A new instruction set was started for making a vibrating distance sensor with an inexpensive flashlight. Paper was laid down and instructions were written by hand in black and red ink. The purpose was to give instructions in a storyline fashion where the previous steps could be seen in the background but not be central to focus. Long scrap paper was used.
In retrospect the instructions should be carried out one step at a time with different parts each time so that a long panorama shot can be created and the entire instructions can be contained in a single image. This may even include code possibly linked with a QR code. Scattered tools in the background might be distracting but also lend some ambiance to the imperfectly framed shots. Animation could also be used to transition from one step to another.
Until a reliable method of switching power is made these instructions cannot be considered complete. This journal post is not meant as the final instruction set.
The instructions were not finished because the switch could not be integrated into the design. Ideally a small magnet on the moving part of the flashlight's switch would trigger a reed switch inline with the power supply but alignment and magnet strength were not easy to set up and the post holding the reed switch was flimsy. Holding a battery in place also proved to be troublesome so a different method will have to be devised.
