Great tutorial! Hoping you can teach us to make our old AC powered conventional study lamps into DC powered rechargeable lamps. More power to this channel!
Now you can upgrade this by inserting a small perfume ball valve near the discharge port of the pump so that the fluid doesn’t go back to the tank everytime you it goes off. This will act as a gravity one way valve or a check valve. Fluid output will be smooth as sanitizer. You can find the metal 2-3mm metal balls in so many place. Bike hubs, perfume bottles etc. Nice project.
@@TechBuilder Hey!, I love your DIY project very good , nice and helpful. Could pls. a vid using this with a solar panel or a solar powered DIY contact less alcohol dispenser? hoping foe your response - willing to learn and an avid fan😊
@@akshitaddanki3607 I made it today and it is working perfectly fine. You might have fried the transistor while soldering. Try with another transistor (attach a small heatsink to it while soldering).
Hi! You're probably not gonna see this comment. But I just wanted to say that the style of your videos reminds me of the late Grant Thompson, I surely do miss his vids and it's kinda nice that I was reminded of him again. Also salutations from a fellow countrymen! Stay safe y'all P.s. love your vids!
Hey I love the channel being active again. These projects are great and just in time for lockdown. I am going to be the pronunciation police here though. Isopropyl its pronounced like eye-so-pro-pull. At least in American english. If I recall you are in the philippines so I fully get not knowing this and it does not bug me but I know if I was saying a word wrong I would want someone to tell me how its pronounced.
Neat idea I guess... The only problem is that people are used to holding their hand under the dispenser and waiting for it to dispense it's preset amount. It isn't intuitive to have to remove your hand to stop it from dispensing, as this may lead to spilling. Since the IR sensor's output will remain high for as long as you hold your hand under it. I suspect users may hold their hand under it for quite a while until they realize it doesn't stop automatically. This would waste quite a lot of alcohol.
One note. Beware on the wire colour in the USB cable. Often times they don't follow standard colouring, so it's worth checking the polarity with a multimeter if you have one.
Agree! Although it barely happens, I've had the same enounter before. It damaged my project. I did however check it on the actual video, the clip was removed to shorten the video length.
I tried this . But dont know what I messed As the pump is running continuously on turning on power Also the proximity sensor I got had 4 terminal namely AO DO GND VCC Plz help
I'm student of biomedical engineering.. now I'm still searching for my project and thankfully i see your video. I think i want to try your idea. Thank you very much✨✨
Good idea..... however I think after a bit of time the alcohol will corrode that motor (oxidizing the metal shaft) and possibly the glue/adhesive that holds it's housing together. There is also the chance of ignition of the alcohol from the small arcs those DC motors make when powered. Perhaps run this for months and see what the outcome is.
Thanks! I've been running this project for almost 2 years now, the older one that is. This one's just a documented remake. I had exactly the same concerns, so far so good. As for the arcs, as long as there are no oxygen or air to feed the fuel from sparks, I doubt it would ignite.
I have a suggestion to improve the design. Connecting a capacitor and resistor to the transistor can help make a cheap timing circuit. This is good if you're only trying to dispense a small amount of liquid like rubbing alcohol on your hand. It also helps alleviate some problems when glitches on the sensor module might occur or when you point an autofocused camera to the sensor that might cause it to unintentionally go off and dispense large amounts of liquid.
Can you teach us on what type of capacitor is needed? And where to put the capacitor? Because my main problem is the current is slow when you try to activate the pump(we tried it on the breadboard) so the main problem that I have is the slow flow of the current to the pump
For those concerned about the wires and pump being immersed in alcohol, you can probably put the pump outside of the bottle then just insert another tube into the bottle for the source.
I made this but whenever I try to put the battery, it automatically starts pumping; after that it functions normally. Can you tell me what's the problem?
Hey there. Great DIY project. I have an issue with mine. The pump is failing to pump the sanitizer all the way up the tube. The sanitizer gets stuck somewhere along the tube. Any advice on what I could do to solve this issue?
This is great - I made a bedside vodka dispenser using this design: Industrial pump, 25 litre vodka container and tube straight into my mouth, activated by blinking my eyelids. I tried activating it by waving my hand but after the first litre or two I couldn't even lift my arm. With the eyelind blink activation I can now get vodka as soon as I wake up. I used the leftover tubing for a catheter which neatly solves the problem of no longer being able to walk after the first 30 minutes
I love this DIY and I am looking to use it for a different application. Would it be possible to use this with a 3000 l/h water pump? will I need to use a traditional power outlet cable, will that melt, or will the usb be strong enough?
