Quadraphonic UTAU Cover

One of my hobbies is mixing music with computer generated voices. So far, I have started with UST files that other people have created. These files describe the length, pitch, and pronunciation of each note. I created this mix of Daisy Bell (Bicycle Built for Two) using UTAU software. Vocaloid is another type of software that is used for this, but it costs $500 for the base software plus $100 for each voice bank. So creating this song mix with Vocaloid would cost $900. Instead, I am using UTAU which is free with mostly free voice banks.

For this quadraphonic mix, I used four characters with different voices- Waltt, Ken Shippai, Alice 16,  and Daronavo Odalakian. I put one on each channel. Audacity only supports 2 channels, so I downloaded a new audio editor, OcenAudio, that supports plenty of channels. I set up the mix so that it sounds like a different character is singing from each corner of the room. This fully takes advantage of my speaker system.

Quadraphonic systems have largely been replaced by more advanced surround sound, so there isn't much quadraphonic music available to download. There's not even much surround sound music available, and it isn't supported by Youtube. If I upload my music to Youtube, it will be converted down to stereo (2-channel). If I put it on Google Drive instead, the integrity of the file is preserved. To get the full experience you must have a surround sound system (quadraphonic, 5.1, 7.1 etc.) You can download it or play it in newer browsers such as Chrome and Edge. Please ask before reposting.

Strip Sander Light

Several years ago, I got a glass-cutting bandsaw from my grandpa. He hadn't used it in several years, and unfortunately the blade broke the very first time we tried it. I tried to convert it to a regular bandsaw, but then I found out that the belt had rotted. It burned through a new belt, so I superglued it back together a few times. Then I tried some alternatives such as a vacuum cleaner gasket. Somewhere along the way, the regular saw blade broke. The glass cutting blade was at least $80 to replace, and the regular one was about $20. So it sat on the shelf for a while because I didn't want to keep spending more money on it. Finally, I decided to use a roll of cloth-backed sandpaper to convert it into a belt sander. I superglued the ends of the fabric together. It has held up quite well, completely wearing the sand off the cloth before the sanding strip breaks.

The next modification was mounting it to the workbench so it wouldn't shift around. I put it next to my drill press, and I was using the light from the drill press above. But this was awkward. So next, I decided to add a separate light to it. I used an led desk lamp from IKEA. They seem to only have a smaller USB version now. Here's an affiliate link to a similar one on Amazon:  https://amzn.to/2UoUmLg
To mount the light I drilled 2 quarter inch holes the right distance apart and made a quarter inch thick wooden spacer with the same hole pattern because the base from the original light was thicker than the sheet metal of the sander's box. Then I screwed the light in with some small machine screws. My dad suggested changing the switch. So then I found a toggle switch with an led. I drilled a half inch hole to mount the switch.
I installed an outlet inside the box of the strip sander so it wouldn't need an extra plug.

Quadraphonic Surround Speakers

I watched a video on quadraphonic sound. It's like the surround sound of the 1970s. Most surround sound systems these days are 5.1 or better.
I have collected a few too many speakers, so I decided to put another set to use. I already had two 4 ohm speakers on the sides of my computer monitor, and I decided to add two more on the other side of the room.
I purchased a 2x20W amplifier and installed it on the front speakers. The rear speakers are now using the old amplifier that used to be on the front speakers. The front speakers are used more so they needed a more efficient amplifier. the 2x20W class D doesn't need a heat sink. the 2x15 class A/B needs a heat sink and fan.
I used a 22 gauge 4 conductor wire running under the rug to the splitter box. I used an 18 gauge 2 conductor wire from the splitter box to the rear speakers. For the splitter "box" I used a section of wood from a peach tree with a 2 1/8 inch hole drilled in it.

I tested this setup with Minecraft. It was interesting to have the sounds of different Minecraft animals coming from different directions.  Hearing the ender dragon behind me was the most impressive.
