    Cool that you have a Pre-soldered version, if people don’t have a soldering kit. Or if they’re lazy 😉 XD

    I ordered the KIT version. Everything was included and well labeled. The finished Product looks very Nice and professional. Soldering was fun because everything is through hole compontents. I would prefer MicroUSB or USB-B connector instead of MiniUSB (because MiniUSB is some kind of rare these days).
    Volume control is totally fine but a little bit loose because of the way it is soldered to the PCB. If you use it without a case you should not bend it too often. Im thinking about a blob of hotglue between the POT and PCB just to make it a little bit less bendable… Last thing : I love this device <3

      I have discovered I don’t really change the volume much at all since I’m using external speakers with it (which have their own volume control) and I’ve thought about removing the volume control and replacing it with some resistors, setting it at a permanent volume level.

    Very excited about bit of kit. does midi music software like cakewalk talk to this device. my 98win mobo passed away and my SB has no slot for a home.

      I would think if it worked with a regular ad-lib Card, there’s a good chance it would work with this.

    I finally got around to soldering this together tonight, and the process was not overly difficult. As long as you have some soldering experience, it is a very doable project. I was excited to get this so that I can have some sound on a couple of 486 laptops that I own. I had originally picked these up for retro gaming, only to realize afterwards that they had no sound card capabilities. I’ll also be 3D printing the case for it sometime this week. I think it will work to both protect the volume knob and make it look more polished. I too think a dab of hot glue on the back may be a good idea if you use it much at all.
