A few years ago I made animatronic singing pumpkins using an Arduino Uno, a Wave shield, a 16-channel servo/pwm controller, and some DC-DC power converters, all from Adafruit. I designed a single PCB that unified all of that and included a 15W amplifier. Today I completed assembling that board and began its commissioning. I used solder paste and a mylar stencil cut on our laser. Its the first time I have ever soldered a TSSOP package with no shorts.
Anyway, I managed to forget to bring a microSD card, but the program loaded into the AVR OK and is running. All the various power supplies are outputting the correct voltage. 6 volts for the servos, 5 volts for the AVR, and 3.3V for the microSD card and buffer chip. The amplifer gets the raw 12 volts. So, I’m hopeful that over the next week I’ll be able to bring the board completely online.
Dear Royce,
I hope all is well with you. My name is Lauren Williams and my classmates and I are developing a tablet magazine called Badger here at Syracuse University. The magazine is geared toward men with beards and their other interests.
I found your blog post on Milwaukee Makerspace website about the Singing Pumpkin Controller. I thought it was so cool and I was wondering if I could work with you on a story, as well as a how to video on how someone could make one of their own? Where did you get your materials?
I understand that the information is available to members of Milwaukee Makerspace, but I hope that we are able to work together on this. Thank you so much for your time and any help you can provide my editorial team and me. I look forward to hearing from you soon.
Sincerely,
—
