by Graham Prophet: LT8330 is a current mode, 2 MHz step-up DC/DC converter with an internal 1A, 60V switch. It operates from an input voltage range of 3V to 40V, making it suitable for applications with input sources ranging from a single-cell Li-Ion to automotive inputs. The device can be configured as either a boost, […]
Freeze 75 – and you have a temperature under control
https://www.electronics-lab.com/freeze-75-and-you-have-a-temperature-under-control/
Freeze 75 spray will enable you to find faulty component or also to protect components from overheating during soldering. A device operates OK until it reaches stable operating temperature … a typical situation in praxis usually caused by a faulty component or faulty (cold) joint. Localization of such a fault is easy only if we […]
Measure small currents without adding resistive insertion loss
https://www.electronics-lab.com/measure-small-currents-without-adding-resistive-insertion-loss/
by Maciej Kokot @ edn.com: In most cases, you measure current by converting it into a proportional voltage and then measuring the voltage. Figure 1 shows two typical methods of making the conversion. In one method, you insert a probing resistor, RP, in series with the current path and use differential amplifier IC1 to measure the resulting […]

This reference design is a frequency generator for use in synchronizing a circuit’s operation. It consumes less than 50mW of power that specifically uses the IDT’s 9FGV0241 PCI-Express Clock Generator which is the lowest-power PCI Express timing family. It is a two output clock generator with programmable output amplitude allowing tuning for various application environments. […]
A Connected Lamp to Wake Me Up
https://www.electronics-lab.com/a-connected-lamp-to-wake-me-up/
Limpkin has modified his IKEA lamp to use 10W LEDs. So for some reason I bought 2 IKEA lamps at a flea market. As IKEA furniture has a long history of being hacker-friendly, I figured they shouldn’t be an exception to the rule. My plan? Fit a few 10W RGB LEDs in there together with […]
