Finally figured out how to make these discharge in the thousands of volts. Keeping them oriented in a Delrin tube was the easy part. Silver solder paste and classic phone handset wire stripped did the trick. High temperature epoxy like what’s used to affix heatsinks then covered the six crystals I used. I spaced each crystal from the Delrin with glass beads from Michael’s. The epoxy seems to have lasted quite a while so far. 10kV rapping crystal!

is this compatible with Arduino?

I wonder how that would run off a 5v solar cell. Might make an okay pump display type of deal.

Any speed controller recomendation?

Why is it only 2.85 volts? That means you always need to connect multiple to be make use of it on 12v or 24v system. Would be nice to have only one together with a battery for example

I have a huge section of those in series to allow access to a geocache. It trips a solenoid to open the cache. Pretty cool indeed, I just checked, there’s 16 of them together.

Bought one of these (assembled version) to do a few quick tests with some GM tubes. It works well, but the output is a bit high. I measure around 550V which, especially combined with the fitted anode resistor of only 1MΩ, is a bit outside the specs for most tubes.

I Had 10 of those in my car. the neibors hated me

👍🏻👍🏻

I just received mine in the mail and it works great, just like in the video. I also made my own 3d printed case for it. I am surprised they don't include this with it since it only took me a couple hours to make one.

Cool

Nice, Good demo. From "old man" Gonna get me one..-Thanks

Cool idea! You could calculate the delta-time in events, invert the number to get a rate, and then feed a kalman filter to update the rate more often.

I didn't realize weed was so radioactive.

I still have 1 from 20 years ago

That's for the Edwards integrity

Do not worry the 220v shaded pole motor also exists

What is the name of this product, I want to buy

What is the reference of this potentiometer ? and where can i buy one ?

👍👍❤

How can you charge at night with no sun 😂

hello is there a way to put the lever back again, because mine did come off, and I cant use the switch

Hi just want to ask if this is similar to the ebike hall sensor? I have idea if i can bypas the wire to determine the hall sensor is not working. I mean the two wire shorted together bypass the sensor magnet (Red and Yellow wire)

Awesome

how much power does this motor produce?

is this support 2 extended displays ? or just merorr them I have m1 MacBook pro

Is there for 18650

Hello, I live in Turkey, I could not order this product from your site, can you send me a list of electronic circuits and circuit elements? Thanks

Fireflies are normally dark and pulse light, these LEDs do the opposite. Also, fireflies light up yellow, but these LEDs look like they're amber.

k

How does that work when there is no extra circuitry inside the LED?

is there a living firefly inside the LED?

I love your videos and your store. You find the most interesting things!

Nice!

Crap

I just bought but i cant open it

How do u open it?

You reckon this is the right wavelength to cure UV resins?

Black 'glass' portion might be porcelain

Looks like a combo of glass and metal. Be sure to use anode resistor for long life. I recommend 10 Megohms if you don't see any other recommended value. The protective cap comes off for measuring alpha. Do not touch the delicate mica window. Do not put tape over it. These are way more delicate than the Russian ones.

Will Electronic Goldmine be selling a compatible driver circuit for this GM tube?

I just bought a fan on digikey that says it’s 10mm height. I’m curious how well it works

i have a similar motor, that being the Mabuchi EG-510ED-2B2. the label is different and it is meant to spin counter clockwise instead of clockwise. it also uses 12 volts instead. if you need any more information about the Mabuchi EG-510ED-2B2, then ask me as i own one.

Is that a glass lens? Neat. Rare to see incandescent bulbs used for anything new these days.

Thank you so much i was trying to find this one for some time now❤

Great... That engineering room inspires...keep up the great work Sir .. Signed getting older

Ok?.... How about explaining to your audience the details of this Geiger-Müller tube?

Nice find! I have several of those that are a green version. I've had 'em for 40 years.
