It is a full 12 channel Reeduino with compound single channel (I've never flown sequential), V-Tail mix and Auxiliary function, using Phil's code running on a blue 328P board. Never being one to do things the easy way, I thought I'd share some of my "experiences" during the building & commissioning. 
The Case:
As a typical frugal (aka tight) modeller I re-purposed an old aluminium project case that I had in stock from a home made 2 channel radio from the mid-70's. The level of metal working skills(?) I exhibited at the time are evident in the pictures - as much a reflection of my haste as anything else!
Black automotive vinyl cladding was used to hide the many past sins. It stuck extremely well, and to my surprise even showed up the Kaptan tape overlaps, and that tape is pretty thin!!
Switches and pots:
I initially used guitar switches sourced via eBay, modified as per discussions on the previous forum. Unfortunately, these were obviously the cheap versions. I found that while fiddling on the bench, if the switch toggles were moved regularly past about 1/2 travel in either direction, the leaf spring contacts would deform (i.e. the metal in the spring contacts was too soft), making the reliability deteriorate over time and the switch action intermittent as well as feel spongy.

- with the new switches installed
Initially, I have installed the travel speed pot on the top of the case. It is mounted in the hole cut for a telescopic antenna base. When I'm comfortable with the servo travel speed, I'll probably move the pot internal.
Module mounting:
The FrSky module is mounted on its side. I utilised the ply plate glued inside the case by cutting a groove into it to insert one of the two locking tongues on the module. A ply gusset keeps the module vertical, the module then held in place by a rubber band looped around the other locking tongue to a screw in the gusset – Simple and crude but effective
.
Software:
As stated previously, Phil's Reeduino code is used. The only changes were to amend the code to use JR channel sequence and the auxiliary channel. Both easy to do following Phil's instructions in the code. I used a 3 position switch for the auxiliary channel wired the same as the main self-centering guitar switches. The auxiliary servo travels to either extreme when the switch is in the first or third positions, but stops when the switch is placed into the second/middle position, similar to the trim function.
Labels:
Taking a leaf out of Ron's book (as well as pinching some of his examples
), I've made up suitable labels for the front & rear of the Tx. When finished & installed, these will improve the Tx’s appearance noticeably as well as hiding some of the imperfections on the front of the case!

The completed Tx works exactly as it should - most satisfying
Thanks Phil for developing and sharing the code 
Hopefully, somebody may glean a useful idea or two from my experiences building my Reeduino.What to Fly it in?
It's well over 45 years since I flew with a reed set, and that was in a glider
. Consequently, I'll need to build something suitable to get the brain and fingers sufficiently coordinated with this new old Tx configuration 
. Some months back, I bought a Club Trainer fuselage from Hobby King for just a few dollars. That will be the basis for my Reed (re)Trainer. I shall post pictures & a flying report later.......
