While parents of 30 years ago had to settle for audio-only baby monitors, if you take a trip down the baby aisle at your favorite big-box store today, you’ll find that the technology has advanced significantly. Not only can you hear sounds, but you can also get night vision, room temperature readings, and probably all…
FriendlyElec’s open source two new SBCs, which support Android and Linux distributions including a new Ubuntu Core-based FriendlyCore distro, are identical except for the processor and RAM. The NanoPi Fire2A (image below) uses the same Samsung S5P4418 (4x Cortex-A9 @ 400MHz to 1.4GHz) as the NanoPi 2 Fire, accompanied with 512MB DDR3 while the NanoPi Fire3…
Developer Cary Wang has created a new low-cost fully featured Vector Network Analyzer that is both easy-to-use and allows S parameter export. The xaVNA two port Vector Network Analyzer offers users a typical frequency range of 137MHz to 3.5GHz, and a guaranteed frequency range of 140MHz to 2.5GHz. It has been designed to plug directly into…
Probably time manipulation is an attractive target for everyone. This project certainly makes it appear that way. YouTuber MadGyver’s glove uses a gigantic LED controlled by an Arduino Nano to allow objects such as a fan, water falling from a shower, and a spinning top to stop, slow down, and even reverse. The trick is that when the LED’s…
Bulgaria-based Olimex, which is known for its open spec OLinuXino SBCs like the Allwinner A64 based A64-OLinuXino, is shipping its open source, Alwinner A64 based Teres-A64 laptop kit, with an 11.6-in LCD, 2GB RAM, 16GB eMMC, 9500mAh battery, and an Ubuntu Mate OS. Instead of using the A64-OLinuXino SBC, Olimex designed a custom, irregularly shaped mainboard that…
A day ahead of Oculus Connect 4, Oculus has released documents for its second generation development kit. DK2 improved upon its predecessor (DK1) with a 1080p OLED display and positional tracking via an external camera. It in turn was succeeded by the Crescent Bay prototype which laid the foundation for the first consumer version of the Rift,…
BeagleBoard.org has revealed its latest development board named PocketBeagle. It’s an ultra-tiny and open source USB-key-fob computer that’s crafted for DIYers, hobbyists, and educators. Talking about the dimensions, PocketBeagle measures 56x35x5mm. This small size makes it flexible enough for electronic projects like gaming, drones, 3D printing, robotics, etc. PocketBeagle is based on Octavo Systems OSD3358-SM 21mm x 21mm system-in-package,…
Let’s prepare the G-code, starting from the Gerber file, so to finally print our PCB. In the previous installment, we left you after having analyzed the hardware that enables us to manage our CNC by means of whichever modern computer that is not supplied with a parallel port (as long as it supplied with…
Back in 2015, California-based startup 3D Robotics seemed poised to compete for the top spot in the consumer drone market. It had a great reputation among the hobbyist community and a slick unit called the Solo. Unfortunately, the Solo’s performance and sales didn’t live up to expectations, and last year, 3D Robotics bowed out of…
Microsoft has released an early version of a free, open-source Raspberry Pi simulator that can be accessed right through a web browser. Using Microsoft’s Azure cloud computing platform the simulator allows users to code an emulated Raspberry Pi using Javascript. The simulator has three areas: Assembly area, that displays the emulated project board. Coding area Integrated console…
The new Gigabyte’s GA-SBCAP3350 offers more power and modularity than its main rival: the Raspberry Pi. This sbc measures 146 x 102mm, which is nearly twice the size of the Raspberry Pi at 85 x 56mm. Gigabyte’s board looks more like a PC motherboard, and in some ways it works like one. Gigabyte built this board with a Copper PCB…
