What precautions should always be taken when heating solvents on the hot plate?

Do not evaporate all of the solvent or otherwise heat a mixture to dryness on a hot plate-the glass container may crack unexpectedly. Use a medium to medium-high setting of the hot plate to heat liquids, including water. Do not use the high setting to heat low-boiling-point liquids.

Will a hot plate boil water?

How much headroom do you need for a current limiting circuit?

Any attempt to reduce the current will reduce the applied voltage. Generally your current limiting circuit will require a bit of voltage “headroom” to operate in. That means you’ll need an unregulated PSU of > 5 V and regulate it down to 5 V while monitoring the current.

How much voltage do you need for a limiting circuit?

Generally your current limiting circuit will require a bit of voltage “headroom” to operate in. That means you’ll need an unregulated PSU of > 5 V and regulate it down to 5 V while monitoring the current.
