Self-hosted GLES on ChromeOS, part two

This is a follow-up post from an earlier guest post by Blu about OpenGL ES development on Chrome OS. One can’t practice real-time rendering to disk files for long ‒ it’s just unnatural. So after checking that my habitual GLES tests work as intended on ChromeOS when rendering to an off-screen-buffer-subsequently-saved-to-a-PNG, the next step was to figure out a way how to show frames on screen at a palpable framerate, if possible. Being as new to Chrome OS as the next guy, I had to start from scratch with ‘How to show EGL surfaces on screen fast’. In the comments section to the first article William Barath kindly mentioned that there was a wayland client library on Chromebrew, so I decided to pursue that as I had had (positive) prior experience with wayland. Long story short, the established way on most platforms for connecting wayland to EGL (or vice versa) […]

ARCO is a Real Robot that Lives in Virtual Worlds (Crowdfunding)

Hicat launched HICAT.Livera machine vision board for robotics projects on Kickstarter two year ago. The company second project is still related to robotics and machine vision, but geared towards a different target audience, as ARCO robot aims to offer an augmented reality gaming experience to kids, although it’s still hackable/customizable as we’ll see below. The hardware part is mostly comprised of ARCO ROVER robot, and a Bluetooth controller that can be stored in ARCO’s inner capsule, where it recharges and communicates with ARCO through a magnetic pogo connection joint. The listed specifications are rather limited: ARCO ROVER Bluetooth connectivity (nRF52 WiSoC) 10 RGB LEDs Battery – Good for about one hour Power Supply – Via USB type C port Dimensions – 8.9 x 7 x 6.5 cm Weight – ~180 grams Controller Bluetooth (nRF52) Sensor – 3-axis accelerometer for motion detection Trigger and rocker Battery – Good for about one […]

ASUS ZenBook Pro 14 UX480FD Laptop Replaces the Touchpad with a 5.5″ “ScreenPad” Display

Touchpads is a feature found in most laptops, but AFAIK there’s not been much innovation recently apart from maybe support for multitouch and gestures. But I’ve just found out ASUS started to showcase laptops without touchpad a few months ago, instead integrating what the company calls a ScreenPad, a 5.5″ touchscreen display placed at the location where you’d normally expect a touchpad. The company’s latest (and second) laptop with a ScreenPad is Asus ZenBook Pro 14 UX480FD, which comes with a 14″ display, processor up to an Intel Core i7-8565U Whiskey Lake-U processor, up to 16GB DDR4 RAM, and up to 1TB PCIe SSD storage, as well as an NVIDIA GeForce GTX 1050 Max-Q graphics, 802.11ac WiFi, Bluetooth 5.0, and more. You can visit the product page for the full specs, as I’ll focus a bit more on the ScreenPad in this post. The ScreenPad in this laptop is a […]

Seeed Studio Introduces 1 to 8 Channels Grove I2C Solid State Relay Modules

I’ve been playing with products or boards with AC relays for a while, but I never really cared to check about different types of relay. So far, all platforms I tested came with largish blue or black boxes which are SPDT electro-mechanical relays. But as I browsed through Seeed Studio, I found some weirdly-shaped relay modules, much thinner than usual, and fairly more expensive. The main difference is that those are solid state relays, and the boards also include a grove connector that allows microcontrollers or other boards to control the relay over a simple I2C connection. The modules are available in 1-channel, 2-channel, 4-channel, and 8-channel versions with the following specifications: MCU – STMicro STM32F030F4P6 Arm Cortex-M0 micro-controller Relay – Omron G3MC202P module Input Voltage – 4~6V (Rated Input Voltage: 5V) Load Voltage Range – 75 to 264 VAC 50/60 Hz Rated Load Voltage – 100 to 240 VAC 50/60 […]

Axiomtek SDM300S is an Intel Apollo Lake Smart Display Module (SDM-S) for Digital Signage

SDM300S Intel Smart Display Module (SDM)

Way back in 2010, Intel introduced the Open Pluggable Specification (OPS) defining mechanical and electrical parameters for players to be integrated into digital signage displays, with the goal of providing an easier upgrade path. Even if it was defined by Intel we’ve seem some Arm based OPS digital players such as the ones offered by ZidooLab. If you’ve checked out the latter link, you’ll know OPS players normally come with a case, and measure 180 x 119 x 30mm to comply with the specifications. But it turns out Intel also introduced a more compact card format for digital signage / displays with Intel SDM (Smart Display Module) available as SDM-S (Small: 60 mm x 100 mm x ~20 mm; up to ~10W TDP) or SDM-L (Large: 175 mm x 100 mm x ~20 mm; up to ~45W TDP) Axiomtek made one of those module with their SDM300S SDM-S module equipped with […]

PiMecha Humanoid Robot Based on Raspberry Pi Sells for about $500

SB Components introduced PiMecha humanoid robot powered by a Raspberry Pi Zero (W)/ A+ / 2 / 3 (B+) board, and offering 17 degrees of freedom (DoF) on Kickstarter a few months ago. But with KS backers expecting their rewards in September, the company is now taking pre-orders on their own website for the robot for 399 GBP, or about $511 at today’s exchange rate. The company has apparently not published any detailed specifications of the robot on their website. But the robot is basically comprised of an outer shell comprised of removable metal pieces, and precise smartbus servo motors. Your chosen Raspberry Pi board would be fitted to the robot’s chest together with PiMecha shield add-on board handling the servo control. PiMecha can be easily customized with a Pi camera, an LCD display, your own sensors an so on. SB Components provide software to program the robot in order […]

Kohler Novita “Therapy Bidet” Bluetooth LE Enabled Toilet Seat Works with Android & iOS Smartphones

If you’ve ever been to Japan, and to a lesser extend in Korea, you’ll probably have used one those toilet seat that sprays water, and ends with a gentle drying once you’re done with business. That’s all good, but you’d still need to press the buttons to activate it, and who knows what kind of germs may be on those buttons. But with Nordic Semi nRF52832 powered Kohler Novita “Therapy Bidet” (BD-TE80M) you don’t need to worry about third party germs, since it can be controlled over Bluetooth LE with your very own smartphone contaminated with your very own germs. The toilet seat bidet supports three different spray modes (active, silky, and mist) aka “water experiences”, as well as dual dry air blower combined with far infrared for “better skin care” and improved blood circulation. An auto-customization mode is available for ladies during the thing that normally happens every moon […]
