Want to make a TV

INTRODUCTION

Incredibly small video cameras have recently become available at reasonable prices. Small televisions are available for very little money at online auction sites such as eBay. It is now possible to build a miniature short-range wireless video system with off-the-shelf parts. This wireless nature of this circuit is not suitable for long distance operation, the video modulator just provides a simple method for interfacing the video signal to a standard TV. Transmission distance is limited to a few feet.
TheoryThe 12VDC supply provides power for the camera and video modulator circuits. The video from the camera is fed into the video input of the modulator circuit. The modulated RF from the modulator is fed into a small antenna. Use of a dipole antenna that is resonant at the frequency of the modulator can extend the signal range. The RF travels across a short distance to the Sony Watchman TV receiver. A black and white image magically appears on the TV screen.
ConstructionThe camera's video signal is connected to the video modulator with an RCA jumper cable. Power to the camera and video modulator is connected to the 12V power supply. Be careful with polarity, reversing the leads may damage the modulator. The camera that was used had reverse polarity protection built in. The modulator's RF output signal is connected to a small antenna, the antenna can be made with two short lengths of #16 gauge solid wire. Alternately, for long distance wired operation, the RF signal can be fed into a length of 75 ohm coax cable with a 75 ohm terminating resistor across the far end of the cable. Connect the remote center conductor of the cable to the TV antenna through a 330 ohm resistor.
UseTurn the power for the camera and modulator on, turn on the TV. Tune the TV to the channel of the RF modulator, fine-tune the TV for the best picture. For full-time operation, use the appropriate AC adapter for the watchman. If battery operation is desired, run the TV from its internal batteries and use a 12V battery for powering the camera and modulator. A rechargeable lead acid battery with a series fuse (and a recharging circuit) is recommended.
A fun use for this system would be to create an engineer's view of a model train layout. A loop of wire near the track would make a good receiving antenna. Power could be pulled from the engine motor circuit using a bridge rectifier feeding into an electrolytic capacitor, just make sure not to exceed the camera's 12V maximum supply voltage.
Parts
Miniature black and white video camera, 12VDC, Model PC-206XP
Video modulator block, Jameco 141639CJ or equivalent
Sony Watchman miniature TV
12V DC power supply, beware of wall-warts - they often have inaccurate voltage ratings.

Make Your Own Solar Powered Reading Lamp

Solar Powered Reading Lamp
(C) G. Forrest Cook July 31, 2004
IntroductionThe goal of this project was to produce a self contained reading lamp that could be used by students in developing countries for reading at night. The circuit can be used for a wide variety of lighting applications.
The reading lamp consists of a small solar panel, a standard UPS style lead acid battery, and an LED circuit board. The circuit board contains a low power solar charge controller (regulator), a set of 8 white LEDs, a switch, an LED current regulator, and a low voltage disconnect circuit. The circuitry will insure a long battery life by preventing over charging and excessive discharging. The circuit was designed to work with lead acid batteries, it should also work with a string of 10 NiCd cells. Both the charge controller and LED regulator circuits can be used independently for other applications.
Newer VW and Audi automobiles come with small solar panels for keeping the battery charged in the sales lot. These panels are available on eBay for around $15 and are a perfect fit for this project. An inexpensive 12V 7AH lead acid gell-cell battery that is typically found in a computer UPS is also a good fit for this circuit. Be sure to use a new battery.
SpecificationsSolar charging current: 150 ma - 1 Amp
Voltage drop through charge controller: 0.5V typical
Nominal battery voltage: 12 Volts
Battery rating: 3-7 amp hours
LED lamp current: 100ma regulated, 25ma per LED pair (1.2W nominal)
LED regulation range: constant light level from 11V to >15V
Low voltage disconnect: gradual current drop from 10.8V to 9.8V
Night time battery current drain with LED off: almost zero
Light duration: approximately 70 hours with a 7AH battery
Charge time: approximately 40 hours max, several hours typical
TheoryCharge Controller: The charge controller section consists of an LM2941CT low dropout voltage regulator and a 1N5817 schottky diode. The regulator determines the battery full voltage, this set-point is adjusted by the 5K 20 turn trimmer potentiometer. The 1N5817 schottky diode prevents the battery from discharging through the voltage regulator during the night. It also protects the circuitry against reverse battery connection. The V727 part is a transzorb, it absorbs lightning induced voltage spikes above 27V. The fuse prevents short circuits from burning up the battery wiring.
LED Circuitry: The 8 white LEDs are connected in series with an LM317L IC that is wired as a constant current regulator. The 13 ohm resistor sets the regulated current to 100ma. This current is split evenly through the four pairs of LEDs. The 33 ohm resistors help to keep the current through the four LED pairs balanced evenly. The 2N3904 transistor, 1N5239 zener diode, and 470 ohm resistor form the Low Voltage Disconnect (LVD) circuit. Current through the LED starts to drop when the battery voltage drops below 10.8V, the circuit shuts off almost all of the current when the battery drops below 10V. The 1N5817 schottky diode blocks current flow in the event of a reverse battery connection.
ConstructionThe lamp consists of a small wood battery box and a vertical board for holding the LED assembly and solar panel. A small carrying handle protrudes from the top of the vertical board. The LED assembly consists of a small printed circuit board and the various parts. It is sandwiched between a piece of hard-board and a piece of clear plexiglass to protect the circuitry from physical damage and short-circuiting. The battery used for this device is a standard 12V-7 Amp-hour gell cell UPS battery. The solar panel is home-made, two or three parallel-wired GM-684 12V 60ma solar panels (p/n 08SLC09 from Elecronix Express), would be a good substitute.
Alignment

