We are excited to announce the addition of several new Creme DeMentia Bottle-Cap products now available in the shop. First, we have our new EconoMIC Bottle-Cap Contact Microphones (see below); they are made from reused plastic soda caps and are significantly easier to build than our original Creme DeMentia Bottle-Cap Contact Mics.

The New EconoMIC

Using this design, we are now able to produce one of these from start to finish in about an hour and a half; this enables us to teach the construction of these microphones in a workshop format and we are doing just that!  CMKT 4 have already taught several successful workshops on building microphones this way at the hacker spaces Omnicrop Detroit, LVL-1 Louisville, and Hive13 Cincinnati.

At our workshops everyone learns to properly wire up a piezo-electric disc to a 1/4” jack. They will also work with hot glue, zip ties, shielded cable, tool-handle dip and pre-drilled bottle-caps to make a sturdy and fully functioning EconoMIC Bottle-Cap Contact Microphone. These microphones pick up physical vibrations and change the vibrations into an electrical audio signal. Students are encouraged to bring instruments and found objects to listen to through the microphones.

There is a dry-time involved in the materials we use and during that time we play a CMKT 4 rock set for the attendees. For performances, we require the use of a PA.

Creme DeMentia Bending Buddies, never circuit-bend alone again!

We are also pleased to announce our new Bending Buddies.  These handy little patchable body contacts allow you to experiment more easily with your body’s own resistance. They are intended for use in circuit bending: Hold the body of the Bending Buddy in one hand and operate the body contacts. Then, with one clip-lead attached to one spot the circuit board, probe with the other clip lead. Soon enough, you’ll be able to hear controllable changes as you investigate battery-operated circuits with your body’s resistance. You can then further test out and wire up your discoveries. Also now available in the shop, along with our Original Bottle-Cap Contact Microphones.
