Just received this really neat LED voltmeter. It's 2-wire, so it measures it's own supply voltage, but that can be anywhere between 5v and 120 volts. And it was only £2.29 shipped. I think it's going to be a useful little thing.

His camera quality 9 years ago looks better haha. Miss old vids
why they cant make until now 2 wire up to 200vdc?
In the new versions, don't have a pot to adjust anything. I bought 2 and they are both out, one is out by 0.2v and another is out by 0.1v. Part number is DSN-DVM-368 V3.01
Will any of these measure negative voltages? I imagine not the two wire, but was curious about the 3 wire ones.
Wow, you said "just 2pounds….". From where I come from, that's very expensive. Europeans are very rich.
hey I bought one similar to these so I can put it on my bike and it says it is dc15-120v when I connected to my motorcycle battery(off the bike) it reads 21.5 when I put it on the bike and turn the ignition it says about the same when I turn the bike on it reads like 22-23 and I know for a fact my bike does not produce that much voltage so my question is because these is dc15-120v it is miss reading my motorcycle voltage? thank you in advance
Hey guys, I was just curious, does anyone know how to build a custom analog/digital meter? I need to measure the readings digitally, but I need the analog needle present, to transfer that information….. and it needs to be really small, like 1/2" x 1/2" x 1/4" if anyone knows please message me ASAP please!!!!! I REALLY need help , thank you so much
Sir how to make that voltmeter?? Can u send me a diagram?? Thank's
Could you show us how you wired that voltage meter on to the converter?
I had problem with my 2 wire LED voltmeter 5v-30v (looks like yours)I install it on car battery 74 Ah just to monitor it in my ford V6 and after siting 2 months in garage it drain compete to 0-V my brand new and full charge Banner 74Ah battery! When i remove Voltmeter and recharge battery battery is fine and after 5 weeks it drop almost noting. How is possible that this is drain so much of power? Can you test them how much of amps they using. One more thing,I check my voltage on 250cc scooter new battery and when i connect this voltmeter it drop 1V from battery. That is way to much. Battery on scooter is 9Ah. So by this in couple days batery will be dead.
hi julian what do you use the voltimeter for the two wire one my son bought some of them because he likes electronics but hes tired of it know and moved to hes mothers and left me boxes and boxes of circuits diods intergrated circuits etc and i thought id have a crack at it but i cant seem to find a use for the voltmeters pardon my ignorance and thanks
Really enjoy your good works Julian. I purchased a .5" LED 2 wire voltmeter and it was terribly inaccurate. You have not mentioned source for the smaller of the two. Did check out the supply thru Ebay of the larger, and there are vast numbers of vendors of the very same model. Funny how many use the same photo. Also trying to find a solid regualtor that will maintain 12v from both 11.1v and 14.8v LiPo battery supply for FPV camera setup on a Hexacopter. Wondered what your experience has been. Regards
120v is not high voltage lol im surprised people manage to kill them self on that
I would love to know the current draw of these. The warm heatsink tells me theyre not terribly efficient, sadly.
where can I buy this boost with the voltmeter
excuse the language but I use google translator
Great videos as always
