Can a household manage on just 50 amps?
Today’s typical home is wired for at least 100-amp service, and many are wired for twice that number. This makes sense given the multiplicity of modern appliances and electronics in a home. The demand is obviously higher if you have an electric…
Canadian tech accelerator engages Nokia in quantum telecom testbed
After quantum computing, quantum communication is now stealing the headlines. Numana, a Montreal, Québec-based non-profit technology accelerator, has engaged Nokia and Honeywell Aerospace Technologies in its Kirq Quantum Communication Testbed…
Will compute continue scaling in AI clusters?
With the emergence of smaller models and techniques like distillation, will AI scaling stop, and we won’t need more compute power? Richard Ho, head of hardware at OpenAI, firmly believes that AI scaling will continue, and compute power will…
EcoFlow’s Delta 2: Abundant Stored Energy (and Charging Options) for You
As I briefly noted back in mid-November, I ended up replacing my initial failed-experiment lithium battery-based portable power unit, Energizer’s PowerSource Pro Battery Generator:
with two EcoFlow successors, the smaller RIVER 2:
and this…
Sensor aids EV thermal management
The first in a new line of immersion temperature sensors, the B58101A0851A000 from TDK is designed specifically for EV powertrain cooling. Compact and lightweight (<11 g), this fully sealed NTC thermistor provides fast, precise temperature…
Hall elements detect small magnetic fields
High-sensitivity InSb Hall elements from Diodes detect rotation speed and current across a broad range of applications, even in weak magnetic fields. The AHE300 sensor supports Hall output voltage (VH) classifications C through G, ranging from…
Reference design drives servo motors
ST’s EVLSERVO1, a turnkey reference platform for servo motor control, enables sensorless or sensored field-oriented control (FOC) with one, two, or three shunts. It drives three-phase brushless motors up to 2 kW with the provided heatsink…
BLE SoC meets automotive requirements
The Renesas DA14533 Bluetooth LE SoC offers power management features to reduce power consumption in automotive systems. AEC-Q100 Grade 2 qualified, it operates from -40°C to +105°C and is suitable for applications such as tire pressure monitoring,…
Test receivers boost EMI range and compliance
R&S has expanded its EPL series of test receivers to cover EMI measurements from 5 kHz to 7.125 GHz, offering flexible configuration options. Depending on the setup, these receivers can be used in development, certification preparation,…
Time domain reflectometry
In this look at transmission line theory, we will assume an RG-58 type of coaxial cable which has a characteristic impedance of 50 Ω. Where we let C stand for the capacitance per unit length, 30 pF per foot in this case, the characteristic…
A closer look at PCIe 6.0 interoperability, performance testing
PCIe, the most successful interconnect technology for more than 25 years, is entering a new phase of complexity with the adoption of PCIe 6.0, which is now largely driving artificial intelligence (AI) workloads. Gary Hilson talks to senior managers…
PWM-programmed LM317 constant current source
LM317 fans will recognize Figure 1 as the traditional LM317 constant current source topology. It closely regulates Iout = Vadj/Rs by forcing the OUTPUT pin to be Vadj = 1.25 V positive relative to the ADJ pin. Thus, Iout = Vadj/Rs to a very…
