What are Digital Setting Circles You probably already know that setting circles are markings on a telescopes mount that help you point the telescope toward a particular object. Most telescope setting circles seem to be too small or poorly marked to be useful, though. Digital setting circles also help you point the telescope, and they are much more accurate because rotary encoders attached to the telescopes axes are used to measure the movement of the telescope, and a computer is used to monitor that movement and continuously report the direction that the telescope is pointing to the user. Secret War From The Files Of Nick Fury 1. An electronic interface sits between the rotary encoders and the computer, monitoring the rotary encoders for movement and reporting that movement to the computer via the serial port. Many commercial telescopes come equipped with digital setting circles, but commercial digital setting circles are expensive to add to telescopes that dont already have them. I designed my own digital setting circles because I didnt want to pay the steep price for a commercial system, and also because I thought itd be a fun project. My Digital Setting Circles System. The Truth About Muhammad Robert Spencer Pdf. My digital setting circles system requires four things A telescope on a mount. The type of mount GEM, Dob, etc. Two rotary encoders, one attached to each axis of the telescope mount in such a way that whenever the telescope moves including by the clock drive, if any, the rotary encoders turn.

Includes lots of whitepapers, presentations, tools, firmware, drivers, equipment, and resources. What are Digital Setting Circles You probably already know that setting circles are markings on a telescopes mount that help you point the telescope toward a. A decoder circuit that monitors the rotation of the encoders and communicates the encoder angles to a computer. This is the part of the system that Ive designed and is described here. A computer PC, Palm, or Pocket. PC that is running software that can get the encoder angles from the decoder circuit and compute the celestial coordinates at which the telescope is pointing. You probably already have the telescope and mount, or you wouldnt be interested in this project The rotary encoders can be purchased commercially, but they arent cheapexpect to pay around 5. The computer can be an old or new PC notebook, but Palm and Pocket. PC handhelds are becoming increasingly popular for use with this system. Theres a fair amount of free or inexpensive software for use with digital setting circles. That leaves the decoder circuit, and thats the part of the system that Ive designed and that you can build for yourself. The remainder of this web site is devoted to describing the decoder circuit and explaining how to build it. The links given above in the Navigation bar discuss the various aspects of this project, and I encourage you to read all of that information before you embark on building a system for yourself. Trinity Blood Bd Sub Indo here. This is a project that is not terribly difficult to build. A PC board and a preprogrammed microcontroller chip are commercially available, and with those its simply a matter of putting the electronic components in the right places on the board and soldering them in place, and constructing a few cables. I figure a couple hundred of these decoder circuits have been built over the past several years. By far the biggest source of trouble for those who build it is in soldering the components on the board. If youve never soldered before, try to find someone who can give you a lesson, or at least try to do a few practice solder joints before you start building this circuit. Soldering isnt difficult once youve seen it done and know what a good solder joint looks like.
