A possibly authorized fix for the Boeing 737 MAX missing indicator option. Ours works!

Originally released online and at the AP at DEF CON 28 in 2020.

Too soon?

For more information. see https://dc28.whiskeypirates.com/

Here's the assembly guide and schematic.

This is the new DC28 v2 variant. For the original DC27 AOA (kit only), see here. For a fully assembled version, see here.

• We've gone digital - powered by WP CHIP advanced AOA logic!
• Still more reliable than Boeing equipment as shipped

• We've gone to 11 on the LEDs - one more than the previous model

• Configurable display programs and speeds with rear-mounted variable resistors
• Flashing your warnings in style

• Comes in pieces - enough to build 2 indicators!

This is an INTERMEDIATE KIT. It must be assembled in a specific order, and weird techniques are used for the LEDs.

Do NOT purchase unless you are familiar with, or are ready to learn how to soldering 0603 SMD components in tight spaces.

Do NOT purchase unless you have good iron pressure control or are willing to learn.

Kit includes:

• 2x AOA DISAGREE PCBs
• 2x WP CHIP digital logic
• 3x capacitors (1x per board)
  
• 7x resistors (3x per board)
  
• 4x dual male pin headers
  
• At least 25x LEDs (extras in case you melt some)
• 2x retention lanyards (required by GAT standard)
  

Please, maximum three kits per order unless prior arrangements have been made.
May include extra parts.
