This project uses IR sensors to detect when a ball is near then triggers a relay switch to the external power source letting current through the wire which pulls the ball away from the sensor and to the next magnet. No programming at all.
I broke my Harbor Freight bug zapper so I decided to turn it into an EMP Device. A 3D printed coil support, some 18 Gauge wire, and Hot Glue is all it takes to make a DIY EMP Generator.…
Using teacher-provided dimensions, students design and model coil frames suitable for 3d printing. The students then wind the coils and observe the function and characteristics of the electromagnet
Update April 5, 2024: I just published two holders for this tool. Either holder can be used on the Honeycomb Storage Wall by @RostaP or on any flat surface. Check out HSW Mechanical Electromagnet Holders at…
The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields. This diagram shows a plane linearly polarized EMR wave propagating from…
Part list: 12mm metal ball 4 Mosfet Transistors Insulated copper wire 4 infrared emmiter 4 infrared sensors 4 inverter * 5V 2A power supply Some resistors * I used the 74HC02E and connected the two inputs together and therefore converted…
Don't you love it? Magnetism? Electronics? And 3d printing? In this project I combine all of them together to a little but spectacular do-it-yourself experiment. With just a few components and the 3d printed part you will be able to build…
Ideally, turn the winding tool on a lathe. Stick it through the spool and mount it in an electric drill or similar, then wind your wire onto the spool.
Update 2022-09-19: There was an error in previous versions, please use _v4 FreeCAD file for your own experiments. fischertechnik compatible housing for a 10x10mm electromagnet from aliexpress ("10*10mm Suction 0.3KG DC 5V/12V/24V Mini…
Electro Magnetic Gimbal modification, could be a Galvo XY laser mirror base, or something else - please experiment, remix, comment and post makes! as it is it configured (untested) it should hold one 10m diameter magnet of up to 5mm…
A hands-on teaching model demonstrating electromagnetic induction. Students rotate permanent magnets past a coil and observe the induced voltage and LED response.
Stencil per disegnare sempicemente le linee di propagazione del Campo elettromagnetico lungo una direzione. Dimensioni 35 mm x 56 mm x 1 mm. Buono studio e buon lavoro!
This project can be used as help material to make more easier to learn how electromagnetic induction works. I appreciate the feedback! Layer height: 0.2 Infill density: 30%
I love the Honeycomb Storage Wall by @RostaP enough to now have a 30-panel wall in my workroom - covering 108cm x 111cm (nearly 4 feet x 4 feet)! All of the outer panels have a solid frame thanks to the fabulous Honeycomb storage wall…
This project is a 3D-printable assembly for a Linear Induction Accelerator. It serves as a practical experiment for students and hobbyists to understand how magnetic fields can interact with metallic objects to create motion. Educational…
Equation of electromagnetic propagation power given a distance between the transmission and reception power Category: Keychains
This is a outline of electromagnet
This model allows replacing the original gripper of the PyBot SCARA robot with an electromagnet that allows picking and placing metal objects. The associated end stop triggers when the electromagnet is in contact with the object to move…
The plugs for the bolt holes will be adjusted Print Settings Printer Brand: Creality Printer: Ender 3 V2 Rafts: No Supports: NO Resolution: 0.2 Infill: 40 Filament: PETG, PLA (with black lack)
Add neodymium magnets to spin in the holes, and can connect to lego axle.
Over engineered mounting solution for mounting electromagnet coils to 8020 railing. Additionally features vents as well as cutouts for mounting a 20x20 mm fan for active cooling. Cut outs are made for standards m2 4mm threaded inserts .…
This is a cover that fits over the back of an electromagnet assembly salvaged from a Gardner Bender GMT-312 Analog Multimeter. Keeps dust out. After printing, you will need to drill out two small holes matching the electromagnet…
Top mounting plate that mounts directly to the electromagnet mounting bracket. Additional cutout made for a hall effect sensor module while maintaing 8020 T slot railing compatibility. Either componant can be used as a stand alone for…
A replacement spool for an electromagnetic coil label 184037. Printed in Nylon GF (hopefully for heat resistance and durability). Glue the two pieces together. Spacer is for mounting on a spinning shaft to quickly wrap wire around the coil.
Summary It’s an electromagnetic seesaw! This is a piece of lab equipment designed to measure the force of an electromagnet on a lab scale, and includes the seesaw itself, the seesaw stand, and an arm to attach the core of your…
Single Stage Electromagnetic Coilgun In this project, I built a single stage electromagnetic coilgun capable of launching a bearing steel projectile to a height of 10.7 meters at an initial velocity of 14.5 m/s. This was built as a…
Warning, before you test this device make sure that you protect your sound card from voltage spikes or use a disposable device. Use thin copper wire to make coils and connect it to a sound card that supports stereo recording. In Audacity…
# MagLev Electromagnet Levitator for Arduino A desk-top magnetic levitation stand. A permanent magnet on top of a hand-wound coil pulls a small neodymium "floater" upwards; a linear Hall sensor under the coil watches the floater, and an…
