This video shows how I made a circuit that flashes very bright LEDs to help in visually tracking a drone. It utilizes a PIC microcontroller. Details and more information are available at www.trainelectronics.com/Drone/Beacon/

This video describes a method of using a laser cutter to create prototype circuit boards from Gerber files. The laser cuts acrylic plastic that can be used to mount components and wire point-to-point. This method works well with small single sided boards and can be used to test component placement before ordering circuit boards. The boards made with the laser cutter DO NOT have conductive trace...

This project uses an Alexa controlled relay and a simple servo tester to activate a wooden "finger" that is used to activate a laser cutter. It requires no programming and only minimal soldering. For more information please visit my web page at: www.trainelectronics.com/Servo-Alexa/ or email dave@davebodnar.com

This video shows how you can make a wireless temperature sensor system using a temperature sensor, two Arduinos and two radio modules. For more information see www.trainelectronics.com/Pond-wireless-temperature/index.htm

Small, inexpensive microwave sensors are available that do a super job of detecting movement of people or objects by bouncing radio waves off of them. This video show how you can use such a sensor to trigger a microcontroller or relay. More information is on my web page here: www.trainelectronics.com/MicrowaveRADARSensor/index.htm

A simpler motor controller is added to the Incline project that is available here: ruclips.net/video/MXcwi5Mpo6c/видео.html More details on the controller are here: www.trainelectronics.com/Incline/InclineController/index.htm

The PowerPoint slides are here: www.trainelectronics.com/presentations.htm Join Dave Bodnar for his 14th ECLSTS seminar and explore how easy it can be to use microcontrollers and other simple electronic devices to enhance your railroad. We’ll look at circuits you can build with the Arduino family of microcontrollers, how a laser cutter and/or a 3D printer can be an excellent and exciting additi...

This video and the accompanying web page show how an HO model of the Duquesne Incline was made using CorelDraw and a laser cutter. For more information on the project visit www.trainelectronics.com/Incline/

This video is a 10 minute tour of the South Hills Model Railroad Club (SHMRRC) modular train layout that was set up at the Scott Township Community Building. The layout was open to the public on March 1 and 2, 2019 and was visited by hundreds of railroad enthusiasts. Thanks to the community and library for providing this opportunity to show our layout. For more information about the club visit ...

In my last video we explored what was needed to get a fidget spinner based brushless motor spinning at over 5000 rpm. This video shows how you can measure the speed of the fidget spinner and includes an Arduino based tachometer. For more information visit: trainelectronics.com/FidgetSpinner/tachometer.htm

A number of folks who viewed my earlier Fidget Spinner videos (see: ruclips.net/video/FvagOj-yaK8/видео.html and ruclips.net/video/jfLUc7iLbp0/видео.html ) wanted to see how fast I could get it to rotate. In this video I show the things that I needed to do to get my fidget spinner brushless motor turning at a rate of 5000 revolutions per minute ! ! ! As usual more information, more photos and l...

I just got a new vanity plate for my car and think it is somewhat unique (at least in Pennsylvania). See if you can figure out why I chose this plate and the significance it has for several of my hobbles / interests. Please leave your thoughts / comments below. thanks! dave

Last year I posted a video showing how you could simulate a thunder storm with synchronized thunder and lightning. SEE: ruclips.net/video/7WtKiwUSyco/видео.html This revision of that program allows you to have the sound of thunder delay for some time after the lightning is seen. This more closely simulates what happens in real life when a lightning strike might be a mile or more away. More info...

This video shows how a simple animation was made using motors and limit switches. The animation automatically rotates two trolley conductors when the trolley's direction changes.
