This project was published in Electronics Australia in Oct/Nov 96. It is a 32 Channel, 40Mhz, fully PC controlled TTL/CMOS logic analyzer with internal/external triggering and trigger delay. Internal triggering is fully maskable (High/Low/Don't Care) on all 32 channels. The whole things fits on one single sided PCB with virtually no wiring!

The High Speed Function Generator was published in the professional electronics section of the Aug 1996 issue of Electronics Australia, and has proven to be extremely popular. The kit is no longer available from any of the kit suppliers. The project is capable of generating 20MHz or greater Sine, Square, Triangle, and TTL waveforms.

If you need an UV LED timer, or a timer for any other purpose you may be interested in the UV LED Controller that was constructed using a PIC 16F628A Microcontroller. There is a schematic and code available however the original project was not documented in English. Have a look at the Google translation that did a decent job of translating this one.

The new PIC18F2550 Project Board was designed as the development platform for student projects. The board features MCU: PIC18F2550 with external xtal, ADC: one channel 0-2.5V sigma-delta converter, Linear Technology LTC2400/LTC2420, 6-channal 10-bit ADC 0-5V, Display: Two connectors for text LCD or GLCD, USB: onchip USB port with type B connector, Power supply: onboard low dropout regulator, rechargeable battery, Code programming: 10-pin header for In Circuit Loader. The board platform is suitable for developing the microcontroller based instrumentation. Students may build the signal conditioning board, plugs it to PIC project board, develops the code and programs it with loader cable easily.

This is a PLL controller that works with the VCO/Modulator that I designed. Use these two modules together for a complete baseband-capable exciter unit. This PLL controller features a rock-stable crystal controlled reference, in conjunction with a programmable dividing network which allows the transmitter to be tuned in 100Khz steps from 79.9Mhz to 109.7Mhz by means of digital thumbwheel switches. Oscillator, buffer and driver stages use 2N3866 power RF transistor and output stage used 2N3553 4W RF transistor,
