Issues when using my DeLongi EC155m

Here is my attempt from earlier, I reduced the dose to 14g, and you can see there is still some small leaks of clear water around the head.{video}Also, you can see uneven distribution as the shot starts, I am working on that. It tasted a little bitter and sour at the same time, so I am a little unsure of...

Making my drum roaster spin faster?

Deffo don't want that magic blue smoke! I'm not sure how to find something between 24v and 48v though as those are standard. It seems like most AC to DC transformers that I've seen for these purposes is either of those. Is there some device that sits between those two numbers which you'd recommend for this purpose? Thanks again

Making my drum roaster spin faster?

OMG IT"S YOU!!! lol So I literally copied what you did with the PWM board. In fact your alteration was my inspiration (and a bit of feedback from a course I'm doing at the moment) However, I've found that on max with the PWM my motor only goes as fast as 64RPM (I counted). How did you manage to make...

Making my drum roaster spin faster?

Why not profile the heat input as do professional roasters? I've never had a gas roaster, but it worked a treat on electric. Years ago I had a yacht with a propane furnace. It was powerful, but maintained temperature poorly as the heat input was too extreme. I modified the fan control and gas input to give a nice constant...

Lelit Anna 1 gets 9 bar with a blank filter but only 4 bar with coffee

As others have said (and to summarize in a way that makes the answer very clear)--if your machine can develop 9bar against a blind PF but not against a PF loaded with grinds, then the problem is with the coffee you packed into the PF basket. Provided the distribution and tamping are OK, the most common problem is the grind...

Making my drum roaster spin faster?

Hello:Making the drum spin faster will increase the centrifugal force (which is not a force but a concept) the beans are subjected to. The result is that the beans will be pushed harder against the hot wall of the drum. This seems to be the opposite of what you want to achieve. I expect that your roaster's OEM has already...

You don't have to change the motor. Install PWM board like I "did" with my Kaldi 400. There are other versions available. You can put something like "this" in a simple plastic box and have the wire hook up to your roaster DC power input so that it's away from the heat source.

Easiest way to make rpavlis water?

I just use a scale that can read hundredths of a gram and weigh out the proper amount of potassium bicarbonate, add it to the water and shake.
