Ideal for running network devices such as small switches, home routers, and WLAN access points.
You can certainly buy desktop power supplies, but they're not cheap. As the current capacity and output voltage quantity increase, so does the price. While a commercial desktop power supply is certainly worth the investment, you may want to consider a cheaper solution. Adapt an old computer power supply for use on your workbench. Computer power supplies have all the voltages you need and some very impressive current capabilities.

This reference design (RD) is for a dual-band CDMA front-end IC for use in automotive applications. The application circuit uses the MAX2323 low-noise amplifier (LNA) with mixer at temperatures up to 110°C. The device is also useful for TDMA, GSM, EDGE, and WCDMA applications. Schematics, bill of materials (BOM), and performance measurements are shown.
Reference design (RD) is a dual-band, triple-mode CDMA front-end IC in a receiver with all 183MHz IFs for processing cellular CDMA. The RD uses the MAX2323, a low-noise amplifier (LNA) with mixer, that is useful for TDMA, GSM, EDGE, and WCDMA applications.
This reference design (RD) is for a dual-band, dual-mode CDMA front-end for Japanese cellular CDMA at 110MHz IF. The RD uses a low-noise amplifier (LNA) with mixer, the MAX2325, that is also useful for TDMA, GSM, and EDGE applications. Schematics and bill of materials are shown.
The project originated when the author purchased an electric motorcycle for his daughter and replaced its original lead-acid gel battery with a lithium battery pack. Due to the lack of smart, cheap and easy to configure lithium battery management systems on the market, the author decided to make one himself.
This design is a PMOD with the ublox NEO GNSS receiver footprint. Able to receive GPS and GLONASS simultaneously.
3D printer filament can be produced from discarded water bottles, which will serve two key purposes: recycling plastic waste and producing 3D printer filament at extremely low cost.
The authors hope that as many people as possible will replicate and improve on this project. Therefore, all CAD, firmware and other resources are open source. Special consideration was also given to ensuring that all parts and tools used in the build process were easily sourced.
NXP's ASIL-D automotive system platform is a reference design that enables high-voltage power inverter control to drive electric vehicle traction motors and DC-DC converters.
The SA636DK evaluation demonstration board is used to evaluate the RF development platform for 110.592 MHz RF and 9.8 MHz IF.
The Sonoma (MAXREFDES14#) subsystem reference design performs accurate AC energy measurement while utilizing a unique, low-cost galvanic isolation architecture. The Sonoma meets the high-accuracy and low-cost needs of energy-measurement applications. This small form-factor design is available for purchase. Hardware, firmware design files, and lab measurements provide complete system information for rapid prototyping and development.
This reference design (RD) is for a dual-band, triple-mode front-end IC using only 85MHz IF centers for processing PCS, cellular CDMA, and cellular AMPS. The RD uses the MAX2323, a low-noise amplifier (LNA) with mixer, that is useful for TDMA, GSM, EDGE, and WCDMA applications.
This reference design (RD) for an RF mixer in the FM (AMPS) signal path custom tunes the output matching circuit to optimize the trade-off between IIP3 and the highest gain. The design features the MAX2324 low-noise amplifier (LNA) with RF mixer for cellular-band CDMA, TDMA, GMS, and EDGE applications.
Plankton help remediate 30-50% of the world's carbon dioxide and provide the foundation for the global food chain, making up the world's largest daily movement of biomass as it travels across the ocean. The shapes, colors, and movements of these billions of creatures are as vast as the oceans that sustain them. Understanding plankton is crucial to understanding the world around us and our impact on it.
One obstacle to this type of research is the sheer size of the area to be explored, as well as limited resources for research fleets and specialized equipment. By developing a method to scale up high-quality visual exploration and documentation, we can greatly increase our understanding of the complex web of life around us, and how we in turn influence it.
