diesel hp VS electric hp - Glen-L.com
Saved by uncleflo on October 28th, 2019.
The Boatbuilder Connection I would like to know if,when replacing a diesel engine with an electric motor someone need to look for the same HP for the electric motor as the hp the diesel had. probably not the exact same HP, because electric motors have more torque at lower RPMs than an internal cumbustion engine

Hydro Generator
Saved by uncleflo on September 14th, 2018.
The hydro generation or “creating energy while sailing” function is an automatic feature in all Oceanvolt motors. This feature is activated by pushing the button on the Oceanvolt displays for 5 seconds. The display will automatically switch to regeneration mode showing the current generated power, RPM and time until the batteries are fully charged. With a normal folding propeller the motor kicks the blades out and centrifugal force combined with the motor controller keep the blades open. The motor controllers tune the system actively at 10 Hz which prevents the blades from closing (too much braking would close the propellers). This is continuous monitoring, the system will adjust the propeller RPM depending on the boat speed.

The Mikrokopter is powered by brushless motors. However, to use such motors the direct current of the batteries has to be converted to an triphasic alternating current) with power output controled so that the speed of the motors can be accurately controled.There are numerous brushless speed controlers available on the market. However very few are available which can fulfill the special requirements: We need brushless controlers which can accept a new throttle value very rapidly (< 0.5ms) and implement it. In addition the controler has to have an I2C bus interface.

esc - Controlling small brushless dc motors? - Electrical Engineering Stack Exchange
Saved by uncleflo on July 16th, 2014.
I'm designing an ESC with a small microcontroller running at 3.3V. The BLDC motors I have chosen are extremely small, and run best at 3.7V. I have the power supply for both of these (3.7V is VBATT, 3.3V is obtained using a buck converter). They are 3 phase, and the controller needs to be sensorless. I would like to measure RPM and current usage as well if it doesn't mean I will have an overly complicated design. All the docs I have found are great for higher voltages, and ridiculous currents (I will max out at ~5Amps at 3.7V, I don't necessarily need to design a 100V, 300A ESC). Questions I have: Is there a reference design I can follow somewhere around the net? What kind of protection circuitry should I use? How simple can I go? Are there any ICs that will simplify the circuit even further? Any other recommendations/tips/pointers?

Deluge is a new BitTorrent client, created using Python and GTK+. It is intended to bring a native, full-featured client to Linux GTK+ desktop environments such as GNOME and XFCE. It supports features such as DHT (Distributed Hash Tables), PEX (µTorrent-compatible Peer Exchange), and UPnP (Universal Plug-n-Play) that allow one to more easily share BitTorrent data even from behind a router with virtually zero configuration of port-forwarding.

I'm trying to use semanage command to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources under RHEL 6 server. But, I'm not able to find out this command and/or package name. How do I install semanage command under RedHat Enterprise Linux?

Configuration - RPM Fusion
Saved by uncleflo on August 22nd, 2012.
RPM Fusion provides software that the Fedora Project or Red Hat doesn't want to ship. That software is provided as precompiled RPMs for all current Fedora versions and Red Hat Enterprise Linux 5 and 6; you can use the RPM Fusion repositories with tools like yum and PackageKit. RPM Fusion is a merger of Dribble, Freshrpms, and Livna; our goal is to simplify end-user experience by grouping as much add-on software as possible in a single location. Also see our FoundingPrinciples.
