Hi Folks
I though I'd put up some PCB that I made for a couple of projects. As I have mentioned before I do animatronics as a hobby so the projects are for this
The first board is for an animatronic tail. It uses an 08M. I recently found some FLEX sensors that will measure bending. I have incorprated these into elastic sleeves that slide over the user's knees. This way I can measure how much the user has bent their knees and thus work out how fast they are walking. I can then control the tail to 'wag' at that rate giving a natural gait.
The 08M uses 2 ADC to work that out and by subtracting the values I know which direction to swing the tail
The 08M also controls two heavy duty servo's giving lift/drop and left/right capability. Like the previous circut I am using an interrupt/serial command structure so I cn have additiona; emotions. Thes are Happy (tail lift), Sad (tail drop between legs), Slow wag, Fast wag, and Auto (using Flex sensors). Plus any other variants I wish to program.
The second is for a 18X eye light controller. My main suit has sunglasses lenses for eyes, and I use a LED behind the glass to simulate a pupil. This used to flash at a regular rate using a 555 timer. This version can controll 3 LED's for each eye (using fibre optic to get the light to the lens) plus using PWM to vary the brignhess. The two chips are a 18X and a ULN2003.
The 18X will be controlled using a serial connection with a HIGH pulse to cause an interupt followed by the command.
Hope you find this interestng
