Ok folks, am trying to make a nifty dispenser for condoms (what can I say, we're newly weds and getting through them!) - should be pretty easy as they're a nice predictable size. Can anyone point to similar things or come up with ideas for a solution that might be spring-loaded, elastic banded etc to 'push' them when one's removed? Am struggling to work out how a spring might work as there's no hole in them like a staple. Elastic bands will probably wear out over time. Any smart ideas? (ideally I'd like it to work horizontally, so gravity fed's out) - Currently have a square tube of wood about 1 1/2 ft long. Many thanks in advance!

Awhile back I bought a box of basket coffee filters that the top had a tab with some kind of sticky tape on it that when you pushed it against the filters it would pull one filter out at a time. Cannot find these boxed filters anymore and mine has worn out. Anyone have an idea on how to make one of these or something like it. Thanks

I have racked my brain trying to create a laundry soap dispenser from my large tide bottle that lays on its side, it has a spout. my thinking was if i hook up a clear tube to the spout push the button and get the correct measurement for a small or large load. but the problems i keep running into is that there is a leek from zip ties or the soap drips also i cant get the soap to go into the hole where its sposed to go rather then all over everything else....

I'm trying to build an electrically controlled coin dispenser (all the coins will be the same type). I have a metal tube -just the right diameter for the coins - mounted vertically, with a piece of wood horizontally at the bottom. There is a gap between them of approx 1mm, just enough for a single coin to be visible. I've been experimenting with using a solenoid to swipe a coin from the bottom. Rather like the image here: https://www.instructables.com/answers/Petty-Coin-Bank-Design-Coin-Dispenser-What-shou/ Solenoids aren't cheap, and I was aware that the weight of the pile of coins (I'd like to be able to hold around 100) would mean it needed to be fairly powerful. In the end I bought some cheapo solenoids from ebay (around $7 each). They are rated 2A and have a hold force of 20N - this seemed a lot more powerful than I could find elsewhere for even 10 times the price. Given how cheap they are, I could even use two in parallel if I still need more power. I'm using coins with a 20mm diameter, but after the solenoids arrived I realised they only had a 10mm stroke - obviously not enough to fully push the coin away. I've tried using the solenoid to pull a lever, but this doesn't seem to work very well. Previously I'd also tried a stepper motor linked up to a disk with a coin-sized hold cut on it, rather like this: https://cdn.instructables.com/F49/GK0I/H703O9VD/F49GK0IH703O9VD.RECTANGLE1.jpg That worked pretty well but was very slow - it would take 3 or 4 seconds to dispense each coin. So, I'm looking for a bit of advice. Would I be better off splashing out on a more expensive solenoid with a 20mm+ stroke? Am I approaching it the wrong way?

Hi Everyone. I'm looking for help with finding the pieces I need to build a wine dispenser that uses inert gas (typically nitrogen). I'm fairly certain I can come up with fittings and tubing, but the real piece I'm missing is a dispenser spout and a way to connect it to the bottle, without it spewing the wine while under pressure. Once I get that, I'll have no problem building a box to mount it in. Thanks for your help.

Hi everybody! How are we all? I'm working on my latest project sending a weather balloon to around 100,000 feet and capturing the journey on camera. I've done it before as you may see on my blog www.joshingtalk.com. Anyway, my newest project involves making art at around 100,000 feet and this is where you could help! I know this could be done fairly easily but I do not have the knowledge to do it. I need a container that dispenses a small solution of liquid every 15 minutes. Now I've done a lot of research and this is the best I can come up with: http://www.amazon.co.uk/Fishmate-Automatic-Aquarium-Fish-Feeder/dp/B000YK5W18 It's gravity action, many compartments, on a rotary basis, at timed intervals BUT it will only allow for a few rotations over several hours. I'm looking for 8 rotations over 2 hours. I also checked out water timers but they seem a bit more complex. Maybe you have an alternative idea? Maybe it's 5 minutes of fiddling for you? It feels like to the right person, this should be fairly easy to overcome. I'm based in the UK and if you would like to help me with this project, I'd love it and be really appreciative! It's all good fun and you could see your device hovering at 100,000 feet.... Many thanks, Josh Update- Another vital thing I forgot to add is that this device needs to weigh under 200 grams.

