Hi all,
Not sure if it is appropriate to share here, as mine is such a small one compare to the biggies here (which all look very cool!).
I've recently made a pair of AAW W100 (CIEM). So I decided to pay a little to upgrade my gear (which was an iPhone). I bought a second hand iPod mini, and followed the guide on this board to have my iPod mini modded. Now I have a modded line-out bypass, why not making a dock cable and amp myself? I then made a dock cable with 3.5 out with micro USB for charge and data sync.
Get long story short, I decided to start with an old, but simple design - an A47. Here I would first of all thank Tangent's website, which helped me a lot on electronics basics.
I've been making a few HPAs back in few years ago, those are "giant" (able to case 4x 9V cells in, you can imagine) and they are not portable at all. This time I tried to challenge myself to house it in a smaller case.
In terms of size I am quite satisfied
There are few areas to improve though, it is running with 2 LiPo cells, but there is no charge nor protection circuit, I had a few bad experience of over discharge and damaged 1 or 2 pack of cells.
Next up I would like to challenge myself with MINT, with few modifications after digesting Tangent, as well as other materials, and understanding the circuit.
