When our new computer overlord arrives it’ll likely give orders using an electromagnetic speaker (or more likely, by texting instead of talking). But for a merely artificial human being, shouldn’t we use an artificial mouth with vocal cords
chords, nasal cavity, tongue, teeth and lips? Work on such a thing is scarce these days, but [Martin Riches] developed a delightful one called MotorMouth between 1996 and 1999.
It’s delightful for its use of a Z80 processor and assembly language, things many of us remember fondly, as well as its transparent side panel, allowing us to see the workings in action. As you’ll see and hear in the video below, it works quite well given the extreme difficulty of the task.

This 3d printing delta robot really seems to solve a lot of the hurdles faced by previous offerings. With other delta printers we’ve looked at the motor control of the three arms is usually a it complicated. On this build the motors can just be seen in this image at each corner under the build platform. Each motor has a belt that loops from the bottom to the top for the machine, driving an arm along two precision rods.
It’s also interesting to note that the printer head doesn’t have a motor mounted on it for feeding the filament. Instead, the motor is mounted remotely. You can see it above the soda can in this image. It feeds the filament through a hollow tube spanning the gap between the extruder and the motor. This acts as a Bowden cable. With less mass to move this may make it easier to control the location of the print head.
After the break you can catch a clip of the team showing off the speed and dexterity of the delta bot, followed by a printing demo.
