Ring Engineering has released a second generation of their RailPro product line: Locomotive Module (LM), Handheld Controller (HC) and Power Supply (PWR). I have been watching this product line for a few years now, and this comes as exciting news.
At approximately 5:10 pm, Wednesday, July 17th, 2013, Samanatha Loman, eldest daughter of Sandra and David Loman, was involved in major vehicular accident. The car involved in the accident was severely damaged when it struck a house at high speed. Ms Loman walked away from the scene uninjured.
In reality, she was carrying her newly completed 1:24 red Ferrari over to her ‘model road’ to stage a scene when she dropped it. It literally shattered into its original parts. She was really upset, but I pointed out that none of the pieces themselves had broken, but rather, the pieces had simply come apart. Superglue, it seems, provides quick bonding but lacks the sheer strength that model cement provides. Good to know.
Making the best of the situation, and trying to get her to smile again, we staged a scene anyways. Always look on the bright side of life!
Epilog: The model has been rebuilt with less superglue and more cement. Order is restored to the universe.
I got tired of continuously calculating resistor values for various low-voltage applications (Launchpad, USB power, Batteries, etc), so I put together a Quick Reference Chart. To use: If you want about 20mA through an LED, the LED has a listed Voltage Drop (Forward Bias) of 2.8V, and you have a 4.5V supply (3x AA Batteries), then your appropriate resistor value is 85 Ω
