Wire Wrap circuit construction, from scratch: Part 4 - Cathode drivers

Part 4 of a five? part series showing wire wrap construction, start to finish. These are long videos, with just a few section fast forwarded but no assembly omitted. This has a mix or wire wrap interconnected with discrete component, for the seven segment LED cathode drivers. The next part should complete the electrical build and be ready for programming. ------------------- I have been asked to demonstrate the entire assembly of a project using wire wrapping; this has taken a while as I normally only use it for complex, multi-IC MCU or logic boards. However I've been intending to do a demo of multiplexing displays - and I realised that could be modified to build using wire wrap sockets. This series shows the whole process, from bare stripboard to completion. I've created a new playlist for the wire wrap videos, here:    • Wire Wrap principles and construction   Chapters: 00:00:00 Transistor locations 00:00:40 Fitting & soldering transistors 00:07:05 Trimming the excess leads 00:08:45 Emitter common ground wiring 00:11:07 Wiring, transistor bases to wire wrap pins 00:24:45 And the transistor collectors to display cathodes 00:31:25 Review of what parts & connections are where 00:32:00 Which way to fit the MCU module??? 00:32:40 Sidetrack - ST-Link wiring mod 00:33:32 Decisions! 00:34:15 Sidetrack - fake stackable headers 00:35:40 First MCU connections 00:41:25 Checking pins counts match 00:42:00 What's left to do 00:42:22 End of this section
