It is a 32 Channel, 40Mhz, fully PCcontrolled TTL/CMOSlogic analyser 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! Unfortunately the PCLA is not available as a complete kit from any of the k

it suppliers, and I no longer sell the pre-programmed PLD`s. Only the software is available. So if you want to build it, then I`m afraid you`ll have to make the PCB and program the PLD`s yourself. The PLD`s were designed with the old Lattice Semiconductor ispLSI starter kit, but the newer Lattice development tools are available from the lattice web site. I have not used this new software, and email reports indicate that the files on this page are not compatible with it. I do not know how to solve this issue, so please don`t ask. I have no plans to upgrade this project to new devices or software. The internal schematics for the chips are available on this page, you can use these to program the newer devices yourself. NOTE : I get a *lot* of email about the ispLSI PLDchips in this project. For those of you who are unaware of what they are, they are Programmable Logic Devices, and they are BLANK when you buy them, you MUSTprogram them with the JED files from here in order to get them to work. If you don`t even know this much then you really have no need for this project! Peter Baxter has developed a new Logic Anlyser product that should be on the market around the end of 2003. The delay is due to Business Partner issues, rather than engineering aspects. The earlier kit version completely sold out in 1999. There are no units available and no spare parts. You can look at the website: for info on the kit, but don`t get excited by...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