• Connect the board's BAT - terminal to the battery - terminal.
  Connect the board's BAT + terminal to the battery + terminal.
  Connect the board's PV - terminal to the solar panel - terminal.
  Connect the board's PV + terminal to the solar panel + terminal.
  Point the solar panel toward the sun.
• Measure the connected solar panel's voltage with the meter.
  Measure the battery voltage with the meter.
• The solar panel must be at a higher voltage than the battery for the
  circuit to charge the battery.
• Turn the potentiometer, VR1 25 turns clockwise.
• Monitor the battery voltage, as the battery charges, the voltage should
  rise above 13V.
• When the battery voltage has reached 13.8V or the desired full point,
  turn VR1 counter-clockwise until the battery voltage stabilizes.
• Let the battery charge for several minutes at the full setting, then
  re-adjust VR1 for the final desired full voltage setting.
  UseDaytime: Place the solar panel in a location that gets at least a
  few hours of direct sunlight each day. Turn the LED switch off.
  If the battery is extremely discharged, it may take several days in
  the sun to fully recharge.
  Night: Use the lamp as you would use any other reading lamp.
  If the lamp starts to dim, the battery is almost completely empty,
  shut the light off. If you forget to shut off the lamp, the LVD circuit
  will shut the lamp off when the battery is nearly empty.
  If the lamp is recharged daily, the battery should
  rarely reach the Low Voltage Disconnect (LVD) point.
  

Make your own AA Battery Solar Charger

AA Battery Solar Charger
For higher power solar systems, see the CirKits solar charge controller circuit board kits.

