v3 was really really close to working. The PCB arrived and I assembled it: This picture was taken towards the end of the day. There are actually three steppers attached here. The one on the bottom left is different to the rest as I ran out of the threaded rod type stepper. The stepper on…
This idea of making a small robot has been knocking around my head for the past few years. Here is the original design (v1) from a few years ago: I made a mistake when programming the “fuses” on the AVR chip which meant it was effectively bricked. For some reason I never came back to…
This is the animatronic mask made by Keith Colton for the 2019 Dublin Maker Faire. This post will document the assembly and the current electronics being used. All images can be clicked on to view the full resolution image. Mechanical Assembly: In this photo you can see the animatronic mechanism. There are three servos in…
The last post looked at two time domain measurements of significant wave height, the highest 3rd calculation and the 4 times the standard deviation measurement. It turns out that the standard deviation measurement can also be made in the frequency domain. This is because the variance of a time domain signal is equal to…
