Re: LED Flasher circuit why won't it work
It is not a "good" oscillator, in the sense that it does not guarantee that it works. If I understand it correctly, it depends on the zener-like reverse breakdown of the transistor's base-emitter

LED Flasher circuit why won't it work
Hi there, I have a circuit for an LED Flasher unit. I have reworked it about 3 times, but it still won't work. Could someone advise me whether it's the circuit itself is faulty or there another reason

Re: 555 as a MOSFET driver
I believe that based on the specs that he mentioned in some of those videos that it was indeed a TO-220 cased device He also did a couple of other videos, one on assorted MOSFET drivers and one on

avoiding compression in HMC8193 mixer upconverting mode
Hello,I have HMC8193 component where i need to use it for upconversion. IF=5dBm 500MHz LO=18dBm , 6GHz , What are the values of LO IF powers which could cause RF output to be compressed in P1dB?

Re: 555 as a MOSFET driver
For all ICs, one should look at the output drive capability. Then look at the load being driven. If it is a small MOSFET with low input gate capacitance, one can drive directly. However, if using a

555 as a MOSFET driver
I've seen all sorts of specialized chips, or piles of discrete components used to get optimal drive for MOSFETs, but happened to stumble across this video: https://www.youtube.com/watch?v=FKqkRDM0Al0

Re: Ancel battery tester
That was interesting, but a configuration for what? That *.exe file? What I need is to find out what this hardware does, not their software. (snip) There ain't enough force to make that happen here...

Re: Ancel battery tester
Don't know anybody that does that. Ain't gonna happen. This machine running two versions of linux, one in a virtual machine where I do my emails, that would be way too complicated. No such thing. Yup.

Ancel battery tester
So I have this battery tester, which was discussed in here not all that long ago. One of the menu options is to print the results, which I'm assuming is stored in some kind of flash memory or similar.

The control system may be a little more complicated that what you envision.? Many feedback control systems utilize a rate encoder rather than position.? Older ones output a voltage that is

methods reducing |VGS| of a mosfet question
Hello,As you can see below M1 Vgs is 14V. I dont need 14V to open this transistor , I need only 5V. I have extra Vgs, Is there a way to reduce the Vgs? Thanks.

Re: Help with Amada 103 hidraulic brake press. Servo drivers - DC motor with encoder - Feedback LOOP - hctl-1100 - mc1408 - rc4136
Why not start by swapping boards to see which portion of the drive signal is causing the offset. Hopefully the this drive is distributed on multiple boards. Dan

Good night everyone ! I have a problem with the Y-axe DC motor on an hidraulic press. Sometimes it tend to slowly move clockwise when its suposed to stay still. I have measured 0.4 v on the motor
