What a great day. I got a bootloader burned into the Meistersinger Atmega2560. This one has a watchdog timer issue and needed a bootloader with the correction. I used an Arduino Uno to burn the bootloader using a sketch I found online. Got it all back together and added the watchdog code so if the thing crashes it will recover. It crashed twice in the past 6 months. After lunch I went outside and added lime to the pansies and questionable fertilizer. The fertilizer was very wet and possibly not effective because the good stuff may have washed out. My next act was to diagnose the hot tub. Bought a brass plug, 1/8 inch, from Lowes. Replaced the pressure switch with the plug and worked on the switch. Seemed to have gotten it going again. Hooked it up and the water is heating at 1.5 degrees per hour. Woo Hoo! The Super Bowl is on tonight. Libbie is watching it but I'm not. Went downstairs for some pizza which was our dinner - another winner by Libbie!!! Came back upstairs to read "Strength in What Remains" by Tracy Kidder.
