Ok had a look at the code a little closer, it seems the EL panel PWM is adjusted via pin 3, the same as the Alnitak code. So my assumption would be that the Darklight Controller along with a MOS driver, the controller should be able to operate it. I will be testing this thory this week. If so this will make this project so much easier for me to use. :)

HI Nathan and all, I recently got my Dust cover Flap device working again and wondered if it was possible to control LED lights via PWM instead of an EL panel? I use an external flat panel currently using modified arduino code for Alnitak LED driver. It uses an Arduino nano, a MOS circuit. A IRF520 MOSFET Driver Module (HCMODU0083) and a light panel, controlled via pin 3. I would like to control via the Darklight driver as it has the option for both opening a shutter and controlling the light. Currently...

Thanks Robert, much appreciated.

Hi all, Is it possible to use an existing Mysqm+ board as a Daughter board if I am only connecting a BME280 to the board? I couldn't find any reference to it in the PDF. Andrew/

Hi all, I noticed on my scope that the autofocus routine kept on failing. Being a remotely operated telescope I had to drive out to diagnose the fault. On inspection of the focuser motor it seemed the stepper motor was stalling (we all know that grinding sound) The output of the gearbox wasn't moving. I took the stepper motor home with me since I didn't have the right tools at the observatory. On inspection of the gearbox (removed from the stepper motor) I found that it was inconsistently jamming,...

Thanks for the reply Nathan, appreciate it. It looks to me I was sent the wrong servo since it will only move 180deg. I am looking into reprogramming the digital servo to see if it is possible to make it do what I want. Not liking my chances but worth a shot. I am actually putting 2 servos side by side so I have two holding the dustcap, but only 1 of them will move the other has a gear removed to act as a dummy servo. Need the extra support for the 8" scope and possibly larger in the future. I will...

Hello, I managed to get everything working but the servo will only move a maximum of 180deg. I need it to move 270 deg. When I purchased the DS3218MG servo, I had ordered the 270deg version as I need the flap to rotate to rest against the side of the telescope. When inputting different numerical values from 0 to 270 the motor still only moves to a maximum of 180deg. //adjustable variables unsigned int openPos = 0; //speed servo opens at unsigned int closePos = 270; //speed servo closes at Default...

Just an update, I was able to get the RC ESC to work with the Arduino Nano and the Darklight software. I had installed the sketch earlier but things got in the way and was unable to test. I managed to get it hooked up using the power from the ESC that usually goes to the throttle control on the aircraft, I chopped off the motor wires and ran the power to the nano and servo via a Y lead. The single Signal wire from pin 9 sent to the servo directly. I was able to move the servo 90deg open and closing,...
