POQiTX, POQiRX, and BLiVITs, oh my! [130162-I]
Many people are tinkering around with RC controls and robotics and trying to install independent sources of power into their projects. Most are fortunate not to have blown the works either on their project, or the test instruments themselves. Here is my answer to this, a fully isolated and floating regulated power supply, with the capability to charge a lithium cell either through U > Read more
USB Barostick (120481)
Author's prototype is working, but his PCB was designed in Sprint Layout and he advises to make a new design because the PCB doesn't really fit into the USB-stick case. Started collecting data, footprints and suppliers for the components of this project. > Read more
USB record digitizer with RIAA correction
When you want to digitize vinyl records with a computer you need either a preamp with RIAA correction or use some kind of correction software. In this project I want to build USB audio interface with RIAA correction.

USB-DMX Scene Controller
This stand-alone data logger displays pressure, temperature and humidity readings generated by I2C-bus sensors on an LCD panel, and can run for six to eight weeks on three AA batteries. The stored readings can be read out over USB and plotted on a PC using gnuplot. Digital sensor modules keep the hardware simple and no calibration is required.
You’ll be surprised first and foremost by the size of this USB/serial converter — no larger than the moulded plug on a USB cable! And you’re also bound to appreciate that fact that it’s practical, quick to implement, reusable, and multi-platform (Windows, Linux, etc.) — and yet for all that, not too expensive. > Read more
The design has ripened to the extent that a real PCB can be presented to start experimenting for real.
