36 Tooth Pinion Gear

The 36 tooth 8 mm REX bore pinion gear is now available from goBILDA. The bore perfectly matches their 8 mm REX shafting to create a positive drive. While little work is left for the set screws, goBILDA put two of them in for good measure.

This particular gear is able to be meshed with an 84 tooth hub gear spaced 48 mm away for a 2.33:1 ratio, or it can mate to a 24 tooth gear to create a very compact 1.5:1 ratio only 24 mm apart. If your build provides the freedom to adjust the spacing between your gears, it’s able to mesh to any MOD 0.8 gear that suits your needs. The counterbore on the top side of the gear allows you to run right up against an 8 mm bearing without the use of a shim. Price is $8.99.

40 Tooth Pinion Gear

The 40 tooth 8 mm REX bore pinion gear is also now available from goBILDA and perfectly matches the 8 mm REX shafting to create a positive drive as well. There are two set screws.

This gear is able to be meshed with an 80 tooth hub gear spaced 48 mm away for a 2:1 ratio, or it can mate to a 20 tooth gear to create a very compact 2:1 ratio only 24 mm apart. If your build is able to adjust the spacing between your gears, it’s able to mesh to any MOD 0.8 gear you choose. The counterbore on the top side of this gear allows you to run right up against an 8 mm bearing without the use of a shim as well. Price is also $8.99.

30 Tooth Miter Gear

The 8 mm REX Bore Miter Gear from goBILDA is able to mate with any other 2315 Series Miter Gear. A miter gear is a specific type of bevel gear.

Two mating miter gears create a 1:1 ratio, and transmit power at a 90 degree angle due to the 45 degree pitch cone angle.

The underneath side of this gear has been dished out to allow a thrust bearing to set the location of the gear (relative to the inside wall of an 1120 Series U-Channel) and counteract the potential spreading forces in the most extreme applications.

Additionally, the 32 mm shelf on the back will allow a 32 mm diameter component such as goRAIL, goTUBE, or a Sonic Hub to nest down in the cavity and fasten with M4 socket head screws. Price is $12.99.

38 mm Pitch Steel Set Screw Sprocket

This 10 tooth sprocket from goBILDA has a 6 mm D-bore to perfectly match 6 mm D-shafting, as well as the D-shafts used on goBILDA’s 5202 Series Gear Motors.

The steel construction provides excellent strength and wear resistance. Price is $7.99.

8 mm Pitch Steel Set Screw Sprocket

This 10 tooth sprocket from goBILDA has an 8 mm REX bore to perfectly match their 8 mm REX shafting.

ts steel construction also provides excellent strength and wear resistance. Price is $7.99 as well.

Learning Platform for Arduino

Dr. Duino has expanded its line of rapid learning and prototyping platforms with its latest Explorer edition and an updated Pioneer version.

Building and tinkering with electronics is much easier with these Arduino compatible shields. They are complete compact learning and prototyping systems which are perfect for anyone interested in electronics.

Designed with the beginner in mind, the Pioneer Edition helps you easily learn about the world of electronics through hands-on projects. Designed with the experienced user in mind, the Explorer edition helps you build and test your electronic concepts quickly.

It’s jam-packed with powerful features, which include:

128x64 line character and graphics OLED
Power options
Bluetooth LE
Prototyping area
Eight channel addressable LEDs
Mini breadboard
And more ...

The Pioneer is Arduino Uno compatible, while the Explorer is compatible with the Uno and Nano versions.

Expansion packs are also available for both the Pioneer and Explorer. Both platforms are currently on sale.

Programmable USB Keyboard Controller Module

Saelig Company, Inc., has introduced the KeyWarrior28: the smallest controller of the KeyWarrior family with a great deal of functionality that is more than just standard keyboard functions.

The KeyWarrior28 — available as a 3.3V QFN28 chip or DIL28 module — controls up to 64 keys in an 8x8 matrix. Just a USB cable and the keys are connected to the module. The functionality of the keys is programmable via a USB port and stored in internal Flash memory. For instance, it can offer a key-operated mouse function or media and application controls like Play, Pause, Mute, Start Browser, etc.

Each individual key can be programmed with either a single key code, a key code plus a modifier (shift, ctrl, alt, gui), a macro, a mouse function, a media/application control, or an FN key. The two optional FN keys give the ability to switch to a second or third key layout.

Like the modifier keys, FN keys can be programmed to act as ‘locking’ or ‘sticky’ (locking, but only for the next key). This allows mode switching or single finger operation.

Each of the 19 macros can be programmed on to any of the keys. A maximum of 31 key codes can be in each macro. There are three different types of macros. A static macro acts as if all keys in the macro are pressed at the same time. Typing macros activate each code just momentarily. This allows repeating characters, special character use, and upper/lower case in the macro. Cell macros work like the text input on phones with numeric keypads. Pressing the key again removes the last character and replaces it with the next.

The KeyWarrior28 works with existing system drivers and does not require special software. Each unit has a unique serial number and a built-in counter to register the number of erase cycles. KeyWarrior modules and ICs are designed by Code Mercenaries. Pricing starts from $12.20.

Waterproof Smart Servos

Tthe DYNAMIXEL XW series of smart servos are ROBOTIS`first line of IP level models, featuring a certified IP68 rating which means they’re good at one meter for a 24 hour duration. The servos are designed for use in wet environments, underwater, and any outdoor applications where a sealed servo is necessary. The XW series come with a separate waterproof cable and extension cable.

Features include:

Six operating modes: torque control; velocity control; position control; extended position control; current based position control; and PWM control.
Profile control for smooth motion planning.
Improved heatsink featuring an aluminum case.
Hollow back case minimizes cable stress (three-way routing).
Direct screw assembly to the case (without nut insert).
Energy saving; reduced current from 100 mA to 40 mA.
28.4% reduced volume compared to the MX-106.
Supports synchronous control mode.

Dual 60A Speed Controller

The Sabertooth Dual Drive Board now available from AndyMark is acceptable for high powered robots up to 120 lbs in combat or up to 1,000 lbs for general-purpose robotics. It can supply two DC brushed motors with up to 60A each. Peak currents of 120A per channel are achievable for a few seconds. Overcurrent and thermal protection integrated into the controller ensure you’ll never have to worry about killing the driver with stalls. Dual motor control can be operated via analog voltage, radio control, serial, and packetized serial. Independent speed and direction operating modes make it the ideal driver for tank-style robots. Price is $190.

The operating mode is set with the onboard DIP switches so there are no jumpers to lose and screw terminals for connections mean no soldering is required. This controller also has synchronous regenerative capabilities. The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse. Sabertooth also allows you to make very fast stops and reverses, giving your robot a quick and nimble edge. A built-in 5V 1A switch-mode BEC can supply power for your receiver or microcontroller, as well as 3-4 standard analog servos.

The lithium cutoff mode allows Sabertooth to operate safely with lithium-ion and lithium polymer battery packs. This component is not legal for the FIRST Robotics Competition and FIRST Tech Challenge robots. Features include:
