*NEW*National Instruments NI GPIB-USB-HS Interface Adapter IEEE 488 Controller (WHL #87F1)

Well hello again, welcome to the famous “the internet is full of fake GPIB adapters” show! Today we got… *drum roll*…a fake National Instruments GPIB-USB-HS! Like last week, but different!

In all seriousness, after the recent experience with the fake adapter from Amazon (and NI’s reaction, or the lack thereof), I decided to buy one myself. After all, my HP 6644A power supply does offer HPIB/GPIB so I could maybe control it remotely and log data (with a Raspberry Pi?), plus likely any outcome of delivered goods would be suitable for a blog post. […]


Fake National Instruments GPIB-USB-HS converter (and NI not caring about it) (WHL #87)

Niche hardware again for today, a USB to GPIB/IEEE-488 converter from National Instruments. Or at least what the Chinese have deemed necessary for a functional copy…but first things first.

This adapter was bought at work for connecting an ancient beast of a scope (a LeCroy LC334 – 4 channel, 500MHz/2GSa/s, 400W, 20kg spread across 50 liters of chassis volume, 9″ 640×480 color CRT) to a modern computer. While that sounds crazy (well, it is), that old hulk was purchased with a current probe, which is actually very useful for a current (ha!) […]


Noname LED bike helmet autopsy (WHL #81)

Chinese junk that appeared on my work bench this week!

Well – it’s a bike helmet. An LED bike helmet. A colleague brought it over and asked if I could install an USB type-C port since he (or his wife?) brutally murdered the micro USB in the back. Sure, pinouts are basically identical and access to the thing is darn easy. Oh, no, they’re not.

Turns out this thing can be tossed, since he doesn’t want her to use a nonfunctional LED helmet that furthermore still has a ticking lithium time bomb in it. So I did, after extracting all the goodness shown below. […]


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! […]


Bosch Professional GAA 18V-24 USB charging adapter 1600A00J61 1600A00J5W (WHL #49)

Something out of the ordinary for today, a brand new item, bought for disassembly and kind-of off-label use. A Bosch Professional USB charger which happens to have a 12V port also…

Contrary to my very first thought when I found this charger, it does NOT allow 18V batteries to be charged from USB or a 12V source. Maybe I should test that, but I doubt it. However, it does convert the other way – stick in a 18V power tool battery (ranging from 1.5Ah to 12Ah as of today) and get a USB charger with a lot of oomph, or a “heated jacked” power source with a lot of potential for baggy pockets.

150W Welding Repair Tool Titanium Plating Lead-Free Solder Pot Adjustable Temperature Tin Furnace with EU plug (WHL #48)

What’s worse than lead-free solder? Lead doped lead-free solder… :roll:

Today’s item is a “500g” solder pot that I bought during the Christmas/annual leave shopping spree mid-December for 12.06 USD including shipping on AliExpress. Prices have even dropped a bit since then.

I’ve always been collecting residue from desoldering stuff as I want to minimize contaminating ordinary trash with lead. Not on a crazy level like the EU tries forcing us to, but if I can avoid PCBs and electronic components getting mixed with domestic waste, I’ll keep them separate. […]


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. […]
