...There was a mechanical relay on it but I changed it with a PNP mosfet. Because the car relay draws only 500ma of current, any mosfet that can handle 3-5A is enough. I have used IRF4905 lying around. You can see the PNP mosfet connection in pictures.

My finger and thumb got multiple very shallow slices in them before I even realised what was happening (so maybe wear a kitchen rubber glove to install or remove the caseless objective, lol).This objective has a nominal aperture of f/4, which is an...

The learning mechanism would be possible only with a feedback method, like the ultrasonic or infrared sensor. For the power consumption a Hall effect current sensor could be fine.</p><h5>Sinusoidal</h5><p>The only sequence I tested is a sinusoidal...

Personally I find the best, tight, results when gluing together in the closed position.After getting the G compartment, cut off any excess belt material.If some sort of mechanical fixture is desired for reinforcement, there are two options.For bolts,...

Secondly, it can be used with other controllers as well ... I installed the drivers TMC 2208, with them the movements are silent. In terms of mechanics, there was also one change, seemingly a trifle, and nevertheless it is very important. The...

Finally, tighten the screw. OK, if all mechanics are working as expected, your useless machine should work as expected. You can now close the housing, using the last 5 M3*10 screws.</p> <h3>What does it do?</h3> <p>Basically, the Arduino will cycle...

So the weed whacker attachment can be programmed to make a path through the garden box at a height slightly lower than the gantry to ensure that no plants cause mechanical failures. Information on water input (mount vs low pressure flow) Watering...

I was attracted to the Deltabot design due to its symmetry and mechanical simplicity. A light weight, fast print head and a stationary build platform. Fortunately the more complicated software side has already been taken care of with many options...

after mechanical polishing clean the parts, prepare wet cloth; 2. heat the surface with the heat gun or small torch until surface gleams (you can see bubbles if overheated); 3. gently run the wet cloth over the surface to smooth and cool it (move...

...This may harm the mechanical parts of your printer or the micro switch box or at least the levelings. So, before Auto Home, manually turn the Z axis lead screw (or coupler) with your fingers to left to decrease Z level a few cantimeters (ie 1-2cms).

Isaac Clarke 3D model, the main protagonist of the video game franchise, can now be replicated with the help of 3D printing. The shooter video game shows the main character, a ship systems engineer, show his struggling overcoming dementia and...

Despite it’s freakish looks the folding lever pump mechanism can - with reinforced internals - still prime heavy spring loads; with the max load I’ve tested (read: max I was able to fit inside the sledgefire) being 17 coils of pro-26. This mod isn’t...

It can, therefore, be officially used as a protection against mechanical impact. We state that the purpose of the use is to provide the wearer with frontal protection against flying drops. <strong>Unfortunately, every manufacturer has to go through...

The biggest changes are:Improved mechanism for opening the emitter. It opens up by pressing the blue switch on the side, just as it does on screen. To close it, push the switch on the other side.</li><li>Addition of a plasma ring around the...

The digestive process involves the mechanical breakdown of food, followed by the chemical digestion of nutrients. The human endocrine system is a network of glands that produce and secrete hormones into the bloodstream. These hormones play a crucial...

After working with Mech, and tweaking the design fully to ensure optimal specs this is the end product. - Multiple models will be released this being the first of them. Please read everything so I don't have to address stupidity or lack of anyone's...

... and takes care of summer and winter time adjustments. I plan to add a date display, Pizza timer, Alarm clock, door bell visualizer and other stuff, too. The source code will be released here, once everything is in place and somewhat cleaned. ...

This slot serves for placing the lock (next step).The label tag is important because it secures the cover (prevents the cantilever snap joint to easily release).. ...but the label with time can slide, therefore the next step is important.</p><h5>Locking...

Since initially publishing this kit, I’ve subsequently released dozens of additional parts kit, intended to be fully compatible with this one. See my Cults3d Profile for a full list. Project goals On a personal level my goal was to learn the basics...

&nbsp;3 M3x16mm cap head screws clamp the assembly together, when everything is in the correct place the blade will be held in exactly the right position, and can easily be swapped out for a fresh blade by loosening the screws and releasing the...

Fishing wire should support the weight pretty easily but it likes to snap when rubbing against the threads of the tension block screw so it can help to lift the speaker first, adjust tension, then release the woofer in order to minimize this. TIP:...

In contrast to the BFPTouch, this thingy uses a nano sized linear servo to release / lock the flag, thus it doesn't need as much space as a micro servo. BOM To build the Tiny-Touch you'll need: * 1 x 5V linear nano servo like the Graupner...
