Dave takes you on a highlights tour through the first Sydney Mini Maker Faire at the Powerhouse Museum. This is the overview video, more will follow with behind the scenes stuff and extended interviews. Forum: http://www.eevblog.com/forum/blog/eevblog-551-sydney-mini-maker-faire/

Dave checks out the Manfrotto 396B 3-section double articulated arm to see if it’s suitable for his bench video camera work. Also, the Manfrotto 035 super clamp and the 237HD heavy duty flex arm.

Dave tests the myth that plugging a PCB VIA with solder does nothing (or not much) to improve the current handling capability. Is manual wire feed-through any better? Does the industry rule of thumb of 0.5A per VIA have any basis? What is the typical plated VIA/hole thickness? http://saturnpcb.com/pcb_toolkit.htm Previous videos on PCB solder coating: http://www.youtube.com/watch?v=L9q5vwCESEQ http://www.youtube.com/watch?v=cScVqD6eIaU Does a PCB VIA halve in resistance like a PCB trace does when coated with solder?
