If you're connecting shafts of two different sizes or even two of the same, you'll need a coupler to join them. be sure to pay attention to the Imperial vs. Metric sizes.
This is a small selection of our maker favorites, if you're after more options, check out our full range of Couplers and Collars.
Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be...
We've got different configurations of gearboxes to suit any project, however, bear in mind that these are plastic gear boxes, perfect for high speed, low torque, but for high torque applications where a lot of strain is being placed on the gears, you'd be better off with a metal gear motor.
Tamiya’s double gearbox packs two independent gear trains into a compact and affordable package that is great for small mobile robots. Each side can be assembled to have one of four gear ratios: 12.7:1, 38:1, 115:1, or 344:1.
The single gearbox is perfect if you like the gear ratio options of the 70168 double gearbox but need just one motor or added flexibility in positioning multiple output shafts. Available gear ratios are: 12.7:1, 38:1, 115:1, or 344:1.
Tamiya’s twin-motor gearbox consists of two independent brushed DC motors and gearboxes in one compact housing, making it perfect for small robots. You can assemble the gearboxes to have a 58:1 or a 204:1 gear ratio.
These clear nylon screws and nuts can be used to fix your circuit board, sensors and mechanical mountings. Used in applications where moderate strength, electrical insulation, and great resistance to corrosion are required.
Standoffs are useful for mounting circuit boards, hardware, and anything that has holes for standard screw sizes. Be sure to choose nylon if they'll make contact with electrically sensitive components.
Suitable for all kinds of circuit boards, sensors, mechanical support of the installation. They are great for building a multi-level robot chassis. This 10-pack of standoffs includes 10 sets screws and nuts for securing the top of the standoff to your project.
This black anodized aluminum bracket lets you securely mount typical NEMA 17-size stepper motors to your project. The bracket features several slots and holes for a wide variety of mounting solutions, and four M3×6mm screws are included for securing the motor to the bracket.
These are very handy. They are simple angle brackets with one threaded and unthreaded hole. Use them for connecting PCBs at 90 degree angles, mounting accelerometers, gryros, etc. They can also be used on the universal plate set for mounting all sorts of sensors and such.
Heatsinks are used to dissipate heat from components which generate heat that might affect its performance or lifespan. Be sure to grab some heatsink compound or thermal tape to ensure maximum efficiency.
A low-cost pack of heat sinks that are perfectly sized for the Raspberry Pi. Attach each heat sink to the Pi using the attached self-adhesive layer, and get your Pi running 10 degrees cooler.
Get that heat sink stuck on good and strong with 3M's thermal tape. Specifically designed for attaching heat sinks to ICs. Works better and is less messy than thermal...
Copper tape has countless applications in electronics from creating low-profile traces for electrical components to RF-shielding and antenna-making. Copper tape is even used to join things together using solder, like the stained glass on Tiffany lamps.
This spool of enamelled copper wire is approx. 57m in length is ideal for crossovers networks, custom chokes and inductors. Tinned copper wire ideal for PCB links, breadboards etc.
Adhesive Copper tape is a staple of any modern, STEM classroom. This roll of copper tape has conductive adhesive on one side, separated by a paper backing to the rest of the roll meaning you can cut it down, break it up and use it just as your classroom requires. It's one of the best DIY tools you can have at your disposal.
Attaching moving parts together can be challenging in a robotics project due to different mounting methods, and having the correct hubs and mounts can help immensely.
These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 3 mm diameter motor shafts. The set includes two hubs, two M3 set screws for securing the hubs to motor shafts, and one 1.5 mm Allen wrench for use with the set screws. Each hub has four threaded mounting holes for M3 screws (not included).
