Projects I would like to do, but cannot seem to get around to: Programmable Thermostat control for my home heat pump. Programable Thermostat control to auto-start an automobile to assure tolerable conditions for animals (dogs) on board. Police cars just leave them run, but there have been occaisions where the vehical has been left in an unsafe situation. Automatic mixture control for model aircraft engines. Many otherwise good engines seem to suffer from a mid-range rich condition. Carburator design seems more art than science. Fully programmable RC transmitter. The current models are great but you have to bend your use to their characteristics. The RF section is a separate issue, the initial effort should be in the Ham bands. Current encoding schemes or a new system altogether to be considered.
