During the COVID-19 pandemic I started to exercise at home and bought some adjustable dumbbells. After a while I realized that I would not use the four 1 Kg weights I had bought, since I had also bought 2 Kg weights that were better suited […]

Changing my 3D models portfolio to Printables.com
Last year Prusa Printers became my favorite 3D model website for 3D printable files, being a huge upgrade when compared to Thingiverse. Now its name was changed to Printables by Josef Prusa. This is a good change in my opinion, since the previous name suggested […]
Bit Holder
I’ve designed and 3D printed a very simple bit holder. It’s capable of holding up to 30 bits, the exact number of bits that came with my screwdriver. It was designed in Fusion 360 and the 3D files are available on Thingiverse.
Inline switch for low voltage applications with 3D printed shroud
I needed small inline switches to control LED lights in my office. Since I had some round flashlight switches, I tried to fabricate a simple shroud that could be 3D printed, so that the switched could be used with wires, instead of a tube assembly, […]
The new hot-end and its fan shroud
Unexpectedly, my old hot-end stopped working. Badly clogged with a mix of hardened ABS and pieces of the degraded PTFE tube, there was no hope of using it for any longer. It was a 3.0 mm ceramic hot-end, ancient technology when compared to the new […]
Variable power supply from an old power brick and a buck converter
I had an old wireless router power supply (12 V, 1.5 A) that was unused and thought it would be nice to have a variable output voltage power supply. I achieved this by using a cheap DC-DC buck converter and a 20 K ohms potentiometer. […]
Projector wall mount
I designed a simple wall mount for my LG PH550G projector. It is angled at 10º and allows projecting the image on the ceiling, so that I can watch movies while lying on the bed. It’s a setup that I always wanted to try, because […]
Upcycling computer fans
The Vantec Tornado 92 mm fan was one of the most powerful fans used by computer hardware enthusiasts during the “Pentium 4 era”, in the early 2000’s. It draws 1 A at 12V spinning at 4800 RPM with a noise level of 55 dBA. I […]
Replacing the rubber grommets of a Corsair fan
I have four Corsair fans (SP120 and AF120) bought in 2014, that are still in use in my computer as of May 2020. They originally came with rubber grommets for vibration dampening and isolation, potentially reducing the fan’s noise. After 6 years most of these […]
