New Product Roundup – February 25th to March 3rd

It must be Saturday as we are back for another New Product Roundup! This week we have just a couple new products to look at – a brand new add on for the Raspberry Pi Zero to turn it into a USB dongle and a new type of vibration motor. Let’s go have a closer look at each!

Miniature Vibration Motor

This tiny pager motor / vibration motor is a simple DC motor with an offset weight on the output shaft. This offset weight creates a vibration which can be used for haptic feedback in a project or even tiny brushbots! Two wires are used to control/power the motor. Simply provide power from a battery (red is positive, blue is negative) and it will buzz away.

Pi Zero USB Stem

The Pi Zero USB Stem is a PCB kit that turns a Raspberry Pi Zero into a USB dongle. Once the Stem is installed, your Raspberry Pi can be plugged directly into a computer or USB hub without any additional cables or power supplies. The Raspberry Pi then acts as a USB device using its own Linux kernel gadget drivers to get started. The Zero Stem is designed to be soldered directly to the USB SMD test pads on the bottom of the Raspberry Pi Zero, needing no wires or pogo pins at all, just solder and a soldering iron! Attaching the stem to your Pi also allows you to create a portable VNC server, or even cluster several Raspberry Pi Zeros with just a USB hub.
