I was wondering why the 3.7 Hercules cant do oils?
Does it not get hot enough?
If it was used at a higher voltage may it posibly work then?
What is the resistance of the 7.4 Hercules?
It's plenty confusing for sure. Yes, this model does not produce enough heat for the job. It's big brother is running about 35 Watts, mine measures
1.6 Ohms which Omicron is OK with at 3.7 Volts but that will only develop 8.5 Watts.
Raising the voltage will raise the current and therefore power will go up by the square of the increase. Double it (to 7.4 Volts) and the current doubles. Multiply twice the current (what ever it was) by twice the voltage (to get Power in Watts if current was Amps and voltage was Volts) and we have
four times the power at twice the voltage.
The rub is poor little Omicron isn't up to all that strain it seems. And who can blame it, really. Four times the power is above and beyond as they say. Going to Persei's bigger battery and tougher electronics is the key.
G said the 3.7 Volt Hercules is running 1.2 Ohms IIRC. So that's 3.7/1.2 for 3 Amps. This times 3.7 Volts means 11.5 Watts. Remember these are calculated values. Hot off the charger will likely be a little more, the average a bit less since the supply won't put out the expected 3.7 (or 7.4 depending) Volts for a host of 'small' reasons. This power is just outside the normal 2.5 Amp maximum for the design which is why they go out over time and need the improved version still to come to be used full time this way. Getting enough power to do herbs is 'pushing the envelope' just a bit too far.
This is a tough nut to crack (obviously), which is why G and D9 put in the big hours to get this far.
FWIW I wonder what he's got up his sleeve to get it to fly with Ophos (can't upgrade the head there....). That should prove interesting as well.
Hope this helps at least a bit?
