Lunar Equatorial Mount

The Lunar Equatorial Mount is a super cost-effective single-axis equatorial mount. It uses an ESP8266 as the main controller and an A4988 module as the driver. It features equatorial mount mode, time-delay mode, and star-sky time-delay mode, and offers three tracking speeds: stellar speed, lunar speed, and solar speed.

July 10, 2024 – v2.0: Almost completely refactored the firmware, changed to screen display parameters, added a wireless shutter release receiver, and can be controlled by my open-source shutter release cable. July
24, 2023 – v1.1: Adopts 16P Type-C, supports QC protocol.
 
The Moonflower Equatorial Mount is a single-axis equatorial mount inspired by the prototype equatorial mount posted by Blacklight on Tieba and the NanoLight open-source equatorial mounts (1, 2). This equatorial mount uses ESP8266 as the main controller and A4988 module as the driver. The firmware is built using ESPHome. It has a 0.96-inch screen and dial buttons, allows for completely offline parameter adjustment, and is compatible with shutter release cable systems. Only a 2.5mm to 2.5mm cable is needed to connect various shutter release cables (at least my Stande shutter release cable works). The experience is even better when used with my own designed wireless shutter release cable. It features equatorial mount mode, time-lapse mode, and star-sky time-lapse mode, with three tracking speeds: stellar speed, lunar speed, and solar speed. The time-lapse and star-sky time-lapse modes require a shutter
release cable to function. The Type-C power input uses the PD/QC 9V protocol and can be directly powered by a power bank with PD/QC 9V support. [Note: 5V can also power the stepper motor, but it's prone to losing steps at the highest speed; it works perfectly in 1x equatorial mount mode.]
Since I lack the ability to design a 3D-printed shell, the shell uses a combination of basswood board and an acrylic protective cover. 3D-printed shell designs are welcome.
 
Other detailed information and precautions can be found in the attached PDF. The attachment also includes the firmware source code (.yaml), my self-compiled firmware (.bin), and the acrylic shell file (.cdr) designed using CDR.
 
The following are sample photos taken using this equatorial mount:
In version 1.0, a single shot with a 50mm lens took 30 seconds; I wasn't quite familiar with polar alignment yet.
Version 2.0, a rougher test of polar alignment, took 5 minutes per shot.

Moonlight Wireless Shutter Cable

Possibly the most expandable and versatile wireless shutter release cable in the world.

July 10, 2024 – Equatorial mount open sourced. June
26, 2024 – Suddenly remembered I forgot to draw the RC02 battery pads. (
June 24, 2024 – Fixed a firmware bug: the zeroing interval would be cleared to 0.
) Because there are no wireless shutter release cables on the market that meet my requirements (cheap, easy to use, and highly mobile), and because I didn't want to have too many cables for the already completed equatorial mount and the upcoming electronically controlled slider, this project was born. This complete shutter release cable has three models: RC01-TX, RC01-RX, and RC02-TX, corresponding to the simplified transmitter, receiver, and intelligent transmitter, respectively. The wireless module uses a commercially available 2.4G switch module, which has the advantage of extremely simple pairing, allowing for quick pairing and multiple combinations such as one-to-one, n-to-one, and one-to-n. The intelligent version uses the ESP8266 as its main controller, and the firmware... Built with ESPHome, it features a 0.96-inch screen and buttons, allowing for completely offline parameter adjustment. The output interface uses a common three-segment 2.5mm audio jack, without any special features.
Currently, other peripherals that can be wirelessly controlled from the transmitter include: a lunar equatorial mount. Other devices are to be added later. (
Since I lack the ability to design 3D-printed shells, the shell is made of cut acrylic; 3D-printed shells are welcome for those with the capability.
Attachments include: a documentation file and an acrylic shell designed using CDR, an ESPHome configuration file (yaml), and compiled firmware (bin). Serial log printing is not enabled by default.
Additionally, the shutter release cable offers a variety of combination options.)

Surface Dial Smart Multimedia Knob

The Dial smart knob, designed using the CH582F, functions identically to the Microsoft Surface Dial.
This project is for hardware design sharing only and should not be used commercially!
Both the hardware and 3D casing have been verified; please use them with confidence.
