What is the difference between transistors and mosfets? Can one be used in the place of the other?

[cyberscann54]

Mosfets are transistors but they are not all the same most general purpose transistors are capable of acting as a switch which is what the circuit uses and is capable of detecting very small amounts of current to activate the switch an turn on the led. A similar circuit can be designed to use a mosfet but this one will not work for it the pin out on a mosfet is not the same nor is the power requirements. If you tell what kind of mosfets you have on hand I can design the circuit to use them.

I have a concern is it in anyway possible that this Level gage may produce a spark. Even the remotest possibility could be dangers. Have you tested this in a HHO environment like a bubbler to see if there is the remotest possibility that someone could get hurt. Love the design but I'm all about safety many people don't really understand just how dangers a liter of HHO is.

Great video I too wish that more people knew how to hold a camera still and the Lighting is important

I have run a few test to see if sparking is even possible and after multiple test it is not an issue even with the leads side by side or even an audio plug there is no chance of a spark. The circuits base current is very low the transistor must detect a connection before it boost the current up. The only way that this circuit could spark is if the power supply was pulsed. Its a DC powered circuit so that should not even be a possibility.

Tripods and a long arm desk lamp work great

This is only the beginning there is a lot more to come every circuit I show everyone how to make will have an Instructible Also I am starting with basic inexpensive circuits to use with your HHO Cell to advanced circuits. My plan is to do at least 2 or more a week so stay tuned.

Excellent video and a very useful circuit. I am connecting several of these up to an Arduino Uno that I'm using to control and datalog the HHO cell. Thanks for sharing!

It really works.. Thank you!!!

I dont have any mosfets, I just read some about them and from what i had gathered they operated a lot like transistors but wasnt sure

[pat1huey]

I wish more people would do videos like this...
