Direct driven nixie clock don't have to be brighter. Many multiplexed ones are driven with higher pulse current - which is still acceptable according to datasheets (it was acceptable to drive nixies with half-wave rectified mains! Something that no one with brains would design today). It again comes to decision of constructor - better visibility or undercurrenting to increase life*. I personally have built only one clock, with Z566M tubes, which are in my opinion the most beautuful tubes - right proportions, high quality, curved digits and great thickness of gas coating around digits. I am multiplexing them at 4mA (datasheets suggest 4,5mA in direct drive) and digits are barely visible in strong sunlight - as spring is around the corner, I will probably adjust it to around 8-10mA, because more and more sun will come to my room :) *I am not sure if strong undercurrenting will increase tube life. I aim at point between lowest and average value in datasheet.
Keith, I would suggest searching for top view tube clocks. They are generally cheaper, but in my opinion they look as good as side view tubes, they are less likely to be broken and these can actually look good with LED underlight (this is a phenomena I can't understand - in tube clock, the nixies should be the main thing that catches your eye). There is a small company in Poland, which creates beautiful clocks using Polish end view tubes: LC-513 and LC-516, which are (as far as I know) interchangeable with IN-1 and Z560M, respectively. These clocks can be purchased as finished products or as kits. http://www.electronixclock.pl/nasze-zegary/zegary-gotowe/electronixclock-4xlc516/ http://www.electronixclock.pl/nasze-zegary/zegary-gotowe/electronixclock-4xlc513/ Both cost about 125$ without shipping. Unfortunately, the site is in Polish only - but if you want, I can try to get them to contact with you. These clocks are well documented, as they are open source projects (again, documentation is avaible only on Polish forum elektroda.pl, I will find links and help to translate them if needed). If not those clocks, try searching for Z560M clocks - those are beautiful and cheap tubes (here in Poland about 2,5$ for used tube) W dniu czwartek, 16 marca 2017 15:34:05 UTC+1 użytkownik Paul Andrews napisał: > > I like the clocks from these guys: > http://www.ebay.com/usr/gra_and_afch_2?_trksid=p2053788.m1543.l2754 They > are direct drive so as bright as they can be.
