ARO Slow Feeder™ | Electric Variable-Speed Coffee Bean Feeder

Weak magnets

It works , does the job but the magnets are not too strong , and it is very tall and if you have a low upper cabinet it may not fit, it also all plastic , I hoped it will have more metal parts. Generally better than cremaloop plastic one. It is also cheaper and include the bellow in original price.

Slow Feeder for Olympia Express Moca SD

Where to start... I didn't realize 3D printing could be this intricate or finely detailed. If a CNC machine and a 3D printer had offspring this would be it! For my first step into automated slow feeding I did not intend to spend what would purchase a decent grinder. This looked promising. Was curious about the possibilities of acquiring one for my Olympia Express Moca SD. Took some accurate micrometer measurements with photos and emailed them to Nate on a Tuesday afternoon. Response within a couple of hours. Said he would make 3 prototype adapters of slightly different diameter to determine what would be a good fit. Told me he should have them created and ready to ship by the end of the week. He actually dropped them off to be shipped the next day, had them 3 days later! The first adapter I tried fit like a glove. It thunked firmly in place on the hopper. Since the Moca SD hopper has multiple functions for actuating the grinder, replacing the hopper with a slow feeder isn't really feasible, so it goes on top. The Moca SD has a small footprint, but it is kind of tall. Mine is sitting on top of a knockbox drawer, so even taller. I leave the adapter on the grinder, the slow feeder sitting next to it. I use the slow feeder as a dosing cup on my scale, then click it in place on the hopper and grind away. I've always been reluctant to use RDT unless it's really necessary. With this setup I'm not, and experiencing either no retention or occasionally 0.1g (I think all grinders have some retention, but I think an exchange is happening- a very small amount of grinds are expelled when using the bellows). I'm not enamored with the portafilter fork on the Moca SD. I fabricated a small shelf that allows me to rest a bottomless portafilter or a blind shaker on it. With a dosing funnel on the portafilter, the obviously slow feeding allows me to move the portafilter around and evenly (mostly) distribute the coffee in the basket, so the time invested during grinding cuts down in some puck prep later. After the dose is in the basket I remove the slow feeder from the adapter and place it where it will sit until the next use, at the same time verifying that I turned off the slow feeder. I'm now dialing in settings, speeds and times with different coffees and baskets. Some gadgets and techniques added to your workflow end up having questionable or no positive benefit. The first shot I pulled was clearly different than without, with the shot revealing some new flavors and characteristics (good ones in my opinion!). I don't have a sophisticated palate, I just know what I like. I would like to improve that, but I'm the only one that has to be pleased with my results. I'm 72 and not really interested in becoming an "influencer". However, when someone provides exceptional service and what I consider to be a good product with value that is beneficial to me, I think they deserve credit for it. Everyone has their own opinions regarding coffee and coffee equipment. This is one of mine :-).

I am very happy with the device. Even though it is 3D printed, it is well made. The most important thing is the result in the cup, and it is excellent. The best coffee I have ever had.
