Worcester Rules.

I've been in Worcester for almost a week now, and it's been intense! Basement shows, punk events, and a whole lot of good times! I've constructed a few electronics projects as well down at the FYC, including a regulated 8 V DC power supply, and a pocket headphone amplifier. Here's some pictures!

Fuck Yeah Center is pretty awesome. It's coming along, with tons of events for the Summer of Worcester, great attitudes, and great junk! As for my headphone amp, it sounds splendid! I've been working with the power supply for the design, but I was pleasantly surprised when I tried it off of battery power and it sounded even better! I got the whole thing to fit into this tiny little enclosure, with some bending of the capacitors and some tight squeezing, but I love the form factor! I'll update this entry or maybe another soon enough with some details, schematics, and labeling of the pictures. For now, I'm just gonna get back to vacationing as hard as I can!

Angles!

The amp, stuffed tightly into my little enclosure. It runs off of a 9V battery or a DC power supply! The switch on the left controls which power supply to use, when switched to the DC input, if no supply is present, it is off, and disconnects the battery. The amplifier is custom designed for the sound I wanted, and based off a similar design that I built and didn't like the sound of. The amp's heart is the LM386 audio amplifier 8 pin DIP IC chip, and is quite nice! The amp take in a 1/4" mono phone input, and outputs in mono mix to stereo headphones via a 1/8" stereo jack. When the circuit is on, a green LED runs to let the user know that they're turning battery power into rock music. The 100K Ohm Log tapered stereo potentiometer will be cut and knobbed in the short term future. I forget how much all the components cost, but I am considering making a run of 10-20 of these in the short term based on the response of my friends at the sound they created. Custom electronic music effects for guitar, bass, and vocals are next up on my agenda!
