Hello EZ Robot! Meet Dusty, he is a omnibot torso and I currently have the choice of robbie at head or a omnibot done where you can see inside. He will handle a few basic functions and us made more simple than his big brother Jarvis.
- He can vacuum (which is loud) with power brush and impeller
- He can "sweep" nearly silent by running the power brush at a reduced voltage and a small DC blower providing low level auction. 3.dusty will have two germicidal bulbs ,.one facing downward to the floor and another behind intake fans that not only cool electronics but it pulls air through a Honeywell two stage carbon filter. 4.dusty has 4 build in filters foam pre filter , and 3 carbon filters.
- He will have a camera on pan tilt bracket. He will be controlled by Bluetooth or wifi.
- Long runtime , 2 x 12v 7ah batteries.
Any other suggestions guys?

Yes gunner. Got a nice app for me? Lol
@Gunner woops I forgot to check my spec sheet . 1-1.5 v forward current. 5 volt reverse current and 50ma current draw. So my wiring in the drawing is not even close. Lol. I remembered somthing was different about IR leds.
How did you wire yours gunner?
Hahahha Gunner I was thinking the same thing about Josh's stove... :o)
Dusty has come a long way. He looks good beside his big brother.
@Josh, you are correct that at 2.5v forward voltage each, then 5 in series would work with 12.5v without a resistor, but I believe they would overload at just 13v
Whereas with even a 10 ohm resistor, you have almost full brightness and a bit of protection in case your battery's are right full.If you have an Android device, then an app called EveryCircuit is great at testing out the what-ifs without releasing the magic smoke
@sam Thanks Sam ! Yes I do cook not always everyday but it happens. Im trying to contain projects mostly to the kitchen table now lol.
@gunner Oh and gunner the leds are 1.5v and 50ma so I gotta figure out somthing. How many leds are you using?
At 1.5v FV I would sujest keepping them at 6 LED's per rung (9v FV max) with a resistor to make up the remaining load at 13v. 6*1.5v=9v (13v-9v)/.02A = 200 ohm resistor per rung. This of course assumes they are still rated for 20mA
EDIT, which I just noted they are not
Thus I believe an 80 ohm resistor is the requirement.