Excellent.... May Allah reward you I would like a link to buy the parts because one of the links inside the description box is not working رائع ... ..... جزاكم الله خيرا اريد روابط لشراء القطع لأن احد الروابط داخل صندوق الوصف لا يعمل
Fiq Azhar no, you need itu to be a gate for electricity. Sensor give electricity for base transistor to flow electricity form emitter to collector to pump. It’s be a swticher
what’s wrong with hand sanitizers? Though the occasional use of a hand sanitizer isn’t going to hurt you, regular use over time can cause a lot of problems: 1. DRY SKIN We told you about the dangers of alcohols in skin care in a previous post. The alcohols used in hand sanitizers include isopropyl, ethanol, and n-propanol. These are the drying alcohols we told you about. They irritate the skin, strip away it’s natural oils and acid mantle, dehydrate cells, and increase risk of contact dermatitis. 2. ACCELERATED AGING All those drying effects can lead to increased appearance of fine lines and wrinkles, as well as calluses, cracks, and flakiness. Over time, alcohols can disrupt the natural barrier function, reducing skin’s ability to protect itself, and leading to increased dehydration. 3. DAMAGED SKIN Scientific studies have shown that alcohols can actually damage skin cells. 4. ANTIBIOTIC RESISTANCE Many hand sanitizers these days are made with triclosan (more about triclosan in this post). This antibacterial has been found in animal studies to disrupt hormone function. It’s also connected to the rise of so-called “superbugs”-bacteria and viruses that can resist antibiotics. The CDC announced in 2013 that the rise of superbugs (as a result of overuse of antibiotics) was a serious threat to human health, and had caused at least 23,000 deaths that year. 5. UNKNOWN CHEMICALS Many hand sanitizers are made with chemical fragrances. Since manufacturers are not required to list fragrance ingredients on the label, you don’t know what you’re exposing yourself to. Many fragrances are irritating and have been linked to allergies and hormone disruption. 6. WEAKENED IMMUNE SYSTEM We think we’re reducing our risk of getting sick when we use hand sanitizers, but they can actually weaken the immune system. Studies have shown that ultra-clean environments-particularly early in life-can contribute to reduced immune defenses later on. 7. THEY JUST DON’T WORK AS WELL The FDA states that currently, there is no evidence that antibacterial soaps (and sanitizers) are any more effective than regular soap and warm water in helping to prevent the spread of germs. A 2000 study found that sanitizers do not significantly reduce the amount of bacteria on the hands, and may actually even increase it. Researchers added that the products strip the skin of its natural oils-and since those oils usually prevent bacteria from coming to the surface, the sanitizer can actually reduce the skin’s own defenses.
Nice much cheaper, I've also seen the first version cool now to build this No problem for me I can Diy this easy cause I know electronics but for a simple person with less or No knowledge they can't do this but they can try though; Or maybe I'll just build one or two and donate it to a Hospital thanks god bless
In this configuration no, because the proximity sensor shuts off immediately when nothing is detected. It will run as long as something is in front of it. This could be limited to prevent abuse with a second transistor and a rc circuit which cuts the connection when the capacitor is fully loaded and resets after a short decharging period.
I agree with @oneBACON . You can use a two transistor circuity or perhaps use a 555 timer to add intervals, although the 555 wouldn't give you the cut you need.
@@onebacon_ I understand the principle behind what you said, but could you elaborate on what type of transistor, resistor and capacitor I would get and how that would be wired together?
Nice project. But you should not use submersible pump. It is not safe to pump alcohol by these kind of pumps. You should use dosing pumps specially made for alcohol & other volatile liquids. Rest for your electronic parts you deserve 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Slaps an Arduino on an esp8266 then a Raspberry Pi 1,2 3 and 4 then a lattepanda, then a pager then a Tiger hand held game then a bucket of sand then a singularity......then boom time machine made! 🎰📠
Once again, a very cheap build. Dami ko nakita gumagawa puro arduino ang board. But this one is way cheaper and can even be compact if it has its own housing with a rechargeable battery pack..
lazada at shoppe kaso indoors lng yan guys.. pag may sinag ng araw kahit hindi directly from the sun bsta maliwanag.. aandar ang motor at tuloy2 ang labas ng alcohol..
