I'm very interested in the "baking my own cake" version. I'd like to go as far as to take Greg's source code and tweak it just to see if I can make other interesting things happen. So I'm hoping the DIY page includes exactly what all of the "ingredients" are for the cake. That's the mission . . . at least as we understand it today. The latest iteration of hardware has been published at: http://tinyurl.com/6w9vndk By re-configuring position of resistors marked Flag-1 on the board, two inputs to the uC can be either voltmeter inputs at about 22 volts full scale or discrete active pull-down inputs. The fets can be populated with any size SO-8 device. The absolute max current rating to be determined during thermal experiments the proof of concept boards which are on order. I have no immediate need for a wig-wag, but this looks like a great way to get some education at a relatively low cost. I haven't seen anyone else jump on the "me too" bandwagon, but I wanted show support for what you guys are doing. Perhaps that group will grow. I have several ideas for utilization of the hardware package being explored. Those will wait until first fruits for the wig-wag project can be harvested. Anything you care to add to the mix is encouraged and welcome. Bob . . .

    Paul, Good to see people getting interested in development for this project. I will be posting the initial C source code for the wig-wag version of the module today. This is the version that I will be using to do the hardware integration test when I get a board from Bob. It has all of the functionality needed for the wig-wag module but has only had minimal testing on a breadboard setup to verify the code. I will be doing some more testing on the breadboard and then on the initial board from Bob before I would declare it ready for prime time. Not expecting any major issues but it is my first time using the PIC micro so there might be something I missed in my several passes through the datasheet document.

    Subject: Initial Software Code for the Open Source Wig-Wag Controller
    From: "gregmchugh" <gregmchugh@aol.com>
    Here is the initial version of software for the Open Source Wig-Wag project. I am sending this out for anyone who is interested to take a look at the code as it stands today and provide feedback. This initial version is what I will be using to do testing when I get a controller board from Bob. I have done some initial testing on a breadboard and it seems to function as expected but I have not tested all of the details as yet. Feel free to provide any comments, suggestions, questions, etc. My goal is to have this as the initial starting point for an open source development and I expect improvements to come from anyone who wants to take the time to get involved. Please point out areas where it can be improved... I am putting together a description of the development tools that I used as a reference for anyone else who might want to get involved in software development for the project.

    Subject: Configuration for reset options on the PIC12F683 for
    Wig-Wag
    From: "gregmchugh" <gregmchugh@aol.com>
    Bob, I had a question on which of the reset options should be set up for the PIC12F683 on the wig-wag project besides the Power On Reset. Looking at the PIC12F683 document it wasn't obvious to me which options to enable... Should the Brown Out Reset and the Power On Timer functions be enabled for the chip? Also, did you want the external reset line (MCLR) to be enabled? I will set up the Configuration Bits as needed...

    Subject: Another Open Source controller idea
    I've been following the Open Source controller thread with some interest. I enjoy seeing the collaborative aspects of the Internet and Open Source finally expressed in Experimental-Amateur Built Aircraft. Recently I became aware of another opportunity for a commercial or open product. I share it here. Vertical Power until recently made two basic products: the VP-X and the VP-200. The VP-X, still manufactured and sold, provides full ECB protection and some extra functions: * ECB and electrical display on separate EFIS * Wig-wag automatic operation (and warmup for HID lights) * Flap and trim motor control (runaway control, variable speed and cutoff on airspeed, etc) * More convenient wiring in that there is no separate wiring to circuit breakers, and wiring to panel switches is low-current, high-gage wires. This latter provides opportunities, see below. It is a fair value for the price ($1300-$1800). VP also used to make the VP-200 until March 2012. It did all the VP-X does, plus much more. Specifically, it offered more than 10 Flight Modes, a dedicated Display Unit (for electrical and engine status), and Soft Keys in a Switch Panel. The many flight modes could be customized to turn different devices on and off automatically during different phases of flight: pre-start, start, taxi, run-up, take-off, climb, cruise, etc. With the -200 no longer sold, that leaves the only product with those features the -400, and a huge price gap between the -X and the -400: $1800 vs. $8000. Thus there is a need for an intermediate product between the -X and the -400: one that excludes the Runway Seeker technology of the -400, but includes as much of the -200 convenience as practicable. I'll call this hypothetical intermediate product the VP-X Plus. This is where the wiring of the -X comes into play: It is not necessary to create a completely separate product. The non-automated parts of the -X, that is, the usual panel switches, are controlled by low-power wiring to physical switches. Those physical switches could be replaced by an auxiliary hardware device with a small LCD screen and 4 to 6 virtual switches. The LCD screen would provide a dynamic menu and labels to the virtual switches. If the LCD screen were a touchscreen it would also serve as the virtual switches, otherwise, physical switches in a single unit, similar to the -200's Switch Panel, would be necessary. This auxiliary unit--the Plus--could also have some intelligence, enough to detect different flight regimes and operate the various circuits in a user-programmed pattern (again, like the -200). The VP-X is getting some flight data from its EFIS connection. If this information within the -X can be accessed it would be quite a help in giving the Plus the data it needs to offer flight modes. The nice thing about offering an auxiliary unit is that it could be fairly easily wired into existing VP-X configurations. The auxiliary Plus unit would be mounted so its screen is in the panel, and additional wires run from the existing physical switches to the Plus. As an auxiliary or additional unit it would not replace any existing product. If the auxiliary unit's design and software were open, then its manufacture, maintenance, and continued improvements could be done by the OBAM (EAB) community for much cheaper than a commercial product. It would offer a significant value-added to the existing commercial VP-X product. Ralph Finch Davis, CA USA QB RV-9A
