Posted by: charles jones Feb 11 2016, 06:23 PM I remember seeing an orrery built into a large cabinet with viewing from a window on one side. The solar system was at a slight angle - not edge on but not from an over head view. It was lit with black light. Therefore, you couldn't see any moving rods or gears, just the bright planets in fluorescent colors.
It was very effective.
For some reason, I think I was told Spitz manufactured this.

You are correct.

Posted by: Ron Walker May 17 2020, 10:22 AM QUOTE(charles jones @ May 16 2020, 07:50 PM) * Not sure where to post this.....Ron, how much do you remember about upgrading your A3P with timing belts? Can't find the original thread, but had copied it several years back. One of the two moon analog motors obviously rotated in different directions because they were tied together with two gears. But of the others, did all the motors rotate in the same direction? You added bevel gears to turn the "phase" projector. Wouldn't that have changed the direction? Although you mentioned something about two 40 tooth gears. Not shown, but were they to again change the direction back? Do you remember any to this? www.observatorycentral.com/index.php?showtopic=2263You are correct, only the one extra moon motor ran in reverse. Bevel gears are strange in that they actually can turn in the same direction. Think of a rod turning clockwise. Now put in a bevel gear so that all of the teeth of one touch all of the teeth of the other and both shafts lineup. Both shafts still turn clockwise. Now pivit one of the shafts but still hold contact on one edge. Both shafts still turn clockwise. Only if you offset the shafts so that the left edge of one engages the right side of the other will you get the change in direction common with most gear interactions. I would have to review or you could tell me which post your referring too. I'm thinking it was 40 tooth timing belt gears which when connected with timing belts would not reverse direction. I will copy this over to that thread.

This is the copy over and is now in the right place. Going to the head of this thread is.

I'm not sure how they count those things. There are over 150 posts in this thread. If they count each post view then only two people need to review each post once. But then each page offers up 15 different posts so how would it know how many were read. It probably counts a view each time someone visits which makes for good viewership. If we take a day like Thursday the 25th there were 312 visits to the web site. Of those 276 went on to visit the various pages. How many individuals went on to visit how many pages is anyone's guess but the numbers are close enough together to indicate that a substantial number of visitors went on to read some of the material. I just am curious why we have no new members.

If its visits to the site, then you are doing real well. I still think though alot of people may not necessarily be involved in the hobby, they are surfing interesting sounding boards rather. But again, you are informing people that such a thing exists. I think its wise to have it open for perusing without joining for this reason. I know its alot of work, but maybe several more 'homemade' threads might spark more interest, the salvaged commercial end of the hobby may be beyond most's hobby budget? I think you've got the right mindset now though, if you think of posting an old thread here as similar to giving a show to visitors, then the two are similar. Have you ever thought of converting one of your shows into something could translate here? Collect those clicks! Even when my podcast gets 1 lone view from some oddball state, I at least know they were exposed to something perhaps new to them, even if just for a moment.

I did open this up to anyone to view but must be a member to post. There was a huge uptick as there is whenever I add a major post. Also, Most Users Online: 66 (Aug 18, 2022 at 4:01pm). I don't know how people who are not members found out that viewing was open to all but I guess some did. Perhaps search engines were given a ping and changed how they present this site. I will continue to add threads.
