On a Quest for the Perfect Numpad

Posted on by

Often times, the only way to get exactly what you want in a device is to just build it yourself. Well, maybe not the only way, but we’ve all certainly told ourselves it was the only way enough that it might as well be true. We don’t know if the DIY imperative felt by [Olav Vatne] to construct his own Bluetooth mechanical number pad was genuine or self-imposed, but in either event, we’re glad he documented the process for our viewing pleasure.

Broken up into three separate posts on his blog, the construction of his custom numpad starts innocently enough …read more

Sometimes they are open networks such as The Things Network, other times they are commercially available networks, and then, of course, there are entirely private LoRa installations.

If you are interested in using LoRa on a particular site, it’s an interesting exercise to find out what LoRa traffic already exists, and to that end [Joe Broxson] has put together a useful little device. Hardware wise it’s an Adafruit Cortex M0 …read more

Hackaday Prize Best Product Finalist: PewPew

Posted on by

This year for the Hackaday Prize, we’re doing something very, very cool. We’re encouraging hardware entrepreneurs to come up with the next big electronic thing. We’re giving the Best Product in the Hackaday Prize $30,000, and an opportunity to work in a lab filled with tools to turn that prototype into a marketable reality.

Last week, we announced the twenty finalists of the Hackaday Prize Best Product competition. There’s still a lot of work these hackers and tinkerers need to do before the final judging round, but until then we can start taking a look at what are already some …read more
