Been really busy of late so haven't had time to rev the design or tweak anything 
I'm spending some time cleaning up my shop and retooling a few things in the next few weeks so should be able to knock a bunch of things out after that, so I can get updated boards after that point. |
I bought the cheapest 3 pack I could find off aliexpress and used them for an AWC setup from my basement to the tank upstairs with them mounted in the basement, so noise wasn't a concern. Now I'm looking for something a little quieter with more precision for 2 part dosing from underneath the tank where noise matters a little more.
Do you have any preference for one pump over another? There are so many choices on aliexpress and even amazon that it's hard to decide. I figure if you've already looked at a few, even briefly, i'd rather pick one based on your opinion than on nothing at all.
