confetti blower clogging

Hello everyone. I have a question which I think will be a simple one for you guys. I bought these mini confetti blowers for our church. They suck confetti, which are mainly small shiny rectangular pieces or some rose shaped paper-like material pieces, and blow them to the air. So ours came with a hose setup to suck the confetti: http://i.imgur.com/L3dzXMM.jpg I decided to modify it to suck confetti from inside a box like these ones do: http://i.imgur.com/EkE930u.jpg Here's a sketch of how it looks now with the box I made. http://i.imgur.com/Q5rPvfp.png What's happening though, the confetti pieces after few seconds form a clog where the box connects with the tube. http://i.imgur.com/pd7ZYFL.png If I push that clog with my hand, the confetti is sucked in and flows through the tubes and is blown just fine. I modified my box from the inside like so, but it didn't change anything. http://i.imgur.com/60vn7yW.png -> http://i.imgur.com/F5hzBwr.png Someone unlike me who actually understands why that is happening, can you explain why clog happens and how would you suggest me to modify my box shape to fix this? Not that the hose setup is bad, it just looks like a modified vacuum cleaner like that and not very pretty to have in ceremonies and we still need a box to put the confetti pieces and the hose in to suck the confetti so I thought I could just have the box on the machine itself and make it easier to handle.

Self loading confetti cannon Answered

I'm dressing up a golf cart for parade duty. I thought the "exhuast stacks" should be used for confetti cannons. However I don't want to stop jump out and dump more confetti down the pipe in the middle of the show. Any Ideas?

Pump pressured confetti cannon

I am hoping to build a football pump (or similar) pressured confetti gun, it would fire by pumping air thus making pressure for when you fire it will fire into the air, maybe 1-2 metres perhaps. Any help. Also it needs to be built by october 25

How to set thickness of the wall with thread? - confetti launcher

We are working with my kids on CAD project - precisely on a simple pressure valve for DIY confetti launcher. Yesterday we decided to design a thread, which assembles nipple of the valve to the wall . We prefer 1.6 mm wall (0.064 inch) because that saves volume and is enough for 1450psi air in case of stainless stell grade 310 (my son found a piece of SS at home, so we decided to use it). However, I'm afraid that in case of turning a thread there would be a need of redesigning wall thickness.  Question: How much thicker should be a wall for 1450psi (working pressure, pumped air or co2) if we add a thread reinforced with green Loctite (hard glue for threads)? What is optimal metric thread for that pressure?  I would be very grateful for standard, formula or table.

Ball counter or weight sensor with relay to sound alarm or trigger 9v confetti cannon

Anyone interested in a bit of work...I could also run it as a competition. Apologies in advance if what I am doing in not allowed on instructables, but I couldn't find a place to offer this work. Peoplehour does not specialise in tech gadgets! I am a one man band training business in the UK. I am trying to find someone to make this gadget to work with my Gravity Ball Game. Gravity Ball is a two hour team building activity. Gravity Ball requires teams to design and build a construction capable of transporting a ball from one zone to another; the ball must roll freely along the construction using gravity only. There will be a shared zone that will require team collaboration, co­operation and coordination. Everyone needs to contribute to the overall team objective whilst ensuring their own structure functions to a specific brief and works correctly. All teams will release their designated ball (tennis ball, golf ball, cricket ball, squash ball. Etc.) at the same time. Each team ball will roll freely along the team structure, into the shared area and the fall into a collection container. When all the balls are in the container (and a specific weight achieved) then the Weight sensitive relay switch will detonate a electronic confetti cannon. Alternatively, an infra red or sensor can count the number of balls that pass at a particular point and when the designated number is reached, the confetti cannon will detonate The detonation will give a wow factor to the team activity. Considerations: I need a gadget, Arduino, raspberry pi or beaglebone that can measure or count the number of ball and then detonate a confetti cannon or sound an alarm • Programmable weight or ball counter setting • Maximum weight 300g-400g or Maximum number of passing balls is 10 • Work with standard electronic confetti cannon from Confetti Masters, alarm or Siren (http://www.confettimaster.com/streamer.electric.confetti.cannons.html) or Showtec electric cannons (http://www.sblite.co.uk/598-80cm-multicolour-electric-confetti-cannon.html) Message me if you are interested! Kind regards Canute

