PWM for HEAVY LOADS!!! Simple Circuits.
I said blue goes to 24V, THAT'S "BLUE" CONNECTOR not wire. This circuit builds on one that we did in a previous video. Now we add power transistors (PNP or NPN) to drive heavy loads and higher voltages. You could also use FETS if you prefer working with them. This circuit works as a dimmer for LEDs as well. https://www.youtube.com/channel/UCQSsDr3RYfWqK65hLIkddEw

How to make a Chinese Flute - Step by Step.
This video number two in a series of flute making videos. How to make a Chinese Flute. This flute is unique because of the membrane that gives it that distinct sound. Look for my other videos South American Flute, Irish Tin Whistle, Transverse Flutes, Shakuhachi or Japanese flute, Native American Style flute etc. UPDATE - September 4th 2018: The best membrane material I came across is the plastic holder from a sanitary napkin, easy to install, unique sound and little adjustment.

Homemade Soldering Station with Solder Pot.
DIY soldering station with solder pot. This unit adjust the temperature of your solder iron, keeps the iron in a safe place and save solder. Generally solder flux is acidic and damages the solder iron tips but with a pot you could save your tips and reuse solder. To coat wires you have to use a lot of solder which is expensive these days but you could reuse all the waste solder in the pot. Be careful with this circuit. https://www.youtube.com/channel/UCQSsDr3RYfWqK65hLIkddEw

$1 Polarity Protection Circuit (PPC). Built for the Roland RMP - 5 but is ideal for any device.
This is a Polarity Protection Circuit. Wire the output to the polarity you need and use any adapter. With this circuit you don't have to look for the right adapter anymore . Even unrectified AC comes out with the right polarity. I built this for Roland RMP -5 because their adapter is overpriced. This unit is less than $1 but you could use it on any device. Pay attention to the output you need when wiring the output.
