Centrifugation is a powerful method for isolation of compounds such as DNA, proteins, oil or membrane vesicles from a complex mixture. The RWXBioFuge was designed to bring this powerful tool into the hands of labtechnicans, scientists, hackers, makers, diybio-ers and those who cannot afford to procure A-label equipment in low-resource settings. It may also be […]

Texas Instruments announced plans for the Regency TR-1, the first transistor radio to be commercially sold, on October 18, 1954. The move was a major one in tech history that would help propel transistors into mainstream use and also give new definition to portable electronics. TI was producing germanium transistors at the time, but the

Abstract: A PIN photodiode, four low-noise op amps and a comparator are used to detect individual photons of gamma radiation. The schematic, design considerations and component selection are discussed. The circuit of Figure 1 includes a PIN photodiode that detects individual photons of gamma radiation. When a photon strikes a depletion region created by reverse bias

Researchers at Stanford University have created a fast-charging and long-lasting rechargeable battery that is inexpensive to produce, and which they claim could replace many of the lithium-ion and alkaline batteries powering our gadgets today. The prototype aluminum-ion battery is also safer, not bursting into flames as some of its lithium-ion brethren are wont to do.
USB connected TI TMS320F28027 based ZRLC Tweezers with Most Digital multi-meters measure Resistance and Capacitance and LC-meters can measure Inductance and Capacitance. Presented here is a ZRLC meter which can measure Resistance, Capacitance, Inductance and Complex Impedance. The hardware is built around a TMS320F28027 micro-controller an 8-port-analog-switch ADG714 from analog-devices and a Microchip rail-to-rail dual
