Electronic catapult?

Okay. I'm going to make an electromagnet to hold the spring in place while it's compressed, and then as the power turns off, the spring will release and shoot the catapult. However, I'm not an engineer-- I'm making this for tech class. How should I design the catapult so that this will work as a triggering mechanism? In what way should I set up the spring and electromagnet relative to each other? Thanks in advance.

I2C in arduino

Hi, I am trying to connect two arduino UNO together. Lets call one U1 and the other U2. U1 is master and U2 is slave. Now I want to attach a wave shield to U2 which is slave and operate it from U1. Is that possible? If it is possible, then can I use any pin to transmit and receive signal?? Cause in some forums they say that I2C is done by using digital pin 4 and 5. However, these pins are taken by wave shield. So please help me out in this.

New drop-down menu doesn't work on touch screens

The new drop-down menu, pretty though it is, does not work fully on touch screens (Android tablet and phone). The main menu works fine, but the sub-menu that pops out from shortcuts (circled in image) does not stay visible long enough to actually use - it disappears in a fraction of a second. Not a debilitating bug, but mildly annoying.

Illogical Pro Membership Pricing

Maybe I am misreading,but; the current Pro membership pricing states the prices as:  $3.95/Month billed annually; $8.95/Month billed quarterly; or $69.95/2 Years one time payment.  This would work out to $47.40/year; $107.40/year; or $34.98/year respectively. Does this make any sense?  Perhaps you ment to price the second option as $8.95/QUARTER rather than per month?  This would work out to $35.80/year which would be a whole lot more logical. Thanks for checking (I would like to upgrade but would like to know the correct prices before I do so)

Pass PVC through a plastic lid without leaking

I'm trying to pass a PVC pipe through a plastic lid into a plastic box without leaking water from the pipe or the box. The water in the pipe will be pressurized, while the water in the box will be splashed. A small leak isn't a big deal. Unfortunately, this is also a bit of a stress point, though not terribly. See the picture and the diagram below (which is actually not quite right; the pipe on the top won't be that long; it will turn 90 degrees just above the plastic lid. Any suggestions on how to keep it from leaking? Perhaps make the T under the lid flush with the lid and the same for the elbow joint above it, and then make the hole as small as possible? That wouldn't keep all water out though, but it may work for splashes. Any ideas are greatly appreciated!

Quick Question on Wireless Transmitters

Hi folks,  So I am in the process of getting an electrical device made (a people counter) and I would like to know what you think the best way of transferring the count data from the device (that will be in the doorway) back to our online dashboard is? Do I just need to integrate a wireless transmitter into the device which can then be added/paired to the network by the venue owner/manager? Or perhaps I also need to provide a wireless receiver that plugs into the wall?  Once the data has gone from the device to the venue wireless, how does it then get back to our servers and into the venue online dashboard?  Thanks!

how do I get an electronic device made?

Hi folks, I am new to this forum so please ignore and naivity / stupidty on my part and I hope this is the right place to ask this type of question. I need help and am appealing to anyone who knows anything about getting an Electronic Device Made. Basically, I require a Bi-Directional People Counter to put in the doorways of venues to count footfall in and out of a given location. It needs to be wireless (Battery operated), easily attached to a doorway/entrance (adhesively) so light weight and able to transmit the data back to our servers (probably via the venue wireless). I have an idea about what type of sensor I need (PIR) and the basic components within the device like battery, circuit board, wireless transmitter etc and I know I will require some sort of algorithm to aggregate/calculate the data and send it back to our servers. My problem is that I am not an engineer and can obviously only get so far and I don't know what to do next. From my research it would seem I need to get an Industrial Designer and a Manufacturing Engineer but both of these seem to be further down the process than what I need first. What I need is; 1. someone (an expert) who can understand the business problem I have and create the electronic device to solve it. Ie. design the circuit, tell me what type of battery I need, what type of sensors we should be using, code the algorithm to make it work and what the subsequent output of their design will be etc and for them to then produce these designs, PCB, Bill of Materials etc. 2. someone I can then take that data to and tell them to make it look pretty (presumably the Industrial Designer) by designing the case/aesthetics etc 3. to then have all the required information (functional designers / circuitry, mould/casing etc) to take to a manufacturer to put the final product together, ready for sale. Does anyone know what type of company or person I should be talking to for each phase? What are people called that do phase 1 that I outlined? Basically, I think I know what I need in terms of technology and its capabilities but I now need a professional/expert to take over to make it a reality. Any help or advice on this would be hugely appreciated as I'm getting a bit muddled and would love some clarity on the process so I can move forward in which ever direction is now appropriate? Thanks all!

Need honest opinions on Single Malt Scotches under $100 (Preferably from Scottish folks)

If you recall the dialog from the movie, "My cousin Vinnie," the guy says, "No self respecting southern would eat ready made grits."  There is something to be said about his statement.  It is emphatic and pretty much gives away the sentiment from a southern (USA) point of view. Now relate this to the Single Malts.  Can a statement be made, "No self respecting Scot would drink Glenmorangie," or whatever.  You see, my friends and I are having this perpetual debate over various Scotches, available here in the U.S. and under $100.  One of us made the comment that Macallan is over rated.  Yet, others think that Macallan sets the bar as high as it can be in that price range. No pun intended. My local liquor store carries a fairly good selection.   I notice the following as being bought on a regular basis using a total non-scientific observation: Glenfiddich Glenmorangie Glenlivet Highland Park Macallan Cragganmore Balvenie Cragganmore Springbank Lagavulin Ardbeg Laphroaig So my Scottish friends, please help me out here with your expert opinion on this topic and tell me how you truly feel about these brands.  Make BOLD statements. Thank you.

