I was in Barnes and Noble last week and was looking at their STEM educational kits. They had one that was an FM radio and said on the outside that you would learn how an FM radio works. But the kit consisted of a potentiometer, some wire, a speaker, a battery holder, and a circuit board with a blob of epoxy over the middle of it. Yep -- gonna really learn a lot from that hand-on project. the human body DC resistance is about 1..2MΩ but depending of moisture and oiliness it may come down to 3kΩ and go up to above 10MΩ

Explain the theory of operation behind your approach -- how does connecting the two ends by a very, very high resistance connection result in operation? SHOP NOW The unique blend of 100% natural Essential Oils has been carefully selected for purity and performance. say 1mm² : (200·π·17mm²) · (150-20)°C -- if the thermal resistance from case to ambient would be "0" but the datasheet - if one exists - may not give you time and ambient related safe operating conditions ... My theory behind what I think the operation should be is that when there is a very slight flow of current through the circuit (of children holding hands) it is sufficient to turn the 2N2222 BJT on and then the LED. Using just one BJT wasn't sufficient so I made a Darlington Pair to increase the current gain. My thinking is that the 2N2222 BJT won't stand 0.66A current which I want through the High Powered LED so the next best thing in my toolbox is the Mosfet.for the led to have high power (through the step up converter) the Li cell needs to provide even more power Very good service, prompt delivery and great product, the Octopus kite. An immediate hit with granddaughters aged 8 and 11. Easily launched the kite despite bad weather and little wind. ...

Connecting a capacitor (I would suggest about 100 nF.) in parallel with R6 in your modified circuit may solve the problem. https://www.addicore.com/TP4056-Charger-and-Protection-Module-p/ad310.htm Li-Ion Charge/Discharge Controller ( outp 3.7V ) SHOP NOW Essential Oils have once again become a main feature in modern living.

and NE coordinates the 200km error allowed? (i will attempt to scan the anomalies at the area ... the success would be quite unlikely but ńot impossible ) people are also unaware of "normal" = if your class thinks your strange you may loose your prestige ... worse - it may take one "schizo" parent to complain for you to loose your job ? SHOP NOW Sense of smell is our most powerful sense. Studies have shown that inhaling the aroma from various Essential Oils can stimulate an area of your brain called the limbic system, this is where emotions, behaviours, sense of smell, long term memory, heart rate & breathing are all controlled. Les, I will put your circuit together as soon as I get a chance and let you know how it goes. I think it looks great.

we can assume the ~AC impedance of the body is a lot lower - so , about using human as a wave guide.. (if you're not to test anything else) ..is likely a better idea if you can come up anything that may trigger their motivation to learn more about the subject - the weirdness of the experiment likely fall to a secondary option Provide opportunities for children to apply their growing knowledge by conducting simple investigations. For example, what happens when they add an extra motor, use a battery with a higher voltage, change the length of the wires etc.?
