Grobenn25 built an interactive LED handrail system using an Arduino that monitors a large array of infrared sensors to detect what step the user is on. Based on the current detection pattern the stairs will light the LEDs under the handrail appropriately. During the production he looked at many different types of systems and settled on this overkill system. The sensors are changing their detection parameters constantly so that
Steve Marriott wanted to have some automated outdoor lights. They will be controlled by an Arduino that will monitor some PIR sensors to see what is going on and turn lights on based on activity. A few tictac boxes were used to mount the outdoor electronics in. The project changed over time based on community help. The end result is a a completely automated lighting system that looks
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.
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.
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
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
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
