Freed-Eismann NR-12 first signal !
I just powered up the NR-12 receiver. This is the first time in over 50 years that it has been powered up. I haven't touched or repaired anything in the radio yet but it does need some cleaning for sure.

We have had over 42 inches of rain since October 1, this video is from the morning of January 14 during a storm. Fortunately I have been able to keep the drains open and everything is holding up. So far so good.

mad skills, but a bit confused as to why we're re-inventing the wheel.
Why 6 pins for each digit, charlieplexing should reduce that to 4. (n^2 - n)
Yes, what you are saying is true - with 4 pins you could turn on any 1 LED segment. The 6 pins are also mechanical, holding the ends of each segment. Also, with 6 pins, it can make any number digit without multiplexing.
@@jayhamlin9991 0:58 I can see how each segment can be turned on at a time, but how would you make the digit "8" without multiplexing? If pin 5 is high and pin 2 is low, do you mean make pin 5 high, make pin 2 low and the rest high impedance? I think that might work, though current would be split down some paths. It looks like you still multiplexed each segment, but maybe you designed for the possibility of doing it differently.
Ok, you are right, you got me. Enough time passed that I forgot how it was done. Only 1 segment at a time is turned on and the digits are multiplexed. You can check out the code on GitHub and see how it's done. @@Enigma758
@@jayhamlin9991 Thanks for the responses and sorry for all the questions (sometimes I think too much ☺) . I think the fact that you used 6 pins made it easer to multiplex since you could simply break out each intersection. That way you wouldn't have to hard wire the additional connections required for 4 pin charlieplexing. And considering that was probably decided before you added the backing PCB, it seems like a reasonable decision. But now that I think about it again, the digits are driven by the shift registers and not the microcontroller I/O pins so you really can't do charlieplexing since you can't set an individual shift register pin to high Z. So I believe you are actually doing "traditional" multiplexing at the segment level. At any rate, you did an amazing job on the clock and it inspires me to do something similar!
Good idea. I think it is necessary to isolate the segments with partitions so that the neighboring ones do not get exposed. (There may be spelling errors, I used Google translator.)
Yes- some optical isolation would make them look better. In the final clock project I put the segments into a PCB which helped. Actually they look pretty good and the clock is still running today. If you have not seen it, please watch the clock video: ruclips.net/video/gkYBQIplHyQ/видео.htmlsi=homARCDh8_kFFHd1
When nixie tubes are very rare like chicken teeth. And when you do find they are expensive and in america and im in south africa! I have fallen in love with nixie clocks. But due to problems mentioned. Im also looking to do something similar as in video. Although a bit weard and crazy maybe. It would probably let people ask Why?.
I'm back watching your video again. Absolutely stunning result :)
But I have some questions more: you said the toaster has 2 heating elements, one top, one bottom. Are you able to turn off the top one? If not and is working, how come the barrel jack plastic is not melting away?
So, from begging to and the project took more than a year. Now, I'm not that concerned that my clocks aren't ticking, yet. :)
Very nice project, it looks awesome.
Great idea! But what they're lacking is a grid in the front face, like in the Nixie nubes
This looks pretty nice! Good work!
How cool!!
And needs new batteries
Hi I have HP97 also
Do they have a “degauss” function? I wonder why current sense probes would need those and this wouldn’t
What Honda pump is this? (Model#)
Can you send to india..
Still to much fuel in a trapped area i am no fire fighter myself but i cut back alot and was told i should cut back more don't have 50 percent bush u have
How does the filament light up? I thought it was 3D printer's filament...
LED filaments are little strips of LEDs commonly used in LED "Edison" style bulbs. Check out ruclips.net/video/NffhdAz9pc4/видео.html or search for LED filament on Amazon or AliExpress.
Youre getting some distance with that but question whats the psi from the pump when run ing at full power ? I have 2 2" transfer pumps that when ran in series get some nasty pressure but i dont have enough output as i want. There 195gpm max i want to run a 200 series big gun but i dont have enough with those
Bro profit plz link
The local leftys who live there acted like they never saw a man do work. So they all came out and stood in the way watching in awe. Also the company men did not speak english XD normal for California huh. What a complete let down and joke this video was. Sickening to see you try to soften the blow of illegals pouring over our border on a daily basis. How many Americans must die and suffer before you think America is good enough again?
