There’s a growing series of good videos covering ESP8266 Tips & Tricks on ACROBOTIC’s YouTube channel. The ESP8266 has become quite a darling in the IoT world, and a seriously cool community is growing around it. NodeMCU devkit picture by … Continue reading
National Instruments hosts a very handy table for finding IPC 7351 equivalents to JEDEC and IEC package names. I’m linking to a local PDF version for convenience.
I’ve added a bunch of modules to my KiCad library. These have not yet been vetted, so approach with caution. Here’s what’s new or changed: New library mfk-ipc-7351-diode.mod with: mfk-SOD3716X135N (SOD-123 diode) New library mfk-smd-not-ipc.mod with: mfk-fairchild-SOT23 (Fairchild version of … Continue reading
Audio by Van Alstine has adopted my discrete Class A audio module into two of their products. The Vision DAC uses the module in its differential anti-imaging filter and output stage and the Vision SL Preamp uses it for line … Continue reading
As part of my Open source audio remote control initiative, I’ve just published Volume-AlpsRK16814MG, an open source hardware design that integrates a high-quality Alps motorized quad potentiometer with an H bridge. The design lets you control the motor’s direction using … Continue reading
I’ve started a FLOSS remote control receiver project for DIY audio preamplifiers. I think it’s just about good enough to make public. Remote control is one of the more challenging things for an audio DIY person to implement, so I … Continue reading
A couple mockups for an audio preamp display using dirt cheap character LCDs and the BigCrystal library for Arduino.
Here’s a workaround I used in a KiCad layout that involved a DRC error with a module’s (non-conducting) mounting pin. The mounting pin is physically close enough to an electrical pin that it makes the DRC clearance test fail. The … Continue reading
Pictured here is a prototype of a miniaturized version of the audio module I’ve been working with for the last few months. A high-end audio manufacturer is currently evaluating the module for use in a new line of products. More … Continue reading
