| [[Howto:Build your own Panel or Cockpit - Prototype for Switch Banks using Microchip MCP23S17 ]] ||A Switch Bank supporting 256 on/off switches can be constructed using two  Microchip MCP23S17 devices and 16 resistors.||align=center style="background: yellow;"| Started
|Howto:Build your own Panel or Cockpit - Prototype for C172P Pedal and Yoke Mechanical Linkage ||The prototype will be model of the mecahnical links joining the pilot and co-pilot Yokes and Pedals||align=center style="background: none;"| Proposed
|-
|[[Howto:Build your own Panel or Cockpit - Prototype for Numeric Displays using Maxim MAX7219]] || Numeric displays are used in radios to display Frequency and in DME equipment to display distance or time.  This prototype project demonstrates the use of the Maxim Max7219 chip to display numeric data and explore power reqirements for these displays.||align=center style="background: yellow;"|Started
|-
| Prototype for Alphabetic Displays  || A couple of radios include alphabetic displays integrated with led's illuminating single letters or codes.  The letters are 1/4" and its difficult to find sixteen segment displays in that size.  A custom led segment display may be needed.  This prototype project would examine methods to produce such displays using CNC machinery.||align=center style="background: none;"|Proposed
|-
| Prototype for Air Cores ||Air cores can provide continuous motion through and beyond 360 degrees.  This prototype will examine alternative sources of air cores including purchased and hand built.  It will explore driving circuits for them.||align=center style="background: none;"|Proposed
|-
| Prototype for Stepper Motors ||Stepper motors can provide rotary motion in small increments.  This prototype will examine alternative sources of stepper motors and  explore driving circuits for them \.||align=center style="background: none;"|Proposed
|-
| Prototype for ADC Circuits || A number of Analog to digital conversions will be needed to support Volume controls and Engine controls such as the throttle.||align=center style="background: none;"|Proposed
|-
| Prototype for DAC Circuits || A number of Digital to Analog conversions will be needed to support meter movements used for engine gauges and Course Deviation Indicators.||align=center style="background: none;"|Proposed
|-
| Prototype for Air Core driven Instrument Cards  || A number instruments include a rotating cards representing a compass, barometric pressure or Attitude.  Air Cores are one solution to making the needle move. If air Cores are used, an Air Core providing more torque may be required.||align=center style="background: none;"|Proposed
|-
| Prototype for Stepper driven Instrument Cards  || A number instruments include a rotating cards representing a compass or barometric pressure or Attitude.  Stepper motors are one solution to making the cards rotate or otherwise move.||align=center style="background: none;"|Proposed
|-
| Prototype for Instrument Rotation  || An Attitude Indicator includes an element that rotates the entire display independently of the inner card representing the forward and back pitch of the aircraft.  This prototype would examine Air Cores Steppers and other motors as a means of powering the rotation.||align=center style="background: none;"|Proposed
|-
| Prototype for Rotary Encoders || A number radios have dual tuning knobs.  Detented Rotary Encoders are ideal for this purpose. ||align=center style="background: none;"|Proposed
|-
| Prototype for Magnetic Encoders || A number instruments have adjusting knobs and a need to accurately determine the actual position of a rotating card.  Magnetic encoders provide enough resolution to report position accurate to less than 1 degree.||align=center style="background: none;"|Proposed
|-
| Prototype for GPIO Expanders for Outputs || A number elements of instruments or radios elements have two states, on or off. An IO expander can provide a signal to drive the element directly or if needed, through an amplification circuit to provide more current. Most of these are LEDs, some may be solenoids moving a flag in an instrument||align=center style="background: none;"|Proposed
|-
| Prototype for Gears in the Altimiter.||An altimiter has three hands like a clock.  Unlike a clock, the gear ratios are 10:1.  We will need a way to smoothly move the three hands of the alitmiter using a stepper or Air Core.  This prototype project examines options for producing or selecting gears and whether an air core can provide the necessary power.||align=center style="background: none;"|Proposed
|-
| Prototype for Arduino to PI or Beagle Bone communication.||In order to increase the number of available IO pins and to provide better real time processing, some functions will be handled by arduinos.  This prototype will address how the communication of data between the PI and an arduino can be accomplished.||align=center style="background: none;"|Proposed
|-
| Prototype for Acquiring and delivering data to Flightgear.||This prototype will use the PHI interface to communicate data between a Node process running on a PI or Beagle Bone and Flightgear.  Testing will include cataloging the Flightgear Properties and addressing any that cannot be handled using a publish/subscribe model.  ||align=center style="background: none;"|Proposed
|-
| Prototype for Acquiring and Delivering data to Prepar3d.||This prototype will use commercial software as an interface to Prepar3d||align=center style="background: none;"|Proposed
|-
| Prototype for Acquiring and Delivering data to X-Plane.||This prototype may or may not use commercial software as an interface to X-Plane.  an open Source Solution will be preferred||align=center style="background: none;"|Proposed
|-
| Prototype for Acquiring and Delivering data from attached external peripherals of a Pi or Beagle Bone.||The prototype will address control of communication between the Node Process and external peripherals and controllers.  There may be sub-projects for prototyping specific options for the communication path||align=center style="background: none;"|Proposed
|-
|-
| Prototype for Solenoids||Solenoids may be used to move flags in specific instruments.  This prototyping project will address selection or construction of solenoids an how to drive one.||align=center style="background: none;"|Proposed
|Howto:Build your own Panel or Cockpit - Prototype for C172P Flaps Control ||The prototype will be model of the mechanical aspects of the Flaps position selection switch and the mechanism driving the flaps position indicator||align=center style="background: none;"| Proposed
|-
|-
| Prototype for Data Events||This prototype will examine represenitng changes in data and responses to such changes.  It is expected that there will be events triggering transmission of data between the hardware and the simulation program. Additionally there may be a need to feed data from the simulation hardware back to another part of the hardware. ||align=center style="background: none;"|Proposed
|Howto:Build your own Panel or Cockpit - Prototype for C172P Trim Wheel ||The prototype will be model of the mechanical aspects of the Trim Wheel the mechanism driving the trim indicator and the feedback necessary to move the trim wheel when controled by the autopilot||align=center style="background: none;"| Proposed
