Magpie Modular - Plancks

An 8hp reinvention of the Mutable Instruments - Frames module (reducing from the original 18hp). Developed in collaboration with Neutron Sound this is the smallest reimagining of Frames we could come up with and features some new aesthetic twists we haven't tried previously. The acrylic window insert diffuses the LED light and looks quite impressive when powered up and put into action.

Acrylic Insert included with the purchase of the panel.

It is named after the Planck Constant which at the time of writing is the smallest theoretical quantization of space... the smallest frame if you will. (I know this could be argued with the current reworkings of Einsteins field equations and the e8 model... but does it really matter?) anyways.

This is Open Source Project

Want to contribute? This project could benefit from your input. Contact us if you are interested.

We are a small 2 person shop and unfortunately do not have time to be able to offer any build support or answer all your questions about troubleshooting your DIY builds, but do our best to reply in a timely manner and point you in the right direction. For the most part you can safely consider this identical to a regular Frames.

If you really want one of these and don’t have the DIY chops to build your own we recommend you join our FACEBOOK GROUP and find  a builder who is making these to order. There is a great community of savvy builders sharing information here from all over the globe. Also, join the conversation with Magpie on Muffwiggler.

Please be advised: This board is 0603 SMT components and thus not suitable for beginners. If you would like a good introduction to the sDIY world we recommend a simpler through-hole kit such as the Mikrophonie and working up in complexity from there.

Before purchasing be ensure you are comfortable with setting up the development environment needed to compile the firmware and flash these units and understand the basic flow of working on microprocessor based builds. That said: The point of providing these boards is that learning to work SMT is not an insurmountable task and with proper research, practice and steady hands you might actually prefer it. (or not)

If you are interested in a simple SMT build in which to start we recommend something analog with a small part count, such as a Links or Shades. Working up from there Branches is a nice easy introduction into microprocessors and then I find all the others about the same.
