Production & Kits

Sorry for the delay in getting an update out to you. Here’s what’s happened in the last few months with the x0x-heart:

  • Pacemaker PCB re-designed for SMT (Solder Mount Technology) components and with holes in the board to allow you to tune the unit without having to remove the PCB stack with every tweak
  • Pacemaker PCB update prototyped and tested - is passed!
  • x0x-heart and Pacemaker PCBs manufactured by our friends at RW Technologies US LLC

This constitutes the bulk of the work, so there are just a few steps to go. We’re a little behind schedule, but are on track to have shipments out to you soon. More information to come in the next update.

What’s left to do:

  • Hand solder the TH (Through Hole) components on the pacemaker.
  • Final assembly.

Coming soon

Once production and shipping of the fully assembled units is complete, we’ll be offering kit options for sale. Thanks to everyone who emailed and Wiggled to let us know they wanted kits!

Talk to you all soon.
