Hi guys!!
 
I made Chu Moy's Amplifier into the Film Case with battery.
And I wrote build report on my webpage.

I am sorry I'm not good at English

 
Have a good day!!

Nicely done!
 
Now let's see you point-to-point a soic chip

Very cool! 
 
You could probably save a little space, and neaten things up with careful use of SMT resistors if nothing else. 
 
And bonus points for shooting Tri-X.

Thanks replies.
 
I have SOIC parts. I will try SOIC version.
The battery is too large

I wonder if a common camera battery (the flat 3.7V kind) would be doable.

Very nicely done. Reminds my of Sijosae's work.

You don't need to speak the language - just look at all the pictures of the awesome work that he did....

When I want to turn off, the cap of case to open.
 
The battery and the circuit is not directly connect to.
Circuit is connected by tension of the cap.

Now if you could build the amp into the case of the charger, that would be neat!
