What's the type of switch where the connector slash rotary disc can engage multiple throws at one time

I only have the red

Can this product be sent to Indonesia?

👍👍👍

Bro how much is input?

great

I usually see these with 2 of the 9w plug in fluorescent lights

Thank you for nice videos, I order a negative ion generator module 12VDC-4.5KV exactly like yours. I connected black prob of my Multimeter to ground and red prob to output of it. If I touch the side of the output wire, I see -120V but I will see an electric arc with more than -2KV if I close (not touch) to its tip (output wire) so that my multimeter shows error. Do you think it is normal ? I don't know why i see -120V if i touch the wire?!

hey mine isn't charging no matter what i plug it into

This box is a good value. I've bought two of these. You'll get a good assortment of Triacs and SCRs. Different case styles, voltage ratings, gate sensitivities. I can't find anything like it anywhere. All of mine tested good. I was able to find data sheets for all of these. They are great for repair or experimenting.

What type of power supply do you need?

Cool 👍

Humans can see 850nM, but it needs to be pretty bright. When you see that red dot, that's actually human infrared vision. I got some of the above LEDs for nightvision floods, but now lost in piles of junk (need to buy a couple more.) Human eyes: ...I found that I can just barely see a flashing green LED with 10Meg in series, current measured as 0.15 microamps, 1.47VDC so 220 nanowatts drive. For 880nM LED I used 10K in series, and could still see it when adjusted down to 150uA flashes of 1.22VDC. Both were without dark-adapted, using my cones and not my rods ...just turned off the room lights and tested myself within a couple of minutes, with each LED almost against my eyeball. (I measure my own dark-adaptation time as 12 to 13 minutes.) Need a bunch of these LEDs for indoors room light in complete darkness. Then you're seeing the infrared world. Your fellow humans then have alien black eyes, and much of our black clothing then looks light gray (well, light pink actually.) Also try this: get some transparent red filter, and put it over your green laser-pointer. (If any green gets through, then maybe use two layers of red.) Look into the laser, and you see red laser light. That's infrared leakage, a cone-shaped beam usually at 880nM. Now chill your green laser with an ice cube. The green goes away, and the (880nM) red light gets far brighter. Next, see if I can spin the vanes of a radiometer by using ice-chilled green laser pointer. Look everybody, I can make a radiometer start spinning by using my psychokinetic mental superpowers. But I can only turn it clockwise.

Should be good for 70 watts,, more for short time.

What’s the purpose of the video??

Thank You..Sir.

Nice

Wow, such a cool piece! Are you still selling it? I don't see it on your website

This is a nice one..!

Look cool adjustable.!

Looks Good-and adjustable..!

Probably no more than 85DB at 1 meter. We’re supposed to measure SPL at 1 meter. Not directly in front of the speaker.

Might want to tell Plogue Art Et Technologies Inc. about this.

Unfortunately the "Specs" are not available anywhere on the, "NET" for this chip and the chip requires, "Speech Rom(s)" in order to actually speak unlike the typical, "Phoneme" based units,(i.e. General Instruments's SP0256-Al-2 Speech Chip), where you can create words and/or sounds without a, "Rom",(Read Only Programmed Chip).

O wow, didn't know Electronic Goldmine had a youtube channel!! That's awesome😁Seems like having a channel for Unique and unusual store of electronic parts would be a no-brainer. That's gotta boost sales! Thanks for uploading.

Out of stock. Still thanks for the video.

How do you connect this? Is it a negative one? I assume you have to cut the battery wire one end and join the other end

Ebay sukk dik

Thanks for the two videos on this small fan. Wanted to see them running before I purchased.

Why you short circuiting battery

❤❤❤

That 1 fly that bothers u:😂😡💀

good!

Huh?

Great product. Thanks

Nice! They look like miniature "neon" tubes!

these are great

can i find something similar in aliexpress, how can i look for buttons like this?

Well, I have seen bigger domes. But nice work anyways 😺

where did you buy this fan

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.

One spot for each letter in the alphabet...

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.
