Counter program in Visual Basic

Julio Costa <[email protected]> has written a simple program in Visual Basic to help him with the counting of the turns on each of the coils.

“Rather than building an electronic counter, I’ve implemented it in software, so if one has a laptop (or any computer having a printer port) where they are winding the coils, this may be useful.

It works as follows:

The number of turns on each coil is first entered.
It displays a nice big indication of the number of turns left.
It also reads out key numbers using computer-generated speech, so one may concentrate on the task at hand.
It can also automatically stop the coil winder motor (if required) when the required number of turns are complete.

It needs a simple connection of a microswitch and resistor to the printer port (I will include the drawing for this)
One may also then add a relay or triac circuit to start and stop the motor, but this is not essential, although the output for this is provided on the printer port. I will also send the diagram for this.

If you want the program and drawings you are welcome to them, and you may share them with anyone who may be interested.”

New ideas from V3

V3 have produced a nice little report from their latest workshop in Holland.

“A report of a wind turbine build course run at De Twaalf Ambachten, Holland” can be found here

There is a clever system for locating the coils in the moulds precisely.  I have often rejected the idea of using island like this in the past but the simple diagonal islands they used look rather cool and it is easy to slit the glass fibre cloth to fit them as well.

Turbine Database

Eirbyte in Ireland have opened a Turbine Database for anyone to join (you have to register) so that we can share details of our wind turbines.

Enter your details and send any feedback to Jimmy about how the database can be improved.

Otherpower workshops

Otherpower have been doing a few fun workshops this year. Here is a photo of the benchtesting of a 12 foot diameter turbine’s alternator using Dan’s old Volvo to drive it.

Upcoming courses in Washington State

I am teaching a couple of courses in WA at the end of this month.  Should be fun!
One is a Home Build workshop similar to the one we did last year in this video:

The other one is wind turbine maintenance…  an in depth look at caring for wind systems and fixing their woes.

Learn more here http://www.solarenergy.org/

I will be teaching both of these courses at Guemes island in 2 weeks from now. Here is Ian the organiser:

More photos of CAT 2010 wind turbine workshop

Thanks to Gerard Valls for this nice album of photos from the CAT wind workshop last month when we built a 2.4 metre diameter turbine (and most of a second one too).

Windpower masterclass in Tanzania

Roland Valckenborg writes:

After finishing the tower and the HughPiggott 1.8 meter somewhere halfway the master class (as you can read in the last news contribution), all participants were confident that we also could succeed with the larger model. Last week we worked on two turbines with a rotor diameter of 3.0 meter; one producing 24V and one for 48V.
