Enjoyed talking with @prcutler on this ep! Learn how I planned to get the drop on Happy Meal toys, the Isle of Misfit Boards, rising to the top of the charts with a four chord song, what would happen if Freud played Shadowrun, and the Macropad Hotkeys II.

However, you can go a lot further, too. [CNCDan] demonstrates this well <a href="https://github.com/dmcke5/Hapticpad" target="_blank">with his sleek macropad build</a>, which throws haptic feedback into the mix.</p>
<p>The build features six programmable macro buttons, which are situated either on side of a 128×64 OLED display. This setup allows the OLED screen to show icons that explain the functionality of each button. There’s also a nice large rotary knob, surrounded by 20 addressable WS2811 LEDs for visual feedback. Underneath the knob lives an an encoder, as well as a brushless motor typically used in gimbal builds, which is driven by a TMC6300 motor driver board. Everything is laced up to a Waveshare RP2040 Plus devboard which runs the show. It’s responsible for controlling the motors, reading the knob and switches, and speaking USB to the PC that it’s plugged into.</p>
<p>It’s a compact device that nonetheless should prove to be a good productivity booster on the bench. We’ve featured [CNCDan’s] work before, too, <a href="https://hackaday.com/2](https://files.mastodon.social/cache/media_attachments/files/116/021/341/685/784/402/small/55406458845b5c59.png)
