Hewlett Packard HP 8018A Serial Data Generator

Posted on 2022-05-28 [Saturday] by Jay Jay

I saw this Hewlett Packard HP 8018A Serial Data Generator for sale for US $2,000 after having seen it mentioned over on Using a 1930 Teletype as a Linux Terminal. That sent me off trying to see if I could get my UTG962E from the UNI-T UTG900E series arbitrary function waveform generator to transmit a custom waveform. I managed to get the software installed on Windows and apparently I can upload any of *.sav, *.rec, *.dat, *.uwr, *.wfr, *.wf to my waveform generator, but I have no idea how to generate such files.

I’m watching Oscilloscopes for beginners and it mentions the OSC482 USB scope. Think I should get me one of those to play with.

Arduino project

Posted on 2022-03-09 [Wednesday] by Jay Jay

I’m trying to debug some Arduino code with my mate Aleksei, but I really need my new scope (which hasn’t arrived yet) so I can see what’s actually going on. I might circle back to this in the near future.

This was good fun: EEVblog #168 – How To Set Up An Electronics Lab. I think I ticked most of the boxes, but it did give me an idea of a few things I’m missing. But not for long! :)

Resistance is futile

Posted on 2022-03-07 [Monday] by Jay Jay

I was chatting with my mate CK about my resistor inventory. I’ve got two sets of shelves dedicated to resistors, and a folder with 50 resistors of pretty much every type possible at 1/4 watt and 1% precision.
