This page contains GIF images of the circuit diagram for the Solution interface, the PCB artwork, the board layout, a typical side elevation of the assembly, a parts list, some hints and a little about troubleshooting. This is a self-extracting 2. 5MB file; although Solution variants aren`t listed, the same software is used for all the older co

mputer types (just use the Vyper version!). Logbook data created with the old "DiveLog" software can be imported into it. The pin numbers for the serial port are for a 9 pin "D" connector as is usually fitted to COM1 on most PCs. They must not be used with a 25 pin connector, refer to your PC`s handbook for the functionally equivalent pin numbers, alternatively 9 pin to 25 pin converters are readily available from RS, Maplin and Tandy. The pcb image is viewed from the copper side of the board to enable those without access to a laser printer to copy the pattern onto copper-clad board with an etch resist pen. The diameter of the pillars used on the prototype prevented the Suunto being attached to the interface without first removing the protective plastic screen; by using smaller diameter pillars it may be possible to leave the cover in position. Ignore the board outline and cut the board to suit the box you intend to use. You may need to profile the sides of the board to avoid the pcb guides inside the box. All component holes are 0. 8mm, those for the test pins and pillars should be suitable for whatever parts you use. 1. 5mm holes were drilled "above" the cable terminations, the individual wires were passed through these to provide some degree of strain relief for the solder joints. Please note that I built mine into a second-hand box that didn`t have a lid, I had to fabricate one from a piece of aluminium. The mechanical...
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.....
