Some transmission estimates in general and Ford Focus data:
- curb weight 2700 = 1230kg = 12kN
- torque 130 ft/lbs = 176NM
- 0 to 60 times 5.9 sec = 4.6m/s^2 : 60*1.62/3.6 / 5.9
- acceleration force = 2700/2.2 * 27/5.9 = 5600 N
- 7.5 degree slope w/7000 trailer : (2700+7000)/2.2 * 9.8 * sin(7.5*pi/180) = 5640N
- max acceleration w/7k trailer (1/3.6) : 4.6m/s^2 * 2.7 / (2.7 +7) = 1.28
- wheel diameter 15 -> C=1.2meters = 22.5 RPS @ 27meterps
- https://jalopnik.com/this-is-how-an-automatic-transmission-works-517581894
- highway speed horsepower : ~27HP : 27*750W/27m/sec = 750N
- high speed wheel torque 27mps / 1.2meters/rev = 22.5 rot_p_sec = 70rads/sec = 20e3W/70 = 285Nm (@ wheels)

- overhand is okay - so long as properly supported
- shed - 400sf - no 48" mounting, but does need tie down

SolarEdge
- support : +1.510.498.3200 9am - 8pm EST
- When connecting PV strings with power optimizers directly to a nonSolarEdge inverter without a Safety and Monitoring Interface, SafeDC must be disabled by the SolarEdge Key before connecting the string to the inverter. [1]
- Can DC output of the SMI-35 be attached (simultaneously) to multiple devices (such as the input to the SE10000A
and TriStar MPPT 600V?
- Figure 10 on Page 15 of the MAN-01-00067-2.1 discusses "SMI-Inverter
Connections". Here is shows that exactly only one SMI can be connected to a MPPT input. However the case of one SMI connected to two MPPTs or one SMI connected to a non-MPPT load and an MPPT load isn't discussed.
- P400 max power - 85V, 15A?

- Nose Levels in the Shop
- America's love affair with lawns
- Environmental Health Criteria 12: Noise, World Health Organization, 1980.
- general daytime outdoor noise levels of 55 dBA* or less, but 45 dBA to meet sleep criteria
- Don't be fooled by comparison of 65 decibels from a leaf blower to the volume of a normal conversation. You wouldn't want a noise in your home as loud as a normal conversation that you had not invited and could not control.
- According to warnings (such as Echo's "Power Blower Operators Manual"), everyone within 50 feet of a blower in use should be wearing hearing, eye, and breathing protection
"For good speech intelligibility, noise levels of less than 45 dB(A)… "[To avoid] sleep disturbance…a bedroom noise limit of 35 dB(A)… "General daytime noise levels of less than 55 dB(A)[to prevent] significant community annoyance… "To meet sleep criteria… [an outdoor level of] 45 dB(A)
- There are electric blowers on the market today that are dramatically quieter than the typical gas blower, notably, the Blowhard rated at 56 dB and produced by Manutech
- In three tests involving gas powered leaf blowers and battery powered leaf blowers, Diane cleaned the areas using rakes or brooms faster than any of the battery powered blowers and almost as fast as the gas powered leaf blowers and she did a better job in cleaning up the areas.

power supplies types
- DC 5V-20V (optional battery backup) : example is basestation, chicken house
- Universal AC isolated (85 - 250VAC) --> chicken house light controller, fan controller
- AC non-isolated (uses capacitor voltage drop) --> light controller
- low voltage isolated AC (eg 24VAC furnace)
- DC solar (<40V) - with 3V to 15V charge controller
- Battery only - with DC input for recharge ---> sensors / user interfaces
- has battery connection to allow charge from very low voltage source (TEM 20mV, solar 0.5V, Ishunt)

- MCP16301 $1.01 - 30V
- MCP16331 $1.30 - 50V
buck current source
LED buck current sources have floating load and thus can't work with battery.
- PAM2863 4.5V to 40V 2A switch 1Mhz(max)
charge controllers
- AT3681 - $0.48 500mA linear
- AAT3693 - $0.52 1.6A linear
- BQ24040
charge systems
- simplest : 5Vin -> linear charge controller ; least efficient
- simple : buck 4.2V -> linear CC ; pretty efficient (esp is Vbuck is Vback + constant)
- efficient : constant current buck, Vsns, w/CPU feedback controller
- complex : buck, Isns, CPU feedback controller
