An important component of the acrylic badges I’ve been making is the artwork displayed in the center. In order to get quality results, here’s a bit of information on how to put together artwork for them. Engraving is done on my CNC machine with a V-bit. Instead of a typical cutting device’s flat end, it is shaped in a V. This allows it to cut smaller or larger holes depending on how far down it is plunged into the material.

I periodically decide to rewrite syfaro.net in some different language or framework in an attempt to make it easier to manage or update. It generally has always served the same purpose though, a homepage for my contact information or projects. In an attempt to add interesting content to this blog and keep in theme of talking about this site, let us take a look through what the Internet Archive’s Wayback Machine has to say about the previous versions of my site.

I finished creating the first PCB for the prototypes and it seems to mostly work. As of right now I’m still having issues with charging through the Micro USB port, I believe something is wired incorrectly. Additionally it seems to discharge the battery overnight, suggesting current is still running somewhere it shouldn’t be while powered off. PCB with components soldered on While the soldering job isn’t very pretty, it does seem to do the job.

In an attempt to make it easier for users to quickly respond, I’ve created a small web app called Peppershrike. Here’s an example of how it works:

I’ve been attempting to design my own PCBs for the badges. Using the same machine I engrave the acrylic with, I can engrave copper boards to create traces and drill holes. It seems to struggle with 10mil traces but the 20mil traces pictured below all look fully intact. Now that I have boards that seem like they should work, I need to order the parts. My current part list includes:

Hi all, I’m writing this as an update for what I plan to happen regarding the LED badges. Based on the experience Rynwar and I had with them at BLFC, there’s a huge demand for something like these. In attempting to research what other people have done, I’ve run across a few other similar things but nothing quite as advanced in terms of color patterns and brightness. There are a number of people who print art onto acrylic or have laser engraved acrylic using art provided by the client.

I have a blog now! Maybe I’ll actually do some useful things with it.
