In the interest of making life complicated...
Suuuuure, that's just what I need. Wasn't expecting tne response to this project to be quite so overwhelming, but having put our a** out there to do it, we will persevere.
Can think of lots of great options, and PWM to reduce power usage is a great idea. Has a couple issues though.
1. Our background is mechanical, not EE so every iteration of circuit design is like giving birth, painful and slow.
2. "Fat Finger Syndrome" One of the primary goals is to be able to offer a DIY Kit at very low cost to reasonably competent individuals in order to allow them to assemble a FrankenBebi onboard with a minimum of hassle. The PCB we have designed is 1.4" in diameter and currently (with the integrated day/night switch) looks like this
To construct the FrankenBebi without the "day/night" switch you insert a jumper wire between J1 and J2. Regardless, we are running out of room for a practical hand placed, hand soldered board, for us at the Project, or for the DIY Kit folks. Maybe in the future we can pursue your suggestions as they have merit, but at this point our goal is to get a good, simple version out for test and use.
It seems a pity for Bebi to be lost and I wonder if the owner has any plans to continue his work, or patents on his designs.
I see that we have not mentioned it in this forum, but while we have not discussed this with Michael and Kendra (Bebe-Electronics founders) directly, we received word via a third party on another forum that they are aware of the project and have no problems with our moving forward
Michael and Kendra are friends so I wanted to check with them about this. I just received an email back giving their blessing to your project.
They were not only good enough to give us their "blessing", they actually made some suggestions as to design issues we may face. Great stuff, and much appreciated. The Owl was a great design and product, and we only hope to be able to improve on their design, reliability and service.
Thanks to all for your input, interest, and ideas.
