#678 Farmtek Polaris Interface Project - Keypad & Controller Part 2 - Free PCB's From PCBway
I start building my latest project, with help from http://www.PCBWay.com which sponsored the video and provided the boards to me at no cost.
I designed an interface system for the Polaris timer, this show me starting to construct the system, unfortunately I was still waiting on some parts to arrive, so I will have to do a part 3 showing the finished item.
I repair a 2011 MacBook Pro which goes to a white screen on start up.
The white screen or grey screen during boot up is usually due to a GPU failure, the 2011 failing to start up is a common problem when the GPU has failed.
I use the Tiresias GPUkiller from CMIzapper: http://defs.link/?u=416e9c

Farmtek Polaris Status Display Not Working - Water Damage Repair
I repair a Farmtek Polaris timer console which has a dead status display, I teardown the farmtek console, find several sections with liquid damage, and damaged traces, repair everything and put it back together.

I designed and build a simple 1 bit DRAM Tester so I could test 4164 and 4864 DRAM chips.
I specifically needed to test HM4864P RAM chips to repair a HP 3561A DSA.
0:00 - Intro.
1:30 - Beginning assembly of the 4164/4864 DRAM tester.
5:15 - Build completed.
7:10 - Testing power supplies.
8:01 - Initial testing of the 4164 DRAM tester.
9:08 - Discussion prior to testing a HM4864P-2 DRAM.
