I found this old plugin lying around with dust on it and well, I thought it was really interesting . It was way out of date, and the original version was intended to add electrical functions for ship parts that back in the 0.20 days did not require electricity (but of course in 0.90 they do), such as SAS, reaction wheels, etc. I've tried contacting the original author for several months, SodiumEyes, but he has not replied and hasn't logged on to the forum since 7 May 2014. So I don't know what the rules are for that. Also see this post. But it was GPL licensed. Original post page for AmpYear is here. This is NOW the DEV THREAD. For the RELEASE Thread GO HERE. The AmpYear Power Manager makes electricity more manageable and useful. Electricity can be used in some new ways. Power Manager The manager function is attached to all probes and command pods through the power of Module Manager - thanks Sarbian (previously through a part, but now partless). The Power Manager must be ON for all subsystems to activate/work, this includes RCS & SAS. The AmpYear menu can be switched on/off via integration with Stock Toolbar or Toolbar by blizzy. Emergency Shutdown procedure - when All power is critical will activate solar panels (if attached and not in atmosphere) and shutdown non-essential parts using electricity. Saves all settings and window positions per vehicle to persistent save file. Gives %age indicators of Current Battery capacities, Electric Charge usage and generation. You can transfer charge from reserve to main batteries. Parts that produce electric charge will fill Main batteries first and then reserve batteries. In the Editor you can get indications of total power production and consumption of your vessel. You can also get a full list of all power production and consumption parts. Functions using stock toolbar or Blizzy's Toolbar (can be changed via Settings menu from the Space center). Includes correct power calculations if you have the following Mods installed (but not required for mod to function): Regolith, Near Future Electrical/Solar, KAS, RemoteTech, ScanSat, Telemachus, TAC LS, AntennaRange. Ion RCS Thrusters that use Xenon-gas and electricity for incredibly efficient RCS. Some limitations: Has half the Isp of normal Ion engines. One quarter of the thrust of normal monopropellant RCS thrusters. Available in one-way linear thruster and 5-way ION RCS block. Integrated to TechTree at ionPropulsion. Pulsed Plasma Thrusters RCS Each thruster contains a fixed amount of Teflon and uses this along with Electric Charge for incredibly efficient propulsion for small craft or maneuvering. Some limitations: Has roughly quarter the ISP of normal RCS thrusters. One eighth of the thrust of normal monopropellant RCS thrusters. Only linear thrusters are available. Integrated to TechTree at advFlightControl. See (http://en.wikipedia.org/wiki/Pulsed_plasma_thruster). TurnBooster Allows you to use electrical power to harness SAS/Reaction Wheel modules for additional turning power. Boosting them by 25%. Reserve Power Attach special batteries to your ship to save power for emergencies. Ideal for keeping your probes from dying. Power can be transferred to and from main and reserve power resources. Electrical power generators (solar panels, etc) will re-charge main power followed by reserve power when a threshold is reached. Auto-Hibernate (re-implemented in 0.13) All AmpYear functions will now continue to run during timewarp up to timestep 7x. Then AmpYear will hibernate. This is due to a bug in electriccharge generation in KSP at high timewarp. A Warning Pop-up will appear and stop warp if the ElectricCharge falls below a set percentage (configurable via the spacecenter window). Show Crew Show Crew feature - with 0.90 - I added this to show the crew and their roles rather than having to switch to the map view all the time. KabinKraziness Has been split into a separate add-on. Go here for the details. V0.18 Support for KSP 1.0.3 V0.17 Added NEW 4-way ION RCS Block. Fixed NullRef errors when active vessel is destroyed. Updated to latest version of all supported mods. V0.16a Fix ZIP File binary. Had V0.15 Binary in the zip. V0.16 bug fix in editor causing log spam. added KSP-AVC support. converted all textures to DDS format. Updated to support RemoteTech v1.6.4. Updated to support ScanSAT v12 V0.15 Support KSP 1.0.2. Fixed log spam if incorrect version of TACLS is installed. Support for: TACLS v0.11.1.20, AntennaRange V1.8, Near Future Solar V0.5.0 V0.14 Support for KSP V1.0.0. Removed support for SCANSat and Regolith (now covered by stock). Basic support for new resources parts. Deprecated z500 reserve power battery. Balanced parts to new Tech Tree. V0.13a Fixed Blizzy Toolbar and Stock AppLauncher, recompiled for correct integration with KabinKraziness. Merged install directories for AmpYear and KabinKraziness to /gamedata/REPOSoftTech/ folder. V0.13 Removed KabinKraziness. Fixed high warp rates, re-implemented auto-hibernate at high warp. V0.12e Changed default setting for the Power Manager to be ON V0.12d Fixed Vessel switching bug (save settings correctly). Kraziness balancing. Removed Auto-Hibernate and added timewarp/low power warning pop-up. Updated to latest versions of other mods. V0.12c Fixed duplicated battery parts in distribution zip file. v0.12b Merged Heater and Cooler into one Climate Control Function. More tweaks to craziness calculations. v0.12a fixed loading error. GUI improvements. Added distance from Kerbin to Craziness calc. See the Readme file for more details. License: GPL This mod includes version checking using MiniAVC. If you opt-in, it will use the internet to check whether there is a new version available. Data is only read from the internet and no personal information is sent. For a more comprehensive version checking experience, please download the KSP-AVC Plugin Install Instructions Dependency: You must have Module Manager installed. Toolbar - OPTIONAL. Source Code here Completely delete AmpYear folder from gamedata before updating. CRITICAL When installing over version 0.13a or earlier your MUST delete the following folders manually first. [kspdir]/gamedata/AmpYear/*.* [kspdir]/gamedata/KabinKraziness/*.*. Also Please ensure you have not installed previously in the wrong folder. IE: That you do not have a [kspdir]/gamedata/gamedata/AmpYear/*.* and [kspdir]/gamedata/gamedata/KabinKraziness/*.* This would occur if you unzip into the wrong folder when you install. Install BOTH the AmpYear and KabinKraziness folders from the ZIP file into your Gamedata folder for KSP. From Version 0.13a onwards this Mod will install into [kspdir]/gamedata/REPOSoftTech/AmpYear/*.* and and [kspdir]/gamedata/REPOSoftTech/KabinKraziness/*.* The included KabinKraziness KKInterfaces.DLL is a small interface to allow KabinKraziness and AmpYear to communicate. - It does nothing without the rest of KabinKraziness installed.
