DIY project is not from me thus credit goes to all who contributed to this (and other) projects:

 

(1) Arduino ST4 guiding DIY

 

https://github.com/k...re/arduino-st4/  and brief intro  

https://hackaday.io/project/4386-arduino-st4-telescope-control

 

 

ASCOM driver is in the first link.

INDI driver is here: https://github.com/tliff/indi_ardust4

 

===============

 

Similar type of design (2)   can be adapted to Raspberry Pi based projects using GPIO such as

iAstroHub3 http://www.cloudynig...trophotography/ and

StarsPi http://www.cloudynig...android-device/

 

 

The key point is since these are already using Raspberry Pi based system, and there are plenty of GPIO pins,

why not just take advantage of using them for ST4 guiding interface?

 

=================================================

 

BTW a side note: ASCOM is just a common interface.

For example, the first DIY, you can find its ASCOM driver is called "Arduino ST4 Telescope driver".  (See the first link, scroll down a little...)

There are many ASCOM mount interface drivers (and some of them are in the pulse guide style) http://ascom-standar...copeDrivers.htm

 

Clear Skies!

BTW, I'd like to mention that even if the DIY is using an Arduino based solution,

for a skilled person, it is possible to get it done for less than $10 shipping included (if China sourced) or $25 if US.

However, soldering and basic electronic skill is required.

 

Using: 

Arduino pro min 5V version + 4 pcs opto isolator (PC817A or H11D1) + RJ12 cord.

Nice!  I love these electronic/astro projects!

Revised Bill of Materials (BOM)  <-- suggestion only, if China sourcing method is used

 

Arduino Pro Micro clone (about $3)

https://www.aliexpre...1859136734.html

 

4-channel opto-isolator board (about $1.40)

https://www.aliexpre...2673947386.html

 

RJ12 6P6C telephone cord 

(find it locall, need to have 6 wires inside)

 

Clear Skies!