At room temperature, how much pressure does a 12g CO2 cartage output? Answered

...and can it be controlled by a 10 bar rated 12v solenoid valve? I'm thinking about making a remote controlled Co2 confetti cannon and I'm planning on using a 12v 3/8" solenoid rated at 0-10 bar which will be operated by a relay controlled by a networked arduino. I realise that they run at different pressures depending on their temperature, but this will be used indoors. Thanks!

Prop Help!!

Hi, I am working as a crew member for the musical Little Shop of Horrors. We need to trigger a confetti blast, a strobe and a sound clip to play with an 8th of second of each other. I was thinking of using a paintball gun (without paint balls) hooked up to a solenoid (or motor with a cam) linked to a computer controlled relay. The plan would be is to use a some wading to launch the confetti out of the gun and have the strobe only blink once right as the sound was triggered. Also we are not allowed to use real pyrotechnics because the madison fire department sucks (safety first, i know). So I guess we could use ether a paintball gun, or an air compressor that is located off stage with a really long line. Also it needs to all fit on a cart the size of a bed side table. So, how should we control them? Computer controlled relay or something else? Also if possible we would like to make the whole thing go off remotely. Either using RF or inferred. Worst case scenario is a small wire that singers/dance wont trip over and die. All suggestions and comments are welcome!! Please comment with any ideas no matter how simple of difficult!! Thanks in advance.!!!!!!!!!!!!!!!! Joe Rowley

Machining inside cylinder vs machining thread?

We are working with my kids on CAD project - precisely on a simple pressure valve for DIY confetti launcher. Yesterday question had occured: what is cheaper and easier for hand turner (alternatively cnc machine): to machine a nipple and  then turn a thread on a cylinder or to machine nipple inside cylinder? How much bigger is cost of one of these options?  I prefer turning inside cylinder (no potential problem with sealing), anyway I'm asking this question to more experienced people.   PS: Size is showed in mm. We consider using metric thread.

A Moral Quandry About Posting - Advice Sought

Hi all, I'm having a bit of a dilemma regarding an Instructable for April Fool's Day. I was considering posting an idea I had for pulling the classic schoolboy Flaming-Bag-Of-Poo-On-The-Doorstep prank, only at great distances. It's a thought I had several years ago when a colleague was irritating me, and I thought "I'd really like to leave a flaming bag of poo on his porch. Too bad he lives 2000 miles away." Obviously, this is not something that I would actually do. It's intended as an amusing article about the theory of the thing, not something to make in real life and use. Mailing combustible materials is illegal and dangerous, potentially lethal, prosecutable under terror laws, and just generally a bad idea all 'round. Also, the mechanism of the thing could be easily repurposed to initiate a much more dangerous payload than a paper bag full of poo. Honestly, the device is pretty much a mail bomb with a joke payload. My major concerns are 1) there are people out there who would be dumb enough to build it and prank someone, thinking they could do it safely; 2) there are people out there who are malicious enough to build it and use it for intentionally destructive purposes; 3) The mere presence of the article on the site could potentially attract government scrutiny, and if someone actually were to get injured by such a device built from plans found on this site.... On the other hand, Kiteman's 0th. I have considered redesigning it so that the payload involves something innocuous, like a spring-loaded confetti launcher or a recorded message, but the humor of the thing really depends upon the absurdity of mailing someone a flaming bag of poo. Mailing someone a sound bite that says "YOU SUCK" just doesn't have the same impact. Plus, it costs more to make. Poo is free. Anyway, what do my esteemed colleagues think? Am I being overly cautious, or am I right in just shelving the whole thing?
