The LTC6268-10 is a single 4GHz FET input op amp for high dynamic range and high speed transimpedance amplifier (TIA) applications. This new decompensated amplifiers extend the speed and dynamic range capabilities of this ultralow bias current op amp family for applications with a gain of 10 or higher. Input bias current is 0.9pA max […]

This past winter I designed and constructed a stereo vacuum tube amplifier based off of the TubeLab SimpleSE design. Since many people asked about it at Maker Faire Detroit, I thought I would post a link to the build photos and some more details. Check out the build album below! Some more technical details: Preamp: […]

About the Project Here is a fascinating and nostalgic project that kept me up many, many nights last summer (creating it, not playing the game!). I had long thought it would be exciting to try to generate video from a PIC, and with built-in A/D converters available for the paddles, the game of Pong seemed […]

DC-DC converters are widely used components that convert DC power from one voltage to another, producing a regulated output voltage. These devices are used in many electronic products, including laptops, mobile phones, and instrumentation. Like any device, DC-DC converters need to be characterized by manufacturers and by engineers evaluating them for a design. Given the […]

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. We are widely familiar with the Password based e-locks and might have installed in our house. But we are going for Electronic locks made by any company when you can make one […]

Introduction Just a handful of components builds an 8-pin microcontroller based circuit for temperature logging via a serial port; small, fast, and acceptably accurate. Features provides real-time data to your computer via serial port, interfaces up to four DS1820 temperature sensors, absolute accuracy near 0.5 degrees celcius (as per DS1820 specifications), relative accuracy near 0.01 […]

Watch signals propagate through basic digital circuits. Emulate any two-input logic gate using just one rLogic board and one jumper. To order rLogic+, the breadboard compatible variant, simply order normal rLogic. When the survey is sent out you will indicate which you would like. rLogic is a basic breakout board for the Fairchild Semiconductor TinyLogic® […]

This is a brief review of the capabilities and ease of use of three of the most interesting, innovative and downright disruptive web-based EDA tools: EasyEDA Upverter Autodesk 123D Circuits (formerly Circuits.io) The same simple astable multivibrator circuit is entered into each tool and the design process followed through simulation (where offered), to PCB layout […]

The Nomad 883 is a ready-to-run CNC Mill that’s at home in any environment. UPDATE #1: Watch Jorge and Apollo pitch The Nomad to Leo Laporte on the new TWiT show, “I’d Fund That” at http://www.youtube.com/watch?v=eNqggrDxHhI UPDATE #2: Stretch Goal Met!  Every machine comes with the Flip Jig for two side machining and INNER CIRCLE pledges […]

The fact of having a CNC available at home gave me the freedom to build stuff more easily and quickly than before. Without this machine parts would take some time to manufacture and most likely would not end so perfect. This caused new ideas to be easily implemented. This was one of those ideas that […]
