o2 DSL Router Premium disassembly/yellowing surprise (WHL #80)

I don’t often visit family, but when I do, my car is usually filled to the roof with old tech crap when I come back…and so is the apartment over the next couple of weeks, until everything is checked, repaired (if needed/viable) and subsequently stored, gifted, sold or binned.

Well, there’s this old o2 router (different labelling, I know…) back from the era where

a) internet providers were able to force you using their crappy loaner hardware (I did hack a similar unit back in the days, te-he-he),
b) those devices sometimes contained a WiFi module that was disabled by default but could be unlocked for a couple bucks per month (I never got why people do this over 24+ months instead of just buying a standalone AP), and
c) not sending back those miracles of NATted IPv4 tech at the end of your contract could easily cost you north of 100€, a ridiculous money-making scheme that was only stopped years later by court decisions that got delayed and appealed forever. […]


Dental Impression Mixing Dispensing Gun Universal Dispenser Gun 1:1 /1:2 Silicon Rubber Dispenser Gun 10:1 50ml Dentist Tools (WHL #59)

Some filler content (ha, pun intended) for THAT time of the year. I want my beloved winter back, and I want it to last all year round. Fuck that …intergluteal cleft sweat.

So what do we have today? A 2K epoxy dispenser gun. I bought this to test (and use) some 10 epoxy cartridges that randomly appeared at work – nobody uses this type, nobody even has a dispenser for it (we only have 2:1 and 4:1 glues, no 10:1), and it was expired like a year ago. As it is hard to justify buying an original dispenser gun for the extreme rip-off price of like 70€ for glue that is likely not even usable, I kindly disposed of the cartridges, bought the dispenser with my own money, and had a shot.

CITYSAX 160Ah LiFeYPO4 battery discharge and teardown (WHL #51)

Speaking of electric cars: A colleague recently bought a used electric car and (obviously!) contacted me in order to diagnose/troubleshoot it. Sadly he was able to sell it for a profit before we got it fully fixed, so no live data recordings, no power/torque graphs, no nothing to show here. But he left me a dead cell for which he got a replacement from the seller right away, as the traction battery had voltage dips under load that indicated (at least) one damaged cell.

If servicing individual battery cells sounds a bit strange for a modern electric car, that’s because we’re talking about a CITYSAX from a company that is conveniently named the same. […]


Kitchen Egg Timer Boiled Soft Hard Medium Color Changing Boiled Hourglass JAPAN (WHL #19)

Look, we’re steering off track…even fewer electronic parts than in the last slimy post! We’re back to the steam era!

I’m not planning to become an universal gadget tester, but I had to check this one which was in today’s mail. I got it from eBay merely two weeks ago and I paid 4.99 USD for it, including economy shipping. And now I’m a proud owner of some Nippon stamp worth 180 Yen, which in itself is around 1.5 USD. I didn’t buy on Ali this time because they only offer generic or German “Pearl” branded items (go figure). […]


Adroit High-Tech Magic Sticky Jelly Compound Super Clean Slimy Gel Computer PC Laptop (WHL #18)

After the hard facts of the last Wan Hung Lo post, let’s get a little softer, a little more slimy…and gross. You’ve been warned ;)

Today’s item is some cleaning gel that I bought at the end of January on AliExpress for 1.36€ including shipping. I’m not even sure how it is called, the package is mostly non-latin characters, but apparently it’s from “Super Clean Europe”…guess the Asian versions have more funky colorings added to them.

I cannot spot any weight, amount, volume marking on the bag, maybe the “80” on the bottom indicates 80g. […]
