Mr Carlson’s Lab had a defective Magnum Energy MS2012 Inverter Charger. When powered up the remote head unit indicates an Internal NTC fault. This fault indicates a temperature sensor fault issue. By looking through the diagnostic menu he could see that the system thought the FET temperature was at 151 degrees C when it was just powered on and should be reading room temperature. Carlson goes through the process of getting
Some wood, aluminum angle channel and roller bearings is what makes up majority of the camera slide that was designed by Making Stuff. There is a lot of precision that is needed to allow the unit to slide smoothly. Even though much of the design is cut by hand using a table saw and screwed together with a handful of drywall screws it works really well. A stepper motor
Saga is a Chinese smart phone manufacturer, their process of phone construction looks quite impressive. There is a ton of testing done all along the way. Saga makes phones for lots of companies. After seeing all of the work that goes into making these phones it is hard to believe the price point they can sell them for.

idogendel.com used an Arduino and some shift registers to create this nice looking Christmas Tree Ornament. The LEDs shine through the holes in the box and are diffused using the paper front. “I built this little Xmas-tree DIY Arduino project to demonstrate the use of the 595 Shift Register ICs (see link below) as output port expanders: 12 bi-color LEDs are handled using three 595’s and just three Arduino
ARMdevices.net takes a look at the Veger Power Bank Factory. Looks like a nice factory that can produce 10,000 battery banks per day.They have a nice assembly line but at each step I seemed to be thinking slow down. Speed is the name of the game here. I can see where those dodgy China solder joints come from by watching this video. Is the step at 5:07 the
If you are laying some floor tile and want to jazz up the look. Some inset LED strips might be just what you are looking for. Elektric-junkys.com has the items you need for this design. It is a lot of work but the end result is quite spectacular. Since the channels have the press in plastic strip maintenance is also easy since you can just pull out the plastic
