2AA batteries for breadboarding

I created a part in Eagle for a 2 AA battery holder.  Ordered a set of prototype boards.  Cute but kinda pricey.  Need to validate the layout and hole sizes are correct anyhow.  Will be nice to be able to put 2 AA batteries on the breadboard.


Simplight and prototyping

I started working on a new project tonight.  I’m going to build a compact, cheap LED light that runs on a single AA battery.  I’ll be using the MCP1640 voltage regulator booster from MicroChip.

I created the Eagle-Layout for it tonight and ordered a test board from OHSPark to verify the layout.  I also created a SOT23 to breadboard adapter and ordered 3 of those as well.  That will make it easier to prototype the chip and figure out how to set it up.

I also made a variant of the TO92 package for Eagle.  I find it annoying to bend the pins for transistors when putting them in boards.  I can’t think of a good reason it’s needed so I built a straight layout for the BC517.  I added it to the test layout board that I ordered.

Ebay Listings

I listed Nanohawk products on eBay to make sure they have good exposure.  Tindie is not generating any sales.

MiniButton went live this week as well and TinyTimer and TinyTimer Duo are available.

Waiting on a new set of boards for the Kickstarter version.


Header Images

I decided to publish some of my own photographs for the header images. I’ll shoot some product photos and other electronics related photos at some point. In the meanwhile, one of my interests is Scuba diving and shooting pictures while doing it. The photos are predominantly from Cozumel, Quintana Roo, Mexico and Maui, Hawaii, United States. The flower photo is from Washington on the Brazos State Park, Texas, United States.

Open Hardware License model chosen

This evening I spent time evaluating licensing models. I looked at . I also looked at . I reviewed the information shared by . In the end I felt that the CERN license model best addressed some of the ownership, attribution, and liability concerns that developing hardware requires. I greatly appreciate the hard work that went into CERN’s You can check out the license on my site under
