  1. Measuring Video Transmitter (vTx) RF power and checking antenna performance are two things a lot of FPV'ers would like to do. ImmersionRC sells a nice RF Power Meter but its $150 USD price tag is a problem for most hobby budgets. But I have low cost solution for you. How about a DiY digital RF Power meter for less than $30 USD? Its 433MHz to 5.8GHz frequency range means it can handle all your FPV devices. Max input level is 0dBm, but much higher RF power is acceptable with an external attenuator (budget $20). And it can measure antenna VSWR if you add a RF Directional Coupler (budget $65
  2. I've decided to create a talking skull for Halloween. Anyone that wants to do this will find that the internet is full of DiY instructions on building one. But I prefer to roll my own designs, so I started fresh. After all, the adventure in creating such things is all part of the fun. First I needed a skull (with or without a body) that had a hinged jaw. These are easy to find this time of year (Halloween season). The local big box hardware store was advertising a five foot posable skeleton for only $30US that would have been nice to use. But they were out of stock, so instead I purchased
