pressure to flow rate conversion

Anyone know, or know where I can find out how to convert pressure to flowrate by time?

I need to hire someone to make one, possible more deivces for me

I know what I want, I have drawings, and the parts are relatively inexpensive and easy to get. It is a small LED based item similar to a children's toy. (parts are even used from inexpensive children's toys). I simply don't have the knowledge or time to put it together. If all goes well I have another device I need made as well. With the right person I will of course pay (I hope paypal is ok)before you start. I would strongly prefer someone with experience and someone that has posted projects on here before with LED experience. Please contact me at:

RF Development Kit-Advanced, but could be a lot of fun

Micrel SemiconductorEbay{{{ I have noticed that some people are concerned that due to surface mount technology you can't make electronic stuff anymore. It is not true. A search will quickly find forums discussing how homebuilt electronics experimenters are getting around this. I have a nifty RF development kit for sale on ebay. See ebay link below. These development kits are used by new product developers to quickly get their RF prototypes up and running to develop software, hardware and firmware without the steep learning curve associated with starting development with discrete components. These boards allow you to build custom devices that can comunicate with each other up to a mile apart. Although this is not quite ham worthy distance someone might be able to have some fun with the kit. I have just one, but more (and the actual rf chip) could be acquired through Micrel Semiconductors. Anyway, I have this listed as an industrial item, so I am not sure the right people will see the ad. For those interested in playing with current technology RF.}}}

First Tuesday Following the First Monday of November is Fast Approaching

First, I'm not pushing any ideas on you - that's your job. For those of us in the United States, next Tuesday is election day. Surprisingly, some people don't even know this. If you're realizing that "Hey, I'm not sure what's going to be on said ballot," now (or even this weekend) is a good time to sit down for a little bit and research/find the people you feel speak and represent you.The resource I happen to use is . They do not accept any funding for corporations, PACs, or any organization that supports/opposes an issue/candidate. The service is free (all you need to know is your 9 digit zip code). The site lists the current candidates, the challengers and a whole lot of information about them (experience, voting records, candidate websites, etc.). You also ought to look at any amendments that will be on your ballot -- the wording can be quite tricky (In the last vote, FL had one amendment against the amendment not to build a monorail train* -1) so you probably want to make sure you are in fact voting for what you want ;)So, please take the time to vote next Tuesday. Staying home is NOT speaking out against "the man" or showing your disdain for the system, the person, the amendment on the ballot. I am personally driving four hours to my voting place - it's really that important...Again, I have the utmost respect for those with different views than my own and the same for those that share mine. I'm not pushing any idea on you (other than to actually vote) - I just want to put it out there that its that time of the every other year again :P

Water Tunnel Testing (photos)

I'm starting a new topic so I can edit it later with more content.I went with some friends to a different lab section that was also playing with the tunnel (my official turn is on Friday).Things put in:1. PVC tube -- to show detachment of a cylinder2. Golf Ball -- to show how dimples create turbulence and keep flow attached longer3. Tennis Ball -- to show how fuzz acts almost like golf ball dimples4. Porsche 9115. Atlantis Space Shuttle6. Porsche 911-turbo (or possibly a 935 or 993 -- can't remember)7. Chain Mail Cube -- wtf? why did someone make that?8. Surf Board Fin9. Optimus Prime10. Unknown Porsche (I just can't remember what it was)11. Batting Cage BallThe pump was set to 3.55 inches per second. So for a 1/64 scale model (for the cars) - that's just under 13mph equivalence (in water).My camera had a low battery -- so the shutter was slower than normal. I'll get fresh batteries and a tripod on Friday I'll have some better pictures (hopefully).As for what I'm bringing in... Still don't know -- but I think I am going to do a comparison of apples and oranges :PVideos of the 911, 911turbo, unknown porsche and of the overall tunnel in operation ;)Update November 3rdItems Tested:1. Plastic Cone (with hole in top)2. Apple3. Eyeglass Case4. Obligatory Altoids Tin5. Plastic Water Bottle6. Highlighter Cap7. Reverse Gear from a manual gearbox (Nissan)8. Pen Cap thing9. Rubber Duck10. Nerf Dart (velcro top)11. Batman Shield (this was really cool)12. Welded Plate13. Golf Ball14. Guitar Bar15. Wing FoilAgain, it was set to 3.55 inches per second. I couldn't find an orange on campus (weird considering I'm in central Florida :P). So I'd say an orange is kinda like a golf ball :PThe Bat Shield video is very cool - if you watch just one of them, make it the bat shield ;)

Question about electric motor ratings

So, lucky me, I curb surfed a table saw last friday, I was going to part it, but my wonderful wife suggested that I could benefit from an extra saw. So deciding to fix it up, I looked over the motor rating, and was left with a question. The motor is rated at 1&1/2 Hp 110v 18 amps. So my question, When is it 18 amps? Start up? Running? Stall? I ask because my breakers are 20 amp, kinda close there for comfort, and no re wiring for 220 right now is not an option.

I'm getting tired of these EasyEDA promotions masquerading as Instructables projects

Seems there are at least 5 Instructables projects recently that are obvious promotions rather than true maker projects.  I'm disturbed by this.  I have no problem with someone recommending a company or product that played a role in a successful Instructable.  I do this all the time.  But if compensation was provided (free PCBs from JLCPCB because they are offering a fee order to anyone that promotes their service, for example) that needs to be clearly stated up front.  That is the ethical thing to do. But, the Instructable needs to be meaningful!  Not, "Here's how to build a 555 timer circuit using JLPCB".  That's completely bogus.  At least TRY to make something useful like a guitar stomp box or a multi-channel audio mixer or an Arduino relay I/O project.  Not some crappy 555 timer circuit, or basic transistor circuit, or a project that has no other redeeming feature than it looks cool when assembled on a JLCPCB circuit board.  Please.  Raise the bar.  If you are going to promote a vendor, don't be lazy, make it an interesting project that is worth my time to read.

I Need a little Help with Shift Registers

Hello, I'm both new to Instructables, and electronics in general. I'm trying to make a Divergence Meter, but I'm using LED's instead of nixie tubes. (It's safer for having my little cousins around.) I'm hoping to control each tube with one shift register per tube. Each tube will have 11 imputs and 1 output. I was curious if you guys had any tips on how to do that with the standard 16 pin registers, or if you could direct me to one that could do it. Thanks.

Anyone know how to make an alarm that knows if my dog is being stolen?

I live in an area where people steal dogs out of our yards. I want to build an alarm that does two things: it allows the dog to roam in an area like my yard without going off and if he's taken, it goes off. The second part is that it sends a signal so I could track it on an app and help the cops get my dog back. There's got to be a simple way to make one with a Rasberry Pi or Arduino. I've never used either and want to learn, probably with the Pi. The dog would have to wear it on his collar naturally. Any help is greatly appreciated. I'm brand new to Instructables so you've probably seen something like this before. Please help. I'd love to make them for Christmas for several family and friends through our church. Thanks, Mike
