Hi Nigel. My impressions from trawling around is that the 1-2ma current will have a problem driving a FET.
Also, I can only supply a bias voltage of 3.3V, which may be too low for FETs.
Is that an incorrect assumption ?
EDIT :- Just realized there are logic-level MOSFETs. Would you advise on...
I have a pulse that is approx 5ma at 3.3V
This needs to drive a device that needs 50-100ma at 3.3V
I can supply 3.3V or 5A for operational voltage.
any idea what IC I could use for this ?
I know I can build a current gain circuit from a npn transistor, but I am hoping that a low power current...
Restarting thread
Hopefully some of the posters are still interested in this.
I put the project at the backend, then started it again recently.
Here is the description.

So, if C1, C2 ... Cn are cameras
and D1, D2, ... Dn are delay circuits
and Pulse denotes the ON trigger pulse (just...
The circuit is a 3.6V Lithium battery in series with a switch. This output is connected to 30 cameras in series..
The camera firmware recognizes a signal of 3V as a shutter release. Thus, when the switch is pressed, the circuit completes and a shutter release signal is registered..
I want...
Hi! I am connecting 30 devices in series. I am trying to delay the input pulse 4-10ms for each device. Thus Device 1 is 4ms delayed from Device 0, Device 2 is 8ms delayed from Device 0 etc.
Since the delay is small enough and does not have to be precise I am thinking of using a simple RC...
