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.

Surprisingly amazing chair!
Color: Pink, Color: Pink
tl;dr: If you need a chair that has the features of this one, then this one is a winner! Hits above its weight class for sure. My wife is 5’. She’s small. For whatever reason she ended up with a chair made for big people, like 6+ feet and up to 500lbs type of a chair. She’d often even sleep on it and chill on it. The chair was big enough to fit 2 of her to be honest. It was an expensive chair that I won at some raffle and didn’t like myself. Over the years it ripped (got a cover for it) and even started to get lopsided (from the sleeping) and finally a spring broke (hence the pillow on it in the pictures) She obviously lives pink. I also wanted to get a chair where she could work and not end ip asleep on. Not like we have a couch or a bed for that 😂. This chair is very obviously smaller than her previous chair, it’s also significantly cheaper in price and build, it’s also not as durable feeling or stable, and it’s just not as padded. Yet somehow it’s an amazing chair that we both like better than her previous chair??? Like it’s crazy that this chair somehow works better in so many ways. Her desk is modified to be shorter than normal desks (again, she small lol) and her previous chair was just too big. The wheels are also like SUPER smooth, like you can run a chair race easily with it. It rolls over her rug and tucks into her desk (which is in our bedroom) easily. The amount of space this has save us when the chair isn’t being used is a lot. Previous chair was much bigger and didn’t tuck in at all. The color is nice and the padding is plenty for a small and much lighter than 500lbs woman. I’m 6 feet and 200 lbs and the chair is nice for me as well. My chair is bigger and more secure in the backing, which is similar to this one. The lowest tension setting on my chair is still too high for her to lean back on my chair. This chair has a lower tension minimum and she can easily lean back freely, as well as keep enough tension to work without sagging. This chair is surprisingly outstanding! I’m sure my wife will destroy it quicker than the last one, but it’s so cheap that even if it only lasts 1-3 years, I’ll happily buy it ones or twice more 🤷🏽‍♀️. Maybe by then they’ll invent a comfortable titanium chair that’s affordable that she won’t destroy 😂.

Mid.
Color: Light Purple
The chair is fine, and reasonably easy to put together. However, I've been using it for a little over a year and a half, and it's already falling apart. Random parts of it have fallen off, which is fine because it was still functional. But now the most frustrating part is that the wheels continue to pop off, and while the first attempts to pop them back on worked, they will not stay on now. This is obviously greatly impacting the stability, and I will need to purchase a replacement soon. For this price and lack of long-term durability, I would not buy again.

Alexa messed me up, but the company of the chair made it right!
Color: Light Purple, Color: Light Purple
I wanted something small with arms that moved out of the way when I wanted to slide my chair all the way into my desk for more space. This fit the bill. I loved the color blue and I had that in my cart for a bit. One day Alexa mentioned that an item that was in my cart was on sale. It was the chair. I let it be ordered. When it came it didn't exactly look blue to me. But I kept putting it together thinking maybe it was the lighting in the room I was assembling it in. I brought it to my craft room and lo and behold it is light purple. I looked at my order and sure enough it said light purple. Boo! I looked in my saved cart and the chair was gone. So I accepted it for an error. The next day I checked to see if I could return it. Thought I could, till I read that I would have to pay to return it. So I wrote the seller to tell them to ignore the return. And that was that. Till a couple days later I get an email from the seller asking if I would like a full refund or a replacement at no cost. I was like heck yeah send me the blue one. I was thrilled and I wanted to thank the seller for doing this without the return of the other chair. But I could not find a place to do that now. So here is where I will thank you. Thank you so much for doing this for me. You guys are AWESOME!. I love the chair and I love the blue color. I find it very comfortable, lite, easy to adjust, the size works great for me, and for the price the quality fits my needs. I do hope it lasts me for quite some time. Thanks again!

Awesome chair definitely recommend
Color: Blue, Color: Blue
It was amazing the color was spot on and it was very very easy to put together and the size is amazing for my 11 year old daughter maybe not for an older person it doesn’t recline as much as it says so if you want a reclining chair maybe I don’t recommend this chair but the quality is amazing and the adjustment capability is incredible the noise level is at 0 it is an amazing chair we just got it so I don’t know so much about the dupability so if you want this chair for a child or a tween maybe even a teen easy to put together beautiful blue color this is the chair for you.
