Build the simplest $3 Automated Alcohol Dispenser without using Arduino. Keep your hands clean by filling it with liquid soap, hand sanitizer or with rubbing alcohol. By reducing physical contact, an automated dispenser keeps virus from spreading around in communal areas.
INSTRUCTABLE TUTORIAL:
www.instructables.com/id/DIY-...
THE DESIGN:
I've seen several Arduino automated liquid dispensers circulating the web. I find using Arduinos a bit overkill for this specific project. Arduinos are far too expensive. I figured using a simple transistor or MOSFET would do the job, which would also drastically reduce the costs. Obviously, the absence of a micro controller removes control of over spilling, but then, I did find out that using a smaller nozzle would physically limit the flow of liquid. There are several two transistor RC circuits that would solve the over spilling problem but the single transistor design works well, given that you choose the proper nozzle size.

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.

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

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.

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.

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.
@TechBuilder
@TechBuilder 4 жыл бұрын
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.

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.

Is there any way to control how long the pump is activated for once the sensor detects a hand?
@onebacon_
@onebacon_ 4 жыл бұрын
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.
