Panelizing Boards The Easy Way

Posted on by

For reasons that will remain undisclosed until some time in the future, I recently had a need to panelize a few PCBs. Panelization is the art of taking PCB designs you already have, whether they’re KiCad board files, Eagle board files, or just Gerbers, and turning them into a single collection of PCBs that can be sent off to a fab house.

If you’re still wondering what this means, take a look at the last board you got from OSH Park, Seeed, Itead, or Dirty PCBs. Around the perimeter of your board, you’ll find some rough spots. These are ‘mouse …read more

Glitchy Synthesizer Meets Honeycomb LED Matrix

Don’t watch [Jason Hotchkiss]’s video if flashing lights or bleepy-bloopy synthesizer noises give you seizures. Do watch, however, if you’re interested in a big honeycomb-shaped LED matrix being driven at audio frequencies through a dedicated square-wave synthesizer that’s built in.

The LED panel in question is housed in a snazzy laser-cut, honeycomb-shaped bezel: a nice change from the standard square in our opinion. The lights are 1/2 watt (whoa!) whites, and the rows and columns are driven by transistor drivers that are in turn controlled by shift registers. We’re not entirely sure how the matrix is driven — we’d love …read more

[mfaust] wakes up in the morning like a regular person, goes to work like a regular person, types in tedious commands for his software versioning utilities like a regular person, and then, as a reward, gets his coffee, just like rest of us. However, what if there was a way to shorten the steps, bringing us all closer to the wonderful coffee step, without all those inconvenient delays? Well, global industry is trying its best to blot out the sun, so mornings are covered there. [Elon Musk’s] thinktank proposed the hyperloop, which should help with the second step. [mfaust] built …read more
