chris r Posted April 19, 2016 Author Share Posted April 19, 2016 Minutes work https://youtu.be/Ibdq6SD21gU Voltage reg is getting warm but hasn't hit thermal cut off yet. will do a test at work all day and see how it goes. Will probably put a bigger heat sink on/use the ammo tin as a heat sink when I eventually put it in there. I still have to figure out why the '1' of the 10 hour(s) doesn't change over. And I'll have to test/figure out why there is no switching going on in the transistors for the voltage doubler. Then I can work out what I'll be doing with the set buttons and mounting of the dekatron 6 Quote Link to comment Share on other sites More sharing options...
MichaelJFox Posted April 21, 2016 Share Posted April 21, 2016 God damn this is rad. Well done 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted April 21, 2016 Author Share Posted April 21, 2016 Thanks. I've got a few more tubes so will see what else I can make up. Next thing will probably be with a micro. I wanted this to be period correct hence all stuff on the board 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted April 21, 2016 Author Share Posted April 21, 2016 Here is more of my collection. I also have some small hitachi ones. I would like to make a thermometer with the bar graph one. still working out what else to make with the rest 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 21, 2016 Share Posted April 21, 2016 Make a vacuum gauge for one of your vehicles Edit. Or a digital dash based around these things. 1 Quote Link to comment Share on other sites More sharing options...
Ghostchips Posted April 21, 2016 Share Posted April 21, 2016 i kind of wanted to make a nixietube digital dash, it's the only era correct digital dash for pre '70s cars! 2 Quote Link to comment Share on other sites More sharing options...
chris r Posted April 21, 2016 Author Share Posted April 21, 2016 I have been pondering that. I don't know if the nixie like vibration much 1 Quote Link to comment Share on other sites More sharing options...
kempy Posted April 22, 2016 Share Posted April 22, 2016 The smaller ones are fairly robust, and cheap 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted April 22, 2016 Author Share Posted April 22, 2016 hmmm Looks like I'll have to learn how to program micros. Yes its cheating a bit buy looks easier than figuring out TTL stuff someone has beaten me to it - 1 Quote Link to comment Share on other sites More sharing options...
Lord Gruntfuttock Posted April 25, 2016 Share Posted April 25, 2016 Can anyone read russian data sheets? Still need this done? Our IT bloke is Russian... Quote Link to comment Share on other sites More sharing options...
chris r Posted April 27, 2016 Author Share Posted April 27, 2016 I have found some English info on the nixies, but thanks for the offer. Ran this overnight and all seemed well , apart from the known issues. Will have another look this weekend I've Got some more nixies on the way from russia. Will look into micro controllers/arduino and learn how to program them. Just need a suitable vehicle to put them in haha Quote Link to comment Share on other sites More sharing options...

chris r Posted October 30, 2016 Author Share Posted October 30, 2016 Sat down and spent some more hours on it. The tens weren't working properly. We thought that the transistors weren't turning off. Tested everything a few times and it was all doing everything it needs to. We ended up putting a transistor on a broad and figured that the pin out was completely different to all the data sheets we found. Sorted that and it works properly now. TLDR: the transistors didn't match their datasheet and to we had to bend the legs to get them in the correct place 2 Quote Link to comment Share on other sites More sharing options...
chris r Posted October 31, 2016 Author Share Posted October 31, 2016 I was checking everything today and found another couple of transistors that needed their legs bent. Did that and everything works! Even the dekatron! Pics/video tomorrow. Now to put it all in a case 4 Quote Link to comment Share on other sites More sharing options...
chris r Posted November 3, 2016 Author Share Posted November 3, 2016 It takes a long time to do anything at the moment. Now that everything works I can start mounting it all. I've made up some switches for setting the time, not going to use the push buttons as there isn't enough space. 6 Quote Link to comment Share on other sites More sharing options...
chris r Posted November 5, 2016 Author Share Posted November 5, 2016 I single handedly butchered a piece of ali today. Tried to make some faketina - probably should of left it brushed but got carried away. I attacked it a few times with a wire wheel in a drill to get it pitted, chucked some black on it went and found the heat gun and got the paint semi hard then wet sanded it for a bit and hit it with some clear. I'll wait to the clear has set and see how it looks tomorrow. I tested my shitty crimps on the plugs for the settings and the detatron and everything works. Tomorrow I'll attack the ammo tin and start mounting stuff. I have no idea how I'll hold a screw and get a nut on the end in a box with one hand but thats tomorrows problem. I really need a better phone/camera I 2 Quote Link to comment Share on other sites More sharing options...
chris r Posted November 11, 2016 Author Share Posted November 11, 2016 I made a bracket to hold the dekatron. Started screwing everything into the box. Fuse holder power socket and tranny are in. It was a bit of mucking around with a file for the dekatron as I lost the locking tab for the base. I'll sort out the pics when I get home Quote Link to comment Share on other sites More sharing options...
chris r Posted November 11, 2016 Author Share Posted November 11, 2016 Only the finest metal butchery will do. My excuse for the shitness is I'm doing it with my left hand Done made some purdy crimps Dekatron base mount I had to clearance it so it'd clear the tranny. I started filling the box, My (distant) English heritage came through with so many un captive nuts. Right about now I'd love a rivnut tool/set. It would of saved hours of time. I think it took me 2 or 3 hours of mucking around to get it to this stage. I quite like the hex head cap screws for some reason . 2 Quote Link to comment Share on other sites More sharing options...
chris r Posted November 12, 2016 Author Share Posted November 12, 2016 All boxed up and mostly done. The switch plate needs tweaking and mounting. Oh and I've got some edging on its way to go around the dekatron. I even guestimated the dekatron orientation correctly too 2 Quote Link to comment Share on other sites More sharing options...
