wind meterMy son has a project for his school. He would like to measure the wind with
six motors with difference shapes and sizes propeller. I have an old oopic A.1.7 and was wondering if we can use it to measure the wind or volts on six motors and send the data to the computer on RS232 to keep track the data on the speed and time. I am wondering if we can use Oopic to measure the wind on six motors at the same time and send the data to the computer or it is better if we use something else beside the oopic. I am computer programmer but not good on OOPic. We want to use six small motors that will fit in plastic Easter egg shell with different shape and size of propellers. We want to cover the motors from dirty and rain. We will run it for about three week. We are planning to get cheap motor from All Electronics http://www.allelectronics.com. But we are not sure what kind of motor we should get. We were thinking to get 24 VDC motor. CAT# DCM-268 We will get the propellers from the Hobby store. Some of propellers will have two and three arms and difference lenghts. We wants to look at the data and make graphic chart for each motor and know which propellor is the best etc. We will use the plastic easter egg shell to cover the motor and mount into the pvc pipe. All six motors will mount on the pvc pipe and run it at the same time. See the drawing at the bottom. We will need to use the stepping motor (X) to move where the wind direction are. We will add the vane to find the wind direction. Please give us some suggestions. o__o__o__o__o__o o=Motor with different shape propeller | X (stepping motor) | | Reid [Non-text portions of this message have been removed] |

Re: wind meterAre you talking about using the motors as DC generators and measuring the voltage to determine speed. Seems like you'd need six A2D channels, OOPic 1.7 only has 4, I believe. Perhaps you use use an i/o line to control a 3PDT relay, and measure three at a time.
Check this link for DC Motor Tachometer basics: http://team358.org/files/electrical/DC_MotorTachometer.pdf There is another method that detects the pulse generated when the commutator passes the break between the two permanent magnets, I think it employs a schmidt trigger but I couldn't find any good links. Perhaps someone else knows where to find it. With this method you'd have to count pulses from each motor - probably a little more software intensive, not usre how well the A1.7 counts pulses. Unless you're really set on using a stepper or servo to move the assembly, why not just make a big enough vane to move it directly. Hope this helps. -Will ----- Original Message ----- From: Reid Simonsen To: oopic@... Sent: Wednesday, August 27, 2008 7:59 PM Subject: [oopic] wind meter My son has a project for his school.

Re: wind meterReid You would find a much easier build with more accurate data by simply mounting props to axles and adding a simple IR encoder circuit. That would give speed and not have the motor resistance to overcome. Keep in mind that most small motors, including Johnson type, have friction and magnetism to overcome and very few give an appreciable voltage reading at such low rpms your project would produce. Slot type encoders can be had from Digi-key for less than a buck and you can make disks out of many things. Your local hobby store will have rod stock that will fit hobby props and possibly even bearings for it. When you get you project done, send me some details and pics for our upcoming robot projects webpage.

Re: Re: wind meterI have thought about that but I was not sure how to use it. I might need
some information on it like schematic and code. What about slotted opto sensor with round metal with slot or use paper with slot black and white? Which pins do we use it with sensor? Can we do six of them at the same time? I was thinking to to use plastic Easter egg and drill hole for rod to hold the propellor and out senor inside the egg to count the slots. Please give me link for schematic for sensor to OOPic and code for it.

Re: Re: wind meterOne more thing, can we use oCounter for slotted opto sensor?

Re: Re: wind meterNever mind my OOPic A1.7 do not have oCounter. Can someone give me a
suggest how can we count the turning the spin? If there is no way then I guess I will need to get upgrade version for OOPic. I have eprom burner. Where can I download new version?

Re: wind meterReid, Sorry, my bad. That version is not upgradable. I missed the version number in my initial read. We do sell a replacement PIC chip for your board for approx $29.99 USD+ s/h. You can find it here: 40 Pin Dip III Firmware <http://www.savageinnovations.com/index.php?page=shop.product_details&fl\ ypage=flypage_images.tpl&product_id=25&category_id=1&option=com_virtuema\ rt&Itemid=1> For everyone else, upgrade firmware flash is $10.00 + s/h.

Re: Re: wind meterStan,
Can you give me more information how do we connect between PC and OOPic and let PC get the value from OOPic? What kind of program do I need to run on PC to communication with OOPic to get the value. I was planning to use U shaped opto switch from old floppy drive. I am not sure how to connect it into OOPic.
