For an upcoming experiment, I need to know how accurate my #Keithley 2400 is at nA outputs (God I absolutely love that box… 🥰), but I also wanted to see how well my 6.5digit GDM-9061 multimeter tagged along..

Enter the HP 3458A… 💪🏼😎

Connected them all in series and although the set point on the 2400 is a bit off from reality, it’s own current measurement is bang on. At 20nA 🤯😃 And the 9061 multimeter was in agreement as well, even at such low currents.

Ready for next step, stay tuned 😎😎

At the night of the legendary capacitor explosion we also hosted a BYOD Oscilloscope night, where ppl could bring their instruments and learn more about them, common pitfalls, how to do basic measurements, more advanced stuff, etc.

Surprisingly many electronics enthusiasts don’t have an oscilloscope, and even more surprising, many don’t really know how to use the instrument they have.

The evening opened many new doors to the participants - I think everyone were happy 😃

Suddenly a loud bang from the lab at the local #hamradio club ‼️ 💥🤯

Luckily nothing happened to the people in there, but I guess it’s safe to say that this vintage capacitor decided to quit its job 😂

Always wear safety glasses 🥽 when testing and troubleshooting #electronics, especially if it’s vintage gear where you have no knowledge of its state and health☝🏼

I bought a #Hamamatsu H7828 photomultiplier module, a ‘photon counter’. They’re insanely sensitive 😳

Seller knows what they’re dealing with and sealed it nicely in aluminum tape.

I left the tape mounted and put it in a box to screen the ambient light in my lab (which was already dimmed), then powered it on. It shows a ‘dark count’, noise that produces a certain level of ‘background’ pulses. Then I opened the box, just a little. And it’s visible!! 😳😳

A few photons, not many, still makes it to the detector, despite the aluminum tape sealing, it’s insanely sensitive 🤯🤯

I need to find a way to count the pulses and do some statistics on it, stay tuned for future experiments 🤓

The Pico Technology TC-08 is dated, but it’s still going strong 👍🏼 With the optional terminal board, the thermocouple channels can be used to log either voltages or 4-20mA (industrial current loop).

I’m logging the discharge curve of a 9V Alkaline battery, using an OP-AMP as a voltage divider/buffer, as the terminal board is limited to +/-5V.

The software is really easy to use and is supported on several OS 😃

There are many voltage loggers out there, but if you already have a TC-08, the small terminal board is a really nice addition and an easy way to quickly log long-term measurements 🙂
