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.
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.
The 8 mm REX Bore Miter Gear from goBILDA is able to mate with any other 2315 Series Miter Gear. A mite4r 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.
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.

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.
Saelig Company is also now offering the four-channel PicoScope 6000E Series 500 MHz oscilloscopes which provide eight to 12 bits of vertical resolution, and up to 5GSa/s sampling rate with 4GSa memory, allowing these scopes to display single-shot pulses with 200ps time resolution. The three four-channel models added to the existing eight-channel 6000 series are the PicoScope 6403E with 300 MHz bandwidth and eight-bit A/D resolution, the PicoScope 6404E with 500 MHz bandwidth and eight-bit A/D resolution, and the PicoScope 6424E with 8, 10, or 12 bits “FlexRes” resolution. The screen update rate is 300,000 waveforms per second.
All models can operate with an extra four bits of resolution with the enhanced vertical resolution software feature — a digital signal processing technique built into PicoScope 6.
Additionally, these oscilloscopes offer 8 or 16 optional digital channels when using the plug-in TA369 MSO pods, enabling accurate time-correlation of analog and digital channels.
All 6000E models include a 14-bit 200 MS/s 50 MHz arbitrary waveform generator (AWG). Its variable sample clock avoids the jitter on waveform edges seen with fixed-clock generators and allows generation of accurate frequencies down to 100 μHz. AWG waveforms can be created or edited using the built-in editor, imported from oscilloscope traces, loaded from a spreadsheet, or exported to a .csv file. The SuperSpeed USB 3.0 interface and hardware acceleration ensure that the display is smooth and responsive even with long captures. The free PicoScope 6 software includes decoders for over 20 serial protocols.
With up to a million points, PicoScope’s FFT spectrum display has excellent frequency resolution and a low noise floor. A click of a button will display a spectrum plot of the active channels, with a maximum frequency of up to 500 MHz.
Using a 4K monitor attached to the controlling PC, PicoScope 6 software can display more than ten times the information of ordinary oscilloscopes. PicoScope software also supports dual monitors, allowing instrument control and waveforms displayed on one, and large data sets from serial protocol decoders or DeepMeasure results on the second monitor. An optional Pico Oscilloscope Probe Positioning System holds a test board firmly, as well as positioning probes hands-free for up to eight probes simultaneously. Probes with compression tips make contact with points of interest on a PCB and remain in contact while measurements are taken with PicoScope software.
The 6000E’s four or eight analog channels have the timing and amplitude resolution needed to reveal signal integrity challenges such as glitches, runts, dropouts, noise, distortion, and ringing. This series gives the waveform memory, resolution, and analysis tools needed to test today’s high performance embedded computers and next-generation embedded system designs. The compact design of the PicoScope 6000E (9.7 x 7.6 x 2.5 inches) means that it fits easily on any workbench, whether in the laboratory or at home.
Finally, Saelig now offers Siglent SSG5000X RF Signal Generators which generate analog and vector signals over a frequency range of 9 kHz to 4 GHz/6 GHz with a 0.001 Hz frequency setting resolution. They offer excellent performance in phase noise, spectral purity, bandwidth, EVM, and output power. The internal IQ modulation generator and waveform playback function on the –V models make it easy to create even the most complex signal types. They also cover the most important RF band for digital wireless communications and include standard waveform files.
The SSG5000X’s 5” color touch screen makes controlling the instrument fast and intuitive. It produces a maximum output power +26 dBm (typ) with phase noise of -120 dBc/Hz at 1 GHz, 20 kHz offset (typ). The ARB Mode can be used to play back digital communication waveform files, while the Custom Mode on the –V versions can generate IQ modulated signals such as QAM, PSK, ASK, FSK, and a sample rate up to 120 Msps. Frequency sweeps can be performed in linear or logarithmic steps.
AM, FM, and PM analog modulation can be accomplished with internal, external, or Int+Ext sources. Built-in digital communication waveform files such as 5G-NR, LTE, WCDMA, WLAN, BlueTooth, and CDMA are also available.
The SSG5000X can add real time AWGN to modulation signals when testing receiver performance or quickly simulate noisy RF environments. It supports multi-tone signals consisting of up to 20 sine wave frequencies.
This is helpful for audio measurements, amplifier and receiver non-linear distortion tests, and ground and satellite communications tests.
Flatness correction is often needed to compensate for transmission line losses or switching impedances. The SSG5000X supports flatness correction with an external power sensor (not included) and is compatible with the most popular USB power sensors on the market.
Standard interfaces include USB Host, USB Device (USB TMC), LAN (VXI-11, Socket, Telnet), and GPIB (opt), and PC control is available, even remotely via a web browser.
The SSG5000X RF signal generator series provides an engineer with an output library of the most common protocol signals and the flexibility to create custom formats to test the limits of new designs. With powerful functions and a wide frequency range, SSG5000X generators are helpful in a wide range of application fields.

Cal Test Electronics has introduced new High Current Test Leads, model CT4043-200. This assembly is great for a power supply, load, or battery analyzer test connections. On each end, there are heavy duty spade connectors with 8 mm openings to lock tight onto binding posts or terminals. As these test leads are capable of carrying up to 60A through their two meter length, concerns over the test lead capacity when making high current measurements are answered.
Keeping the black and red leads bound together is a flame retardant mesh sleeve. On both sides of the sleeve, there is at least 10 cm of unbound black and red cable giving plenty of freedom from even the most awkward connections.
The CT4043-200 is made of highly flexible silicone jacketed lead wires, so stiffness is eliminated. The conductors are 19 strands of copper wire contributing to the very flexible and supple feel. Price is $85.
