In telecommunications, ideal RF switches require low insertion loss, high isolation and linearity. The IDT F2912 is a single-pole-double throw RF switch capable of having low insertion of loss of 0.4dB at 1GHz and a RF1 to RF2 Isolation of 74dB at 1GHz with extended temperature of...

An update on LuckyResistor’s data logger project: Just to let you know the deluxe version of the data logger is almost done. The hardware is ready and tested – currently I finish the menu based software for the data logger. Menu based control with 5 capacitive inputs Record,...

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...

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)...

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...

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...

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...

by Marcus Jenkins: This gadget steps up the game from leaving a light on at home when you’re out. Place it near a window to make it look like somebody’s at home watching TV. The idea of leaving a light on at home while you’re out is to give the burglar an uneasy feeling that...
