Jubilee Hills: Alzheimer’s disease can be tough on caregivers, especially when difficult behaviours like aggression or wandering occur. Alzheimer’s is the most common cause of dementia, a general term for memory loss and other cognitive abilities serious enough to interfere with daily life. Caregivers of Alzheimer’s patients may find their loved ones acting in unfamiliar, […]
I’m a fan of all kind of weather stations. When Daniel Eichhorn twittered about his new version using an E-Paper display module, I immediately preordered one. I decided to build a station with a custom enclosure, so here is my version of a 3D printed version, featuring magnets so it can be attached to the
The Doppler Effect I’m sure you’re quite familiar with the Doppler effect: you send an RF signal at a given frequency to a target, and if this object/person is moving the reflected signal’s frequency will be shifted. This is the reason why a fire truck’s siren has a higher pitch when the truck is going

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, which is decidedly more off-road than America’s Power Racing Series. In pushing these little electric vehicles to the limits, many builders

WiFi 5 also known as 802.11ac has been around for a while now, but few boards have adopted it. The WiFi 5 might easily be confused with the general WiFi (802.11 b/g/n). The WiFi standard 802.11ac is capable of 1300 megabits per second (Mbps) which is the equivalent of 162.5 megabytes per second (MBps), this is 3x faster than

Arduino MKRFOX1200 has been designed to offer a practical and cost effective solution for makers seeking to add SigFox connectivity to their projects with minimal previous experience in networking. It is based on the Microchip SAMD21 and a ATA8520 SigFox module. Long Battery Life Can run for over six months on 2 AA 1.5V batteries
It might not be the kind of thing you’ve given much thought to, but if you’ve ever used a desktop 3D printer, it was almost certainly being controlled by an 8-bit CPU. In fact, the common RAMPS controller is essentially just a motor driver shield for the Arduino Mega. Surely we can do a bit
Qualcomm announced back in April its QCS605 SoC, calling it “the first 10nm FinFET fabricated SoC, built for the Internet of Things.” The octa-core Arm SoC is available in an Intrinsyc Open-Q 605 SBC with full development kit, including a 12V power supply which is available for pre-order at $429. The product will ship in

It used to be that there wasn’t a problem on the average car that couldn’t be solved with a nice set of wrenches, a case of beer, and a long weekend. But the modern automobile has more in common with a spaceship than those vintage rides of yesteryear. Bristling with sensors and electronics, we’re at

Seeed has launched a $24.50 “Grove AI HAT” with 6x Grove interfaces and Arduino IDE support for accelerating edge AI workloads on the Raspberry Pi. The HAT features a Sipeed MAix M1 module running a Kendryte K210 RISC-V neural processing chip. Neural acceleration chips seem to be everywhere these days — built into SoCs such
Latest Grove add-on for the Pi includes RISC-V NPU for edge AI duty Continue Reading
