#oggstreamer – THT components soldering

I just soldered the remaining THT components for 3 OggStreamers, and I want to share the following picture with you:

For those of you, who are unfamiliar with the terms THT and SMT. I want to briefly explain the difference: THT (through hole technology) are components that are mounted by sticking the lead through a drilled hole. Where as SMT (surface mount technology) components are placed on the surface of the PCB-Board. In this project the soldering of the SMT was done by a Pick’N’Place machine, and the THT components were soldered by hand (by me 🙂 )

#oggstreamer – 12 pcs. SMT soildered

Yippie – the kind and helpfull people at Abatec did the pick’n’place of 12 OggStreamer-Boards. The next step is the assembling the devices, the mechanical works are already on their way – so maybe next week their will be 12 fully assembled OggStreamer devices. I have to note that from this first batch only selected Beta-Testers will get a device.

The software still needs some improvement, currently I am facing problems running the icecast2 Server under uclinux. icecast2 consists of 4 threads and only 2 of them start when I start the program. It could be a out-of-memory issue, but some how I doubt that. It definitely needs some remote- or printf-debugging to get the program running – apart from that I am thinking of fine tuning the Input- and Output amplifiers. Maybe I will take away the output OPA, as the VS1063 already handles about the same current. The OPA was placed in the design, mainly for ESD-Protection, but I will experiment, whether the R-C combo is good enough.

If anybody of you is interested in the obtaining a Bare-PCB of the current Rev1.0b design, there are five pieces, which I would give away for a small project donation.
