This is a write-up for a 2011 update to the 2008 lanc circuit project, lets call call phase 2. This update allows the use of a cx700v camera to be used in the same underwater video housing. Such a housing is called a generic housing. A generic housing enjoys a long life (as it is supposed to) as they can be reused for newer cameras continuously

. A generic housing saves money for the owner as he does not have to repurchase the housing for every camera. These digital video cameras have been getting better every year, allowed by my wallet about every 4 years. Phase1 of this project is written up here 1998 ccd-tr930 My first camera, HI8 tape, just threw it in the housing and jumped in, didn`t know anything about holding camera steady or finding good shots. No lights. Lots of video noise at any amount of low light, Attached wide angle lens to camera. Viewfinder was large enough to see most of the image through the rear door window. 2001 trv17 Mini-dv, fully digital picture. Better low light. Attached two Shockwave dive lights (150 lumens each) to the housing arms. This allowed night dives. But lights were not proper floods. Camera had a provision for taking digital pictures and white balance but housing did not offer access to these features. Attached wide angle lens to camera. 2008 hdr-hc9 (PHASE1) Mini-dv HiDef HDV format. (meg2) Much better daylight clarity, better low light, . Attached a heavy wide angle lens to camera. Housing circuit boards were modified by me to assign a button to take still pictures. See phase1. Added small LCD monitor to rear of tray to be visible from rear of housing. 2010 same Housing and camera modified to accept external flash, S2000 was attached, Video lights changed to PROV8LED (400lumens each). Much more light available now. Now we are...
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.....
