The Long Road - Part 2 - (Stacked) Peltier Elements

3D Printing + The Long Road

Peltiers are interesting things. Inefficient interesting things.

Countdown to 2025 - #7 - Fixing a Mouse (and my Top 3 repair jobs)

Countdown + Datatalk + DIY

It takes money to replace broken stuff. I'd rather save some money by trying to repair it first. If possible.

Which isn't always possible, but at least I managed to repair this simple computer mouse. Which made me think what else I fixed over time?

Plate Lab - Glass Fiber based Building Plates - Part IV - Crap & Danger

3D Printing + Plate Lab

3240 can be anything. And stuff sold as FR4 can be outright crap.

So, there's the enterprising Chinese entrepreneur who sells very old FR4 on Amazon... It may once have qualified as FR4, but not today. These plates were old, ugly, damaged, full of scratches, and definitely contain formaldehyde, bromide, and probably tons of other halogens.

Moral of the story: made sure you know what and where you buy!

3D Smell... 3D Printing & Air Quality

3D Printing + Air Quality + Carbonmax + Filtermax

The smelly smell of smell...

Go watch this if you're into 3D Printing (and never considered the dangers): 3D printers are worse than I thought by Made With Layers. That's a good video on air pollution, possible dangerous particles, and gasses, when 3D Printing... (And he has a Fornuftig as well.)

Particles, PLA, PETG, VOC, HEPA, air quality and pollution, non-acid washed Activated Carbon... Things might be more complex than I once thought, and my 3D Printer might not be that harmless... Perhaps.

On an inspired side note:

I took the original Carbonmax and created my own (improved?) FilterMax.

Sunlu S1 Mod - First (real) ABS print on my Bambu X1C / Jupiter ABS Filament settings

3D Printing + Sunlu S1 Mod + ABS Filament

Time to go to bed, but first share an image of the bottom section, this time printed in ABS. The first attempt warped a bit, but the second try was a lot better.

Ikea Fornuftig + 3D Printer

3D Printing + Air Quality + Ikea

In the past I used a Dremel 3D20, and when printing PLA the whole room started to smell... which can't be good. These days I am the proud owner of a Bambu Lab X1C, and I plan to print ABS and PETG, and the one little test print I made smells, even though the X1C has a filter inside the enclosure.

Is that dangerous?

Replace Head Unit in an MX-5 NC2 (2011) - 1. Parts Required

Car + MX-5 + Atoto Head Unit

The MX-5 is a great car, but the radio Mazda put in isn't very impressive. So I decided to replace mine.

Here are some notes for those trying to do the same thing... I will add some images that identify some of the things that weren't entirely clear in the videos. Let's start with getting the right parts.

Right-sizing a home-server PSU

Datatalk

I am running a small, Windows 7 based home-server in my home. Its primary function is to serve music to my Squeezebox music player(s), but it also serves as my file server and movie transcoder.

I needed to replace the PSU, but what is a proper size?
