners, explains some differences between Arduino and Raspberry Pi. In this second part we’re going to focus on one particular issue – “real-time” constraints. We’ll also quickly look over some of the alternative devices available.
“If I can buy a Raspberry Pi so cheaply, why would I ever use an Arduino for an electronics project?”
I often hear this from people who are new to embedded programming and electronics. This post is the first of two, aimed at beginners in the embedded world. We’ll go over some of the differences between a typical Arduino and a Raspberry Pi, and the reasons you might want to use one or the other for a project.
Misappropriating discount store LEDs to improve the illumination in my microscope.
I’ve assembled a network installer image to install Debian 7.0 “Wheezy” on the GK802 “Android TV” Mini PC. This is intended for people who want to run the GK802 headless or semi-headless, for server or robotics applications.

Taking apart a very cheap USB to Ethernet adapter and pondering on the parts found inside.
Here are two USB to Ethernet adapters:
One of them is sold on ebay for $3.85 AU ($3.99 US), including postage to Australia. The other is sold at Apple Stores for $29.
At Make, Hack, Void we’ve had a Rep Rap Pro Huxley 3d printer since the beginning of the year.
Unfortunately we’ve also struggled with a couple of long-standing problems. Continue reading
Demo page with data from the last week in September
A few months ago, in the dead of Canberra winter, we discovered our flat had a mould problem. Insidious disgusting mould had crept in around our walls. Much scrubbing ensued.
