Description

After almost 6 months of development and prototyping the ROTR has arrived. The 3 man team at polarity works have been working almost non stop to make this the last macro pad with knob you’ll ever need. Drop some switches into the minimalist anodized aluminium housing, connect the usb C connector and the ultra bright RGB lights blaze into life and you’re ready to go!

After 4 revisions the knob mechanism has been perfected, using a pair of Japanese NMB bearings to float a precision machined steel shaft underneath a beautifully anodized and tactile knob. Underneath the shaft sits a magnet and under that some air. The only contact between the knob and the shaft is through the bearings. Unlike our cheaper competitors this means there is no notchiness, no clicks and almost no resistance. You can spin this knob by blowing on it gently! If greater resistance is desired there is the provision to put magnets in the knob to allow for eddy current braking. This has previously been used on Japanese shinkansen and German ICE3 high speed trains. The resistance can be varied through 12 levels by varying the position of the magnets, and it doesn’t make a difference to the silky smooth nature of the mechanism.

The knob on the ROTR is swappable, its non-contact mechanism meaning you can just pull the magnetically attached knob off and snap on a new one. We custom machined a tapered precision interface, the design of which we will release to the community to allow for third party knobs. We will offer replacement knobs made out of aluminium, brass and copper so you can make your ROTR fit your chosen aesthetic

The ROTR is fully programmable, using QMK firmware you can set up a wonderful combination of layers and macros to your heart’s content. The profile is online on the QMK configurator so making tweaks trivial and allows for an endless amount of customisation, volume knob, scrolling through the timeline in editing software or a cad controller, the options are limitless. If you decide that even that is not enough we broke out 8 I/O pins, the programming header and the led data out pin, allowing for hacking and modification to truly make it your own, add extra buttons, a second encoder, RGB underglow. It’s all possible without tricky surface mount soldering.

Photos and renders may differ slightly from the real product.

Please be aware that Brass and Copper Knobs have a sandblasted texture finish, but are intentionally left uncoated, in order to allow the material to develop a patina over time.

You can preserve the condition of the brass / copper knob with varying degrees of patination by coating it with clear lacquer. Please see here for for some examples.
