I am using a Triac dimmer for dimming an LED (dimmable) lamp. The zero-cross detector is from a simple transistor on the secondary of the transformer (before smoothing). All works fine except that the LED flickers a bit in the low range. Analyzing on the scope the zero-cross pulses vary in the...
I have disigned a dimmer circuit using Pic12F629. It works fine but with a little electrical noise the pic is resetting. I have added L1 and L2 inductors (see circuit) and some capacitors across the supply but did not solve it completely.
Any idea how to make Pic completely immune to mains...
I am designing an H bridge using the FDMS7556S mosfet.
The datasheet states - "This device has the added benefit of an efficient monolithic Shottky body diode."
Does this mean that I can omit the catch diodes?
I've been looking for (cheap) outdoor ultrasonic sensors but could not find any assembled in a module (except Maxbotix which are out of budget).
So I am thinking if changing the transducers on the SR04 module to waterproof type might work. Any feedback is welcome.
My application is for a trip...
I just bought this connector
***p://www.ebay.co.uk/itm/191278895319?tfrom=191405132575&tpos=unknow&ttype=price&talgo=origal
It says 30A rated but on arrival I found the contacts to be only 1mm diameter which I really doubt they can handle 30A.
So can someone point me to a similar connector...
I was seeing Discovery channel and they featured an electric motor bike that can stay standing by itself.
This was a normal 2 wheel bike so I cannot figure out how it is possible to stay standing up by just actuating the motors.
Any idea on the principle used?
I have a simple circuit for controlling the speed of a 12V 10A dc motor using 1 mosfet on the low side. For cost reduction I opted for no heatsink and chose a mosfet with the lowest RDSon. This worked well with no much heating.
However I am getting a lot of heat in the flyback diode. I tested...
Hi I am an electronics engineer and just subscribed to this forum. Its very informative - keep it up.
I have a project for building an ROV. Maximum depth is around 400m but I'm planning to use a cable of 500m for drag compenstion. My idea is to use IP camera on the ROV and send the commands via...
