Re: [neonixie-l] Driving Nixies and LEDs at the same time ...
Am 03.12.2013 18:45, schrieb John Rehwinkel: Before I damage something, it is possible to use a single Supertex HV5812 to drive nixie tubes and LEDs (for color effects) simultaneously? Of course, I am planning to use current limit resistors for the LEDs and the Nixie circuit I am planning to use is exactly what I have used in the past, except that this time I will be using the Supertex part instead of the 71141 or the russian counterpart. Thanks in advance. You'll have to use pretty high current limiting resistors on the LEDs, as that part is only rated to sink 3.5mA max, which isn't much for an LED. It would be tricky to dim LEDs with it, so it would be pretty much on/off. However, it seems to me that it would work. - John You can use this circuit when you use Output high I_OUT:max = -25mA ... but you musst drive the Led with a extra circuit and 5V on HV ... and LED-Resistor. - Jens -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] How to get IV-11 VFD tubes properly aligned on protoboard
I received my IV-11 tubes today and I was trying to put them on a board, a prototyping board. The best way to insert them (that I found) was the one in the attachment. But I noticed that the tubes would be ever so slightly tilted, aprox 1-2 mm over the whole tube. Does anyone have a better way to place them? I have added an empty piece of protoboard next to my best try in case someone wants to show his/her idea. My alternative plan is to just bend the wires a little but I don't want to stress the connection to the glass feedthrough (?) too much. For those who followed my previous thread(s) currently I am only waiting for the PLCC to dip sockets and DC-DC convertors, the rest is here. And a friend is helping me with the arduino code. :) -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Gideon, The wires are flexible. Don't worry about stressing the glass.

Re: [neonixie-l] How to get IV-11 VFD tubes properly aligned on protoboard
Yep, exactly. I can take a picture of how I place them, but basically it ends up being a sort of square or rectangle. I leave about a centimeter of lead above the protoboard so that the tube can be gently twisted the right way. -Adam On 12/4/2013 2:26 PM, David Forbes wrote: Gideon, The wires are flexible.

Re: [neonixie-l] How to get IV-11 VFD tubes properly aligned on protoboard
Ok I'll see wether i can place them a bit higher as I was pushing them almost against the pcb. -- You received this message because you are subscribed to the Google Groups neonixie-l group.
