Repository of electrical measurements from grinders

I have 4 grinders, the tools and the knowledge how to do it I've measured just about every other espresso related parameter, but for the life of me can't think why I would care.

Acaia Scale - Battery Tune-Up Program

Don't throw it away! You know you could open the thing and just replace the battery with any LiIon battery pack you buy on eBay (which they ship in all kinds of fake electronics to get around LiIon shipping restrictions). You'll need the connector so just cut the wires, solder the new ones and voila...

Rancilio Silvia heating element - what are correct readings?

200K to ground is a problem that will set off GFI outlets. And while I don't know, 50 ohms implies a 250 watt element which seems very small for an espresso machine. edit: you're in London so 500 w which might be OK. Ira

Utterly lost - I am simply unable to produce a cup of espresso

+1 on the coffee. However it might not be stale. I'm currently drinking a FRESH northern Italian style roast that required going from typical 15-18 on the Niche to 5. Pucks are goopy. [It took ½ pound to dial in on the Elektra MXC as the beans are so large and light they would not single dose and the grind...

Whoa... Measuring current on a mains connected equipment, sometimes with a chopper and/or switched mode power supply, is not a "home" multimeter thing. You need an RMS meter, that has an Amp range that will not fry the fuse (startup current may be large). Or better a clamp and an exposed wire section (or loops). You need to multiply voltage...

The Londinium R24

If you hold back the lever then it's all muscle memory. The Londinium Compressa is very much an analog machine..
