Electric Massager Update

My creation was finished last week. It is still fully functional and working. I am now working on my final report for my creation. It will serve as a how to guide for others that desire to make a creation just like mine. Soon, the how to guide will be released to the internet for eternity. Anyone will be able to use it for the rest of time. I advise everyone to make their own electric massager. Best of luck in your building of your own creation.

Electronic Massager Part II (Speir-O-Lator)

This week, the electronic massager has been completed. It was soldered onto a PCB board. There were no difficulties during this process.  After this, the project was fully functional, but it was not yet complete. The board, along with the battery supply and the transformer were mounted inside of a scavenged computer power supply box. Two wires from the transformer ran out of the box and into the an Altoid container. Inside of the container, the wires were soldered onto two pennies. The pennies were hot glued so that a portion were outside of the container. This container serves as the probe to deliver the electricity to a person. At this point, the device was completed and named the Speir-O-Lator.

Electronic Massager

I began work upon this project during the beginning of this week. I assembled it upon the breadboard and it worked the first time, but without enough voltage making it to my transformer.  I read the voltage readings with the oscilloscope. This confirmed that it was changing the voltage to a AC signal but it was too low. I was using a 555 timer and it was sending pulses every few milliseconds. However, the timing and amount of voltage was not correct. I changed the resistance going from power to pin seven and from pin seven to pin six and two. Changing these affected the amount of voltage coming out of my circuit. After several trials, I went with 33k from power to seven and 20k from seven to six and two. This was giving me about 30 volts AC out of the transformer from 4.5 volts of DC going into the circuit. This was then tested on Noah Slater to see if it hurt of not. I slowly turned up the 5k potentiometer increasing the voltage. It did not hurt him, but gave him a tingling sensation. I then, along with several other people, tried it out for myself. I am now beginning to solder and will finish sometime next week.
