I believe that Colin is on the money. It is a Jaycar pot, and can be found here.

Dame you've found my secret supply, it is a Jaycar 10k log

Merry Christmas

Some great DIY work going on in here!
Keep it coming...

a new kit, for me. called 'tiny IR2' it is a learning (!) IR receiver/decoder that can learn 12 IR commands (can be from diff remotes if desired) and assign them to 12 output pins:



cost was in the $25 range for the programed (locked) PIC, pc board and parts shown.

setup was easy - you program what features you want via some hard-soldered diodes. that configures which buttons or pins are toggle vs momentary style. you get 'free' latches that way (for on/off, or mute or crossfeed or bass-boost).

2 of the pins will be used for motorized volume control.

the button on the board is the 'learn' button; you press that while powering up and then you go thru the 12 IR commands you want and on the 12th one the LED turns out to tell you it learned all 12 and learning is now done.

the output are high-going on button presses.

I plan to integrate this in my 'all in one' preamp/dac/etc box.

Pretty cool. Thanks for the tip...

Probably not your most typical build but I thought I would post a few of the images here.

The first pair I made as a Christmas gift and can take all credit for the gruelling work , the second was much easier as Smeggy kindly sent me unfinished cups some time ago and with the recent stormy weather and inability to move about easily, I had some time to finish them up.

They are SFI based headphones - details on the ortho thread for anyone not intimidated by monster threads.

My first amps: 2 Cmoys

hi all - so here's my first 2 amps - first did a cmoy in an old ferrero rocher see-through case (no drilling needed), then one in an old Dysan stiffy disk box...
both are pretty close to tangent's original schematic, cept for some improvement to caps values, etc. I use wallpower for both - and the second i fine-tuned more to my purposes - gain of 5.7, 1/4 inch output jack. Both use the opa2107 and sound really good - enjoying them...

Never would have thought of the old disk box. I'm sure I've still got some, (somewhere)
Glad the amps are working well, they always sound better when you build them yourself.

A pic of the work in progress... this is my very first DIY project.
I'm working on it under supervision of a Dutch electronics engineer/designer.

Looks really nice!
You say its a work in progress, if so I can't wait to see the end result.

Welcome to Head-Fi!

my first (ever) toner transfer pc board! its a control board for IR remote control (it does 'radio button' selector so that when you select 'toslink' it 'pushes out' the spdif and analog inputs and so on):



its just a large OR gate going into 3 d-latch flipflops but it does hold the last pushed button state and 'pops out' all the others.

I used eagle and some photo paper to iron on the pattern to board before I etched it.

one thing, though; always remember to mirror-image the graphic or you'll end up soldering and placing parts on the opposite side of the board (doh!)

this is probably the first home-etched pc board I've made in perhaps 30 years! and I think my radio shack etchant was THAT old, too.

Thanks. And yes, it’s still work in progress. Not sure when this amp will be completed but I think more likely early in the New Year.

Basically it's a SOHA II, revised by a friend (knowing as Ferrari here at HF) and is building by me.
Actually, there are 2 amps in the making at the same time. Ferrari’s amp differs from mine by some special parts.
In any case, I need his help to round up the measurements of my amp (not because I’m a woman , but because I’m using his oscilloscope and audio analyzer) and of course, for the parts of the circuits that were revised by him.

Undoubtedly, his amazing style is also visible on my amp. DIY-gurus like amb and Ferrari are really the inspirations for many of us.

that's a very clean looking front panel and layout.

well done. not over-done, either

That is funny as I was going to ask you if your friend was well known to us

Very good looking build, I am sure it will perform admirably too ..dB

As soon as she said a dutch.... etc i knew it was going to be Ferrari then i read the next post...lol

I could see the masters influence in the case design.
