@darinhitchings7104 11 месяцев назад

I highly recommend the book Getting Started in Electronics by Forest E Mims III. I got started on it when I was 10 or 11. It's an excellent book for someone getting started. And it gives intuition without bogging you down in equations. From there, the next thing you want to do is either a) get an oscilloscope for $500 or else b) learn how to use the program PSPICE to simulate circuits (it's free).

You've done a good job although I can see how some people might get confused. The trouble is you'd need to visually show things like an induced magnetic field and electrons moving as that field collapses. And if you're going to go into that level of detail it's going to be a lot of work and make for a long episode. But none the less thanks for a really interesting video.

I'd love to see more circuit calculations. Maybe not in the video, but a link to something like a google document, with documentation on what to change and by how much for varied results. Like what you talked about with the antennae's capacitance vs the variable capacitor. What changes can we make to the variable capacitor, and what will those changes do to the resulting Rf?

Since I couldn’t find the parts-list I went through the whole diagram and captured every component I saw. I don't know if anybody is still interested in this, but here’s what I got (this doesn’t include the parts for the audio amplifier): Resistors: - 2x 100 Ohm - 2x 470 Ohm - 2x 8.2 kOhm - 1x 2.2 kOhm Capacitors: - 3x 10µF - 4x 1.5nF - 2x 3.3pF - 2x 150pF Other needed Components: - 1x Antenna - 2x 1mH Inductors - 3x JFETs (as it was mentioned in the video, he used the TiS58) - 1x Variable Capacitor 4-50 pF - 1x audio Jack - Power Source I do not guarantee that everything in this list is correct, I gave my best, but feedback is always appreciated!

I have always wanted to build my own theremin! Sooooo coool! I also saw your video on combining a plasma ball and theremin. Way cooler than just the LED lights I was going to settle for. I have an idea for an interactive artwork for an exhibit next January and I wanted to figure out how I could incorporate light and sound. This and the diy plasma globe will be perfect! Now I just have to figure out where to buy/ thrift all the parts I’m going to need and how to set them up inside my sculpture safely. I have a small old guitar amp to use for audio out. I want to make 12 small plasma globes and each one of them playing a different frequency so I can try to tune them to the 12 notes and halftones in an octave. I wonder how the circuitry for this will look and how complex that will make it. Thankfully my partner is an audio engineer and can help me out with some of the build and calculations.

@kingslayer9097 6 лет назад

@Willam_J 6 лет назад

A cheap and dirty way to make a small variable capacitor is to twist some small wires (like solid cat 5 cable wires) together. You can change the capacitance by twisting and untwisting the wires. For the value you specified, two lengths about 3-4 inches long would be a good place to start.

Good stuff as always. I was wondering if you could do a whole video on the best old electronics to salvage and how to safely salvage components from them. I am a hobby DIY electric guy, who lives in poverty and doesn't have a dime to spare on parts. It would be helpful when i'm at a goodwill/thriftstore to know what electronic devices have the most useful components and how to remove them without breaking them. Thanks! also, are you going to college this fall? and if yes, is it for electrical engineering? i sure hope so cause we need people like you!

5:00 That Epsilon in the formula is not the dielectric constant, but the permittivity, and that equals with the dielectric constant times the vacuum permittivity which is round about 8,9 * 10^-12 Q/Vm, so according to that you will get a capacity round about 10¹¹ times lower than with your explaination. Really interesting project though👍

Y'know, it's funny. I was made fun of for most of my life growing up for being right handed, and wearing my watch on my right hand. I thought nothing of it, of course. After all, I'm right handed, so it would make sense for my watch to be on my right hand. No. Apparently my watch was always supposed to be on my left hand so I could "operate" it with my right. This never made sense to me, and I'm also the outside-of-the-box thinker among my peers, so it's refreshing to see you have a watch on your right hand (the hand you write with). Also, great tutorial. I typed all of this under the trance of a DIY Theremin.
