Just for fun, I built a dual e-nail setup using the standard design and the MYPIN TA4 PIDs and the new XLR connector. Got the programing done and its working nearly as good as my D-nail original unit.
Going to build a triple for my buddy's dab bar where we hang alot. Nice glass bar in a semicircle made out of glass. Figure setting up three stations with complete control would help avoid passing pieces around. Also, easy to compare nail step-ups or even different glass itself. Typically run a 20mm dish, 18mm female quartz nail on one rig and a Omni nail from Santa Crus Shredder using a 10mm coil and the standard D-nail base. Tried out the original rev 1.1 TI nail (10mm coil) and the new 20mm dish rev 1.2 TI. For TI nail use the Omni nail is the best so far. Just bought the top section from SCS and use the original D-nail base and coil. Also bought the new rev 1.2 top since I use a 20mm coil on the quartz. About $450 out of pocket with coils and 2 nails.
Also bought the cheaper coils from AliExpress.com. Comes pre-wired with the XLR male plug wired compatible to the production D-nail XLR female panel connector. Only $60 ea. Uses the same sleeve etc. only thing takes time to get and shipping is a bit high. $16, then $6 for each additional.
