Macbook Backlight Repair
Louis Rossmann shows how he walks through a Macbook Backlight Repair. As usual the scale of the repair is tiny and work under the microscope is needed. Some tiny jumpers and a steady soldering hand come to the rescue.
Power Supply Decoupling and Filtering
w2aew demonstrates the use of decoupling and filter cap usage. We have all seen large electrolytic caps and tons of small capacitors near chips on most circuit boards. Why are they used and without them what does the circuit look like. The live demonstration on the scope with the test PCB does a great job in demonstrating the difference with capacitor placement and operating without capacitors.
Pizza Box Robot That Shines a Laser in Your Eye
Michael Reeves is a software developer at Infibit that has made a face tracking robot that is housed in a pizza box, it tries its best to find your eyes and shine a laser in them. The software that runs on a PC was written in C# and uses Emgu CV which is the .NET version of Open CV for the facial recognition portion. A web cam is
DIY SOLAR TESLA POWERWALL
Instead of purchasing a Tesla Power Wall jehugarcia shows us how a DIY version can be put together. The EV West facility has a large flat roof which makes laying the panels nice and easy. The roof is crazy high so getting them up on the roof looks like it was not that simple. The video at the top shows a bit of the solar panel installation and the lower video
Mini Spot House Robot
When you think of a robot in your house you probably think of a Roomba. I want to see a milti function robot that is capable of doing more. Automation is great when it can do complex tasks unaided that help us out. Just imagine coming home to the dishes done, the floor cleaned and a cold beverage presented to you when you sit in the couch. This sounds
Edge Lit 481 Digital Voltmeter Display
This Edge Lit 481 Digital Voltmeter Display totally makes me want to build a clock with this mechanism. Can you imagine talking a measurement with this meter that oscillates, it would make a ton of noise. I can see this being great help if you were siting on a stable reading and waiting for something to avalanche. Via: Hackaday “These early NLS digital meters used a resistor dividing network and
DIY Vacuum Chamber
Chris Notap shows us how to make a DIY Vacuum Chamber for under $30. The heart of the vacuum chamber is a recycled compressor pump from a donor fridge. It is simple to construct with a piece of wood as the chamber base and something as simple as a mason jar acting as your chamber body. A few pop bottles are used as a simple free valve. You can see some
