Review: New 3G and Cat-M1 Cellular Hardware from Hologram

Posted on by

In July we reported on the launch of the Hologram developer program that offered a free SIM card and a small amount of monthly cellular data for those who wanted to build connectivity into their prototypes. Today, Hologram has launched some new hardware to go along with that program.

Nova is a cellular modem in a USB thumb drive form factor. It ships in a little box with a PCB that hosts the u-blox cellular module, two different antennas, a plastic enclosure, and a SIM card. The product is aimed at those building connected devices around single-board computers, making it …read more

LAMEBOY is Handheld Gaming on the ESP8266

Posted on by

We’ve had our eye on [davedarko’s] LAMEBOY project for a while now, a handheld setup in roughly the same form factor as the classic Nintendo Game Boy. It’s remarkable how approachable portable electronic design has become, and that’s really what makes this interesting. The design is beautiful, and the closer you look, the more respect you have for what [dave] is doing.

Right now his proof of concept has a 3D printed enclosure whose face is the printed circuit board. We love how the lower left corner of the PCB slips under a pocket in the case, which makes it …read more

Milling a Flow Sensor to Safeguard a Laser Tube

Posted on by

Powerful lasers get powerfully hot and if you don’t keep them cool you’ll pay the price. After two such experiences [NixieGuy] got smart and milled this flow sensor as a failsafe.

Laser cutters are awesome. But acquiring one can be expensive, and keeping them in working order is no small feat. From the gunk that builds up as a byproduct of vaporizing the cutting stock, to keeping the optics focused correctly, it’s a game that forces you to become a laser cutter operator and not merely a user. One of the worst things to deal with is having to replace …read more

We’re Using the Word Firmware Wrong

Posted on by

I had an interesting discussion the other day about code written for an embedded system. I was speaking with Voja Antonic about ‘firmware’. The conversation continued forward but I noticed that he was calling it ‘software’. We later discussed it and Voja told me he thought only the parts of the code directly interacting with the microcontroller were firmware; the rest falls under the more generic term of software. It really had me wondering where firmware stops being firmware and is merely software?

The topic has remained on my mind and I finally got around to doing some dictionary searches. …read more

Have Some Candy While I Steal Your Cycles

Posted on by

Distributed computing is an excellent idea. We have a huge network of computers, many of them always on, why not take advantage of that when the user isn’t? The application that probably comes to mind is Folding@home, which lets you donate your unused computer time to help crunch the numbers for disease research. Everyone wins!

But what if your CPU cycles are being used for profit without your knowledge? Over the weekend this turned out to be the case with Showtime on-demand sites which mined Monero coins while the users was pacified by video playback. The video is a sweet …read more

Huge Names Confirm Their Supercon Appearances

Posted on by

We’re excited to announce the next batch of speakers for the 2017 Hackaday Superconference.

We are especially pleased to welcome Michael Ossmann as a speaker. He presented an RF design workshop at the 2014 Superconference which was sold out, standing room only, and still turned away dozens of people before becoming a hit on the Internet. This year he takes the stage with colleague Dominic Spill as they focus on infrared communications and the uses and abuses of such.

Dr. Christal Gordon threw down an incredible talk on biologically inspired sensors last year and we suspect she will outdo herself …read more
