Arduino launches new Nano board range
Arduino has established itself as one of the leading small open source single-board microcontroller and microcontroller kit makers on the market with its designs popular with enthusiasts through to schools and universities. Founded in Italy, the company has launched its new Nano range of compact project boards that also happen to be among the cheapest it currently offers. They range in price from just US$9.90 for the Nano Every through to US$29.50 for the Nano 33 BLE Sense that includes Bluetooth as well as a range of proximity, gesture and environmental sensors.
[...]
Also new from Arduino is a MKR GSM 1400 Cellular SIM Kit. The Nano Every and the Nano 33 IoT will ship from mid-June while the Bluetooth-equipped Nano 33 BLE and Nano 33 BLE Sense will ship from mid-July.

An Open Source ESC For Brushless Motors
For something basic like a brushed DC motor, speed control can be quite simple, and powering up the motor is a simple matter of just applying voltage. Brushless motors are much more demanding in their requirements however, and won’t spin unless driven just right. [Electronoobs] has been exploring the design of a brushless speed controller, and just released version 1.0 of his open-source ESC design.
The basic design is compact, and very similar to many off-the-shelf brushless ESCs in the low power range. There’s a small PCB packing a bank of MOSFETs to handle switching power to the coils of the motor, and a big capacitor to help deal with current spikes. The hacker staple ATMEGA328 is the microcontroller running the show. It’s a sensorless design, which measures the back EMF of the motor in order to determine when to fire the MOSFETs. This keeps things simple for low-torque, low-power applications.

A Customizable Open Source Mechanical Numpad
Mechanical keyboards with reduced key counts are all the rage these days, but while those streamlined input devices might look cool on your desk, there are times when the traditional number pad or navigation keys are quite handy. Rather than just going without, [Mattia Dal Ben] decided to put together his own mechanical auxiliary input device for when the main board just isn’t cutting it.

Little Printer returns as an open-source messaging device
Berg’s Little Printer, an adorable internet-connected box that printed out tiny snippets of news, Instagram photos, and to-do lists, stopped working when the studio and its servers shut down in 2014. Now, design consultancy firm Nord Projects has brought it back to life with a brand-new app, and it added the ability to send messages between devices, as reported by Core77.

Perfecting the Open Source RC Controller
For this entry into the 2019 Hackaday Prize, [Vitor de Miranda Henrique] is working on his own version of the ultimate open source remote control. His design follows some of the trends we’ve already seen in terms of outward design and hardware expandability, but also branches off into some new territory with features such as dual integrated displays.

HestiaPi Touch open source Raspberry Pi smart thermostat
This month Google has made a number of changes to its Nest smart thermostat platform and services, some of which will have a profound effect on the integration of the thermostat with other Internet of Things services. If you are interested in moving away from corporate smart thermostats a new open source thermostat specifically designed for controlling HVAC and water systems has been created by the team at MakeOpenStuff.
The HestiaPi smart thermostat is powered by integrated Raspberry Pi Zero W to offer wireless connectivity has been equipped with the 3.5-inch LCD display together with a host of sensors to monitor and control home heating and water. What she demonstration video below to learn more about the open source system that allows you to build your very own smart home thermostat and offer root access and increased privacy and security from the prying eyes of large corporations.

Raptor's Blackbird micro-ATX POWER9 System Is Ready To Take Flight This Week
The much anticipated Raptor Blackbird is set to begin shipping over the days ahead. Blackbird is the lower-cost (compared to the Talos II Secure Workstation) micro-ATX motherboard for IBM POWER9 systems and offers open-source firmware as currently one of the most open, high-performance systems available.
The Raptor Blackbird supports up to 8-core 160W Sforza POWER9 CPUs, two DDR4 ECC modules, one PCI Express 4.0 x16 slot (and one PCIe 4.0 x8), dual Gigabit Ethernet, 4 x SATA 3.0 ports, four USB 3.0 ports, and other standard connectivity.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
