PSU-8 (triple rail linear PSU) |
|
A 3-rail (2 x positive and 1 x negative) adjustable linear regulated power supply. This PSU was developed for applications which require two rails for audio circuits (+/- 15V, +30V/-10V etc) and a separate supply for noisy circuits such as LED indicators, relays, logic modules etc. PCB's are double-sided PTH and are available for purchase. Please use the contact form for enquiries. |

2-Channel VU Meter with Calibration |
|
This two-channel VU meter was made using a handful of spare parts I had lying around. It has a front panel calibration, allowing me to calibrate it for mixes using K-20 or K-14 with ease. |

RTU-401 Remote Telemetry Unit |
|
The RTU-401 module is a small remote telemetry unit designed for general purpose home control applications. Communications uses RS422 multidrop serial and allows up to 16 of them to share a serial line. The I/O consists of 8 opto-coupled digital inputs, 8 open-collector digital outputs (to drive relays etc) and 4 10-bit analogue inputs. It is based on a PIC16F877 device operating at 20MHz and runs from a 9-24V AC/DC supply. There's also an on-board temperature and incoming supply measurement. |
