I have been trying Scott Rao Hario V60 pourover this week. 1:17 and blooming with 2 parts water the first 45 seconds then splitting the rest into 2 pours. A little stirring is included. We like it.

My brew ratio is 1:17 (exactly 59.5 g/L). That's roughly 8.5g per 5-oz cup.

I'm looking to hire someone to teach/help me to find the best roast profile for the 3 types of coffee that grow on my farm in nicaragua. I live in LA, but but could go anywhere in so cal with my Behmor for a roasting lesson. Please contact me if you're in

When your wife thinks 30 grams for a 6 cup setting is strong, you learn to drink muddy water when you are making coffee for both of you.

I use a rule of thumb of 60 grams per liter. 8 cups (1 liter, 32 oz) = 60 grams, 6 cups (3/4 liter, 24 oz) = 45 grams. 10 cups = 75 grams 12 cups = 90 grams

RobotDyn Transistor DC Relay Module
greencardigan
Has anyone tried using these modules from RobotDyn? I've had a few enquiries lately about controlling DC motors with a TC4 and PWM output and was planning to try these as a cheap/easy option.

Apparently it uses a IRF540N MOSFET which is the same as the TC4+.

Great find !
You can repurpose the small heatsink from the dimmer Grin assuming your fan motor is in the 5 Amps ballpark.

For small motors like the popper fan I am using the HW-687 board, similar control scheme, with the benefit of embedded PWM generator, thus allowing use as standalone, no need to be tethered to any computer/board.