I have looked all over the internet for a few days trying to find some DIY plans for building this and I haven't come across even one building plan for it. I know this is something a large number of people would love to find. I have a home business and I pack a ton of things at home for shipping. Commercial Packing Peanut (Loose Fill) Dispensers (Ceiling Mounted) are entirely too expensive for our small budget and I want to build my own. I have 7' ceilings and my packing station (table) is approx. 28.5" high. I would like the bottom of the dispenser opening (valve) to be approx. 20"-24" above the table so that I have some room to put boxes underneath it. I would like the holding area (bag) to be able to hold between 10-15 cubic feet of packing peanuts so I don't mind if it takes up a lot of ceiling space. It wouldn't have to hang very far down from the ceiling as I can reach up that high to unhook/release it to refill it when I need to. The closer I could mount the top to the ceiling the better. I could either mount the dispenser to the ceiling from each corner of the bag or centrally mounted with a chain coming off each corner and meeting in the middle. It wouldn't matter to me either way. Here's a link to what I'm looking to build. http://a763.g.akamai.net/7/763/1644/4/app.infopia.com/img/image/fp/VPID/7237005/img4/img.jpg Of course, it needs to be not as deep as I have limited vertical space to work with. Anyone with any ideas with be greatly appreciated!

Alright, so first time post here, I have been interested in converting my automatic soap dispenser from DC power to AC power using an old 5V cellphone charger. Last night I did the deed, actually really simple, I followed the general idea of this instructible, though my mod didn't include a double pole double through switch, I just took the batteries out and connected the AC charger's wires directly to the battery terminals. Here's my question though: While it works, its not quite as powerful as I though it would be, its actually a little weaker than it used to be when I had batteries with a fresh charge. It originally had 4 batteries, so I used a 5V charger. I have another charger setting around, but its a 7V, do you guys think thats too much of a jump? Should I wait till I can find a 6V charger? Am I going about this the wrong way? I really don't know anything about voltage, but the concept of converting this stationary item to AC seemed like a good idea and I'll really enjoy not having to replace the batteries all the time. Thanks for any help!

Hi all! My 11yo son is determined to make an automated medicine dispenser that releases medication at set times as his science project for school. (Inspired by 2 of his grandparents who are doing it tough with cancer). His idea is to basically automate the pill dispense so that the carer can load up each dose, and it will be released at the predetermined time, hopefully with an alarm or similar, to notify the patient... It's a intermediate school science project so doesn't need to be commercially ready, but he's struggling to work out how to automate it and attach the timer/clock function. Any ideas? I'm decidedly more mechanically minded than his dad, but that's not saying much, and whilst our son is definitely mechanically minded, up to this point he hasn't really had any circuitry etc or motors to work with, beyond lego technics etc. Is anyone able to point me in the direction of what might do the trick, without breaking the bank? Thanks so much!!

Hey Guys... need some advise and help on the initial idea and components of this project. PETTY COIN BANK: PURPOSE: - To electronically segregate coins, display the total number of coins per each case and the total monetary amount inside, with dispensing and security capability. FUNCTION: - Individual coins inserted in the coin slot will be segregated to go to the corresponding individual coin cases and each case will count and display the number of coins dropped in them and a general display for the total amount of money inserted in the device. With a security lock, the device is capable of dispensing coins. so What do you think? Some advise on how i can make this possible... I do have some ideas on the segregation and dispensing mechanisms of the project, and how to identify each of the coins from each other when inserted in the coin slot.My concern would be the Displays for the each NUMBER OF COINS that falls per case (3 displays in total), and the TOTAL MONETARY AMOUNT display that counts per inserted coin in the system. Of course when dispensing, the number of coins should be decremented and the TOTAL MONETARY AMOUNT would change as well depending on the coin and number of coins dispensed. And as you might have read from the purpose and function, this project intends to have a security lock for the dispensing mechanism. Anyone can put coins but only someone that knows the code can dispense coins. I plan on putting a keypad for that. but here is the thing... I DON'T KNOW WHAT MICRO-CONTROLLER I SHOULD USE. I plan on using ARDUINO, but what arduino should i use? and if someone can help i'd like a count of the inputs and outputs so i can decide on what to use. Thanks if someone helps on this...

Hi all, So we just got some pigs, and they eat A LOT. For our chickens and ducks, we have a feeder that is a large version of a standard cat food dispenser -- a big gravity-fed bucket that keeps a bowl/trough at the bottom full of feed. We're thinking of trying to construct a giant version of the same thing, using a big garbage can (like a Rubbermaid Brute -- they'll hold about 100lbs at a time) as the storage tank and rigging up some sort of cutout/door/bowl scenario for food dispensing at the bottom. Ideally we want to be able to move the can (when it is closer to empty) every couple of weeks as we rotate the pigs around the property, and they are pretty rambunctious so we need to make sure it won't all fall apart with their roughhousing. Has anyone done anything similar to this? Have any thoughts? Pitfalls I should look out for? Thanks for any ideas! Eileen
