Server Upgraded to Raspberry Pi 3

Since December last year, both and had been running on my Raspberry Pi 2 Model B server. Recently the Raspberry Pi Foundation released their newest model, the Raspberry Pi 3 Model B, and I decided to grab one as a replacement.

The main differences are:

  • A 1.2GHz 64-bit quad-core ARMv8 CPU
  • 802.11n Wireless LAN
  • Bluetooth 4.1
  • Bluetooth Low Energy (BLE)

Of all the new features, I’m solely interested in the increased clock speed of the CPU. 300Mhz is a big jump – 25% faster than the Pi 2. Hopefully it will make the server more snappy when serving files, processing scripts, and performing daily backups.

The server is hard-wired into the network, so I’m looking forward to an update of raspi-config, the Pi configuration utility, that would allow Pi 3 users to disable the onboard wifi/bluetooth radios. I have no use for them and would prefer to reduce the RF noise near to my home studio.

I’ve noticed it runs a little hotter than the Pi 2, and I have it contained in a metal case. I’ll update the site if there are any cooling issues to be concerned about.

Arduino Project: Hermes

Speed! Cunning! Moving freely between the worlds of the mortal and divine!

Okay, not the kind of language that leaps to mind when we’re talking about Arduino and homemade robots, but I had to choose a cool name for my Arduino-powered vehicle. The Greek gods had awesome names, and of all the gods that I know of, Hermes was the most…movey.

Not long after playing around with the parts included in the Osooyoo UNO kit I began to ponder how I could make something that could roam the house and pester my wife and daughter, so naturally motors and wheels became the order of the day.


The Arduino team have produced something called a Motor Shield. A “shield” is an add-on board that sits squarely above an Arduino board and passes through all of the digital and analog headers while providing additional functionality. By adding the Motor Shield to my UNO, I was able to easily attach the two 3V motors included with a Tamiya Double Gearbox which can be controlled via software.

Let’s play around with Arduino!


It’s Xmas time, and what better time to hole up inside and hack around with a fun “toy” like the Arduino? Tinkering is the name of the game, and this miniscule board affords budding electronics enthusiasts an inexpensive entry into the work of physical computing.
