Here you can read some extra information about using interrupts on Arduino. For this specific purpose, I have chosen the incremental ones.

I worked with a jigsaw to cut out the circle, and then I sand it with a sander, as you can see from the picture above. To test the encoder I have disconnected it from the breadboard and arduino. Move around and you will find it!

Thanks for your reply, I’ve a look to coord.lib and I understood the process, even if some aspects of the program are not yet quite clear for me. Maybe this comment could helps you: https://github.com/juanrmn/Arduino-Telescope-Control/blob/master/main/python/ldevice.py#L206.

Per configurare il tuo telescopio, seguire le immagini sopra. 3 – Altzmuth

This way, I believe I can prevent undesirable loads on the encoders (that can cause damages) by turning all the mechanical operation smoother. That operation is a little bit complex because involves spherical trigonometry and some time concepts (Local Sideral Time - LST).

As of version 0.10.4, Stellarium offers two ways to control a computerized telescope or telescope mount: the old client-server model: Stellarium acts as a "client" to a small stand-alone program (a "telescope server") that drives the telescope. Be sure you connect all the ground wires, including the 9V battery.Try and let me know the result. Answer Condividilo con noi! So, each time that one of this pins changes his state (meaning the encoder has moved), this special pin (through the interrupt) activate a special piece of code (ISP - Interrupt Service Routine).

Like this, you can place and remove the wheels and encoders from your telescope and, at the end, your telescope will be exactly the same telescope you bought (except a very tiny and imperceptible 4 holes...). Between 13oz and 1lb (4 sticks of butter weigh about 1lb), Target Asteroids!, Citizen CATE Experiment, Elementary school (6 - 10 years), Middle school (11 - 13 years), High school (14 - 17 years), College, Graduate students, Adults, Families, Seniors, Computers & Technology, Astronomy & Space. Questo è un passo importante:Assicurati che le tue ruote siano abbastanza strette per evitare uno scivolamento durante l'operazione! The 2 channels are not in phase. I’ve installed Python3.3 and Pyqt4 on my win7, and I try to test laser_control_main.py but I’ve an error message : >>> To help you to know the sky, there are several software's you can use and stellarium is my favorite one. Be sure you have installed the DUE drivers (SAM boards, 32 bits) - check images above. Stellarium è un software davvero bello per l'astronomia. Puoi dire: Sì! Recently, I bought a 8" Newtonian telescope that came with a Dobsonian mount. If you accomplished the previous step without any major problems, this step should be a "piece of cake"! I think I will just rebuild the entire system from the beginning.

so we broke it down into 2 tests:1) check the channel voltage to see if it flips between 0 and 3.3V.2) Make sure the arduino is "talking" to Stellarium.OK, test #2 is successful. I ask you this because I want to install a DS3231 clock module on the Arduino to calculate LST. Secondo me, un progetto fai-da-te dovrebbe essere qualcosa che puoi fare nel tuo garage usando i tuoi strumenti. The cover, as you can see, is made from a piece of acrylic. The laser points towards the celestial objects indicated from Stellarium, by using a stepper motors system. Assicurati di avere tutto in ordine (sia elettrico che meccanico) e avvia il tuo telescopio aprendo il plug-in del telescopio.

Wait a few seconds (10 seconds or so..) and a new object ( _Hello_ ) will appear somewhere at the Stellarium's sky. In my case, I have a 600 pulses encoder and a mechanical gear ratio of 15 times. Why build a gear? But my voltmeter doesn't seem to be sensitive enough to pick up the 0. Ma ho una domanda per te. 4 months ago

Ciao … Ho appena montato una montatura equatoriale per il mio telescopio e ho bisogno di aiuto per puntarla su un oggetto che ho bisogno di vedere o tracciare. So, just click, at the left side of your screen, the location manager and add your location (I mean, your observation site location...!). If your timing belt have a different perimeter, you can find the circle diameter (d) doing: d=P/pi. Add a washer and a nut (M10) to tighten the wheel. Questa operazione è un po 'complessa perché coinvolge la trigonometria sferica e alcuni concetti temporali (Local Sideral Time - LST). Your email address will not be published.

Sarà molto divertente provare a fare qualcosa di nuovo; È un buon contributo per imparare molte cose nuove (altrimenti saltate usando una soluzione pronta all'uso) come: alt-azimuth e coordinate celesti, tempo siderale locale, movimento terrestre, trigonometria sferica; Puoi controllare il tuo budget e tenerlo al di sotto di 50 USD; Il tuo telescopio sarà personalizzato in base alle tue esigenze; Il tuo telescopio diventerà "famoso" tra i tuoi amici; Se non sei interessato a spendere migliaia in una montatura, questo ti darà un grande aiuto quando inizi a puntare il tuo telescopio verso il cielo; Avere una grande comunità e un'infinità di informazioni online; È facile trovare librerie che possono aiutarti a utilizzare molte cose diverse; Puoi facilmente aggiungere molti scudi e sensori appositamente progettati per Arduino, oppure puoi adattarne altri; Per la maggior parte dei progetti, è abbastanza affidabile; È molto versatile e flessibile (porte I / O, comunicazione, ecc.
