Creating work for myself

[Doug Griffith]

I don't know much about growing anything, but why not just use multiple lights in the room, on timers? Are the lights the costly part?

From the end user's standpoint, cost isn't a real factor. It's reducing electrical usage and limited real estate... and the lights are expensive.

You still amaze me, I think I must be from the stupid planet.... great work and fab design.

Doug,

With such low speed needed, you could use solar panels for each unit as hydroponic "tomato" lighting is typically 1000W @ 100 lm/W. That should give new meaning to "Think Green!". lol

Also, don't forget to ask for samples of the "tomatoes" that have been used on your turntable.

I am impressed!! That is some great imagengineering!! Makes me think I need to get that CNC Mill or Router purchased!!

Curious, for gear design do you "fake" it our use a program?

Cheers!

If cost is not an issue and you want ultra low power usage. I would look at a Dynamixel actuator. These are continous rotation servos with a brain. They use very little power and you can get all kinds of info from them. Position, Load, Temp, Speed. You can control them with a micro controler with no need for a stepper controller.

They have several sizes The low end ones I believe can be purchased for around $40. The large I think go for $300+


I use them for some magazine articles I wrote a while back. Here are some links from one of my web sites.

I'll check them out. Thanks for the link.

Thanks. For laser cut spur gears, I usually design with "the real thing", compensating for the laser's kerf times 2. Then create I a single smoothed out bezier curve tooth along the centerline of the overlap (the kerf offsets outwards and there is overlap where the gears mesh in the drawing). Then I replicate the single tooth around the axis. This makes for a far smoother path that still maintains contact close to that of a real spur gear. I hope that made sense.

[Darryl Jacobs]

That makes good sense. Thanks. I will have to try it that way. I usually fake the adjustment to get the thust face angles close.

Cheers!

Attached is a pic of what I do for teeth. No corners makes for smoother cutting and more distributed stress. Less control points makes the gears more manageable.

[Darryl Jacobs]

Makes good sense!! I printed a business card sample with the gears as shown elsewhere here and it took a long time to cut because of the exactness of the details in the gear design.

I will convert it to you design and report back.

Cheers!
