Plotting AI-generated art onto paper
Reading Time: 2 minutesAI-generated art is all the rage right now, thanks to widespread sharing on social media. The appeal is obvious: anyone can utilize an online service to create a unique (and often hilarious) piece of art based on a simple prompt. To display that art, one can utilize a high-quality printer or a…

A CNC pen plotter with very unusual kinematics
Reading Time: 2 minutesThe vast majority of automated, CNC-controlled machine tools utilize a kinematic motion system that is (not coincidentally) the easiest for people to wrap their heads around. This is your standard Cartesian layout, in which the tool head rides on linear rails along two or three axes. But there are many other kinematic…

3D-printed continuous rotation servo motor is super smooth
Reading Time: 2 minutesThere are three types of motors that makers typically consider: stepper motors, servo motors, and DC motors (either brushed or brushless). Stepper motors are great when you need high precision and torque, but tend to have jerky movement. DC motors work well for high speed movement that doesn’t need any rotational accuracy.…

An awesome new open source long-range RC transmitter
Reading Time: 2 minutesDSM (digital spectrum modulation) is a relatively new radio control technology that is ideal for long-range applications. It uses two methods, FHSS (frequency hopping spread spectrum) and DSSS (direct sequence spread spectrum), to transmit data, with the latter being especially resilient to interference and therefore suitable for transmission over long distances. If…
