    512k (64k x 8) nvram? (Resolved)

    Hi, I am looking for 512k(64k x 8) nvram, but can't seem to source it. Does anybody have a link, assuming it exists? I found SPI chips, but I can't find parallel sram as nvram. p.s. I have this: ds1230y 256k(32k x 8) nvram. Thanks, Kei

    Wiring 25 LEDs with a PWM Dimmer

    Not usually one for asking questions in forums, as I'm usually able to find solutions with my own research, however, I've been looking at this over a period of days now, and the deeper I dig, the more confused I'm getting.. I'm a Computer Science student, not electronics, so please go easy on me...

    Power supply turn off when latching solenoids switches ON?

    I have two 24VDC, 1.54A latching solenoids. I connected them both in parallel with power supply (80V, 80A). But when i turn ON the power supply it immediately turn off. However, when i connect a single latching solenoid with power supply it works fine. Is it necessary to use two power supplies...

    Parallel Inverting Summing Amplifiers

    Hello Everyone, To add on to my newbness from yesterday, I have one other part of my design that I am not sure what's going on. I have some suspicions but thought you guys probably could spot it pretty quickly or at least probe at me to look at it differently. I have again attached a setup...

    DC Motor in parallel with a Voice Recorder Playback Module

    I’ve build a circuit using 3V(2x 1.5Volts AA battery)connected in parallel with a ISD1820 Voice Recorder Playback Module with Speaker in parallel with a DC Motor and a Red Led. When I turn the circuit on the LED brightness reduces and the recorded audio in the speaker doesn’t play. What should I...

    Current dependant load switch, cant solve it passively?

    Hey there, i couldn’t fall asleep trying to solve following scenario: i have two power supplies running 24vdc in parallel, a main and one supplemental power supply. Both are being filtered with capacitors before supplying a single load. Now if one wants to run it, such that the supplemental...

    Using MOSFETs to control resistive loads

    Hello everybody! I want to dump energy from some solar panels into heating by using two heating elements (R1 and R2). To maximize the power output from the solar panels I plan to use a microcontroller to change between single heater, series and parallel configurations. Now, I tried to come up...
