- An airspeed sensor is recommended for optimal performance during transitions. GPS speed is imprecise if it's windy! I will add one to the build as soon as possible. - I'm still building this thing, so it can happen that I change things up, pictures...

PARTS-4 analog joystick sensors with board"pro micro" (ATmega 32U4 based micro controller, Arduino Leonardo compatible)wires and solder (it's good to use the single wires you can plug in to make it more forgiving)3mm nuts and boltsdouble sided...

When capturing solar images using narrow band H-alpha filters for prominences and chromosphere imaging, the sensor protection glass and anti-reflection glass of the camera can create reflections from the almost parallel light beam coming from the...

... for gantry leveling) and a z-endstop. Myself I use the inductive probe as a z-endstop also, however I chose a more precise inductive sensor than the official - the Omron TL-Q5MC2-Z. ... Check it here: https://s.click.aliexpress.com/e/_BfihOa5V

Parts required: - Six M3 hex nuts - Six M3 Bolts of at least 22mm length (can be longer), used for the belt holder - Three M3 Square nuts - Three M3 18mm bolts Other 3D prints used in this project include: - Mistral 2.1:...

For example, you'll need to figure out endstops on your own, as I'm using a Duet Wifi for sensor-less homing. There may be several other things you'll need to troubleshoot, but I wanted to share all the work I've done. The idler mount to idler...

The final product is ideal for a large CNC with a thick router cable, 3 limit switches, one NEMA 32, and 2 NEMA 24 stepper motors, with enough space left over for another thick cable and possibly the cables from another sensor or two. These cable...

You should drill a hole about 1 1/8" or 1 1/4" on the outside; this will be used for maintenance as well as the IDLER END SENSOR will exit through this hole. (PIC 1) The other hole is where the motor pole/gear goes in and out. This requires a...

You can even detect direction of rotation by using two detection sensors and comparing their outputs. This is exactly how old school trackball mice did their magic, and the method is still widely used today in a myriad of machines of all kinds. The...

The thin part of the ruler measures the distance between the reflecting face of the main reflector, and where the focus/sensor/microphone/speaker/lightbulb is supposed to be. Check "mockup" mode if you're unsure how the pieces are supposed to be...

These features include modified housing, which incorporates the dart chamber part into the main body, and dart sensors using IR technology for more precise movement. The current software has hardcoded this feature. To enhance user experience, I'll...

The newer kits have a cartridge sensor that is held by a set screw; make sure you get the K-type cartridge. ...* There are two files for the extruder holder, one is for aluminum extruders (alum_ext.stl) and one is for the factory MB extruders...

Note: Allegro has end-of-life'd this Hall-Effect sensor. As of this posting, DigiKey still has over 11,000 of them. But I don't know what Hall-Effect will be a suitable replacement should they run out. So you may want to check its availability first...

For the Bedini-style circuit, orientation doesn't matter much but if you plan to use it with a unipolar hall sensor as the switching mechanism then plan accordingly. After placing magnets apply superglue evenly over the face of the rotor and magnets...

Not only does it give the physical dimensions of the phones, it gives information about the zones around the cameras, sensors, buttons, and ports. I took that information and made a model of the iPhone 6s plus in OnShape, and then made the case...

UPDATE: We've received our new sensor, and I quickly drew up a holder for it to mount to the new hole in the left side instead of a cooling fan. I'm using a separate house fan and a lower bed temperature for layers after 2 – 45°C, which seems to...
