heating Fundamentals ExplainedDavid Williams wrote partly August eleven. “a straightforward Resolution…set up a rotating mirror….” could David or any one grow around the details,never very understand the strategy? thanks Anthony
My total-blown design and style takes advantage of a tempered glass shower door (no UV treatment method) to address the trough and galvanized pipe (solder is not going to hold up to 600+ levels)to transfer the oil.
require tips on how to alter the output to a ratio in C, for driving a stepper motor,As an example azimuth is now 271.525644 how would I multiply by 860?,For almost any information you should note,have already been employing Linux, ubuntu generally, for your earlier few years don't have any Home windows offered. Thanks.
I crafted a pc-controlled heliostat about twenty years back to light up my household. It labored excellently. I wrote appropriate program in Fundamental which I’ll give to anyone who asks. Sure. It is achievable to manage a heliostat in other means, using light-sensors or easy clock drives.
Hi Ed and David, I toyed with the concept of creating a “polar” mount with only one motor and adjusting the polar angle manually each individual number of times.
The computer was a Commodore VIC 20, which was aged even then, and had only 4.five kilobytes of memory. This system I wrote, in Commodore Simple, fitted into that Area and taken care of each of the Handle features. It even incorporated a handful of “bells and whistles”. For instance, in the evening-time the mirror was automatically parked experience downward to lessen the buildup of dust.
This is simply a prototype. Ended up I to set up it forever, I’d use a little something somewhat more rigid (the two×four has a tendency to wobble a tiny bit while in the wind).
Considering that I live in a lake, I did get a few beams of sunlight! 1 direct within the south facet of your house, one beam of sunshine mirrored with the lake: also for the south facet of your house and finaly the beam from your mirror with the north aspect!
This system will do all the calculations needed for up to two heliostats and may also send out signals as a result of the pc’s parallel port for managing the stepper motors that look what i found can change them to the right orientation.
Just one was white beadboard and was incredibly shiny, the opposite was a more powerful, stiffer foam but not as shiny. Under no circumstances experimented with them inside the sun, but never noticed the surface wrinkle either.
Your application is the most extensive I have witnessed. Thanks for contributing it. A single thought is always that depending upon the drive mechanics, there may not be a straightforward constant gear ratio among the stepper motor placement and also the heliostat angle. In my layout, one example is, the stepper motor rotation is transformed to linear movement via a leadscrew which pushes on a lever arm to rotate the heliostat.
I’ve considering the you could look here fact that witnessed similar mirrors Select as minimal as $five Every. Mine are glass, which isn't by far the most sturdy material (an assortment of mirrors could make a tempting goal for virtually any kid with a slingshot). If you will discover mirrors fabricated from acrylic or polycarbonate or An additional click for more a lot more durable content at a reasonable rate, Choose it.
Yours is far nearer to your own home so you can find absent with it. Pleasant idea utilizing foam insulation panels. I’ve been taking into consideration making an attempt that out on my heliostat. If only I could find out a method of getting silvered mylar to lie pefectly flat, or find Various other lighter mirror content as opposed to glass kinds I’m working with now.
With high winds would it not endure? Wind loading would obviousely be significant as it is a pretty big sail. since the stepper motors are Portion of the supporting ‘stays’ via the threaded rods, are they able to face up to the pushing/pulling force – i havnt utilized stepper motors ahead of and questioned whether or not they are built to handle that force.
