Sony Has Developed a Smartphone Camera Sensor Capable of Recording 1080p 1000 fps Slow Motion Videos

Sony has announced what it claims to be the first 3-layer stacked CMOS image sensor with DRAM for smartphones, which allows for fast data readout speeds making possible still images capture of fast moving objects with minimal focal plane distortion, and recording of Full HD (1920×1080) slow motion movies at 1000 fps, which compares to current solutions capable of only 720p @ 240 fps such as Google Pixel phones. Sony CMOS camera key specifications as listed in the press release: Effective pixel count – 5520 (H) x 3840 (V) 21.2 megapixels Image size Diagonal – 7.73mm (Type 1/2.3) Unit cell size – 1.22μm (H) x 1.22μm (V) Frame rate Still images – 30fps; 4:3 19.3 megapixels / 16:9 17.1 megapixels Movies – 60fps @ 4K (3840 x 2160); 240fps @ Full HD / 720p Image format – Bayer RAW Reading speed – 8.478 ms (4:3 19.3 megapixels) / 6.962 ms (16:9 […]

Older Intel Atom C2000 Series Server Chips May Stop Working After a While, and There’s no Fix

It takes time and efforts to debugging hardware and software to get a product right, but some bugs may be hard to reproduce, or only happen over time, and it appears some Intel Celeron C2000 series processor for microservers may stop working after about 18 months, with the likelihood of problems increasing over time, due to clock signals that stop functioning. This is documented in Intel Atom Processor C2000 Product Family Specification Update, with Errata AVR 54 explaining the issue: AVR54. System May Experience Inability to Boot or May Cease Operation Problem: The SoC LPC_CLKOUT0 and/or LPC_CLKOUT1 signals (Low Pin Count bus clock outputs) may stop functioning. Implication: If the LPC clock(s) stop functioning the system will no longer be able to boot. Workaround: A platform level change has been identified and may be implemented as a workaround for this erratum. Status: For the steppings affected, see Table 1, “Errata […]

How to Assign Brightness Keys in Ubuntu 16.04 and Greater

Yesterday, I installed Ubuntu 17.04 in CHUWI LapBook 14.1, and was surprised everything appeared to work properly. However, the laptop does not come with brightness up and down keys. So I looked for ways to assign other keys to adjust brightness on the laptop, and eventually found a solution on AskUbuntu, and tried the options for Ubuntu 16.04. First we need to install xdotool, a utility that simulate keyboard input and mouse activity:

Once it’s done, go to the Dash, start Keyboard settings app, select Shortcuts tab, and click on the + icon on the bottom of the window to bring up the “Custom Shortcut” window. Now fill the Name field with “Brightness Up”, and the Command field with:

Repeat the procedure with for the down key filling the Name field with “Brightness Down”, and the Command:

Now we should have our two brightness keys, and we […]

Installing Ubuntu 17.04 on CHUWI LapBook 14.1 Apollo Lake Laptop

[Update: The instructions below do not work with the newly manufactured models because CHUWI completely changed the hardware The company also disabled the Linux option in the BIOS (See comments in this post) So you may need to use rEFInd boot manager or isorepin.sh script to install Linux (and some drivers may still not work out of the box) ] Since I’ve completed the review of CHUWI LapBook 14.1 with Windows 10 last week-end, I’ve decided to give it a try with a Linux distribution, and I chose to go with a daily build of Ubuntu 17.04 since we’ve seen Apollo Lake platforms need a recent Linux kernel. While Ubuntu 17.04 will be officially release in April 2017, likely with Linux 4.10, the current (alpha) build comes with Linux 4.9. I had already quickly booted Ubuntu 17.04 on the Laptop from a USB drive flashed using Rufus right after the […]

Intel Atom x7-Z8700 (Cherry Trail) vs Intel Pentium N4200 (Apollo Lake) Benchmarks Comparison

Mini PCs based on Intel Apollo Lake processors have started selling, and they supposed to be upgrades to Braswell and Cherry Trail processor. I’ve recently had the chance to review Voyo VMac Mini mini PC powered by Intel Pentium N4200 quad core processor, that’s the fastest model of the Apollo Lake N series, and of course I ran some benchmarks, so I thought it would be interesting compare the results I got with an Atom x7-Z8700 “Cherry Trail” mini PC, namely Beelink BT7 which I reviewed last year. Both machines are actively cooled with a small fan, and storage performance is similar, albeit with a slight edge for the Apollo Lake SSD. A ratio greater than one (green) means the Apollo Lake processor is faster, and if it is lower than one (red) the Cherry Trail processor win. Benchmark Beelink BT7 Intel Atom x7-Z8700 @ 1.6 / 2.4 GHz (2W […]

Open Surgery Initiative Aims to Build DIY Surgical Robots

Medical equipments can be really expensive because of the R&D involved and resulting patents, low manufacturing volume, government regulations, and so on. Developed countries can normally afford those higher costs, but for many it may just be prohibitively expensive. The Open Surgery initiative aims to mitigate the costs by “investigating whether building DIY surgical robots, outside the scope of healthcare regulations, could plausibly provide an accessible alternative to the costly professional healthcare services worldwide”. The project is composed of member from the medical, software, hardware, and 3D printing communities, is not intended for (commercial) application, and currently serves only academic purposes. Commercial surgical robots can cost up to $2,000,000, but brings benefits like smaller incisions, reduced risks of complications and readmissions, and shorter hospital stays thanks to a faster recovery process. There have already been several attempts within the robotics community to come up with cheaper and more portable surgical […]

Oh Look… Espressif ESP32 Die-shot! That’s Pretty!

Espressif ESP32 was launched last year as a faster and upgraded version of ESP8266, with a dual core processor, 802.11 b/g/n WiFi and Bluetooth 4.0 LE. Boards based on the processor are still priced much higher than the ones based on ESP8266 ( although we’re only talking about $20 here), and shops have trouble keeping stocks, so either there’s a huge demand, there’s some manufacturing bottleneck, or maybe Espressif wants to take it slow at the beginning in case some hard to find bugs are found in the Silicon. Nevertheless, the guys at Zeptobar got hold of some ESP32 modules, and took some pretty die-shots. The die size is 2960×2850 µm. The prettiest part is clearly the RF section zoomed in below. If you wonder how it compares to ESP8266 die-shot, Zeptobar has you covered.
