Re: [neonixie-l] Need help with a 230IK1 IC (nixie driver)
I've been designing IC's for over 30 years now, and this is definitely one of the most unusual I've ever seen. This appears to be from the 1976 to 1980 timeframe, and having to use multiple die to implement such a simple logic function shows that the former USSR was behind in their process technology. Intel's 8080 CPU debuted in 1974 and had 4500 transistors in a single die inside a 40-pin package; the K230IK1 was at most a few hundred transistors and required at least 7 die (maybe more; photo is chopped-off). A lot of work went into assembling these; I hope you can get some of them running. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Re: [neonixie-l] Need help with a 230IK1 IC (nixie driver)
Thanks everyone for the help! I can start some tests with this info. I'm going to order a couple 1.25mm pitch FPC connectors from digikey first so I can connect to the IC without soldering to it. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

[neonixie-l] A simple mod for Passive IR sensors... A toggle switch setting clock to: ON / PIR-controlled / Off
Hi folks, This is a *VERY* simple modification I'm making to the PIR sensors on my clocks. I was going to add this as a response to Edwards build thread but thought it might be of more general interest... The mod is simple and I'm finding it quite useful. I've added a center-off SPDT toggle switch on my Passive IR sensor modules with positions for "On", "PIR controlled" and "Off". The switch allows me to put clocks in my shop space to sleep when I'm working for a time with my back to the clocks... allows me to easily test PIR response on controllers, etc. See the attached photo for the details. Label added for clarity. Note that the PV Electronics PIR module case top piece shown has an extra hole added above the second PIR module trim pot to allow me to adjust the module hold-on time. I've retrofit some of my clocks with HV power supply disable lines under PIR control. These modified clocks need the PIR module to control on-time when activated. I also change a cap from 10 nF to 100 nF on the PIR module I use extending the max hold-on time to about 42 minutes... the cap is connected to pin 4 of the BIS0001 IC. Modules differ in layout so I won't post a photo showing the cap location... The BIS0001 data sheet details the function of this cap.

[neonixie-l] PV Electronics R568 Clock Project With Black R|Z568M Nixie Tubes
I am starting my new clock project and will be posting my build here. For now this is what I will be ordering. PV Electronics R568 Clock kit with black colon tubes 6 Black R|Z568M Nixie Tubes PIR Kit Azevedo NWTS with black case I need to know what high quality 2 amp power supply you would recommend to get? With MichaelB help I have the preliminary stand design and color worked out and waiting till I get the clock kit to make the final drawings and prints. His input really helped quite a bit as all the LED's, Switches, Power connector, GPS and PIR connectors will be mounted in the stand instead of the PCB board. Jeff Walton is also helping me out with the NWTS and I thank him for that:) Stay tuned and add any info that might help me out on this build.

Re: [neonixie-l] Need help with a 230IK1 IC (nixie driver)
Hello ZY. Nice find those chips. I cannot help with a direct translation from Russian, but rather suggest a procedure that has helped me several times with the Russian datasheets: Google Translate on the smartphone (tested on Android). It lets you point at a text with the smartphone's camera, you highlight the text and it provides a translation almost on the fly. Actually, if you download locally text tiles for the source language it does it live, replacing the original text with the destination language. Amazingly scary to me. For these highly specialised texts you may need to do a bit of interpretation of some words, but I noticed it is giving better results every time I use it. I usually have it translate into English. HTH, Paolo PS: yes, 49&50 are translated as Supply voltage. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
