The pins I bought on Ebay have 3 distinct regions: - There's the contact area that slips over the tube's pin, and it's springy enough to require several grams of force to remove (I'm unable to measure it, but it seems adequate). I intend to see how many pins are needed to support the weight of the tube, so that will give me an idea of the retention force. - Midsection, about 1.6mm diameter. I was planning to solder this into the PCB. I just need to be very careful no solder wicks into the region that contacts the tube-pin. - Tail-end, approximately 0.5mm diameter. I was planning to snip this off after soldering.
I've thought about having a friend 3D-print a shell to hold the pins, but it's probably overkill. Everything below the tube base, including the PCB, will be hidden inside the case. Fortunately this clock will sit on a shelf, and never moved, so it's not necessary for the nixies to be tightly gripped. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
