Yes, unfortunately even when when one puts things clearly in writing the intended tone is always missing, and things might end up looking harsher than they were meant to be. I suggest you act proactively regarding this incident and allow those of us willing to help you to lend you a hand, if you're still willing.You are over-reacting, but since you don't have sufficient context to understand his remark, it's not too unreasonable or surprising, though you should still try to temper your responses
Ontario Cottage country for me is out at Kenora, Lake of the Woods.
What about the trays you mention, is this something that is out there or are you building this also, are you building all the mechanics or have access to a metal working or machine shop?
Max.
Are you familiar with those toddler swings that rock back and forth using a motor? Is that the kind of motion you are looking for? If so, you can probably find one of them real cheap at a Salvation Army or Goodwill store. If nothing else, it will let you see the kind of mechanism that can be used.Hey Max
I am in Ontario up in cottage country. I currently have a peerless industries 12v point to point switch for model railroad and a 5 rpm 12v motor.
There is nothing that is out there on the market as far as I have seen. I just want to make an automatic perpetual teeder todder that can drive multiple trays through a linkage.

Have a look at the windscreen wiper mechanism in your car and you will get some ideas. As you will see a crank converts rotary motion into reversing linear motion. There is absolutely no need to cause the motor direction to reverse as it is already achieved in your crank. The sweep of the crank is infinitley variable depending on the lenghts of the rods.Hi
I am looking for help in building a circuit that will make my electric motor travel in a clockwise direction then after hitting a switch travel in a counter clockwise direction. Think of it like a teeter todder, when the teeter todder hits the ground on the one side the direction of the motor switches and the teeter todder is told to travel in the opposite direction. Can anyone help me out?
Thanks

I believe that I made this very same point way back in Post #6. This is essentially a mechanical project requiring no electronics at all.Have a look at the windscreen wiper mechanism in your car and you will get some ideas.

Curious, why would you suggest all of this complexity when a geared-down motor with a two connecting rods will do the trick?OK, your a NOON and were at the other forum. Hey, I just don't have any time, but 5th graders use a PICAXE. www.picaxe.com.

That's what I would suggest.
Wbahn said:Curious, why would you suggest all of this complexity when a geared-down motor with a two connecting rods will do the trick?Because I learned a long time ago, to "brainstorm" and then take pieces from every idea. That method was further suggested in an editorial in a professional Publication, Intech, much later than when I discovered it.
Management, like you, seems very quick to discredit a particular idea and they don't understand the method,
I find usefulness in throwing out everything. Every idea has different constraints. An elegant solution is harder to come by.
An easy example is a solar panel. Space criteria dictates efficiency and weight. Domestic applications might put "a single person can handle the panel" up the ladder and on the roof as top priority.
In this case, I agree, that one of my proposed solutions is more appropriate for a larger motor.
I built and repaired stuff for use in a research facility. Modular, reliable, reuse ability, ease of repair were some of my top priorities. When I fixed stuff, i didn't want to have to fix it again, so I engineered solutions for that too. With that I used a Macintosh computer at the time and got 15+ years life out of it. The only "repair" was removing dust and a new floppy drive. The hard drive lasted 15 years and was still running.
When I fixed stuff, I never wanted to see it again.
A toxic gas safety system worked when it was supposed to, Maintenance was replacing lamps and cleaning a sensor.
Eventually, the manufacturer redesigned the product such that it trapped the heat of the lamps so the heat would break the lenses of the indicators and buttons. Their original design broke to some extent, but the new design forced me to change vendors. The manufacturer was changed at that point and LED lamps (24 VAC) were also used. I had like 200 of the broken style. Initially, the selection was cost driven. Later, it became a safety and reliability issue.
Another system was not put together by me and you could not even tell what set off the alarm unless it was continuous. It was hard to troubleshoot and many problems were loose connections and i refused to troubleshoot it until it acquired some characteristics. "they" also chose an air velocity sensor that did not have a numeric readout. A wind burst would cause the system to shut down, there was lost productivity and you could not clean the sensor preventively.