Big project, little parts..Need serious electrical tech help.

Well, long story short in my dumpster diving salvaging e-waste ... 2 Lorex CCTVs. One cord cut, the other intact. I disassembled the cut cord. Lr38603A PCB. Wires Identified GND 12v+ Audio Video  Analog, so USB is out of question. Acer Aspire 5100 laptop. The mommy is toasted (cause mobo sounds so geefy.) so disassembled and salvaged usable parts.I think I tossed the condenser into my "melt parts off circuit board" bin... so I need a condenser and PCB controller which leads me to something I found in my parts bin... CRT monitor, stripped and kept the  VGA PCB, unfortunately it does not have an S-Video and I think it's irrelevant here but I'm quite new to this hack n mod stuff... So, here's what I'm trying to do: Use the LCD from the laptop as a display for the analog camera, I also have several lens and such from damaged optics (hunting scopes, monocular etc) so with the lens I'll put them in a tube and craft a digital microscope. I know you can buy a cheapie USB one, but I want the pride of making something, to be able to understand the tech, and also re-use discarded electronics. I have a pretty good idea of what to do, but I've never worked on anything that involves a serious power source from an outlet and do not want to fry myself, and would like some guidelines/what to research. Google is not being helpful and nearly all the camera hacks I've came across are for USB based cameras. I have access to a solder station, voltometer and a slew of other parts from various electronics, mostly VCR's I'd like to keep the spending to a minimum, but not at the expense of safety. Can anyone help? Thanks :D

What is a racist these days?

Lately I have a problem accepting certain things when it comes to the label "racist". As some might know I decided to live in Australia and here we have what you might call a "multicultural population". Laws and tolerances have changed and these days swearing in public, using abusive language or say anthing that can be seen as racism brings you in big trouble. I never had any problems making friends with people from all over the globe, no matter what ethnic or religous background they have, but lately I get the feeling that this is not true for everyone. With everyone I don't mean the big bad racist living down the street or the gang of thugs that only attacks certain people - by everyone I mean those migrating to start a new life in a different country. If I walk into a shop has no pricing or product labels in english and I notice the shop keeper is unable to use english as well, would it be wrong to call this racist? If I can't use the local swimming pool at certain times as it closed to the general public so only one ethnic group can use it - isn't that racial discrimination too? Ignoring simple things like the dress code for women can get you into big trouble in many countries and if you insist on you individual rights and call those ranting against your violation being racist, well chances are you won't make it through the day. The other day I was called a racist and "complimented" out of a shop after I complained noone in there is able to speak english and that I am unable to read simple things like the price of an item. All I said to a shopkeeper (that until then pretended he did not understand anything I say): "Why the hell do I have to learn chinese in an english speaking country just to go shopping? We all speak english in this country, accept it or if you don't like it leave." I think I have enough friends from different cultural backgrounds that would happily confirm that I am not racist in any way. But I do think the term is abused and misused in recent years as we are expected to cater for all the needs anyone might have - regardless if we would see the same as guests in their home country. Racism often comes from cultural differences and misguided views on certain things as simple as what type of food you can or can't eat. So my questions up for debate : Do you think failing to integrate yourself into the customs of a country like learning and using it's official language could cause problems? Do you think the support for people migrating from other countries is driven too far in certain areas, like providing citizenchip tests in foreign languages or with an interpreter instead of insisting on learning the official language before applying? Do you feel left out if your work mates use a differnt language while you are around? Is it correct to call someone a racist if he refuses to employ people that are not from his country of birth? Are you a racist if you think people with your citizenship should respect your country and be able to speak and understand your language? Do you think the support for foreign cultures in your home land has gone too far or would more support be better? (like allowing schools for selected language backgrounds without the requirement to use or teach the official language and school topics) I know this topic might be a bit of puch for some but my intention is to find a better understanding on why cultural integration and related racism has come the extreme state we currently see in many "modern" countries that offer good social security. After all we all have to live together somehow, increasing tensions is never a good thing and I think if everyone would have a better understanding better acceptance of local customs all could be easier. I hope it is ok to start a topic like this for discussion, if you feel it is not right please use the flag function and report it.

I just want to know if GoFundMe is safe? Is there any frauds that I should be aware of? I know your project will not be seen unless you share the link but I don't mind. I wanted to use Kickstarter but it's only in the US and you need to give a reward. Indiegogo can be used for charity causes but they Take $25 off the final amount for users out of the US. GoFundMe takes 0.30 Cents per donations so it might not be too good? Please let me know what you think. :)

Can an Instructable be about something that you have for sale?

Can I develop an Instructable about something that I have designed and have for sale?  Be it a piece of electronics, a 3D Model, or a combination of the two?  Will having a link to this for sale item run afoul of policy?
