CutiePi tablet gets a Raspberry Pi CM4 upgrade
CutiePi tablet was launched on Kickstarter last year with a Raspberry Pi Compute Module 3+ Lite, an open-source hardware carrier board, and an 8-inch multi-touch display with 1280×800 resolution. Shipping to backers is about to start, but the company has already started working on a new version of the CutiePi Tablet with the Raspberry Pi CM4 module released last October. This will enable greater performance and more memory with the tablet shipping with a 2GB RAM CM4 module by default. CutiePi CM4 tablet preliminary specifications: SoM – Raspberry Pi Compute Module 4 Lite with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 2GB RAM Storage – MicroSD card slot Display – 8-inch 5-point multi-touch IPS LCD with 1280×800 resolution Video Output – Micro HDMI Audio – 2W 8Ohm speaker, audio amplifier, built-in microphone Camera – 5MP front-facing camera (OV5647) Connectivity – Dual-band 802.11 b/g/n/ac WiFi 5 and Bluetooth 5.0 USB […]
Annke CZ400 AI security camera reviewed with basic and smart events
At the beginning of this month, I started the review of Annke CZ400 AI security camera by listing specifications, unboxing the device, and doing a partial teardown, notably to install a MicroSD card. In theory, the camera comes with more advanced AI features than Reolink RLC-810A 4K CCTV camera that only supports people and vehicle detection, as the Annke security camera can handle face detection, line crossing, unattended baggage detection, and other smart event detections. So let’s see how it performs Annke CZ400 installation The first challenge was the installation, as I told the company I would not be willing to install the camera on the ceiling since I’m renting, and preferred wall-mounting. after checking the user manual that included a wall mount, I decided to go ahead, and get the review unit. But sadly, the wall mount is not included in the package, and Annke even told me they […]
Windows Performance on an Intel NUC 11 Enthusiast Phantom Canyon NUC11PHKi7C
The Enthusiast Phantom Canyon is Intel’s flagship product from its latest NUC 11 range of mini PCs. Specifically targeting gamers it includes an NVIDIA RTX 2060 GPU. In this article, I take a brief look at the performance under Windows and compare it against Intel’s previous NUC with a discrete GPU: the NUC 9 Extreme Ghost Canyon. Hardware Overview The NUC11PHKi7C physically consists of a 221 x 142 x 42 mm (8.70 x 5.59 x 1.65 inches) rectangular plastic case which is remarkable because of its size and is similar to just a graphics card like NVIDIA’s GeForce RTX 2060 Founders Edition (229 x 113 x 35 mm). It is an actively cooled mini PC and uses Intel’s 10 nm Core i7-1165G7 Tiger Lake processor which is a quad-core 8-thread 2.80 GHz processor boosting to 4.70 GHz with Intel’s Iris Xe Graphics. But it also includes NVIDIA’s N18E-G1-B notebook graphics […]
