Plant Watering Watcher - Version II - RED - Page18
http://www.redcircuits.com/Page18.htm
A flashing LED signals the necessity to water a plant. Very low current consumption - 3V powered circuit. This circuit is intended to signal when a plant needs water. A LED flashes at a low rate when the ground in the flower-pot is too dry, turning off when the moisture level is increasing. Adjusting R2 will allow the user to adapt the sensitivity of the circuit for different grounds, pots and probe types. Extensive tests were also carried out with different flower-pots and probes. Although, as can b...

Based on electromagnetic-field radiation. Place it under the pillow - Built-in timer. Generates a natural electromagnetic-field. Makes easier to fall asleep. Induces a prolonged and sound sleep without drugs. Many people experienced sleeping well in natural surroundings, into a tent or a wooden hut. This fact is due not only to the healthy atmosphere but also from our unconscious ability to perceive natural Earth's magnetic-fields. NB Basic ideas for this circuit are coming from German papers).

Temperature-controlled Fan - RED - Page70
http://www.redcircuits.com/Page70.htm
Gradually increases speed as temperature increases. Widely adjustable temperature range. This circuit adopt a rather old design technique as its purpose is to vary the speed of a fan related to temperature with a minimum parts counting and avoiding the use of special-purpose ICs, often difficult to obtain. The circuit is designed for 230Vac operation. If your ac mains is rated at about 115V, you can change R9 value to 15K 2W. No other changes are required. In this circuit, if R1 and Q1 are not mounted in...

To achieve perfect aim, just shoot then call anything you hit as target. Sunday, October 11, 2009. Prices of Watch Winders. From my previous manufacturing experience, I know about 20% of the product cost usually goes to materials while 80% goes to other cost factors such as Manufacturing, R&D, A&P, Administrations, etc. I can’t estimate a particular unit cost unless I do an exercise taking it apart and getting quotes on those various parts. But I won’t go down that avenue. And how reliable are they?

To achieve perfect aim, just shoot then call anything you hit as target. Friday, November 6, 2009. Your First Homemade Watch Winder. Once you’ve finally assembled the watch winder unit, you’ll truly be excited flicking the power switch for the first time. Well, I was! This unit has 4 modes of operation: -. At Rest, the circuit draws only about 2mA and depending on the weight of the load, when Rotating it draws as high as 60mA. This is how it looked like fully. Assembled from the front.

To achieve perfect aim, just shoot then call anything you hit as target. Monday, October 26, 2009. Want to build a Cheap Watch Winder? Every where I look, there are many people asking, sourcing, sharing, discussing, swearing, advertising, debating, commenting and lamenting about cheap watch winders in the web. How exactly is cheap? To make my point, let’s begin to make a real simple cheapo watch winder! Basically, a watch winder consist of the following: -. Lots of imagination, patience and luck. Once I’...

To achieve perfect aim, just shoot then call anything you hit as target. Monday, September 28, 2009. Automatic watches have mainsprings that wind in a clockwise, anti-clockwise or either way. There are also a minimum number of turns that would maintain the torque of the mainspring, thus keeping them wound. A manufacturer of an automatic timepiece would specify the minimum TPD for that particular watch model (caliber) and its best to set the winder to meet this requirement. We are truly blessed to hav...

To achieve perfect aim, just shoot then call anything you hit as target. Thursday, October 29, 2009. Testing the Homemade Watch Winder Circuit. The circuit itself has very few components, and in the picture you’ll see more jumper wires than actual parts going into the circuit. I’ll solder the circuit to a veroboard once I’ve confirmed the circuit, and in that way, you’ll get to see how the whole circuit looks like. Timings were recorded using the lap-time function on my cell phone. The motor seems to tur...
