IO-Module Prototype #002 Testing
Monday, January 21, 2008 1:01:53 AM (Central Standard Time, UTC-06:00) (  |  )
Okay, so I got the latest prototype PCB for the IO-Module... time to build prototype #002.

I usually build 2 to 5 prototypes before the kit goes on sale. I want to make sure that it works, that everything works right and performs great, easy to assemble, the parts list correct and all that. It's the DETAILS that matter!

Some pics...

Since the PCBs are prototype, there are no cutouts for the transformers. On the final production PCB, the holes will be cutout by the factory.



So we drill some 3/8" holes on each corner of the square cutout.




And here's a pic of the drilled PCB.



Using a jig saw, we do a rough cut of the square hole... then use a file to smoothen the edges.



Next, we test fit our transformer (Cinemag CMOQ-2S) into the PCB... fits perfectly on the 1st try!



Here's the bottom view.



And a photo showing both the input and output transformers.

Mini-IO PCBs are here!!!!
Saturday, January 12, 2008 5:31:36 AM (Central Standard Time, UTC-06:00) ( )
This MINI-IO is very fun and easy to assemble. Within a few minutes, you could have a completely assembled kit.

To re-iterate... this kit gives you POLARITY CONTROL, -20dB PAD, and MIC/INST select switch, plus an onboard ACTIVE DI with fully, electronically balanced outputs.

It is a stripped-down version of the IO-MODULE. The only difference being the IO-MODULE has provisions for input and output transformers.

The MINI-IO is meant to be used in conjunction with a preamp module. It works with the SC-1 preamp kit, or any preamp you're working on where you wish to add the above controls and features.

Power Supply Requirements are +18/-18, +48V for phantom power.

CNC Machine

I finished assembling my CNC. (Got it from eBay)... Using Mach3 software... It's a complicated piece of software but I think I'm getting the hang of it. I'll probably buy it after I play with it some more.

Tested the CNC doing some movements and "pretending" to cut/route something... I need to buy a router to install to it so it can do some real cutting.

Some photos:
