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

OldMan41, depends what is "a pot"... usually is more accurate to specify the brew ratio, instead grams of coffee. The most usual is 1:15, thus 40 grams for 600 ml of water. If the 100 grams are for one liter pot, then we are talking about 1:10 ratio.

Hey! I looked into how many grams per pot of coffee. WOW! 100grams? I only use 40+ish. Anybody else???

Thanks JackH. Just have so many other projects going, haven't taken the time to get on here. From time to time I would just glance and see what was going on.

Hi there. After reading lots of articles and watching videos, I still need help with modding my popper. The question is: is it possible to just cut 1 wire and install a dimmer to control just the heating, and leave the fan always running 100%? This is a photo of the popper:  Another angle:  (You can more clearly see the input wire, and the earth wire going up to the bean container at the top. ) This is my interpretation of elements: 1 - input cable 220v 2 - switch on/off wires (I had removed the switch to disassemble the thing) 3 - circuit board that I don't know what it's for (may be transformer?) 4 - thermo cutoff? 5 - don't know - some security fuse? 6 - these wires come from the circuit board and enter the metal base, I assume to the heating element? So I have a 1 phase dimmer, 220v 4a, and want to control the heating with it. What wire can I cut and install the dimmer on? I am inclined to cut the brown wire that comes from the #4 thermo cutter. It comes from the bottom through the circuit board and is originally the brown wire from the 220v input cable... Thanks. Duarte |

Depends how is your fan wired, taking its low voltage from a main heater split (parallel), or having its own series resistor. Only in the second case you can mount the dimmer and let fan always 100%, which is not so good, imo... This detail can't be seen from your pictures, it's internal to the blower build. To find the connection type, I would unsolder the rightmost white wire, which probability to be fan power is 90%, and measure the resistance against the other wires. The circuit board host the rectifier diodes bridge (motor is DC), and a LC filter, to cut the motor brush sparks noise. The 5 is indeed looking as a security fuse, but the placement is strange, usually this is inside the blower... so I guess is a current fuse, not thermal. |
