I've been using my hands for the last 8+ years!

 

Then I shall expect nothing but absolute perfection from your soldering work when my P-H unit arrives. wink.gif

 

A lead bender is just a triangular piece of plastic you use to bend the leads of a resistor/whatever against. It just ensures the lead pitch is always the same, and I always use mine because it's just as fast, if not a little faster than bending by hand, and it gives more consistent results.

a variable gain amplifier costs waaaayy too much.
do you guy think 64steps @ 1db is enough?

Yes, 64 steps is excellent, if not too much. 2dB steps are actually small enough, 1dB is definitely small enough. (based on my knowledge of human hearing, and experience with volume adjustment)

what about 32steps @2db?

relays are expensive! biggrin.gif

Don't expect too much when I'm in mass-production mode... I'll stop caring about the fine details after the 2nd or 3rd unit. tongue.gif

What was that?, Mr. so-called Soldering Master?, is it too much effort to maintain high standards? I expected so much more from you.

 

You have your name in front of the amp, and indirectly, you represent everybody here in the thread. Keep that in mind.

 

I'm just taking the piss out of you. =P

 

32 steps is still alright, considering the DACT, a somewhat popular 'audiophile' stepped attenuator only has 24-odd steps.

Now when did I call myself that? :P

Though I have a feeling that my "standard" effort is equivalent to your "high standards"..... is what I wanted to say... but after so many problems and changes in the design, it's impossible to make it look all nice inside (or even outside confused_face.gif).

 

 

I think i'm gonna pull the trigger on 8 of these relays:

http://hongkong01.rs-online.com/web/p/non-latching-relays/6280527/

they have lights in them... shiny~ tongue.gif

 

6 for the volume (64 steps @ 1dB), 1 for power, 1 for output muting.

How are you actually going to design the stepped attenuator? Won't you need a PCB for that?

How is it going to be controlled? I imagine a rotary controller won't work with relays, so I assume it's going to be digitally controlled?
Are you going to design a new controller including PCB for the attenuator, I/O and power control? Isn't that gonna be a crapload of work?

Duh fuq. o_o. Sounds like a painful extraction.

PCB? nah, screw that. I'm going pref-board! (the min-order for PCBs is 10!)

The relays will be controlled by an ATTINY26 MCU via 2N7000 MOSFETs,

Volume control signal is controlled by a linear pot which feed a DC voltage to the ATTINY26's on-chip ADC.

The ATTINY 26 will also control power going to the sigma22 (supplying 4 beta22s and a preamp) and the output muting relay which stops any on/off clicks and pops being audible.

LOL!!
this made me laugh so hard my CIEMs popped out..

I can't wait to rip apart my P-H unit. tongue.gif

 

Chin up bro, we'll deal with the problems as they come.

It's pretty much Australian for "I'm just messin' with ya".

Only 33 posts since last night??? What's happening? Doomsday?
post #53609 of 135541
Chihayafuru is going on awesome mode again. I was at the absolute edge of my seat the entire episode.

The use of music and sound effects is excellently timed, together with some of the best constructed 'battle scenes' I have seen. (not really battle scenes, since it's a sports anime, but it shares a lot of similarities).

The voice acting and art is good, but not excellent. The use of animation is not incredible fancy, but still of high quality. It's especially the directing that's amazing on this one.

9/10 so far.

Yeah. I thought about them being fakes. But i still wanted to rant. New keyboard smily_headphones1.gif

DAMN!!! EPIC SKILLZ!!!!!!!!!!





See this? That's right! 3 working beta22 boards!
I'm gonna fix the last one by tonight.

And you know what died? NOTHING!
All of the components are working fine.
Those are some niceu skillz indeed

Nice to see an anime thread here, kinda embarrassed I only found this now. Anyways, for those of you who are interested, I am currently holding unlimited invites to the private anime tracker Animebytes. If it sounds like something good please send me a PM, if you don't know what a private tracker is, then.. uhm, xD
Yes!! Ill take you up on that.
