In this video I do the seventh Maxitronix 10in1 Electronic Project Lab project: Wireless Continuous Wave Transmitter.

While conducting this experiment I made some notes over here: Maxitronix/10in1/7.

I made a bunch of mistakes while building and testing this circuit, and a lot of the footage I took didn’t make it into the final video. In particular in between the construction part of the video at the beginning, and the testing part of the video at the end, I added a ceramic capacitor at the base of the transistor; I hadn’t understood the instructions to install this capacitor as it wasn’t wired in using spring terminals like all the other components.

In this video I do the fifth Maxitronix 10in1 Electronic Project Lab project: 1-Transistor Radio.

This is the second radio circuit and just like the previous radio circuit I wasn’t able to make this one work either! But at least this time I did get some static noise out of the circuit, which was better than the “nothing” which I got out of the previous circuit.

Also, I did learn how to setup a frequency measurement on my oscilloscope: Measure -> Add -> Freq. Easy peasy! :)

Standard Aussie home television aerial RF coaxial connector

Man I had a lot of trouble figuring out what these things are called. I can tell you that they are not called F-Type, BNC, SMA, N-Type, or PL-259 connectors. In the I end I asked about this and learned these connectors are called Belling-Lee connectors, also known as IEC 169-2 Female/Male. But if you search for “IEC connector” (which these things are apparently sometimes called) you will only find the power adapters, not these aerial connectors.

New computer ‘trail’

I have built a new computer ‘trail‘ out of my old workstation ‘tradition‘. I was able to do this because I migrated the VirtualBox VMs that were running on ‘tradition’ over to QEMU/KVM VMs now running on ‘lore‘.

My new computer ‘trail’ is setup as the recording workstation for the “booth” in my studio. This is good because now I can record at 4K in the booth!

I don’t use Windows much these days but this new studio workstation runs Windows 11 Pro. I haven’t used software RAID on Windows before but for this workstation I setup a RAID1 mirror using 2x 2TB NVMe drives. I was able to configure the block size for the NTFS file system so I picked 2MB (which was the maximum) as this RAID array will only be for storing video recordings (which are huge files).

Oh cringe

Man. So. Today, this happened. I was watching a new video from Adrian Black and his EEVBlog multimeter failed:

It's disappointing that it's already failed

I have been saving my pennies and planning to buy an EEVBlog 121GW Multimeter because a lot of the makers around the interwebs have one as a nod to Dave Jones over on the EEVBlog, but that’s just so embarrassing that it’s failing. Of all the equipment you have you need to trust your test equipment the most and this is… well, just sad I guess.

Logic Analyzer with 1GHz Sampling Rate

Today I was pleased to discover this: DreamSourceLab DSLogic U3Pro32 USB-Based Logic Analyzer with 1GHz Sampling Rate, 2Gbits Memory, USB 3.0 Interface, 32 Channels.

There are some notes from the manufacturer over here: DSLogic Series USB-based Logic Analyzer.

It’s a logic analyzer which can operate at 1GHz that’s within my price range. I’m not rushing off to buy this thing, but it is certainly on my list.

The only other thing I have seen that compares to this logic analyzer is this RIGOL DS70304/DS70504– Digital Oscilloscope 3GHz/5GHz 4 Channel 20GSa/s 2Gpts 1000000 wfms/s which is roughly two orders of magnitude more expensive.