Very nice job, Jay! We lived on Miracle Lane just up from Mary Alice.
NICE 😃 I looked through your later videos to see if you FOUND something fun to do with these… but didn't find any more videos on them. (Just looking for ideas for MY spaghetti ☺️)
They are very fun to play with :)
Absolutely brilliant idea, actually far more interesting than a conventional NIXIE clock
Jay & other amateurs. Do your homework before buying and using a pump like this. First off, I cringed when you shut off the nozzle with the pump running. You could have blown the pump seals. Put a PSI relief valve before the hose connection. Some of these pumps will not tolerate any debris except if VERY FINE. If it's a "semi-trash" pump the debris can be a bit larger maybe less than 1/2". If it's a trash pump you won't get near enough PSI. Debris clogs the vanes in the pump reducing its efficiency. Always research the pump curve. This shows you GPM @ Head. PSI is another function. PSI decreases as the flow GPM increases. In my case my pump is dual purpose. 30 sprinkler heads plus 1.5" fire hose. In case of a fire I can run my perimeter spklrs and 1 or 2 fire hoses. Hope this helps
Amazing, thank you! :)
Nice! Wonder if you could move the front pads to the rear and hide all the solder joints. The front would look super clean. I should try making a clock with these filaments.
Very neat clock. I love it!
pup !
kindly please share with us the model and psi (pressure) ...tq
Great Video Jay ! What a SPOOKY line of work . The Chopper pilot is very skilled !
no need for arduino to do that. Only with wires and resistors you can make a small hard wired decoder.
Which model is this?
Question: I got those LED filaments here, where is the anode where the cathode part ? One end has a small hole in it, so it is definitely A/C but hardly to know which. Dont want to waste any filements, so any hint is great
the end with the small hole is the positive (anode) side. They are sold as "3 Volt" filaments but I found they work good at 30mA which was about 2.72 Volts.
@@jayhamlin9991 That does the trick. Working (technically) now, however some faults, maybe you got an idea: seconds 01256789 working , but 3 is without the lower line, it's on when 4. Would assume something with the logic. Or do you got an idea on how to troubleshoot the display ?
actually, i noticed that the lower line (_) is reversed in anode/cathode, e.g. your old design is slightly different to the use. Question would be: How can i easy test out everthing (like console i type in a number and it gets displayed ? would help others as well.
@@JanCzmok I think I know the answer but I have not had time to confirm, this is what I think it is. If you are using the Arduino charlie7 code, I had an early prototype with the lower line LED diode reversed. I think the code in gitHub is for this prototype. Sorry. We need to swap the '1' and '0' for the lower line. I can look at it tomorrow .
I did not write any test code other than the counting 0-9 in the code. It is only Arduino, you could easily add a console function.
Amaizing project! Looks very nice! 😁
Nice work. But the coolest (nixie) clock by far is "the Rad Master 1000" by coreWeaver: ruclips.net/video/F5FGLUkp3rM/видео.html
Wonder what it would look like with a nixie-like mesh screen in front of the digits inside the tubes to diffuse the light
Great idea to use those LED filaments for it and the clock came together beautifully. Well done!
Really cool project, I love the idea of using these LEDs ! Good job
they actually look more like numitron tube's
Those are a thing of beauty. Really well made and I love the idea. Thanks for sharing.
Thank you very much!
Update?
Agreed, I need to make a video showing the finished system. It is complete and working. Soon.
Wow, those After Dark PCB's look so freaking amazing. Good job on the clock!
I really like OSHPark. I didn't document the soldering but I used a stencil and reflowed the board in a Black & Decker toaster oven.
Awesome project man, Ive been searching for an authentic looking nixie-style led clock for over a year now to no avail and this project is the closest ive seen, far better than the edge-illuminated laser engraved acrylic ones you see everywhere. I might actually have to give this a try myself! I think the floating digits looked very snazzy though, maybe I will give them a try and see how far I can get
I can't wait to see what you come up with.
Hi Jay! Been looking over Doug's shoulder at your fascinating work on the NIXIE tube clock. I'm a total layman on electronics, but love learning and creativity. The way you envision and develop a concept like this is inspiring. Grateful that I get this glimpse into your talent and mastery! You, Sir, are fun to follow! All the best, Chuck Heinrich
Very cool!
It's a bad idea to run your pump for more than a few moments with no water moving through it. Excessive wear of internal parts will happen.
