 There are a number of great older bench meters out there that would be perfect when upgrading from a hand held meter when working on the bench. The HP 3468A meter can be had for under $200 in good working condition and often around $100 for a unit that powers on but no operation confirmed. Modemhead purchased one that was DOA, have a look at the pictures he
Ok, this is a very interesting motor that RimstarOrg built with some scrap wood, two bearings, a bolt and some nuts. It is connected to a low voltage high current power source and can magically spin (or can it???). Watch the video to 3:20 but no further. Is this a real motor? Is there some careful camera tricks at work here? If it is real how does it work?
Some new cars such as the Audi A8 pack some high tech electronics to enhance safety. Mike’s Electric Stuff has a look inside the Audi Night Vision System. “Located in the Driver’s Information System, between the speedometer and rev counter a camera’s eye view of the road ahead is displayed to the driver. The system will highlight people using their heat source. Typically a person standing by the side
  If you still have a few floppy drives left over after making your Floppy Drive CNC machine have a look at making some music by making a Floppy Disk Jukebox!  “The overall setup is completly modular. Each floppy is connected to its own floppy driver (rrfdc), which in turn speaks I²C with the main board (rrcmd). On power-on the main board auto-discovers the connected floppies and adjusts the
 Forrest Bourke, Saarth Mehrotra, Michael Searing and Elliott Wyse from Olin College of Engineering built an interesting project called The Confectionary Cannon, it is a Face Tracking Marshmallow Shooting Gun! It uses air pressure which is released by a sprinkler valve to launch marshmallows to their victim using face tracking to get it done. Via: OhGizmo and Hack a Day  “After sketching out a few initial designs, we designed
If you have something in the real world that you would like to monitor this Arduino Data Visualization will help you to do just that. “Hardware: Arduino (We’re using the UNOr3) Ethernet Shield DHT22 Temperature + Humidity Sensor Hookup wires Angled pin headers (unless you use female-male hookup wires, then you won’t need these) 9v Wall Adapter Ethernet Cable Software: Latest Arduino software (1.0.5) Plotly Arduino Library Adafruit DHT
 If you are in the market for a Logic Analyzer the DSLogic might fit the bill. At time of writing it is fully funded and you can get the early backer board for $49 (there are still 13 left). The next step up is $40 more and gets you the test clips and a USB cable, if you don’t mind making some test leads yourself you can save
