nixie uhr diy

You can then raise or lower the output voltage by adjusting a block that is on the step up chip.You can either use a bench power supply, or the wall power supply I put in the parts list. Otherwise start with at least a 25k ohm resistor and adjust resistance from there. I even solder the connectors together.There are many nixie power supply chips on the market but I will focus on the one I added to the parts list in section 1.

I may be a little late for the party, but I've been wondering about the two buttons as well. Reply 1 year ago The hardest part of this is getting each digit individually and then getting the tube to display the proper digit. The input side of the step up chip will be marked with a "GND" or ground, and a hot wire input. If you end up using a wood design be careful of dirt and moisture.

The positive leg is the leg that is in the very back of the tube. Reply

Since you will be running a circuit with two 74141 chips you will need 10 LEDs' to test the circuit. Also note, you can plug the ds1307 directly into the arduino uno and set the A3 and A4 pin to high and low for power.After installing the libraries you can open some examples from the library folders to look over code and figure out how it works. From your voltage step up chip you will run a wire from your positive terminal into a bread board, then in series a resistor (15k to 25k is fine), and from there run a male to female jumper wire from the resistor to your nixie tube anode leg (the positive leg).

If you are using a bench power supply just slowly raise the volts and amperage to 12 volts while supplying the lowest amperage possible. Hi! Before moving on with the build it is a good idea to test each nixie tube at each leg to make sure it is working. My case is a larger one and it can still be a struggle to run all the wires and place everything.
Can you post a link of exactly where you for it from. Since the pcb has a 5v and gnd pour over a fairly large surface area sometimes this can cause fluctuation in the input voktage, vcc.

In the previous step I suggested using LEDs' instead of the actual nixie tube to remove the power supply and tube portions of the circuit to make trouble shooting easier, the same goes with this step. This electrical tape or heat shrink will keep your metal contacts from shorting out while your doing other stuff.Now you will need to plug the wall power supply into your step up chip. If the digit is not fully lit then you need to lower the resistance of the anode resistor. Please view the schematic from the step that was used to show how to drive two 74141 IC chips with a shift register to see the schematic.There are two main ways you can wire in your on/off switch.Method 1: Wire the on/off switch between the wall power supply and everything else.This method will turn the entire circuit off when the switch is set to the off position. The misc. 8 months ago BE CAREFUL NOT TO TOUCH THE GROUND AND HOT WIRE AT THE SAME TIME!Once you have the positive anode side of the nixie tube set up, plug a jumper wire into the ground terminal on the high voltage side of your step up chip and leave the other end unconnected. You can run the LEDs' with the arduino power.There is a great instructable on driving a single nixie tube with an arduino uno and a 74141 IC chip. I prefer shovels and clip style connectors that must be crimped onto the wire. This instructable is a compilation of everything I figured out and I am going to try and make it step by step as best as i possibly can.An overall synopsis for this project is an arduino based nixie clock that runs on a ds1307 break out board, a voltage step up chip, the arduino uno, and 14 in nixie tubes.

Plug the 5v red logic wires into your proto board. You will use one for hours, one for minutes, and one for seconds, three chips in total. Both of those buttons were an idea to have 3 buttons to change the hour, minute, and second time. This mean that depending on which 3 inputs from the arduino pins you change out you should be able to switch between seconds, minutes, and hours.UPON REQUEST Kille1992. This may also be your issue. You will want to run your power supply (or wall plug in) into your step up chip just like you did when you were setting up the voltage for the step up chip. Thanks, I already got the code working with my own pinout. im having trouble with compiling this code can you help me ?

This way the arduino stays on all the time and I just turn the tubes on and off. I am not going to post my case because I made it with a multi-million dollar manufacturing facility and the average person does not have access to this kind of equipment. After that strip about a half inch off each of the red and black wire to expose the bare copper.After you have added a connector to each end of the power supply you will need to cut two lengths of solid core wire. Currently working as a manufacturing engineer. After you have connected the wire be sure to add heat shrink or electrical tape around each wire connection so that you can not have any metal on metal contact.

Leave yourself room to work. The pins are the same though.
