Errors corrected, new C4 value 24 Jan 2012 Revised for new PCB dated 1 Jan 12 08 July 2011 Errors in schematic corrected 29 May 2011 New document Nixie Tube Clock ‘Dink’ - 2 - Issue 9 (10 November 2017) www.pvelectronics.co.uk... - Page 3 RODUCTION 1. INT About the clock Nixie clock type ‘Dink’ is a Nixie Clock Driver PCB, specially designed for driving remotely-placed tubes. Connections are provided for simple wiring of tubes using a multiplex configuration. Connections may be made at the board by either screw terminals (supplied), direct solder connections or 0.1”...
- Page 4 This is not a finished product, and the person assembling the kit is responsible for ensuring that the finished product complies with any applicable local regulations governing electrical equipment, eg. UL, CE, VDE. Nixie Tube Clock ‘Dink’ - 4 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...

The fuse is a resettable type, and looks similar to the picture below, so don't confuse it with a capacitor. Nixie Tube Clock ‘Dink’ - 7 - Issue 9 (10 November 2017)
- Page 8 Don’t be alarmed if there are some extra components, as some component bags are shared between different kit types. Nixie Tube Clock ‘Dink’ - 8 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
- Page 9 Start assembly of the PCB by installing D1 and D3. Align the white band on the components with the band marked on the PCB. Then mount C1 and C2. Nixie Tube Clock ‘Dink’ - 9 - Issue 9 (10 November 2017)
- Page 10 PCB. The fuse and J1 may now be placed in position. The PCB should now look like the picture below, but with the addition of the diode D5 to the middle lead of IC1: Nixie Tube Clock ‘Dink’ - 10 - Issue 9 (10 November 2017)
- Page 11 PCB. Q1 has two pins that are joined together. The orientation of the joined pins is marked on the PCB. Nixie Tube Clock ‘Dink’ - 11 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
- Page 12 After installation of step 4.3 components, this is how the PCB should look: If your kit contains the radial inductor, use a short piece of wire to extend one lead of the inductor as shown below: Nixie Tube Clock ‘Dink’ - 12 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
- Page 13 168 and 172V. Disconnect the power supply. Finally, remove IC2 from its socket and replace on its static- protective foam. It is best kept safe until later. Nixie Tube Clock ‘Dink’ - 13 - Issue 9 (10 November 2017)
- Page 14 PCB. C4 and C5 (33pF) X1 (32.768 Khz Crystal) These are the timekeeping components: 32.768KHz crystal and two load capacitors. Nixie Tube Clock ‘Dink’ - 14 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
- Page 15 After placement of these 10 transistors, the board should look like this: Q4 – Q9 (All MPSA92) After placement of these 6 transistors, the board should look like this: Nixie Tube Clock ‘Dink’ - 15 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
- Page 16 If you are going to use LEDs for the AM / PM colon indicators then do not install R34 and R35 at this stage. Refer to step 6.2 Nixie Tube Clock ‘Dink’ - 16 - Issue 9 (10 November 2017)
- Page 17 These two LEDs should be mounted with the longer lead in the hole marked +. You can choose to mount them facing sideways like the switches, or vertically. Nixie Tube Clock ‘Dink’ - 17 - Issue 9 (10 November 2017)
- Page 18 0.1” spaced pin – terminal headers. Make up the screw terminal connectors into blocks by sliding together to attach as shown below: Nixie Tube Clock ‘Dink’ - 18 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
- Page 19 There will be just 16 wires from the tubes leading back to the PCB (10 for the cathodes and 6 for the anodes). Connect to either the screw terminals or the pin headers (via sockets / pins if you wish) Nixie Tube Clock ‘Dink’ - 19 - Issue 9 (10 November 2017)
- Page 20 Connect up the LEDs as shown below to the + and – Show Terminal Connections. Use appropriate current limiting resistors, calculated to draw no more than 20mA per LED.The LEDs are powered by 12V DC. Nixie Tube Clock ‘Dink’ - 20 - Issue 9 (10 November 2017) www.pvelectronics.co.uk...
