Hello Mjlorton, We just came across your review. We appreciate all your thoughts and suggestions. We will also be improving the checkout experience to better reflect the expected shipping. Also do consider Braiins Pool for Lightning Payouts.
Thank you for your very thorough walk through! It was exactly what i was hoping to understand for different application on a product we manufacture for transferring diesel while monitoring high on/off limits. As a previous water well contractor, i commend you for this clever use for monitoring a leak or a run dry scenario. Whenever your pump decides to go out, the tech will likely need to replace the wire going down the well. Based off your HP i'm guessing it's roughly 150'-250' deep. If you go to a 3 phase motor, you can run it on a drive (i always used the yaskawa IqPump micro) which is a bit more expensive but makes up for the cost in the price of being able to reduce wire awg. Those drives have pipe break, run dry, and a slew of other options that specifically target amperage dips and an array of inputs and outputs. Another alternative if you have a two wire pump or just dont want the 3 phase option is to use a symcom or franklin electric "pump saver" which works off the same amp dip and is a bit more economical. Anyways, thanks again for your demonstration, i have some re-wiring to do ;)
My Fluke 332 is the lesser B version i bought used 30 years ago. It went under salt water in Katrina and is in my Junk maybe fix maybe wait stuff. Lol. Even odder i have an ancient HP voltage calibrator too. A HP 738BR that is all tube based.. the voltage reference inside is a tube not a zener diode.
This is by far the most technical solar deep dive i've ever seen and i've watched quite a few youtubers cover the same thing. Thanks for sharing you setup as it's been really insightful.
Truly exceptional explanation here. I have come across one of your videos before, but had quite forgotten until I stumbled across this - Yet again Martin, I’m astounded at your ability to convey really quite complex topics with brilliant analogies and clear, visual explanations. I wish I had teachers and lecturers with your skills for passing on knowledge at college and University 🙌 🙌 🙌. Glad you skipped revisiting complex numbers - Have vague recollections of the anxiety they first induced when badly taught to me in my first year at Uni. The other thing that really tickled me was that I’d been reading some standard text online (trying to refresh my memory/understanding) about op-amps, covering differential amplifiers and feedback loops, when I got distracted, thinking why the voltage output ‘very nearly’ follows the input (with feedback) without oscillating out of control, unless the op-amp gain was unity (and not 200k or so as is common). Spent a few minutes scribbling down some ideas before deciding to just leave it alone, as the text didn’t cover it and move on - Then later the text then came up with an explained jump from the formula Vout = Gain (V+ less V-) and (magically) “solving for the output voltage we get the following:” - but without any mention of complex numbers or how they ‘solved’ the math 🤣🤣🤣 - Vout = Vin / 1 + (1/G). Anyway, somewhat serendipitous and bizarre that hours later I found your video which totally nailed the subject and filled in all the gaps others had conveniently left out. The World needs more teachers like you. Well done 👍
If what ive read about this is true its only 30 cents a day profit, thats trash, not even worth screwing around with, besides heating up your house has got to be horrible in summer. And then you got electric costs, i dont see any upside to this besides a lottery chance. Six month to withdrawl because a minimum to with draw lol. This is a toy i wont be buying
Top quality information. If a company fails to response or provide decent feedback, then I would prefer not to deal with them. This is an issue with many companies and does not provide consumer confidence in their products. Please keep the videos coming.
I donot have the time or money to develop a new moisture meter. But you seem to have equipments. Can you build such a device, say that has a cubic enclosure, that has a laser to heat up a surface, it should vacuum out air in the enclosure, the laser will heat up a defined region, and then a probe inside the enclosure will measure the humidity generated.
Everyone is marketing this piece of shit called Avalon Nano 3 This is not a miner , it is a toy for kids to play with and learn mining If you use it for mining you will loose money, the block may cost you up to $1000 of electricity It is a bullshit advertising for a piece of garbage !!!!!!!!!!!!!!
Thanks for the video, glad you returned to yt :) I made myself a simple well water level meter with an ESP8266 and a cheap ultrasonic sensor, it's battery operated (battery lasts about 4-5 months) and it sends readings every 15 minutes. It is pretty accurate, within +/- 2cm (in my case 1cm water level equals 5 liter) and it works well for several years now.
Hi Martin, a bit off topic, I see your lovely -002 optioned 3458A in the background there, can you believe it is 8 years since you replaced the Snaphat batteries! Did you ever export the calibration data as a backup via GPIB……?
I know another youtuber had a faulty DMM from uni-t too, they sent a replacement meter, unfortunately I dont remember who it was, maybe Kerry Wong or Tony Albus
I've been trying to get in contact with Uni-t myself to get them to send me stuff to review, so far they haven't relied to my emails... seems they are sending things to a lot of electronics youtubers, but somehow missed my channel.
LOL... I have a Fluke 107 in my mobile tool box and it works great, also have an Amazon Commercial 90DM600 (very rugged and IP67 rated/ usually at home), an Extech EX350 (355 without temp - great full featured), a Southwire 15190T, a Fluke 87 V, an Aneng 8009 (used as a loaner when some techs are over at our store) and a few pocket “throw abouts” Sanwa PM3, Hioki 3244-60, Zotek 921 and Aneng AN101. All of them great in their own way !!!
LOL... the Amprobe is a sister company of Fluke (both owned by Danaher)... Sanwa and Hioki are totally separate but definitely Japanese as their plain / austere style but high quality reflect !!!!
Hi thanks so much I am saying to you Excellent I will be looking at all your Videos I would be willing to pay to Subscribe All the best my friend I will be staying in touch 👀🥇🥇🥇🥇👍🏻🍺
