Temperature monitoring solution based on Raspberry Pi

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 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.

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
