I finished the last installment of “Building IT” with “what’s next?” What was next was to wire the circuit boards and test their functions. The picture here doesn’t look very different from yesterday but that’s the nature of projects. In the beginning, change is obvious. First there is nothing then there is something. In the middle of the project very little seems to change. It’s like the project absorbs work.
In spite of that apparent effect, I accomplished a lot today. Notice that the two boards are now joined and there are wires connecting all the components. The small board on the workbench is simply for testing. Lights on the board indicate what is happening. The lights will be replaced with other components such as linear actuators and a motion sensor. One of the wires will activate a store purchased jumping spider. I’m hoping that that will be easy but I’m not holding my breath.
Everything works and the next step is to place the circuitry in a weather proof container and mount it to the prop. Then the prop components can be connected to the terminal strip on the outside of the container. With the exception of one last remaining hard
thing to do, the rest of the build should be easy. The hard thing is mating the homemade portion of the prop with the store bought jumping spider. I expect challenges. The linear actuator motors sometimes interfere with the Chinese circuitry in Halloween decorations. I may have to apply power to the spider only when I want it to be active. I’m hoping that that won’t be necessary but I’m prepared to if needed.
- Mount the circuit boards
- Connect the actuators, lights, motion sensor, and spider
- Fine adjust and play
