What happened to the April issue?

Nuts & Volts (and SERVO) are changing to a bi-monthly mailing schedule (among other changes). We planned to announce this about a month ago, but we grossly underestimated the amount of time it would take to get the details worked out with the printer, fulfillment house, web developer, distributors, newsstands, periodicals, co-mailing pools, and the list goes on. It turns out the process is not as simple as just changing the mailing frequency. Who’da thought?

Anyway, since details are important, we wanted to save the Official announcement until they are worked out, as they have a way of changing. However, since just about everyone is aware the April issue is overdue, it’s probably a good time to spill the beans and quash the rumor mills. So, the Official part of the announcement is that there is no April issue on the way, and there is a new larger May issue - at the printer - at this moment.

So stay tuned – more to come in the next few days and weeks!

And as always, a HUGE thanks to our sponsors. Check 'em out!

That's It, Enjoy!

This final article in a three-part series explains how to use the interrupts and flags available in an MCP2515 Controller Area Network (CAN) controller IC, and describes how device-to-device acknowledgments work on the bus. The acknowledgment bit in a CAN frame plays a key part in successful communications and identification of errors.

Build A Custom Weather Gauge


A complete stand-alone platform for displaying data from the Internet.

This fun, elegant, and useful project pulls data from the Internet so a series of useful displays can show all kinds of cool info in real time from your mantel or bookshelf in this impressive platform.

In Part 1, we discussed the circuit and code for each of the core components for our Weather Gauge. We took a deep dive on how the stepper is wired up and the node.js code that drives it. Now, it’s time to put it all together and light it up in this final installment.
