Noobie Question!
I just got a UV lamp I need for Uv glue curing but the plug is European, I live in Mexico and I dont know if I have to return the lamp or an adaptor will do the trick
I’ll put the link where I bought the product, some specifications and photos.
I dont know enough electronics...
Hello, Im trying to make a UV lamp to cure UV resin, because of the price of other systems I decided to buy my own UV 9W electric bulbs to wire them up.
Now the issue Im running into is that no matter what I do they are not turning on.
I want to hook them up directly (no circuits, only with...
I have a light mounted underneath my desk to illuminate equipment there. It has a touch-sensitive switch which is always turning on when I brush it with my knee, which is very annoying. I opened it up, hoping to disconnect the switch, and connect a simple toggle switch to the leads, and mount...
Nowadays home automation is a trending topic among electronic enthusiasts and even the mass population. People are busy with their life challenges, so an electronic device should take care of the home instead! The majority of such devices need internet or Wi-Fi for connectivity or they don’t...
I bought a USB desk lamp. It has a power switch + 2 switches to increase/decrease brightness. But these buttons are hard to press, very slow to operate, and even the darkest setting is still very bright.
I'd love to add a true dimmer switch, so I can quickly turn it on and set the brightness in...
The best ever bicycle lights from the 1980's and very commonly part of my 90's childhood. I use them on my bike. I managed to source one from ebay which was opened/barely used but sadly water/moisture had rusted away one of the battery terminals which crumbled, I intend to make a new terminal...
My view on life, in any field, is not to produce more but to consume less. Everybody told me this is a very eccentric weird mentality. Perhaps they are right. Nevertheless I have to build my project to make a highly efficient, extremely low drain, motion triggered 12V battery powered dimmable...
One Bit Switcher
I offer my own version of the circuit of the switch 12v. led-lighting for the kitchen based on the dual trigger of the hc74 chip.
Created with EasyEDA.
Hi everyone,
this is my first post here, hope my thread will captive you :)
I m a beginner in electronic stuff and use to be "one day" a JAVA developper :p
I'm working on a small robot gadget i try to teach about distance and color.
I want a "base", placed in position A, this position is...
My old car uses a 1mA current driven tach movement and the stock circuit isn't compatible with the MSD ignition box I use, and the adapter they sell to make the tach work buzzes like the dickens.
So I worked up a tach circuit based on the current tach diagrams in the LM2907 datasheet that'll...
Hello everybody!
I own a little beverage store and as an advertisement I hung a 12-pack (4X3 bottles) of emptied PET water bottles with a price tag (above the water pack) from my fence on a rod near the road. It moves a bit in the wind and gained some attention. To make it more attractive I'd...
Hello
I am thinking of building the below circuit but i am short on components. I have all the others except SL100 transistor and BT44 triac which i can't seem to find in any local store. If anyone can tell me what alternative components i can use for these two then please let me know i would...
