Note work on this is shelved until NeoDK can be manufactured.

The name "新電性" (Shindensei) means "New Electrical Sensuality."

Shindensai is an advanced electrostimulation machine development kit, inspired by the innovative NeoDK project.

Shindensai is a cutting-edge pulse-based electrostimulation device, offering a blend of simplicity and power. Its open-source design allows for both hardware and firmware customization, inviting creative modifications and enhancements.

Shindensai is an experimental and educational tool, designed for recreational use. It is provided "as-is" without any warranty. By using or modifying Shindensai, you agree to our License terms and acknowledge all associated risks and liabilities. This device should be treated as a novelty and not used for critical applications.

• Shindensai is to be used at your own risk.
• Avoid using for critical applications (medical, industrial, military, or illegal purposes).
• Ensure explicit and informed consent if used on others.
• Limit electrode placement to below the waist.
• Do not use triphase cables with this device.

Shindensai can produce high voltages and currents. Despite battery operation, its use involves inherent risks. Safety precautions are essential, but risks cannot be completely eliminated.

Shindensai is ideal for:

• Electronics hobbyists and professionals seeking an in-depth understanding of electrostimulation circuitry.
• Those looking for a robust, well-tested foundation for custom e-stim projects.
• Enthusiasts desiring high-intensity, remote-controlled e-stim experiences.
• Users seeking unique e-stim sensations beyond conventional power boxes.
• Innovators wanting a device that can store and play custom routines.

Embrace the forefront of electrostimulation technology with Shindensai.

Before diving into the enhancements, familiarize yourself with the original NeoDK design here.

• Expanded Connectivity: Integration of wireless operation capabilities, enabling control via smartphone or PC.
• Cost-Effective Customization: Tailor-made improvements that are budget-friendly.
• Modularity in Output Stage: Redesign of the output stage for better adaptability, making it more user-friendly for hobbyists and ensuring independence from the main controller.
• Operational Indicators: Inclusion of direct indicators on the device to display operational status.
• Planned Future Upgrades:
  • Integration of an internal customer-installable 18650 Li-Ion battery with USB-C charging support.
  • Development of a mobile application for enhanced control functionality.

• Component Selection: Preference for components primarily available through LCSC, multiple transformer alternatives
• PCB Design Simplicity: Commitment to maintaining a simple, two-layer PCB layout.
• Output Level Control: Incorporation of a dedicated high-speed DAC for precise output level management.
• Microcontroller Upgrade: Selection of a cost-effective RISC-V microcontroller that supports expanded connectivity options (USB, BLE).
• BLE Connectivity: Design of a PCB-mount inverted F-antenna specifically for BLE communication.
• Visual Feedback: Addition of LEDs to visually indicate channel activity and BLE connection status.
