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. […]

Flashlight comparison – Dimmable Triple XM-L2 vs USB rechargeable XPL HI (WHL #74)

China gadgets, finally :cool:

Both of these have been laying around for years now. Time for a review – we currently got a little bit of a snowy April, but mosquito season has already started and four of those bastards have made it inside my living room. No survivors :twisted: And of course, those flashlights can also be used for, you know, flashlight stuff. Finding things, not tripping over other things, sitting around with empty batteries and so on…

So, the contenders:

“Roxane X6 XPL HI 1850LM 650m Type-C Rechargeable LED Flashlight IPX7 Waterproof USB Charging 26650 Powerful Searchlight – Cool White”, bought from Banggood almost two years ago at 25,56€ including shipping. […]

3 Speeds Electric Rotating Display Stand Mirror 360 Degree Turntable Jewelry Holder Battery for Photography Video Shooting Props (WHL #62)

We haven’t had a stock product presentation for a while, so why not start 2021 with something new from China… [bitter 2020 stares from the crowd]

Well, for the PCB Tree I figured a 360° view would be nice. I know it does have some ugly holes, but every naturally grown tree has these. Why not get something that not only offers a spinning platter for stop-motion tricks, but instead rotates something on display on its own?

Bought on AliExpress on 12th of December, 8.73€ including shipping, delivered on January 8th – that was a quick one! […]

A beefy electronic load (#P4F2)

Hello again!

I’ve been asked: What do you do with this electronic load thing? Well, I‘ve been using it as a battery torture device, what else could you do with a variable resistance device…

For a crude first step in actually testing my unit and also classifying a newly harvested set of deeply discharged 18650 cells, I slapped together some minimalistic Arduino program and hooked the thing up in parallel to the battery under test. The electronic load was set to 2 Amps with another battery, which was monitored by the Uni-T 203A current clamp. […]

10Pcs Electric Car Bike Toy Battery 18650 Spacer Radiating Holder Bracket Black (WHL #22)

…and 10PC 18650 Battery 4×5 Cell Spacer Radiating Shell Plastic Holder Bracket KT0569 as well (yeah, the second one is misleading, I know).

Today, I have some mechanical parts in preparation for another project. These are stackable 18650 battery holders without electrical contacts. I have some more holders for pure storage and also single (non-stackable) battery holders with contacts, but these are something in between.

Let’s have a look:

I actually ordered two variants of them, and as usual, a seller that has the one type doesn’t have the other in stock and vice versa – or they are super expensive. […]

Portable Powerbank Power Bank USB 1x 18650 Battery Charger Case Box for Mobile Phone MP3 (WHL #1)

Hey there!
It’s been a while and I was busy buying some gear…and getting some mail ;) Now I have a decent camera ready (for almost 4 hours at the time of writing! :D ) and this is gonna be the first shot on Wan Hung Lo products. My light box is not ready yet, it still lacks light – box is complete ;) , so you’ll notice my lighting and camera setup still needs some improvement. Well, that’ll come with time.

So, I had five single-cell powerbanks ready that I bought from AliExpress. Cost per unit with free shipping was 1,01€ (bulk I guess), current price is 1,05€ single or 0,98€ for bulk orders of 5+ units. […]
