Measured the potential difference of all the components in a circuit and it adds up to the voltage of the battery. Dropped the resistance in the potentiometer, and the PD in the resistor in the circuit jumped up. Everything still adds up to voltage of battery. I assume it means the resistor is then doing more work? Super cool!
Sounds like a plan to me – I do that sometimes – just spin up a $5/month VPS with Digital Ocean, play around with something, then tear it down again if it doesn’t work out (or keep it if it does!)
Good luck with the projects — look forward to hearing how they go. 🙂
A 9V battery, some test leads and croc clips, a resistor and an LED. I am way more excited about this LED lighting up than perhaps I would have expected to be. This is loads of fun.
I’m even enjoying measuring the resistance of resistors with the multimeter and cross-checking against the reading from the coloured bands.
Having loads of fun with Make:Electronics so far. Have measured the resistance of my tongue, dunked my multimeter probes in a glass of water, and shorted a (1.5v) battery. Good stuff.

I’m going to set up a FreedomBox. I have an old Raspberry Pi B+ knocking around. FreedomBox works on it apparently (https://wiki.debian.org/FreedomBox/Hardware/RaspberryPi) but I’m wondering if it’s going to be a bit low-spec to do much with it. Anyone know? My main uses to begin will probably be syncthing, Quassel, Radicale, and OpenVPN.
