Stepper Motor - Series Connected Splitter Board
2 layer board of 0.53x0.72 inches (13.51x18.16 mm) - $1.90
Got the idea from HERE
Found a series stepper motor splitter design HERE and you see the result. He is selling them but shipping prices from NZ make it cost prohibitive especially for DIY'ers. Discussion HERE Further Discussions
Per the above site, this board allows you to connect the steppers in SERIES providing the full driver current and ensuring maximum torque at nominally low z-axis speeds.
I made sure the traces were thick and on both sides to handle high current

Tested and working !
A retro watch, based around the HP QDSP-6064 Bubble display, used in 70s HP calculators like the HP-35. The display is controlled by an Atmel ATMega328P-AU MCU with Arduino code, and the time is kept by a Maxim DS3231 Real-Time Clock module, that stays connected to the LiPo battery at all times, keeping time even when the microcontroller and display are not powered.
The code and design files for this watch are fully open-source, and available on GitHub.
(DISCLAIMER: I am in no way affiliated with Atmel. I just put the Atmel logo on the PCB to show the circuit uses an Atmel chip, which I really like !)
