Good bye,
I wanted to build my own (adjustable) table and am stuck on an electrical/mechanical problem. I'd like to have the table raise and lower from a certain height at the push of a button. Is there a DC motor that I can use to set the end positions from 50cm to 100cm?
PS: I got an adjustable table a long time ago and wanted to use the motor, but it can go higher and has no end positions.
Thanks in advance, have a nice day! 🙂

Hello, I'm looking for a cigarette lighter with a USB port without an LED. It shouldn't draw any power when the ignition is off, because my cigarette lighter socket draws constant power. Unfortunately, I can only find ones with LEDs online or in electronics stores. Do you know where I can find ones without LEDs?…
Hello everyone, I have a Telefunken TV that constantly changes the picture quality. That's not a problem in itself, but when you're watching a movie and the screen always goes black after two minutes because the TV is changing the frame rate, it's really annoying. The problem is that I always have to go to…
I was just wondering if an ultrasonic sensor or radar sensor could theoretically detect a weapon shot approaching the sensor quickly enough to trigger an evasive maneuver, for example, in an autonomous drone? Would that be feasible?
Hey, It would be about directing an incoming laser beam, no matter where it hits, onto a photoresistor located in the middle of a field of about 3x3cm! Preferably without a mirror or inexpensive. Can anyone help me with how I can implement this?
If it is to be in certain areas, you can either use computer-controlled stepping motors or end stops that operate a contact.
Upper and lower start-up maximums can be implemented mechanically and electronically in a simple relay circuit by end-position probes. In contrast to overload in the mechanical adjustability stop, it is then easy to insert additional fuses into the load current path of the motor if it is too difficult to act against the adjustability stops, and thus the current load in the motor circuit does not project too far in blockage.
As far as safe-simpel in Russian style in minimalism.

Servus, my problem is: I don’t know where to place the whole thing. Have rebuilt the table of FlexiSpot E1, please watch on the net once. The motor is centrally placed and connected to a hexagonal rod with both feet, where should I attach microswitches, relay circuit, end position sensor, etc.?
Sorry, I’m out of the search for specific online bastelan lines.
In general, however, I would then attach two strips to the end position determination at the lifting frame parallel thereto. A bar is fixedly connected to the movable lifting deck and houses the mechanical triggers for the end position probes.
The other rail mechanically picks up the end position probes and is fixedly connected to the immovable base frame of the table.
The motor itself should not care if, for example, you would have attached it to the central axis of the threaded or gear linkage of a height-adjustable MuFuTi or the like already at that time instead of the otherwise usual hand crank.
However, place your end position switches more easily so that they already switch off the mechanically actually possible end position at the top and bottom, so that the fuses in the motor circuit really only with switch failure or mechanical end position overload, or Table overload is likely to appeal.
… use microswitches or read contacts for OT unf UT.
