Awesome 3m

Mat from UK channel Techmoan loves to dig up obscure old technology and examine it in depth. Here, he checks out an old 1970s tech from 3M and Ricoh which allowed audio to be recorded and played back from sheets of paper which were backed with a magnetic coating.

Apparel maker Heisel specializes in 3D printed and reflective clothing. One of their coolest products are these reflective socks. It has an integrated stripe of 3M’s Scotchlite retroreflective material. It’s available with a wide or a narrow reflective stripe.

3M spent 1,400 hours creating this sophisticated Rube Goldberg machine. The result is a wonderful maze driven by physics, chemistry and 25,000 Post-it Notes. The pendulums were both exciting and relaxing.

Another wonder product from 3M, Privacy Filters ensure that what’s on your laptop or monitor is only visible to the person directly in front of it, i.e. you. Available in a variety of sizes.

3M teamed up with Roku to create a portable home entertainment projector. It has a Roku Streaming Stick built-in and a battery good for about 2.5 hours. Its projection range is from 6″ to 120″.

Hate when some permanently defaces your whiteboard with a Sharpie? 3M’s whiteboard eraser takes care of both permanent marker and dry erase stains with just a bit of water.
