That was brilliant. Can this be done at a lower voltage though? Trying to think up a way of doing this on a smaller scale - likely with a fan passing air thru
It can be done using a static electricity generator that produces a much lower current which is much less likely to kill someone than using a microwave oven transformer but that is still high voltage. The high voltage is necessary to establish a strong enough electric field to attract particals as well as corona/ionization to charge the particles. The only low voltage means would involve mechanical filtration and heat based filtration techniques.
Oh my gosh...I just found this video because I have this problem and I haven't laughed this hard in a long time!! Thank you for the hack.. and laugh!!😂
Can you share the files that you used for the PCBs? I have some students who would love to build this but I can't also walk them through the PCB design process.
GREAT video: PLEASE HELP ! ! wouldn't it operate the same if you just had a U shaped trap at the bottom of the main water exit? That would eliminate the need for a "T" ? ? Someone please help me understand why a simple U trap wouldn't do the same thing.... Thank you all in advance for the hundreds of replies I'm sure I will get to this question.😀
Great question. So a simple U shape will not work for the following reason: the water that is in the chamber would not be displaced past the opening tip of the "u". Imagine a full chamber. Water level drops as air displaces chamber but the water level drops past the entry of the "U", the only water that is displaces is the small amount within the U bend.
Yes unfortunately with esp there is always some ozone produced. The activated carbon would absorb some. There could be one pod made from a specific absorbent for ozone which are similarly used in cpap machine cleaners. Other option which I was exploring was to use an electro spray technique which I couldn't get to work as effectively but that could have just been my inability to produce a good setup with optimal parameters.
its the corona that will produce the ozone. From there it is the voltage level how the terminals are designed to produce the amount of corona and the amount of oxygen present to be converted to ozone. I believe the polarity of the voltage has an affect with positive voltage producing less than negative.
@@LockeLaboratory I'm intrigued by this type of air filter and intend to build one to remove solder fumes, but the ozone worries me more than the fumes. When you have worked with this, have you ever felt a certain smell around the apparatus? (It's a very distinct smell)
@@LockeLaboratory Also, can the corona discharge be tuned in order to produce less ozone without making the filter less effective? And kudos for being active 8 years after you published the video 👌
@@minime9400 thanks! Yes ozone is a real concern which may negate the practicality of this device for home use. There are some moves to minimize effect of ozone but it will never be zero since corona is also required to ionize incoming gas. In general what increases ESP's filtering power can increase ozone generation rate unless you do something expensive or exotic such as using an oxygenless environment or perhaps converting to electrospray to turn the ESP to a wetscrubber. There are optimal parameters for ESPs and I'm sure there are research papers written on it. In general sharp protrusions increase corona production. Typical design is a wire within a cylindrical tube or wire sandwiched between plates. On the wires are the series of barb protrusions to concentrate the electric field where corona is produced. Yes stopped making new videos since not much time anymore. Hope to find the time again to make more videos while juggling a busy life.
....WOW!!!!!! I WANT TO KNOW IF A "THEREMIN" WILL RESPOND TO ANY "METALLIC" OBJECTS, WITHIN PROXIMITY TO IT'S ANTENNA?!!!... COULD THIS BE USED TO "SWEEP" OVER TALL GRASS, TO FIND METAL OBJECTS?!!...
I dont think a theramin would do a great job of this? I think the antenna responds to grounded objects such as a person. A metal detector would be a better tool for finding metal.
you might be able to improve the working of this device by also adding in some soap. doing this will reduce the water surface tension, as well as making it more easy for dry and/or hydrophobic particles to get into the water and stay into it.
I like that they are not permanent. I have even triedt to use adhesive caulk but it fails because of the changes in the temperature in my garage and the coating on the board. I like your real world testing method. 👍
Hi Jimmy, how do you ground the theremin? I didn't understand how do link the test lead to the earth port of the main outlet. what do I need to buy to that? Thanks.
There is a grounding pad on the bottom of the theremin. I just used a clip on test lead to clip onto this ground pad and with the banana jack end of the test lead into ground port of an outlet.
No, this is not a good solution. The clip is ugly, flimsy, and occupies the space where the tool should hang. It looks dreadful and messy, not neat. A creative idea, but not a solution. I am sick of the price gouging on flimsy junk that is sold as a retainer clip. You have two solutions: Use hot glue gun to keep retainers glued in place, or build a plywood tool hanging board with custom storage for all tools. No more pegboard! The advantage is, you can build in sections so it is modular and easy to move along with you, or as a folding cabinet - no dust, layers of walls inside for compact storage.
Hi Jimmy, how difficult is it to solder the parts following the BOM? Found a seller on Aliexpress that sells the PCB with components - just need to solder the parts onto the board and install with a arduino. wonder will this be doable for someone with no soldering experience. thx
I would always encourage trying and taking a dive to learn new skills. It can be fun, kind of like building a model. Its kind of like learning how to ski, first time is often lots of failure but by the end of first session you may have already gotten the hang of it. If you have a steady hand and the right equipment, it isn't too bad. The trickiest parts for this kit may be the header connectors that adapt to the arduino as well as the IC chips. I'd recommend also getting a practice soldering kit to try first so your first try isn't spent on the theramin kit you found. You will need tweezers, flux, solder, solder braid, and a temperature controlled soldering iron. Best of luck.
Thank you so much. I'm about to install my peg boards and hooks into my new art studio and thought about the hooks falling out. Found this video and it's gonna save me from frustration not to mention using all these paper clips 😊 Also thanks for showing a realistic rough handling 🤣🤣
That's amazing! This is my first time using a pegboard and I was excited about organizing my tools and then the pegs kept falling out! I didn't want to buy new pegs and I thought, "There's gotta be a hack that someone came up with," and found your video. The way you aggressively test whether it's secure no matter how roughly you pull the tools out made me excited about organizing my tools again. Plus, I have hundreds of paperclips going unused. Two birds with one stone! Thanks for sharing.
1/4" silicone/rubber tubing is better. push in tubing (1/4" inch play per side), don't cut tubing until desired length in (need tube for fanagling it in:). It works like majico! Have a nice day. Oh, no need to order anything! it's sold in all ACE/H.D/fish stores etc...If crazy or insane...Hot glue it in place, either way, it works! WD40 is fun if probs occur. Just for laughs...You got to lube it, lube it. Really say's me?...Not :) Oh...it's only $5-7 for yards of it.
