Let's explore the fascinating world of Cordwood Puzzles and compare two intriguing kits: the Cordwood Puzzle One and the Cordwood Puzzle Too. Both offer unique experiences for enthusiasts and creators. Let's dive in:


1. Overview:

   - The Cordwood Puzzle One from Boldport is a tribute to the 1960s PCB assembly technique known as "cordwood."

   - In the 1950s and 1960s, engineers used cordwood assembly, sandwiching components between two circuit boards to save space.

   - While this construction method became less common due to advancements in component sizes and surface mount technology, it remains a lovely piece of history.


2. Features:

   - Old and New: The Cordwood Puzzle One combines both old-school cordwood assembly and modern design.

   - Puzzle Challenge: Assemble the circuit correctly using the provided components.

   - LED Display: Once completed, all LEDs light up when power is applied.

   - Individual Control: When connected to a controller board, each LED can be individually controlled.


3. Build Experience:

   - Requires through-hole soldering skills.

   - Unfortunately, comprehensive assembly guides were mysteriously missing from the kits.


4. Project #3 of the Boldport Club:

   - Cordwood Puzzle One was part of the Boldport Club series.


Cordwood Puzzle Too


1. Overview:

   - The Cordwood Puzzle Too is the second in the series of Boldport's Cordwood Puzzles.

   - It continues the tradition of cordwood assembly, paying homage to vintage PCB techniques.


2. Features:

   - Front Panel: The kit includes a front panel with switches and lights, reminiscent of vintage computing.

   - Z80-Based Computer: The Cordwood Puzzle Too is an 8-bit Z80-based computer with expandable card slots for add-ons.


3. Build Experience:

   - Basic soldering skills are required.

   - Assemble the components to create a functional replica of the original PDP-11/70 front panel.


4. Historical Significance:

   - The PDP-11 series played a crucial role in early computing.

   - Building this replica allows you to appreciate the hardware and interface design of that era.


Conclusion


Both kits offer exciting opportunities for learning, creativity, and nostalgia. Whether you're drawn to digital synthesis or vintage computing, these DIY kits provide hands-on experiences that bridg

e the past and present. Happy building! 🎛️🔧
