I have also bought a LED spectrum analyzer, very nice and impressive but certainly not suitable for professional use, but who cares!

The technical features are many and not very intuitive to be changed with just two buttons on the back.

However, I’ll summarize them very briefly:

• Automatic detection of Microphone or Audio Input (Jack 3.5).
• Ability to disable the clock.
• 12 display modes.
• 7 color modes.
• 84 display effects can be combined.
• 8 brightness modes.
• Clock adjustment.
• 4 time display modes.
• Alarm clock function.
• Custom RGB colors.
• USB 5v power supply.

Below are some photos of the inside.

The reset button is very curious can cannot be reached from the outside (missing the hole) and also a Micro USB connector unusable from the outside of the case.

I attach the datasheets of the integrated circuits that are used and the manual in English language that was sent to me via email, the one available by scanning the QR Code of the product is only Chinese :-D

Still in beta stage but interesting this software written by SLC that allows you to write and read C64 file formats (D64/G64) using a regular 360k Floppy Drive with the Greaseweazle interface.

To understand how this program works, you should first read the README found in the program archive.

I tried it personally and it works quite well, the only problem is the double sided management of Floppy Disks for Commodore 64, i don’t want to dwell too much on this question but in other words the Floppy Drive PCs do not allow you to turn the floppy disk to use also the other side of the Floppy Disk, the optical sensor is present only on the left side of the reader (the Floppy Drive of the Commodore 64 does not have this sensor).

There are MODs to get around this annoying problem, mods that are not exactly immediate and not for all Floppy Drive.

So let’s say it outspoken, if you want to read and write Floppy Disks for Commodore 64 what i recommend is the software OPENCBM + Hardware XUM (ZoomFloppy) or similar and a native Commodore 64 (1541/1541-II) drive. :-D … and everything is great.
