Good Electric Strikes are not cheap. Yes, you can buy one for 30 - 50 dollars but in the end, you might not like it. Remember here is definitely: You Get What You Paid For It. So think twice before you drop your bucks on some cheap imported crap!

I have done some more work today on the current amplifier and found that I did not have the input turned up to a high enough voltage to obtain the full 1A output, so I have now repeated the test and monitored the heat output from the amplifier. ...
IntroductionWhen making electromagnets, it is difficult to know for sure what kind of magnetic flux density has been achieved. This is because it depends a lot on practical construction factors, where on the electromagnet it is measured, and the core...
I haven't had much chance to work on the clamp table this week so it isn't quite complete, the majority of the time has been spend building and testing the current amplifier after the PCB had arrived. For the clamp table, I have cu...
Before building this device I have tried lots of different design but in every circuit there were some issues, either it was also a metal detector or detect human as AC voltage source. I even built a device using instrumentation amplifier, 2nd order...
After all the painting and finishing off the One String Electric Guitar has been finished. I re-installed the pickup and wired it directly into the headphones amplifier as this enabled me to create an untethered system that I could then plug d...
Once the final guitar body had been shaped it was time to paint it. I decided to follow a painting strategy of undercoat then top coat of spray paint. The undercoat was just a wood primer and undercoat combined, which I sanded down after the first c...
No wires, no batteries, no solar panels, no screws, no glue and no suction cups, but a Klingmagon Subspace Probe can scavenge power to operate and cling to a vertical window without supports.
I have been planning to build an outdoor digital thermome...
Having created the prototype one string electric guitar body and pickup I wanted to be able to hear the sounds it makes. I don't have a guitar amplifier so I decided to use an ordinary music amplifier instead but this needs a pre-amp to make it w...
As the prototype body for the one string electric guitar has been completed the next step is to make the pickup coil. I have previously made a 3D printed bobbin to wind the coil on so all I need now is to select the wire to be used and wind it. I hav...
I thought I would start the building of the guitar body with the pickup itself. As I have a magnet which I think is suitable I decided to 3D print a bobbin that fitted it to hold the winding coil. The magnet is 8 mm in diameter and 15 mm in length so...
I saw the Project14 monthly topic of Electromagnetism and thought about it for a bit and couldn't think of anything that I could do - there didn't seem anyway of involving mobile robots in this, so I had decided not to participate. Some time ...
Here is more a tutorial to make a battery i remember when i was young to have made one of this have a look at the link, it's not mine (wiki source) but i know how to make it! https://www.wikihow.com/Make-a-Homemade-Battery Here is shown how...
I was thinking after seeing the size of the Raspberry Pi Zero to how the measures will be the next two generations of desktop computers. I guess they will not be wider than a cigarette and you will come to the suppression of the USB ports and HDMI an...
Dear Element14,Mine more than a project is an idea on how to make work a modern computer with HDMI to a HDMI monitor or tv with a wirless connection, i know there is wirless for wifi router bluetooth for devices but noneuntil now have look inside the...
I use an electric door strike, on Smarthab, it is relay controlled via 24VAC from the room controller.
The room controller is a TI C3200 LaunchPad, this gives me ethernet access so there is no money wasted. The room controller talks to an external ke...
This project is turning into a product! Check out the dedicated website www.Core64.io for the latest information.
