Populated the FAB2010 boards tonight. I put too much solder paste on my resistors so I need to be careful doing that. It’s a little hard because I’m just using a plunger to dispense the paste. I need to get one of those solder paste pump dispenser. I’ve seen them on eBay for around $150 or so.
Anyway, here are some pictures.
Received our FAB2110 Input Transformer Module. Looks good. No corrections needed, it’s just a very simple PCB. You can use a Jensen, Cinemag, Altran, EA Input Transformer for this PCB.
So let’s say you have a few of these FAB 2110 boards, you can solder a different kind of Input Transformer on each FAB board, and you’ll be able to swap them in and out in your circuit, and compare the sound flavors of each other.
Why am I running a blog? Why am I posting development updates, when there’s no audience yet other than the accidental visitor or web spider bots?
I’m posting this blog as a way to document my journey of launching this new product/concept. It’s a way to keep my thoughts/ideas/plans/to-do list off my head, and onto to this blog. That way, I can review what needs to be done, what has been done and how far we’ve come along. It’s also a good way to keep track of my progress, problems I’ve encountered and it’s solutions, and basically an accountability partner. It helps me focus on what’s next that needs to be done. So yeah, even if there are no other readers or audience to this blog, it’s serving a very important purpose and a very important audience — me.
I’m working on my FAB2010 XLR Input Module and getting ready to populate it. So far, I’ve noticed already a problem with the XLR jack…. it’s off by a few millimeters positioned on the board.
That’s the problem… I trusted the Eagle library for the XLR jack to be 100% correct. It’s not.
Received the FAB2010 XLR Input Module today. I’ll have my SMD parts coming in the next few days, then I’ll be able to build the first prototype in my “Reflow Oven”… i.e. a stock Toaster Oven. I’ll make a post about my experiences with my “Reflow Oven.”
To recap, the FAB2010 module features a Neutrik PCB mounted XLR jack, logic level control for phantom power, and -20dB pad. In addition, it features a soft-start phantom power. i.e. The 48Volts is raised slowly, instead of being switched on abruptly. This prevents loud mic popping when turning on phantom power since the 48volts is applied gently your expensive microphones.
