    The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G!

    A thousand apologies to the people in this thread. I more or less left head-fi for a good couple years, satisfied with my audio equipment. Thus, when my tutorials disappeared off those free file sharing sites, I meant to transition to a permanent page on my personal website. It fell through the...

    Carrie Amp v3

    There are a couple reasons why I tried this 2 channel design.   The Mini^3 was a design by amb and morsel, used with permission. I wanted to break away from borrowing someone's design into standing on my own two feet, so to speak. I know it's more or less a Cmoy circuit, but I still have some...

    I'll be there later today. Hope to make it by around 3 or 4, but hope I don't miss too many people. Super excited!

    11th Calgary Head-Fi Meet Sunday May 31st, 2015 at University of Calgary

    @swich401 I don't know who else you messaged, but it would be worth contacting Edmonton head-fiers. Wouldn't be the first time Albertans traveled for a meet.

    Carrie USB-Powered Headphone Amplifier

    Any chance for high res shots of the bottom side of the board? All that resoldering can't be good for those traces. From your previous posts, sounds like the TL750 and DCP are both working fine independently of each other.   When I put in a tantalum caps backwards, it went up in flames; it...

    USB powered dac-amp musings

    00940, what's your take on the isolated grounds? When you connect signals L, R, and G from the DAC to the amp, doesn't that just end up circumventing the ground separation?

    Oh snap. I gotta work on my reading comprehension.

    USB powered dac-amp musings

    For my Carrie Amp proto run, OSH Park was about the same price as Imagineering per board, but I got mine in a week. Min 5 boards though. 4 sq in, so $20 per board plus $24 for ground shipping to Canada.

    Carrie Amp v3

    A guy takes a year and half hiatus and you go ahead and change everything on him? :D Presenting the Carrie Amp v3.     Yes, I'm back, and I've been silently toiling away on a new design for the past few weeks. Wow, it's great to see so many new and exciting projects here on head-fi; the...

    The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G!

    Quote: It's posts like these that get me out of bed every morning. You're very welcome.    Quote:   diyMods to date have gotten by without the high pass filter. For safety's sake, it's best to do it with the filter as the capacitor will charge indefinitely without shunt...

    The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G!

    Some of you may have noticed that I've been extremely absent from the audio scene for a long time. I'm somewhat making a comeback to the hobby, and I finally fixed one of the broken navigation frame on my website. I'm also going to be moving the diyMod and Carrie amp information to a new...
