Unlimited Freedom: Day 1

Two hours after getting home from work I’m already basking in the newfound carefreeness thanks to the successful completion of my thesis defense (and graduation requirements). Yesterday I went to skycract, early this morning I posted a schematic diagram of a basic circuit concept for a radio/microphone interface box with tone generating functions, and this afternoon I finished its assembly. It’s hacked together, I know, but it’s a PROTOTYPE and is for functional use only. What does it do? It’s complicated, and I described it in the previous entry. It’s basically just an exercise in microchip programming! Here are some photos…

Here’s that internal photo I promised I’d get posted yesterday…

Here’s the little setup with the main control unit and a DC to DC regulated power supply / serial microchip programmer I made.

Here’s the main control box. Notice the “2-way lighted switches” which I described in the previous entry (I posted the schematic). I found that proper grounding (floating pin prevention) was critical to their proper function. I’m still new to these chips, so I’m learning, but I’m making progress!

Getting a little artsy with my photographs now… this is the core of the device. It’s a picaxe 14m!

This is a ~? to 5v regulated power supply I built. The headphone adapter is for easy connection to the serial port. It has a power switch and a program/run switch (allowing use of pin 13, serial out) while still “connected” to the PC.

I wanted to toss this picture out there. I’ve slightly improved the connection between my radio’s coax cable to the ghettorigged jpole antenna I made.

I’m able to get relatively AMAZING results from this very unimpressive hack job, but it’s probably not likely to do much to my assembly skills (and lack of tuning), and more likely due to the fact that I have a beautiful unobstructed view of middle/southern Orlando from the 3rd story of my apartment balcony! I could probably wire up a rubber duck on a stick and get impressive results with that view! I’ll miss my reception when I move.

I just realized I didn’t post an image of the inside (complex wiring) of the device. Maybe later.
