I've managed to make use of the half dozen clearish nights we've had in the last few months to sort of some of my equipment and get to grips better with the CMOS sensor, having spent years using CCDs which behave differently. Certain things have become clear as wanting doing. Remote focussing must allow for the possibility of going further than intended and running out of rack. Want imaging rig with 200mm lens - ie. 3D printed bracket and remote focus. I need a bigger filter wheel than the ZWO EFW Mini with only 5 holes - going to get the bigger one with 8 holes. Need to finish getting my ASC working to see cloud. Be very helpful if I could finish my ROR automation and reduce mud and ice hazard of going out to observatory.

I don't have a cover over the lens in daylight in my later versions and have run the ASC in full sunlight with no ill effects.

Very interesting. I have only used my ASC in full sunlight at shorter exposures but have never damaged my camera with sunlight.

Clock drive reinstalled and all working fire after a tiny tweak to the timing. Clock is now virtually silent - just a faint pulsating hum only audible if sitting quietly with no TV, radio or records. I can probably make that tiny hum quite inaudible with flexible mounting - the motor is currently fastened firmly to the partition wall (plasterboard).

I am indeed though East Devon in The Blackdown Hills a few miles NE of Honiton. Bortle 4 here also.

Welcome to Devon, Nigella 😀

I think it's high time I resurrected this project though I might finish my ASC first. BTW the rotary encoder chip is MLX90316.

Found my weather station thread HERE.

Mine is all home built. The wind vane uses a magnetic field direction sensor in an SMD chip. Measures in degrees - not that it needs anything like that level of accuracy. I must take the thead (assuming I can find it) and convert it to a Blog.

That's interesting though I already have a magnetic transducer arranged for the wind vane and simple Hall device for the anemometer. 1-wire instruments connect to an Arduino Uno plus data logging shield which also has the pressure sensor on. It all works basically - I just have to get round to finishing it.

Threads must be by far the most difficult things you can print!! Good luck.

New assembly so far.

The first aim of the whole exercise was to improve the drive for my Giant Wall Clock and remove the noisy gears and I now have the motor (NEMA17) and electronics board on the table (aka work bench) running from a bench PSU and all working fine. Turned the motor current down on the TMC2100 driver and running fine with plenty of power from 9v and 100mA. Put the motor to my ear and could just hear a faint hum. Another aim was to set up a sketch to run my ROR automation and interface to an RPi for remote control. Another aim is for an auto-winding mechanism for my Longcase Pendulum Clock. (aka Grandfather Clock)

New sketch compiled and uploaded to the Arduino Nano. Motor and control electronics board set up on table and all working fine. Turned the motor current down until the PSU showed 100mA at 9v and the NEMA17 motor still produced plenty of power. I could hear a faint hum if I put the motor to my ear.

No, it just worked 😀

Found a Nano clone and was able to upload with (Old Bootloader) so I'm a happy bunny 😀 Thank again everyone. dmesg :- [ 1870.558425] usb 4-1: new full-speed USB device number 5 using ohci-pci [ 1870.723282] usb 4-1: New USB device found, idVendor=1a86, idProduct=7523 [ 1870.723288] usb 4-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [ 1870.723291] usb 4-1: Product: USB2.0-Serial [ 1871.768896] usbcore: registered new interface driver ch341 [ 1871.768917] usbserial: USB Serial support registered for ch341-uart [ 1871.768938] ch341 4-1:1.0: ch341-uart converter detected [ 1871.791463] usb 4-1: ch341-uart converter now attached to ttyUSB0 gina@Mint-Desktop ~ $ IDE report :- Sketch uses 3896 bytes (12%) of program storage space.

I have disconnected the Nano and connected a Mega 2560 and that has compiled the sketch AND uploaded successfully. Checked dmesg for port and set to Mega 2560 and /dev/ttyACM0.

Response now. It gets past the port stage but "avrdude"programmer is not responding. That's where the trouble is.

Remind me please, where is dmesg?

On my Linux machine I have removed all older versions of the Arduino IDE and recovered the libraries I need at present. My sketch with a few extra libraries now compiles fine but neither this nor Blink will upload to either Arduino Uno or Genuine Nano with FTDI comm chip.

"/home/gina/.avrduderc" is not present. "/home/gina/arduino-1.8.10/hardware/tools/avr/etc/avrdude.conf" contains avrdude.conf

Port back to /dev/ttyS0 and now get This particular part seems it might be a problem

Changed File > Preferences to Now get
