8 Ch relay power box - sharing my build progress
Hello Mycodo users, hope this is a good place to just share a build progress update. I'm planning Mycodo for my hydroponic garden. I envision a main control box which will have the raspberry pi, then other 'modules' built out separately. The modules are connected over ethernet cable, which is just cut and made into 4 wires for I2C. This lets me run things pretty freely to where I need them. This power box uses keystone jacks, so easy to swap the ethernet for another port. Inside the box is a PCF8574 breakout board, and 8Ch relay board. Tested and working well over the web. Next to build out the sensor module. Thanks for looking
Hi. That looks nice. How does the jack attach to the panel wall?
Aha. This is a 3D printed case. Are there design files online somewhere?
Not anywhere else yet, I will leave a comment here when I do. That will include a bit more assembly photos. Here is the STEP file if you are interested
edit. Oops seems its not a good filetype
I just changed the allowed file types. Try again.
Cool thanks. Here is the STEP file for the housing
ok, try now. Look slike it worked, as I was able to attach a .py file I just also allowed, which I wasn't able to before.
I like the modular concept of your setup and that's a very clean solution for the ethernet jacks!
hello, i have read your communikation about I2C Stepperadapter /Grove in the mycodo forum.
My problem is that i dont have enough money to buy all that Atlas scientific hardware.
ph kit and ec kit is absolutely necessary to get best results.
Now i have read that you wrote some code to get it running with a grove i2c stepperboard.
I would like to do it like you, saving some money and run Peristaltic pumps with steppermotors.
Can i use your code too, i have not found any other suggestion for my issue.
Hey Kyle, I have some new hardware/3D prints to share. I see your new forum... when I log in it says my username doesn't exist. Do we have to make a new account to post on your new forum?
Hello, sorry I just saw your post. Yes! please use this. I actually have it working on my end since posting that (I think I was quite a bit off back then). I just haven't posted the update code since I haven't had a chance to debug it. Here it is if you want to reference. Maybe I should figure out how to use GitHub and make a pull request or whatever it is called to share this with more people
I think this is a working file... Like I say, haven't debugged. You should be able to load it as a custom output, calibrate to your pumps, then I recommend always running them at the same speed.
Do we have to make a new account to post on your new forum?
Yes. Neither users nor posts could be moved to the new forum.
FYI, we're having a discussion about this Grove I2C Motor Driver Output module on the new forum at https://forum.kylegabriel.com/t/grove-i2c-motor-driver-support/86
