I solder the tin between two Arduino circuits with hc-sr04 through their GND pin. As in the picture, red circle. The circuit will be fixed firmly !Try putting it in the box, there's still a good gap for the rest.Use glue to bond vibrating motor with...
So if you want to build this project for an industrial application, you should build an electrical panel for it. I won't go for a step-by-step tutorial on how to build that, because that's a whole book to read. but anyway let's do it, if your an...
Now it's time to solder the LED (or more accurate a Chip-on-Board, I will refer to it as COB).At first, take the adhesive glue and glue the COB onto the heat spreader at the position you have marked earlier. Wait some time (an hour or more) for the glue...
After some failed tries with pre-built Coaxial Power Connectors from China, I decided to go for Molex-connectors known from computer power supplies. Please be careful: most Y-cables you can buy on Ebay are not made for the high current we are using -...
Assemble the rubber mat, 12VDC electric motor and spay paint to complete. Test operation by running the machine continuously for 2 hours. And finally here is the result after running the test.
Now you can go ahead and build this. Just a few things to keep in mind: This might work with other dials with a ton of hacking, but the one I built this for is the older style Automatic Electric type 24 dial. I'm not among the surprisingly...
In a LED, the longer pin is the positive pole, and the shorter pin is the negative pole. So, we connect the shorter pin to GND and connect the longer pin to D13. Additionally, to avoid the electric current exceeds the tolerance of the LED and causes...
First I made the electric contacts for the headphones. For that I used copper tape. First I applied it on the top; then I did several cuts, spaced 1 centimeter each, and bent them to form an electrode in the lateral. It doesn't touch my head because...
Now, you have yourself a tiny USB stick form factor web server ready to use! This little web server use less than 2W. You will never notice a different in your electric bill even if you plug it into your wall adapter and running 24/7. So have fun hosting...
Let's ask yourself that how much power you want solar system will cover your electric bill each month. For example, each month your home consumes 560kWh, now you want solar system can produce electricity with amount 80% of that 560kWh. Then, solar system...
The supplies you need are pretty simple, and my hope is anyone can do this at home! Materials Old, discarded masksLet sit for 2 weeks, or dunk in alcohol because they might be grossLaser Cutting Files (Samples attached) Tools Heat SourceI used an electric...
Put something heavy on top of your plastic parchment paper sandwich and let it melt. It should be all melted well in about 5 minutes. Wikipedia says Polypropylene melts at 130 to 171 °C (266 to 340 °F; 403 to 444 K), and I actually set my skillet...
