This concept is very effective when I first encountered this article it kinda seemed like it could be total BS!! But it absolutely works!!!! There is one thing I think he forgot to mention and that is this works best with the old school mini dishes that are perfectly round not the new HD models that are oval shaped. I also took this concept a step further instead of using a usb net adapter I used a wireless range extender and mounted it to the collector. By doing so you create a wireless AP that you can connect multiple devices to simultaneously. But in order to do this you have to manually configure the range extender since I'm assuming you will not have direct access to the intended network which requires a little bit of know how but nothing too technical. You will need the SSID, subnet mask, gateway, and the channel. After that it is just a matter of taking the time to fine tune your alignment for the best transfer rate. if you have knowledge of the exact placement of the router you intend to bridge that will allow you to get about 90% of your potential signal.
I think anchoring the base would be a good thing. But i've never swung on one of these myself, lol. So maybe the stock base is good enough.
hello, nice to meet you, i'm tom from Zhengdian Electronic company(China) which specialised in manufacturing led writing board, led light box and kids led drawing toy.maybe we can have a cooperation. any needs, pls view http://www.ledwritingboard.cn or email to: email@example.com Thanks~
FYI background most 3 phase motors are dual voltage 220/440 or 110/220...Click the pictures.
I have a way to make this a little more convenient. Open the phone casing, and remove the antenna coil. Cut the two wires attached to the circuit board. Find an aux cable (like a headphone jack, with the plug on both ends), cut one end off, and solder the wires into the phone's circuit board where you cut out the antenna. Now, get the input part of a headphone jack, and solder your antenna to it. Realign the antenna so you get a signal in the dish, and glue it down. Now, you can plug in your phone whenever you need a signal, without carrying the dish or needing a Bluetooth headset.
You can cut the antenna coil out of the phone and solder it to a headphone wire, doing the same for the antenna wires inside the phone. Then, put the antenna coil up on the dish, and then you can plug it into your phone when a signal is needed.
DIY Children's Carnival Style Swing Ride
Thank you for all of your help!Update on my progress. I hooked it up and it works but...It has poor performance (it isn't pushing as much air as i would have thought) and the motor definatly gets hot. It is a 2.0 amp 1/4HP motor so either the load of pushing the squirrel cage is a bit much at 120v or the current increase is too much for the windings. Might just have to try to find a different fan.
the 240 volt motor has been running.for several.years now with no problems so the answer is yes a 240 volt squirrel cage motor will run on 120 volts -at least in a fan application.
make sure the motor is squirrel cage motor. It should not have a capacitor on the side or contacts inside the end of the motor on the end opposite the shaft. If that is alright just hook the 120 volts to the red and black wires. Ground wire to the frame. Cap the neutral white since you won't need it. Remember I only tested this on a fan and it used less current than it did on 240 volts. On a machine with a varying or heavy load the results may be different. Something like a small saw or lathe should work fine.
The motor has 4 wires. Ground, Neutral, Black hot, and red hot, (the two phases to get to 240v) If you are running the fan on 120v you only have ground, neutral, and one of the "hot" wires. I'm just not sure what happens once the juice gets inside. I would hate to short something stupid before i even get it started. I'll try to Find a wiring diagram but any advice from a professional is going to basically be don't do it for liability reasons. I'm not too worried about the increased current. The fan was free so if i melt the windings i'm out zero dollars and its only going to be used when i'm in the garage so if it catches on fire hopefully i'll notice - vincedis
find a wiring diagram for your motor, vince. Find the mfg info plate, and if you can't find the original manual, Google that diagram. I'd also suggest talking to an instructor at a technical college. Maybe get a general tech manual for motors. With ac motors, it isn't the "positive leads" as you say. There is "hot" and neutral, but both switch from + to - and back. I get the feeling that you are gonna need more than casual advice. - Toga_Dan
your photo got a giggle from me. I appreciate the rapid prototyping. nice linedrawing, too. a pic is worth 1200 words.
Hate to resurect an old post but I have a similar question. When you wired the motor to your new power source did you wire both positive leads from the fan to the hot of your new voltage source? I'm going from four wires down to three and I'm not sure if i should cap one or just put them together.
Sorry to reopen a question on an older thread but I had some questions. I live in the country, there is an old satellite in the yard on the farm we purchased. For the wifi side of things you would just plug in the coax cable to the router correct? It has a LNF on it right now. Would i need to take that off? Then I could point it and see if there are any unsecured networks near me?The cell phone side I would just stand near it and move it around until I got something. There is a signal less than a half mile away, the problem Is I am surrounded by trees as I am in a national Forest. Do you think the old dish TV satellite could maybe pick up something without any modifications?
Your wind turbine is incredibly small at a diameter of just 1 metre. Maybe if you used longer blades (perhaps made of PVC pipe as it is quite light) to increase the diameter of the turbine to 3 or more metres it would produce a lot more energy.
I gave it a shot and got it to work with a perpendicular crank. It did not work until I figured out that the two cranks had to be exactly alike. Also the length of the connecting link between the two is pretty critical.
That is the first thing I tried, and it presents a few problemsproblems. Firstly, the up and down motion becomes a kind of back and forth if you attach any kind of linking to it, secondly that would just push the service crank back and forth instead of rotate it, and the second crank physically gets in the way of the connecting link.
The easiest way I see to do that would be to take the up and down action of the original crank and use it to turn a second crank that is turned 90 degrees perpendicular to the original crank.
How exactly would I go about turning the direction of the mechanism so that I get an axle 90 degree perpendicular to the original cranking action?
Id like to make something similar, except where the ending motion is a windmill instead of a piston.
