I AM 8-BIT

Here is an old Cube that I had while I was an intern. Did the post-it decoration during my lunch hour. In fact, the company workers were reluctant at first (saying it was too flashy). However, they kept it up for two years after I left and gave no one my old cube until they ran out of space. People found it cheery! yay for smiles! First Summer was very early pre-nintendo video games, next Read more…

Are you interested in a microamp with digital control?

Hello guys! Well, I have a couple of projects and I would like to make this next one open source! As you may know, in my day job I do a lot of programming and stuff with micro-controllers. Well, I have designed an ultra small portable amplifier with digital volume control. This one is designed to be powered by a single 3.7v Li-Ion and charged from a USB port using a MicroUSB or MiniUSB connection. It Read more…

Sometimes, you need to fix the Bad engineering it came with.

So this was basically a Portable FLAC playing mP3 player that had a built in Headphone amplifier. It wasn’t bad sounding at all when used as car audio input or with medium impedance headphones (32ohm-150ohm), but for portable earphones and high end portable headphones it was a nightmare. All kinds of impedance mis-matching, sensitivity issues, chip oscillations, etc. Good news is that most of this could be fixed! Problem:1. They used horrible SMD electrolytic capacitors Read more…

Modified and Refined SS Tube-Hybrid headphone amplifier

Hey guys, I though that I might post some of my refined and modified Pete Millett “starting student” headphone amplifier designs. Originally, this was a headphone amp that was supposed to cost about $50-75 before buying an enclosure and have very hi-fi sound for easy build and low cost. I have built about 4 of these and one of which is completely unique, even a rarity among hi-fi tube amplifiers as this headphone amp had Read more…

Back when I liked the iPod Touch and the iPhone

This is just some stuff that I had made when I was stuck in the iPod/iPhone universe. Switched to Android in June and have not looked back, except for the pictures that is. * Likely the smallest iMod/DIYMod iPod ever made with Film capacitor dock. It uses an iPod Touch 1G which was taken apart and the DAC outputs relayed out to the dock connector. From there a standard iPod dock connector connects to an Read more…

You like Open Source Hardware? – sign NOAW

Hey guys, Just wanted to send my endorsement for the OSHW principles and definition.OSHW Read and EndorseThis is a VERY valuable sent of guidelines that not only encourage new projects being shared, but also to help those who use open source hardware, much like software, to know what is appropriate and how to treat the original piece of which you are using or distributing. Considering that most of the progress made in recent years regarding sensor networks or Read more…

What ‘Cha Gonna do?

So as a little blurb for what this blog is going to be about:  1. Stuff I am up to (building, designing, hacking)2. Stuff that people I know are up to 3. Stuff I think is cool4. Occasional Girly-geeky-nessA few words about myself: I am a Technology Enthusiast who is female and also into music/art/etc. I build things that are technology or non-techno related (music). I design circuits and software, play around with high end mobile Read more…
