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.
(Speak Russian? Vlad translated this post!)
This Huami H3 smartphone cost me $34US (210RMB) in January. It’s sold with a 5 inch screen, Bluetooth, WiFi, 4G cell connectivity, Android 4.4 and an 8 core processor.
“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.
Earlier this month I was lucky enough to head over to Shenzhen, China, for Dangerous Prototypes’ Hacker Camp and Maker Faire Shenzhen. I flew over with Jon Oxer (from Freetronics), and Mitch Davis (from Hackvana) was on our flight as well. Good Melbourne contingent!
Ian from Dangerous Prototypes has put a great series of day-to-day blog posts up on the Hacker Camp mini-site explaining the full program, so I won’t bore you by repeating them. Needless to say he and Jin, and the other organisers, did an insanely great job of showing us all the things they love about living in Shenzhen. I want to highlight just a few things from the trip that stood out for me.

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.
