Epic Hardware Hacking Weekend

It turned out to be quite an epic weekend of building boards and getting things up and running.  It’s good to be back in the groove with my own electronics projects – it’s been far too long that I’ve been away. As a wrap-up to the weekend I thought I’d put together a bit of ...

Custom PCI Express Riser

One of the other boards I had in the latest order is an oddball PCI Express 1X riser card, which I could not find commercially.  In trying to figure out how to plug a PCI Express parallel port card into my little 3.5″ Atom motherboard, I couldn’t come up with a way to make it ...

From the Trenches: Embedded Platform Work 5

I’m tinkering with a new platform for my embedded projects, based on the NXP LPC1768, which is an ARM Cortex-M3 chip. I picked up an eval board (the Blueboard LPC1768-H) back in late 2010.  The board is nothing to write home about, and has some design choices that I seriously question (like non-0.100″ aligned headers… Really guys? ...

The Hammer

I thought I’d try to get one more design into the January 23 Laen PCB order.  For the new CNC electronics setup, I’m going to be using a 3.5″ form factor Atom PC motherboard.  It unfortunately does not have a parallel port, which I need to talk to the FPGA card.  However, the board does ...
