Bosch Gourmet 8400 oven mode selector switch repair (Dreefs 4-DPS/260) (#P31)

A long, tedious blog post for today. This has been in the making for about 9 weeks and I’ve been looking for parts for another year or two. Pictures have been taken on multiple occasions in multiple locations, so it’s a hotchpotch that somewhat reflects the process. This is the use case for the 3D model generation of the WHL #61 post.

Our Bosch Gourmet 8400 microwave and baking oven has been there for as long as I can remember. It’s a huge and darn heavy thing for a microwave oven (27l volume!), and rather small for a baking oven with grill (broiler) functionality. […]

Oral-B toothbrush stand generation upgrade (#P22)

After just eleven years of excellent service, my Oral-B 25.526.3/”9500 Triumph” electric toothbrush died from mechanical failure – the gears went a bit toothless (oh the irony), so while vibration was still on, it wouldn’t rotate the brush. I did exchange the NiCd battery some years ago, but the drive cannot be disassembled, so that was a total loss. Meh.
At the time I spent 70€ and this model was on the higher end of the Oral-B product line. 11 years later even the cheapest models are lithium battery based and I would expect essential technology has trickled down to the base models. […]

3D models now available on thingiverse (#E12)

Quick note mixed with a bit of a “this is stupid” rant – as there’s quite a bit of 3D models coming in the near future (say…1.5 meters of them), I decided to put that stuff on thingiverse as well. It’s still hosted and linked here on this blog, but having it duplicated on an easy-to-search platform like thingiverse might be helpful for people with limited Google-fu. It’s also a nice source of somewhat standardized renderings from those parts, which I exploited in the previous post already.

Now to the “stupid! […]

DIY USB Micro panel mount connector (#P13F1)

Oh yeah, that has been sitting around for a while…

Back in June there was a post about two connectors (#P13), and there was one more similar item that just happened to be printed a few days after that post. As far as I can tell, I never made a separate blog post about it.

Well, as there’s another short post coming later today, here’s that little item as a double whammy for today. The USB Micro-B panel mount bracket thingy.

Unsurprisingly it’s closely related to the regular USB-A panel mount case, just a little bit smaller to fit the female end of a USB Micro-to-Micro extension cord. […]

MikroTik wAP ac door jamb bracket (#P16)


When upgrading my laptop to the QCA9880 3x3ac card, I had the need for an 3x3ac access point. I went for the MikroTik wAP ac at the time, my first dedicated AP, as I always was a FritzBox AIO dude. In the card review I said I wasn’t planning on in-depth reviewing the AP, but I still need to scratch a little on the surface here, literally.

The AP is sitting next to the excellent FritzBox 7362SL and in fact is sharing the power supply with it. As the MikroTik is a PoE device, it doesn’t have a fixed input voltage; instead, it’s a 11-57 V wide input (“12W max”). […]

HP 6644A refurbishment – front panel, back protector (#P14F1)

Time to finish the HP 6644A revamp!

tl;dr for the last post: Here’s where I stopped refurbishment after cleaning and replacing caps and fan:

First off, those leads stick out quite a bit at the back as well. I can’t really say which diameter I used, judging from the yellow cable lugs these were 4mm² for the power lines and 1.5mm² (red lugs) for the sense lines. Apart from not fitting the old protector, that one already has seen some damage. Probably because it is so tiny…

So: Redesign. Twice, as the first version that closely resembled the original design had really flimsy legs that suffered the very same fate. […]

DIY USB and SATA panel mount connectors (#P13)

Next batch of connectors incoming! (yes, I’m onto something)

I bet most of you are familiar with USB panel mount connectors, which (I guess) are a by-product of the slot mounted USB ports of PC mainboards in the late 1990s, early 2000s. Back then, boards had none or few USB ports on their back I/O panel, but often one or two available via pin header. So people obviously needed some slot adapter for them, something like this:

If you slap on a different connector on the other end and omit the metal bracket, this is basically what you get these days when buying USB panel mount connectors. […]

Mellanox ConnectX-3 3D printed brackets (WHL #42F1)

Looks like I got a project out of the 10GbE card thing

I have to admit that I was wrong in that post – the 3D model of the bracket over at servethehome doesn’t entirely fit the ConnectX-3 MCX311A. It’s for the higher-end dual cards (that I knew) with QSFPs (that I didn’t check). These are larger in physical footprint, so the bracket does fit by chance, but there’s empty space towards the PCIe connector. Also, because of the dual port architecture, these have their second mounting point shifted up higher, which means the second mount doesn’t even meet the PCB. […]
