Update VMWare ESXi SSL certificate

Another post in the category: I keep reinventing the wheel (or: I keep forgetting how I did stuff in the past). Here's how to renew your ESXi SSL certificate.

Another "How to boot your Raspberry Pi from SSD"

This is another short one in the category: "I keep forgetting, so let's document it". This post contains the steps to make your Raspberry Pi boot from an external device like an SSD or HDD. It works on Raspbian (Debian) 12 (Bookworm). I haven't tested this on any other versions.

Wemos D1 Mini won't write?

Ok, this is a short one. On a few occasions when I'm trying to write a Wemos D1 Mini, no matter what I try, it won't write. Since I've "fixed" this on many occasion but I keep forgetting how I'm actually writing it down now so next time I won't have to scratch my head for so long. It's simple...

Andonstar AD208 battery compartment fix

For a long time I wondered why my Andonstar AD208 wouldn't keep time, even though I placed an 18650 battery in the battery compartment. If it couldn't do that, then what was even the use of the battery that could clearly be placed in the microscope?

Hack your Segway E110S / E110SE / E125S

We used to rent scooters from time to time because myself, the misses and the kids like to go for rides on sunny days. It didn't take long before we decided that keep renting scooters wasn't a viable option and that we should treat ourselves to our very own scooters.

The DIYMore 18650 Battery Shield V3 su... isn't very good.

Earlier this week I was working on a project where I wanted to power some electronics with an 18650 cell. Because I needed 5V and 3.3V and an 18650 doesn't provide either I dove into my grab stock and came out with one of the "DIYMORE" battery shields I had in stock, ordered on the cheap from AliExpress when I stumbled upon them one day. So I put an 18650 in, soldered the electronics to the 3.3V and 5V rails, checked if everything worked and went on my merry way.
