Posted by Charbax – March 23, 2017

SCEWO is a stairclimbing wheelchair equipped with a Toradex Apalis iMX6 SoM - born from a master’s degree thesis from Zurich University (ETH), which demonstrates what can be done using Toradex Computer on Modules (CoMs)/System on Modules(SoMs) in safety-critical applications. Other engaging demos included TAQ, the balancing robot, featuring Toradex’s Colibri iMX7 SoM with NXP i.MX 7 processor, a rover using the Apalis TK1 SoM with the NVIDIA TK1 to recognize street signs, and many more at Toradex’s booth at Embedded World 2017. Toradex also mentioned its launch of two new SoMs based on NXP i.MX 8QuadMax and NXP i.MX 6ULL: Apalis iMX8 and Colibri iMX6ULL respectively. The Colibri iMX6ULL offers a low-cost and power efficient platform, along with integrated Wi-Fi and Bluetooth, targeting the emerging IoT and connected market; and the Apalis iMX8 offers high-performance and powerful graphics for Computer Vision applications.

Qualcomm Snapdragon at Embedded World 2017

Posted by Charbax – March 20, 2017

The Qualcomm Snapdragon platform is originally designed for mobile, but now can be embedded into Interactive kiosks, Digital signage, Robotics, High-tech toys, in flight entertainment, medical imaging and all kinds of ideas for any advanced IoT. Qualcomm positions their Snapdragon processors for Embedded to provide a superior performance, low power consumption and integrated connectivity to make devices more aware, connected, intelligent and interactive. The Snapdragon platform offers development kits, single-board computers and scaling up to customer solutions, integration services and production-ready, customizable System-on-Modules (SOMs). At Embedded World 2017, Qualcomm talks about Snapdragon 410E, Snapdragon 600E and also talks about the upcoming 820 series for embedded all with long term support (at least until 2025) to provide their maximum performance. With many projects to be born out of the Dragonboard 410c and showing off other solutions such as the Geniatech Developer Board 4, the small Geniatech DB4x 410 based module, the Altierre Systems powered embedded vision real-time synchronized multi-camera 130-degree panorama 4K system that is in the Panacast 2, eInfoChips eragon 820, Inforce, Kiteboard Snapdragon 410 board with a LTE sim card slot and more. All these Qualcomm Snapdragon based Embedded products can support multiple operating systems Android, Linux thanks to the availability of the open source Freedreno GPU driver and Windows 10 support also.

Zephyr Project, open source OS for IoT

Posted by Charbax – March 20, 2017

Matt Locke, Director of the Linaro IoT and Embedded Group (LITE) and Maureen Helm of NXP, one of the maintainers of the Zephyr Project which is a Linux Foundation hosted open source collaboration project, uniting leaders from across the industry to build a best-in-breed small, scalable, real-time operating system (RTOS) optimized for resource constrained devices, across multiple architectures. The Zephyr Project’s goal is to establish a neutral project where silicon vendors, OEMs, ODMs, ISVs, and OSVs can contribute technology to reduce the cost and accelerate time to market for developing the billions of devices that will make up the majority of the Internet of Things of the future.

The Zephyr Project is perfect for building simple connected sensors, LED wearables, up to modems and small IoT wireless gateways. Because the Zephyr OS is modular and supports multiple architectures, developers are able to easily tailor an optimal solution to meet their needs. As a true open source project, the community can evolve the project to support new hardware, developer tools, sensor and device drivers. Enhancements in security, device management capabilities, connectivity stacks and file systems can be easily implemented.

3of3 4K60p Panasonic GH5 handheld sample footage, testing 5-axis, autofocus in manual mode

Posted by Charbax – March 20, 2017

Here's my third attempt at making a sample footage at 4K 60p using the new Panasonic GH5, with the help of one Panasonic staff, he used what he thought could be the optimal settings in manual mode to try to demonstrate the 5-axis stabilization, the auto-focus always following and tracking my eyes and face automatically, focusing on devices that I hold. You can download the original 4K 60p 150mbit/s MP4 camera file here on Google Drive.

1of3 4K60p Panasonic GH5 handheld sample footage, testing 5-axis, autofocus in Program mode

Posted by Charbax – March 20, 2017

Please try to ignore my big mistake in not controlling the Shutter speed in this video to prevent to the terrible flickering of the indoor LED lights once we enter the building. I am very sorry I didn't try to adjust the shutter speed while shooting or before hand. I also tried but I couldn't find any easy and fast Anti-flicker post processing options in a video-editor. So here it is, I publish this video as I filmed it anyway. You can still see the GH5's performance in its 5-axis stabilization, auto-focus, color quality in 4K 60p mode. This video features Interview with Kevin Walker of Panasonic UK and Nick Driftwood a photographer who has been testing out pre-production GH5's over the past 3 months and you can see some of his GH5 samples at https://youtube.com/driftwoodtv and https://vimeo.com/user2930807 I'm sorry I didn't ask Kevin or Nick to help me adjust the Shutter speed while shooting this video when I should have better noticed the flickering in the viewfinder.

2of3 4K60p Panasonic GH5 handheld sample footage, testing 5-axis, autofocus in shutter priority mode

Posted by Charbax – March 19, 2017

Filmed on Panasonic GH5 with manual settings (in shutter priority mode, 400-iso then trying to change the iso setting) filmed with Kevin Walker of Panasonic UK at The Photography Show in Birmingham UK. As this is my second time trying to use the camera, I have probably not set all the settings just right, and this was shot on a pre-production model with possibly a non-final firmware for now, please check back later as I will post other samples that I shot with the GH5 today using other settings as I was trying to achieve perfect auto-focus, perfect 5-axis dual image stabilization, perfect anti-flicker, perfect brightness, perfect colors and etc with the types of handheld always moving camera movements that I usually do in my video-blogging. Check back a bit later tonight as I will attempt to de-flicker the first 25-minute video that I shot with the GH5 in its more default P mode but where my shutter speed was set incompatible with the indoor lights flickering too much at the show. I will also try to upload a couple more samples that I shot on the GH5 in 4K 60p. You can download the original 4K 60p 150mbit/s MP4 camera file here on Google Drive.
