Soldering the Binary Burst Clock PCB

I received the boards back from Seeed Studios two weeks and four days after placing my order. I’m shocked by the quick turn-around, especially since I selected the slowest shipping option available which itself could have taken three weeks.

I’ve been pretty busy with work lately but finally found a bit of time to populate a board and get some test code running. I’m happy to report that I made no design errors. Everything seems to work as planned! Well, that is after I discovered the tiny trace bridge between two vias which prevented ISP communications with the chip. A sharp razor blade fixed that right up. I understand that this type of manufacturing error is not uncommon and it doesn’t really bother me.

Above is a fast-motion video I made while populating the second board. I’ll be sending this one to my friend Christian who is going to lend a hand adding features to the firmware. Hand soldering the mostly SMD project wasn’t too hard, but it did take about an hour. If I were making any more than two of these it would be worth it to order a stencil and procure solder paste and an old toaster oven for reflow. Perhaps on the next project.

In my next post I’ll talk about adding the LEDs. This took a long time. The first spire took about 45 minutes, by the twelfth spire I had it down to around twenty. Here’s a peek at the final product:

How did I do hitting the mark from my concept?

  1. I like the clock concept in that it’s still pretty readable by those not fluent in binary, and if you do know binary, it really makes sense. Not many binary clocks are so suited for mass consumption.
