My house is heated by an ancient ground source heat pump that every now and then has had various problems. Being a 40-year-old piece of equipment, it doesn’t have any of the electronics that all the new heat pumps come with. Since getting data about the operation of the pump is always useful when trying… Continue reading Temperature monitoring solution based on Raspberry Pi

Fallout Pip-Boy 2000 Mk.I replica – Part 5: Electronics and software
The Pip-boy project has finally been finished, after a bit of a hiatus. The last things that needed doing were finalizing the electronics, and writing the software. My original plan was to just use a Raspberry Pi to power the whole thing, but it turned out that dealing with the inputs from the physical buttons… Continue reading Fallout Pip-Boy 2000 Mk.I replica – Part 5: Electronics and software
Fallout 1/2 style Pip-Boy 2000 replica – Part 2: More design
I’ve added some more detail. Now I think this is getting to stage where there will be no more major changes, and where the next prints will the final pieces.
Fallout 1/2 style Pip-Boy 2000 replica – Part 1: Design
Here’s another one of my projects that has been on the back burner for quite a while: A replica Pip-Boy 2000, as originally seen in Fallout 1, Fallout 2 and Fallout Tactics (with minor differences). I’m designing the prop in Blender, and mostly 3d-printing the parts. The Pip-Boy will be powered by a Raspberry Pi… Continue reading Fallout 1/2 style Pip-Boy 2000 replica – Part 1: Design
RetroPi briefcase
Here’s a quick build I just finished: A Raspberry Pi running RetroPi, installed in a Makita powerdrill briefcase with a 7″ TV and four USB controllers. Also included are all the components necessary to power the whole setup: A 12V PSU that powers the TV, and a 12V to 5V voltage regulator that powers the… Continue reading RetroPi briefcase
Obi-Wan Kenobi’s flashlightsaber
I happened to find this 3D-printable model of Obi-Wan Kenobi’s lightsaber, so I decided to see if me and my 3D-printer were up to the task. There’s also an article about designing the lightsaber model in the Ultimaker blog.
Improved resistor value calculator
The resistor value calculator originally published here now supports 5-band resistors as well as 4-band ones. Also, larger ohm values are now shown with “k” and “M” suffixes. Improved resistor value calculator.
Hacking the Xbox – epub version
After finishing Cory Doctorow’s Little Brother, I was going through the “suggested reading” section at the back of the book. A title called “Hacking the Xbox – An introduction to reverse engineering” caught my eye, and I decided to see if there was an ebook available. Sure enough, the book had been released by the… Continue reading Hacking the Xbox – epub version
Nintendo NES RF-module removal
I was looking for a broken NES so I could use its case for a project I’ve been thinking about. I found one on eBay at a reasonable price, so I bought it. Once I got the unit, I found out that it had the infamous “flashing red LED” problem, which was easily remedied by… Continue reading Nintendo NES RF-module removal
Resistor tools
I just wrote a parallel resistor value calculator, and a resistor colour code calculator. There are lots of them on the web, but most of them seem to have a 1990’s era user interface, where you need to enter values into separate fields and then click on the “Calculate!” button. Blech. So, I rolled my… Continue reading Resistor tools
