$200 Omega2 WiFi LIDAR Kit Comes with a 360˚ 2D LIDAR Scanner

Omega2 Wireless LiDAR kit

Onion Omega2 is a tiny WiFi board running OpenWrt that launched for as low as $5 via a crowdfunding campaign around 2 years ago, and at the time I reviewed Onion Omega2+ board – which comes with more memory and storage – together with its dock, and I found it was fairly easy to get started with the solution. You can now buy the board for a little over $10, but the company also offers kits, and their latest product is Omega2 wireless LIDAR kit with an indoor 360˚ 2D LiDAR scanner that uses rotating laser ranging to measure and map exact distances to indoor surroundings. The kit is comprised of the following items: Onion Omega2+ board with MediaTek MT7688 MIPS processor, 128MB RAM, 32MB flash Power Dock 2 with 30-pin expansion header and USB host port Delta2B 360˚ LiDAR Scanner Up to 5000 samples/second Range – 0.2 to 8 meters Scan Rate – 4 ~ 10 Rotation/Sec Laser – …

Linux 4.19 Release – Main Changes, Arm and MIPS Architectures

Linux 4.19 Changelog

With Linus Torvalds taking a leave from the Linux kernel project, Greg Kroah-Hartman was the one to release Linux 4.19 last Sunday: Hi everyone! It’s been a long strange journey for this kernel release… While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone. A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so the next -rc1 merge window is going to be bigger …

Linux 4.18 Release – Main Changes, Arm and MIPS Architecture

Linux Changelog 4.18

Linus Torvalds has just announced the release of Linux 4.18: One week late(r) and here we are – 4.18 is out there. It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announment as “pending”) and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering fix). Shortlog appended for the (few) details. Some of these I was almost ready to just delay to until the next merge window, but they were marked for stable anyway, so it would just have caused more backporting. The vfs fixes are for old races that  are really hard to hit (which is obviously why they are old and weren’t noticed earlier). Some of them _have_ been seen in real life, some of them probably need explicit help to ever …
