How to get Technical Assistance from a Technical Support Moderator.

I have been wracking my brain for a few weeks on it. Many thanks in advance for any assistance I can get. How would I go about creating the PCB for this? The main question, is that I am for the most part stuck. From the outside, the layout will be identical. Using the schematics, I have produced a basic idea of what I hope to achieve, which is a rectangular hand box controller very similar to the Meade original, with a toggle and the adjustment dial for solar/lunar/sidereal tracking speed. The power cord is a six-strand coil cable terminating at a large 6-pin DIN plug. These switches are vastly different compared to the original switch buttons Meade used.Īs for the "QUARTZ/MANUAL" slider switch, it is a DPDT slider (although I have been told that a SPDT slider or toggle will work). As a result, I am having to use SPDT momentary buttons from Radio Shack (link here. No supplier I have checked with supplies these buttons. The slight problem in faithfully recreating this controller is that the hardware Meade used (namely, the buttons) is long since out of stock. In light of that, the N/S/E/W buttons are SPDT momentary pushbuttons in a normally-closed circuit.

To that end, I have sourced the original Meade wiring/component schematic from an astronomy website, plus a photo illustrating the original hand controller. Since I am an astrophotographer who actually enjoys these older units, I would like the ability to keep control of my telescope's tracking rate to ensure I can do exposures longer than five minutes (to eliminate horizontal star trailing due to drive error and to bring out the fainter deep sky objects). Today, these hand controllers are either failing due to aging electronics, or are becoming extremely hard to source. Over 10,000 LX-3 telescopes were produced in 8 and 10-inch optics, with less than around a thousand hand controllers. These drive corrector hand controllers, known as the Meade #36 Drive Corrector, were produced in a limited quantity until the end of the LX-3 production run in 1990. As part of the telescope package, Meade offered users - as an optional accessory - a manually-driven motor drive corrector which allowed the user to completely control the tracking rate ensuring the ability of exposures longer than five minutes. These telescopes upon their introduction in 1985 were considered the "cream of the crop" and were the first large-scale deep-sky astrophotography platform available to the mass consumer market.

I own a Meade LX-3/2080 Schmidt-Cassegrain telescope - with a servo motor/worm gear-driven drive base that dates back to the mid-1980s. My name is Steve Rosenow and I was referred here by a member of a car forum.īefore I begin with my question, I have a little background on my project.
