Improved OpenSCAD battery holder script (BigClive) (WHL #97)

A while back, BigClive used to share OpenSCAD snippets in a lot of his DIY videos, allowing viewers to print (and modify) things that he figured out for the specific video. One of those was the battery holder script, a simple array of square-packed cylinders that were hollowed out from one side, in order to, well, hold things like batteries, or hex bits, or screwdrivers, or …

I recently had the urge to store a bunch of batteries in a nice way and began modifying the simple 33-line script. Couple of viewers already suggested changes like center holes, and since OpenSCAD scripts are just plain text, they were able to share their modifications in the comment section. […]


Samsung CLX-6200FX series RTC battery replacement (#P41)

Tutorial time! We don’t have a tutorial category yet? Well, it’ll be a project then…

Let’s just skip all the YouTube tutorial BS with two-minute intros on volume 9001 and thanking their sponsors entirely, and get to the point:

You got a Samsung CLX-6200FX series printer (6220 and 6250 – probably also their predecessors 6200, 6210 and 6240) that wants you to set the date and time on every power cycle, and you’re fed up with it? Great, Samsung wasn’t a dick about servicing, so here’s what you need:

* One new CR2023 3V lithium primary cell
* A small Philips or flat head screwdriver
* An ESD strap or a grounded piece of metal nearby
* The damn printer
* Enough space to access the back of the printer (no need to lift it)
* Ten minutes of free time

Same procedure by the way for adding or replacing extended memory, see below for details. […]


CR2025/CR2032 battery dummy for power consumption tests and a hungry Supermicro board (#P21)

This bugged me for quite some time now: Ever since a very nice dumpster revealed a stripped Supermicro server chassis including a Supermicro X8DTL board (Dual-1366) to me, the BIOS battery of that system seemed to be empty all the time. You see, I use this machine as an offline backup, so once every couple of months I fire it up, transfer my data, and unplug it from power and ethernet. And almost always it doesn’t start right up because the CMOS data is gone. Ideally it should be a headless unit, so that’s highly inconvenient.

I finally got around to test this – the fix will be another project for some day in the future. […]
