We’ve written about Kendryte K210 RISC-V AI processor, and Sipeed M1 module several times including in our getting started for Maixduino and GroveAI HAT boards for low-power AI inference such as object recognition or face detection using Arduino and Micropython programming. Shenzhen-based Tinkergen, a STEM Education owned by Seeed Studio, has now leveraged the low-cost processor to design MARK AI robot kit, where MARK stands for Make A Robot Kit, in order to processor an educational AI Robotics platform for children ages 12 years old and more. MARK will ship as a kit with the main parts and components including a chassis, a cover, two wheels, stepper motors, a pan-tilt camera with K210 processor, a 2.4″ LCD display, Grove & Arduino compatible MARKduino interface board, some sensors, and six AA batteries. Tinkergen offers pre-trained model to recognized objects like humans, books, pens, or smartphones, as well as traffic signs, numbers […]
We live in a Sad World – Purism Anti-Interdiction Services are (Somewhat) Popular
A few years ago, we learned the NSA may intercept networking gear during shipping in order to modify it to provide backdoor access to the hardware, and it’s likely other national security agencies around the world also modify hardware on transit for spying purposes. I’d think most people would not really care, and only high-profile business and governmental targets may take preventive measures, but according to a recent post from Purism, their Anti-interdiction services are fairly popular among their customers. Wait… What? What is “anti-interdiction”. The only definition I know of is: “the action of prohibiting or forbidding something”. But it turns out there’s another definition that applies here: the action of intercepting and preventing the movement of a prohibited commodity or person. Purism laptops are not exactly prohibited, but you get the point, and the anti-interdiction services are meant, not to prevent, but detect interdiction of laptops or other […]
Swissbit Secure Boot for Raspberry Pi Relies on MicroSD Card and optional USB Stick
Swissbit secure boot solution for Raspberry Pi consists of an 8GB or 32GB “PS-45u DP” Micro SD card pre-loaded with their secure firmware, and offering the following key features: Security policies with flexible and configurable authentication Access protection with configurable retry counter Protects Raspberry Pi boot loader Encrypts user and boot code to protect license, know-how, and IP The boot image can be set read-only to prevent unauthorized modification Restricting the access to data on the card by various configurable security policies: PIN or USB or NET policy Use 8GB PU-50n DP USB stick as 2nd authentication for secure boot Works with Raspberry Pi 2 and 3B+ (I suppose Raspberry Pi 4 support should come soon enough) Note that we previously wrote about an open-source Raspberry Pi 4 UEFI+ACPI firmware to make the board SBBR-compliant and support features such as UEFI secure boot, but Swissbit secure boot is completely unrelated […]
