Version 3.0 is done and ready to be put up on instructables. I have not been able to finish the instructions as I have just started school back up but they should be coming, hoping for spare time. I do, however, wish to put up the code for the attiny85 PCM and have attached it to this project step.These instructions are not the most user friendly, a more user friendly set will included with the final SS instructions
It requires the Arduino-Tiny library, included in the zip file, and more specifically the optibook attiny85 board profile.
To make the PCM work: (taken from readme file)
* Locate the Arduino Sketch folder. This is the folder where the Arduino IDE
* Ensure the "hardware" folder exists under the Arduino Sketch folder. For
example, if the Arduino Sketch folder is...
Ensure this folder exists...
* Extract the contents of the archive into the "hardware" folder. For example,
if the Arduino Sketch folder is...
After extracting, the following files / folders should exist...
Open the code in the arduino software and upload to the Attiny using a programmer.
Update June 15th 2013: I am creating a v3.0 and v4.0, simple and complicated respectively. If anyone would like to suggest features for me to explore in these models I am willing to try to incorporate them. Theoretically one or both of these may become a kit version.
Update December 6, 2012
I am in the process of remaking the sonic with plumbing parts and attiny85's. The version I have developed uses 2 AAA batteries for power and should theoretically be louder. It also includes the TV-b-gone clone circuit. I am stuck in a coding problem to do with timers but hopefully soon I will have a new set of instructions. I am posting a process image above.
UPDATE! I have found a simple solution to a problem that I have been contacted about several times regarding the sound circuit. The trick is to remove all the wires but the two for power from the programmer before testing the device out.
I have two people who I am very close to who enjoy the show Dr. Who. For both of them I have made sonic screwdrivers to accompany their (mild) obsession. Both of the sonic screwdrivers make the proper sound and light up using a UV light however the more complicated one also turns TV's on and off, has an mp3 player embedded in it, uses a rechargeable battery, has a laser, has an FM transmitter and also shakes when activated. This instructable covers the construction of the simplified model to get a basic understanding however I include at the end a section on how I added features to the more complicated version as well as ideas for additional features I considered adding.
Attached to this step is a video of my first sonic screwdriver turning on a tv. The buzzing sound that is heard that should not be there is due to the vibration motor coming slightly loose. It is only noticeable within a few inches of the handle, past that the proper sound is heard loud and clear.
I do not like my props to feel cheap or breakable so both versions were made with metal handles and feature glass marbles as the light end. The amount of plastic exposed to the exterior of the sonic screwdriver was kept to a minimum so it appears as if it is a tool worthy of traveling the stars, opening doors, making cabinets and general tom foolery.
