This is the circuit diagram for the Comfile CUSB-36R Programmed Christmas Lights. If it is a little hard to read drop me an email at keithsw1@yahoo. com and I will return a more detailed schematic. Basically the Comfile CUSB-36R can either directly drive mains powered devices or it can drive relays to switch mains powered devices. There are two gro

ups of 8 in this circuit diagram. I have chosen to switch ports P40-P47 directly. This limits their total current draw to 5Amps which is protected in this diagram by the 5A fuse. Make sure you wire this in correctly and test that when the fuse is removed the circuit stops working. I accidentally miswired my fuse and burnt out one half of my circuit due to too much current draw. The other inputs P11, P12 and P13 are attached to a Cat-5 lan cable which connects to the Velleman K8055 and are used to synch the computer to the lights that are flashed by the CUSB-36R. There is also a 24V line which is used to power the relays the K8055 will close to trigger the P11, P12 and P13 inputs. To do the power sockets on the cheap I bought 16 2m Arlec extension cords and cut the plug end off it. This works really well as the leads hang out of the box which means the box does not need a large surface area to hold all the sockets.
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.....
