RC Tank that Prints without Support, Assembles without Hardware and Wires without Soldering

https://www.youtube.com/watch?v=XKXZaKyjVCw

  • Prints without support!
  • Assembles without hardware!
  • Wires without soldering!

This tank does not require a single bolt or nut. You just print the parts, put them together, connect the motors and electronics, and it’s ready for battle. It shows excellent off-road capabilities, and turns on a dime. Each of this tank’s two tracks is printed in a single piece, thus eliminating the need for assembly hardware.

The machine shown in the video below is powered with a Picaxe 20M2 microcontroller installed on a 300-hole mini-breadboard. There is also an H-bridge motor driver, an IR sensor, a couple of resistors and capacitors, and a whole bunch of jump cables. The entire set of electronic components used here can be bought on eBay for just a few dollars. The tank is operated with a regular Sony TV remote control.

Firefox Not Playing with Norton, YouTube, Yahoo, etc.

Does anyone know about this, and what to do?

I get these Firefox massages about other sites’ security certificates not being correct, and I see examples from other CR4 members. I can understand Yahoo being on the outs because of recent security breaches, but Norton/Symantec?

Are other browsers doi

Pete French Round Barn

Located near Diamond, Oregon, the barn was constructed sometime in the late 1870s or early 1880s. There were originally two—or possibly three—in the vicinity, but this is the only round barn remaining. The video also shows the unique landscape of the high plateau in eastern Oregon.
