CATALINBREAD KNIGHT SCHOOL SYNTH - DIY KIT DIYIf you want to get your hands on a Knight School Synth, we're offering them fully in kit form if you fancy building one yourself. Assembly is very straightforward and requires only a soldering iron, some solder, and proper ventilation, we'll take care of the rest. Here's a tale from the annals of my personal DIY history: I learned how to breadboard and read schematics right before college, and I breadboarded many designs posted on ampage. org. Shortly
If you want to get your hands on a Knight School Synth, we're offering them fully in kit form if you fancy building one yourself. Assembly is very straightforward and requires only a soldering iron, some solder, and proper ventilation, we'll take care of the rest. Here's a tale from the annals of my personal DIY history: I learned how to breadboard and read schematics right before college, and I breadboarded many designs posted on ampage.org. Shortly after that, I found a new DIY website. This one was called Beavis Audio. If you're familiar with this, it's for a good reason, BA was one of the premier DIY sites out there, and it refreshingly wrote everything in plain English. One of the projects there was called the Heterodyne Peyote Space Explorer". This introduced me to the CD40106 chip and I played around with that device for what seemed like double-digit hours when I was taking EE classes. One thing I stumbled across was when I combined a boost circuit I was working on with the 40106. It made an oddball noise, but one I thought could be cool with some refinement. It took a lot of tinkering, but it worked much better when I put a second boost circuit in front of it. I couldn't really explain why, but it sounded cool, and I built a couple for my friends. Some time later, I stumbled across a webpage authored by one Tim Escobedo. There's a ton of good info on his "Circuit Snippets" page, and it still exists today. As it turns out, Mr. Escobedo discovered a form of this circuit back in 2002, and comparing his circuit analysis with mine and the Space Explorer was a real "Eureka" moment for me. Our Knight School Synth is our most ambitious project to date. I've since leaned into Mr. Escobedo's method for producing the pre-gain, as it's simpler and uses far fewer parts than my original. Essentially, it turns your guitar signal into a square wave, and then uses the CD40106 to vary the pulse width of that square wave. There's also a switchable LFO, which automatically varies the pulse width for you, along with a Depth control to change the intensity of the shaping. It's a truly cool effect that emulates the monophonic synthesizers of yesteryear. Dare I say there's not a lot on the market these days that sounds like this! Controls - Rate: Speed at which the LFO automatically varies the pulse width. - LFO switch: Turns the LFO on and off. - Volume: Output level. - Depth: Intensity of the LFO. - Pulse: Takes your square-wave guitar signal and changes the width of the "on" square wave. Power supply The Knight School Synth only accepts a center-negative DC power supply capable of supplying 9 volts and at least 0,5mA of current (over is fine). DIY Kit information The circuit board has everything labeled as to what part goes where. You'll find the below image very helpful to identify what parts are what. There's also a video below showing you how the process will go. "Controls:
Volume, rate, lfo, depth, pulse.

poli glow shine
its works great .when applying more coats the shinier it gets
i used on several old boats because
the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is
How long it will last?
What will it look like after it rains?
Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.

Wish I Had Used This Sooner – Stop Debating and Just Buy It!
Wish I Had Used This Sooner – Stop Debating and Just Buy It!
After a lot of debate, extensive research, and way too many hours spent buffing my RV with other products that never fully delivered the results I was after, I finally tried Poli Glow—and I am extremely happy I did. My only regret is not using it sooner instead of letting other people's opinions talk me out of it.
The difference in how my RV looks after applying Poli Glow is genuinely impressive. The high-gloss finish it lays down on the fiberglass is deep, clean, and long-lasting in a way that the other products I tried simply could not match. The application process with the included mitt is straightforward and far less labor-intensive than traditional buffing and polishing methods, which alone makes it worth switching to. The hydrophobic properties mean water beads and rolls off beautifully, and knowing the UV protection is working to shield the fiberglass from the relentless Las Vegas sun gives real peace of mind for long-term appearance and protection.
For anyone who has been going back and forth on whether to try Poli Glow or sticking with whatever you've been using—stop debating, stop listening to everyone else's opinion, and just try it. The results speak for themselves and I won't be using anything else on my RV going forward. Highest possible recommendation.
