Cheap, Full-Duplex Software Defined Radio With The LimeSDR

A few years ago, we saw the rise of software-defined radios with the HackRF One and the extraordinarily popular RTL-SDR USB TV tuner dongle. It’s been a few years, and technology is on a never-ending upwards crawl to smaller, cheaper, and more powerful widgets. Now, some of that innovation is making it to the world of software-defined radio. The LimeSDR Mini is out, and it’s the cheapest and most capable software defined radio yet. It’s available through a Crowd Supply campaign, with units shipping around the beginning of next year.

The specs for the LimeSDR mini are quite good, even …read more http://pje.fyi/Ppt90T

False Claims On Kickstarter: What’s New?

Kickstarter and its ilk seem like the Wild West when it comes to claims of being “The world’s most (Insert feature here) device!” It does add something special when you can truly say you have the world record for a device though, and [MellBell Electronics] are currently running a Kickstarter claiming the worlds smallest Arduino compatible board called Pico.

We don’t want to knock them too much, they seem like a legit Kickstarter campaign who have at time of writing doubled their goal, but after watching their promo video, checking out their Kickstarter, and around a couple of minutes research, …read more http://pje.fyi/PbggsY

Friday Hack Chat: Crowd Supply

Crowdfunding is a mixed bag, at best. On one hand, you have fantastically successful products like Pebble, Oculus, and the Kano personal computer that managed to take in money, turn out a product, and become a successful company. (If even just for a while, the Pebble was great.) On the other hand, you have obvious scams like a color-picking pen that are run by a literal Nigerian scammer.

Crowd Supply is different. Unlike other crowdfunding platforms, to get on Crowd Supply you’ll need a working prototype. Where other platforms can measure their success by how many campaigns were successfully funded, …read more http://pje.fyi/PZh3KD

Monoprice Releases Their Mini Delta Printer (On Indiegogo)

Around this time last year, Monoprice quietly unveiled a small, $200 3D printer. At the time, a fully functioning printer at this price point wasn’t unheard of. A good 3D printer at this price point was. It turned out this printer was actually fantastic and completely changed the value proposition of desktop 3D printers.

In the year since the release of the MP Select Mini printer, Monoprice has been hard at work bringing costs down, reworking designs, and creating an even less expensive printer. Now, it’s out. It’s available for pre-order on Indiegogo right now. Is this still a $150 …read more http://pje.fyi/PB5Mry

A Wireless Oscilloscope Isn’t As Dumb As It Sounds

The latest CrowdSupply campaign is a wireless, Bluetooth oscilloscope that doesn’t make a whole lot of sense until you really think about it. Once you get it, the Aeroscope wireless oscilloscope is actually a pretty neat idea.

If the idea of battery-powered, Bluetooth-enabled test and measurement gear sounds familiar, you’re not dreaming. The Mooshimeter, also a project on CrowdSupply, is a multichannel multimeter with no buttons, no dial, and no display. You use the Mooshimeter through an app on your phone. This sounds like a dumb idea initially, but if you want to measure the current consumption of a drone, …read more http://pje.fyi/NhfRVN
