My latest creations, the Dubnium Drive (DBA Interstellar Overdriver) and Indium Indicator (VU meter designed around the LA2284 chip). Thanks to Cody for tech help with the transistor selection, which led to me discovering a layout mistake (flipped transistors). The indium indicator is using 0805 SMD components, except for the trimpot, IC and the SS12 diode which is a bit bigger than 0805.
The layouts are shared in my oshpark account (through hole and smd version for the Drive) and build docs are linked there.
The graphics are courtesy of Peter Repovski (http://www.petrovski.com), who was nice enough to allow me to use the comic and sent me a high-res verision. Etched, painted, sanded and clear coated. Turned out perfect, but shows again I can't drill straight. ;)

The video is just to show the VU meter. The sound recording is crap with my phone.
That's amazing.

Slick etch!
That is absolutely wonderful.
I see you have constructed a new VU meter. Your skills are now complete.
I can see a few people being interested in that vu pcb, it's pretty slick :)
Great etch and VU meter use!
thanks!
I have to give credit to Thomas from THcustoms. I got the idea and parts of the schematic for the vu meter from his/merlins boost project and the rest came from the data sheet.
I have 2 1 indicator pcbs left and I could include all smd parts if someone is interested. 6€ plus shipping should cover it. Also, I've got one more drive pcb, 4€ plus shipping?
Great ergonomic design, your own PCB layout, an immaculate enclosure etch, and then there's that VU meter.....
WOW! Stellar work inside and out!
Vader with lightsaber! Yeeyah! Great job Felix ;D
Awesome! :)
That looks so good!
I'll take the drive pcb if it's still up for grabs?

thanks. It is. PM incoming
That's awesome! What a great idea!
Stunning work again. I particularly like that etch, I wish I was as skilled as you doing those etches.
Next time drilling: use a centre punch and start drilling with smaller drill sizes (I usually start with 1.5 or 2 mm) and then go bigger. From 2 to 6 mm works better than starting with 6 mm IMHO. Use new drill bits. Older or less sharp bits tend to drift away. Work exactly perpendicular on the enclosure surface and correct when the bit drifts aside by angling the drill in the opposite direction and straiten again when back at the point where you want the hole. Using a drill press is recommended but not mandatory. I can work with 0.5 mm margins sung just power tools. Good for me, I know :D but with some patience and care I'm sure you can drill almost perfect. That is, if you want that to be perfect too... You might just not care, cause this finish is already very very cool.
Love it!!
Sooo cool! Great etch also.

I'm a few days late on this, but what an etch!
Also, come on, no video of the LED meter in action? Hook us up!

Thanks. There actually is a video at the end...
