LTSpice Error Massage: time step too small
|
| |
Hello, I try to simulate a circuit, but I always get an error message: Analysys: time step too small; initial timepoint: trouble with u3:mm-instance m:u3:1 u3 is a Mosfet IRF4905. Has anyone an idea how I can solve the problem? Best regards. Sven

Various electronic stuff fo those interested
|
| |
Will pay reasonable shipping costs - but please ask only if you can use a given item set. 1) 6 sets ferrite cores P14/8/I-3C81-A400 (ie: gapped) and retaining clips. 2) Rather old, untested, Analog Devices 310J amplifier module 3L x 1.5W x 0.75H. 3) Misc old but good electrolytic caps, and various digital ICs.... more »

calculating saturation current of transformer
|
| |
I have designed a 1:1 transformer that will be used in a low voltage DC:DC converter. I have tested the current at which the transformer saturates by decreasing the frequency of the primary voltage while keeping the secondary open loop. I would like to calculate the theoretical value of the current at... more »

My daughter said the thumb drives wouldn't work on the computer ( Both work on another computer). This morning neither USB printer is working. So far the keyboard and mouse are working (both USB). Running XP SP 2. What could be wrong? Mike

Gustavo Duarte: [link] And hey, it's even on topic, as one or two articles briefly touch on multicore systems, and John will like this, bottom-up software design (he even references Feynman on design, can't beat that). Tim

Adapting a hi-fi's line-out to a computer's microphone input?
|
| |
I'd like to connect the line-level output from my hi-fi to a computer's microphone input (it doesn't have a line-in jack). Is anyone aware of a commercially available adapter for this purpose? Alternatively, what do I need to know to build one? Is a simple voltage-divider sufficient for this?
