*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!) […]

3590S-2-103L 10K Ohm Rotary Wirewound Precision Potentiometer Pot 10 Turn vs genuine Bourns and Vishay pots (WHL #36)

Visiting the dark side of China today – product piracy.

First things first, I actually bought this item twice from two different sellers on AliExpress. One back in September for 1.07€ and now two more for 0.95€ each in early January, just to be able to kill one during inspection. The seller may be the same (I’ve seen that recently from BME280 sensors, review to come), but the shop name is different. It is intended as replacement for the current adjustment knob on my electronic load, as I am an idiot and during build I set the voltage over the pot not to the two end pins, but to one pin and the wiper.
