New kit

Posted on 2023-09-01 [Friday] by Jay Jay

I’ve installed my two new microscopes, the TOMLOV DM602 Pro which arrived today, and the Yizhan Microscope which arrived yesterday.

Using my new 8K 5-in 1-out HDMI 2.1 Switch I can put either of the microscopes on the top display. I can also put the Rigol MSO5074 scope and an Xbox on the top display. There is one spare HDMI port which is on the front of the device which I can use for ad hoc purposes.

Before the HDMI switch output runs into the top display (a Teac TV) it runs through a 4K Audio Video Capture Device which allows me to record the output for inclusion in my videos.

USB Hub Chain

Well. Turns out you can only chain up to five USB hubs. I know, because I tried to chain six. I feel like this is a life accomplishment, and it should unlock a secret level or something. After finding this limitation myself, ChatGPT confirmed it.

DC-580 buck-boost power supply with CH340N IC

So I have one of these FNIRSI DC-580 buck-boost power supplies. It seems to have an CH340N USB to TTL serial port IC attached via MicroUSB, so might like to figure out how I can program that.
