Commodore 64 C2N Tape Deck Repairs
Installed new belts in my #Commodore #C2N and now the tape appears to move at an even speed.
When I try a tape, it can actually find the header with the name of the file but fails to load with a data error.
I've tried to use the azimuth aligning software, but I'm not 100% it should look like to be correct. There are videos but they aren't super clear.
It's possible the pinch roller is also too smooth and hard too...
Just opened up my 40 year old #Commodore #C2N to replace the belts.
The inside is rather dirty, full of hair and black sticky grease. I suspect the hair may be that of my long departed Labrador - her hair got everywhere when I was growing up.
Congratulations to our PhD student Sarra Salhi for publishing her great work on polarization insensitive surface grating couplers!💡🧪

Optical antennas are key components of an optical phased array system, enabling light coupling between the chip and the free space. In such systems, surface gratings are commonly used as antenna elements, which however suffer from a strong polarization sensitivity of their scattering angle and efficiency. Here, we propose a versatile approach to realize micro antennas based on surface gratings with a polarization insensitive behavior exploiting a subwavelength metamaterial in the silicon-on-insulator platform. In the experimental demonstration, the antenna successfully achieves the same diffraction angle of 10° for both TE and TM polarizations and an estimated scattering efficiency of -4 dB despite a very compact footprint of 6.4 $$\mu m$$ x 2.9 $$\mu m$$ . The difference in diffraction efficiency between the two polarizations remains smaller than 1 dB over a bandwidth of 31 nm.

Looks like I need new belts for my C2N, after trying the azimuth alignment software out and carefully watching the tape speed wobble all over the place...!
What is the cassette player that we are going to connect to our CBM128?
