Death and Taxes (#E3)

Well, not the Path of Exile map that screwed me over last week because animated weapons friggen fly above the ground and are entirely unaffected by my sparker build…no, it’s about the real taxes that are as certain and inevitable as death itself.

Apparently, it is that time of the year where the German tax authorities want the tax declaration for the last year, so I got to comply if I do not want to be fined. As this is my first real (required) filing, I need some time off to prepare the documents. I did one voluntarily for 2012 last December, but that’s not legally decided yet…5 months are indeed a very short amount of time to decide about a few thousand Euros spread across maybe 50 pages of paper :) But the mills of bureaucracy like to be fed well, and so I’ll pour in documents for tenfold that amount this time.

Müller Licht 5.5W/220-240V/50Hz/38mA/470lm/2700K/dimmable/E14 EB1500665 40036 (WHL #12F2)

Well, I guess I was onto something when I first complained about the failed E14 LED bulb back in WHL #12
Not only did the second one (out of four) die as shown in the followup #1, but now the third one is dead as well. And, which is my favourite part, the replacement for it was almost DOA as well. It blinks every few second and never fully turns on. What a heap of garbage!

So naturally I complained again ( :twisted: ) , and the guys from voelkner played the cheapest “shut up” card possible – they did a complete refund of the four initial light bulbs without any further questions asked. […]


About “wanhunglo”… (#E2)

Got a strange message to the moar@ address some time ago…still cannot decide what to do with it.

Dear President or CEO,
I am grateful for you checking this letter out. We are a Chinese domain registrar. Recently, we received the registration request from MCLK Global Ltd applying to register wanhunglo brand and domain names(cn hk etc), which have same main body as your company’s name. We send this letter to confirm with your company whether or not you authorize them to register those names. Please give me your thoughts ASAP so as to let us carry on, Thanks.

Breadboard friendly Four Decade Programmable Resistor Board, 1%, 1/4W, KIT (WHL #25)

Got some more Open Hardware today! Not mine, though…it’s a four decade resistor adapter from luftek, who apparently comes from Slovenia. He has a github repository for his project called Dekada if you want to check it out (literal git checkout is also possible :) ). I happened to buy Version 0.1 back in September 2016 for dirt-cheap 1.99 USD per unit – I bought two pieces via eBay, directly from luftek. Unlike the Wan Hung Lo guys, we in Europe generally have to pay a reasonable amount of money for postage…in this case 3.98 USD. […]


Luxury Wirst Watch Bluetooth Watch U8 Smartwatch Digital Sport Watches for Apple IOS Android phone Wearable Electronic Devices (WHL #24)

Dave Jones sometimes sniffs when he senses bullshit. I’ve got a strange sensation too, I feel a wank incoming…

Today’s item is something that I ordered for a friend. It cost 8.29€ on AliExpress (back in January 2017, and that was the second attempt), and I actually ordered two of them. What do you need two watches for? I don’t know. Probably for salvaging parts… ;)

I don’t usually refrain from buying something that might turn out crappy. After all, if it’s total bullshit, I can always ask for a refund and show some disintegration pictures to prove my claim. […]


Micro usb male to female 1 to 2 Splitter Phone sync data charge Cord Y Splitter (WHL #23)

Uuuh, I’m lazy today. Let’s review an USB cable :mrgreen:

Well, it’s not one of your standard A to B cables. It’s a splitter extension cable for Micro USB, basically violating all USB specs :cool: . I bought it as I’ve been using two phones in parallel for quite a while now – I can’t let go of my N900 with the nice QWERTZ hardware keyboard and full system access, but I’m also running a Galaxy S5 for all that modern Android rubbish (including BLE support for my GoFar). So this cable acts as a Y splitter from Micro USB (female) to two Micro USB males, effectively saving me the standby power (and socket space) of one charger. […]


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. […]


250W DC-DC Boost Converter Adjustable 10A Step Up Constant Current Power Supply Module Led Driver For Arduino (WHL #21)

What do you do when none of your existing power supplies can provide enough power for some decent LED module? Yeah, right, you buy a bigger one!

So I did. I had some 100W/150W DC-DC converters laying around, but most of them cap at around 36V. And with the very nice Toshiba E-Core 92W LED module that wants 40V or more, that’s just not good enough (same goes for the popular 25W/50W/100W LED modules!). So the new one in my collection is this:

Some more shots:

I bought it on AliExpress back in mid-January for 4.31€ including shipping. […]


Palladium LA-1000 pre-amp and Revox Evolution stereo system (#P2)

Well, this weekend I’ve been busy replacing dead and leaked caps from something not too Wan-Hung-Lo-ish…a Palladium LA-1000 pre-amp (“Vorverstärker”) back from the 80’s. These are still sold for absurd amounts of money (just like the Revox described down below), so I decided it’s worth a shot. Details on that thing are scarce, and so I’d like to post the cap list in case someone also needs replacements for their dripping electron containers.

USB 2.0 4-Port Aluminum Hubs … and Chinese manual labour (WHL #20)

Hey :)

For today’s blog post I have something that I found at work yesterday. It’s a plain old USB 2.0 hub in an aluminium case, which is used inside of our measuring equipment. Just a jellybean part, it’s sold as Logilink here but I bet other brands just slap on a different logo on the front and they’re good to go. We chose this because it is relatively small, has all USB jacks flat in line (the smaller ones have 2×2 configuration or tend to stack them), and can make use of external power supplies, rather than sucking too much from the uplink port.
