Photography – B&W Series

I did not want to drag this out to much cause I want to get around to making and posting new stuff. These three photos are again, for the Elvis fans. These are of the stone wall and the graffiti on it surrounding Graceland in Memphis, TN. These are not as big because I am sure where the orginal scans are, on a disc or hard-drive somewhere in the apartment I hope.

Photography – B&W Series

Amp

Another one of my electric guitar amp. It was a really nice object to shoot, least I thought. The tweed was classic looking of a 70’s amp but had this cool metallic threading, the black wrapping on the cabinet was soft looking and non reflective and it was just cool. This photo includes some effects pedals, stands and more cabling.

Photography

I did not realize how much I miss shooting until I started again. My wife and I bought a Nikon D5100 a couple weeks ago and slowly I have started having it in my hands much more, and it feels good. My first DSLR and I love it. Originally this was purchased to record video when she preaches while in seminary. Being around it though I would snap a few photos, then a few more and so on. I still have lots of cobwebs over my rustyness though. Also the last real camera I had was when film was still widely being shot. It was a Canon AE-1 Program, which at the time I was using it was well older than I was. This new DSLR is crazy nice. Like I said I do not have tons of camera time in yet and am still getting the feeling back but I am going to include some scanned b&w’s I shot years ago that I have really liked to look at over the years. Maybe I will post a couple a every few days. Maybe some color photos too, hopefully this will really get me inspired to keep shooting.

Knobs

This was a black and white Kodak film, I am pretty sure it was probably Tri-X. It is of my guitar amp from back in the day. This photo is several years old so that is about the most detail I can give. Maybe an 85mm prime lense. This is well before my exposure to Photoshop, that is all nature.

Tube Headphone Amp ***Update***

hJust a quick follow up entry to the Tube Headphone Amp project. I’ve received updates that my PCB’s are back from the fabricator and are being processed. Specifically they are cutting down the master board into the individual orders and hopefully mine will be shipping out soon. I’m really rather excited about the project. Between getting married and this project, 2012 will end out with a hell of a bang for me. Just to specify, I did yes mention my fondness of marriage and this electronics project together. Picture this, your holding a 40 foot ladder and placing those two things on the ladder I can assure my fiancee, should you make it over to reading this post, the marriage is well up at 40 feet. My amp is probably rung number 4.

Last Project of the Year-Tube Headphone Amp

41xLzbeWL-L._SL500_AA300_This is just a little write up for you all of what I think will be my last project of the year. This one was an easy one. I did very little work on it. Mostly just a few modifications of a previous design and when everything arrives, assembly. Now as I said, not my original design this time, but that’s ok. It’s a epic design none-the-less.

What is it you ask? A Tube Driven Headphone Amplifier. Link below.
http://diyaudioprojects.com/Solid/12AU7-IRF510-LM317-Headamp/
Specifically it is a 12AU7(ECC82) Tube / IRF510 MOSFET Headphone Amplifier.

It uses one 12AU7 vacuum tube for signal amplification and a pile of other great passive components and a few semi-conductors.

So far I’m not very far into it. I have ordered all my parts. As of Sunday November 25th I have received:

  1. Groove Tubes ST-12AU7 Preamp Tube Silver – Link
  2. 9-Pin Tube Socket Ceramic PC Mount – Link

Printed Circuit Board – PCB

In addition to all that I’ve also out-sourced my PCB construction to a pretty awesome service. Which is called OSH Park. These guys, best I can tell, round up multiple orders for PCB’s and submit them as one board to there builders. This makes it worth while money wise and your not stuck with 50 copies of one board. This is what has forced me in the past to make my own PCB’s. Which I hate to do!

With this service you create your circuit board in Eagle CAD and then upload your design to there website. It will ensure a proper design and tell you how much your going to be charged. It also renders you out pretty pictures of basically how your board will look. I included mine below. Now when you order, you have to order in multiples of 3, but that beats 50 or more. I paid $21 USD for my project. Which to me, that’s not bad. I’ve got 3 boards coming, that’s 7 bucks a piece. I can sell 2 of them if need be to pay for the entire project easily.