IntroductionThis almost trivial circuit may be used to charge a pair of AA or AAA sized rechargeable battery cells from sunlight. The circuit has been used to keep a Palm Pilot and walkman radio running perpetually. This is an unregulated charger, proper charging is achieved by placing the unit in the sun for a known amount of time, this time varies according to the battery type.
SpecificationsOpen Circuit Voltage: about 4.0V
Closed Circuit Current: about 25ma (depending on the solar cell types)
Charge Current: < 25ma (depending on the solar cell types)
Charge Time AA cells: approximately 1 full day of direct sunlight
Charge Time AAA cells: approximately 1/2 full day of sunlight
TheoryEach of the solar cells develops about 0.5 volts across itself when in full sunlight. The string of 8 solar cells puts out around 4V with no load. When the solar cells are connected to a battery, a current will flow and the battery will charge.
Two versions of the circuit are shown in the schematic, the 8 solar cell panel with a diode is the recommended circuit. The diode prevents the battery from discharging through the cells at night and the 8th cell boosts the voltage up enough to compensate for the voltage drop across the diode. For an 8 solar cell panel, connect jumper J2 and disconnect J1. For a 7 solar cell panel, connect jumper J1 and eliminate SC8 and D1. Typically, the jumpers are not necessary, they are shown in the schematic to illustrate two ways to to build the circuit.
For operation in cloudy weather, it may be useful to add one or two additional solar cells. It is a good idea to temporarily insert an amp (microamp) meter in series with the battery to measure the charging current in various light conditions.
Since solar cells are current-limited devices, it is possible to use the circuit as-is to charge a single battery cell. If one cell is all you ever need to charge, five solar cells and a series diode will be sufficient for the task.
ConstructionLay out the solar cells to determine the size of the circuit board, allow for about 1/4" (1cm) of extra space around all four sides. Cut out one piece of perforated circuit board, one piece of solid PC board, and one piece of 1/8" clear plexiglass in this dimension. File all 3 pieces to achieve smooth edges.
Drill 2 holes down the center line of the 3 pieces while holding them together allowing room for the screws to pass between the solar cells. Mount the two battery holders on the blank piece of circuit board with screws or silicon rubber glue. If the solar cells don't have wire connections, solder thin wires to the cells. Wire-wrap wire works well for this. Be careful not to overheat the solar cells, use a small soldering iron and only touch the cells for a few seconds at a time. The solar cells should be secured to the perf board with a drop of silicon rubber on the back side, or they can be held in place with the wires of the solar cell if you have the right kind of cell. Wire all of the cells in series, plus to minus, connect the two end wires to longer wires that go to the diode and battery holder. Typically, the positive connection is the metal on the back of the solar cell and the negative connection is the wire grid on the blue (front) side.
Using a pair of 3/4 inch 6-32 machine screws and nuts or washers, make a sandwich of the 3 boards. Use the nuts or washers to make gaps between the board layers, it is important to prevent any contact between the solar cells and the plexiglass. The solar cells are very brittle and will break under compression.
If you want to make the panel waterproof, cut 4 thin strips of solid circuit board or other plastic to fit around the sides of the sandwich. Glue these boards to the sides of the assembly with silicon rubber. Apply a small drop of glue to where the screws go through the plexiglass.
AlignmentNone required unless you count pointing the panel at the sun.
UseInsert two rechargeable cells in the battery holders, point the device at the sun, and let batteries charge for a few hours. Larger cells will need more charging time. The solar array should be placed in direct sun, it should not be shaded in any way. It might be a good idea to monitor the battery voltage during the first few charge cycles to get an idea of how much time is needed to reach a full charge.
Do not let the rechargeable cells overheat. If the charger is left outdoors in the summer, the excess heat can cause the cells to leak out their electrolyte goo, ruining the cells. Operating the charger indoors behind a window may help to reduce the heat. Operation behind a window will also cause a drop in the charge current, resulting in a longer charge time.
This circuit works with rechargeable alkaline cells, NICD cells, or any other rechargeable that has a potential of 1.5V or lower per cell. If you build the 7 cell version (no diode), remove the cells at night to prevent discharge through the solar cells.
It is advisable to connect a volt meter across the battery with a pair of alligator clips to observe the battery voltage as it charges. If you have a lot of batteries to charge, it is best to charge cells that are matched by brand. If possible, use cell pairs that start with a similar voltage, this allows both cells to finish charging at the same time.
The NiCd Memory EffectKeep in mind that the so-called NiCd "memory effect" is largely an urban legend that started from a legitimate early 1960s Nasa experiment involving first generation NiCd cells charged and discharged within a very tight voltage range. The two biggest killers of modern NiCd cells are overheating during charging, and reverse voltages applied to the weak cells as the result of the complete discharge of multi-cell NiCd packs. The NiCd cells in cheaper appliances such as cordless phones and portable vacuum cleaners will last a lot longer if they aren't left on the charger 24 hours a day.
Overheating can cause the loss of electrolyte, resulting in lowered cell capacity. Reverse voltage can cause conductive dendrites to grow in the cells making them self-discharge more rapidly. So called "memory effect" dischargers can actually cause the reverse voltage problem if used on multiple cell packs. The weakest cell in a pack will go to zero volts, then negative volts as the stronger cells discharge. Discharging can be a good way to insure that all cells are charged from the same starting point, just be sure to limit the minimum discharge voltage to around 1V per cell. The BatteryUniversity.com has a good article on the behavior of aging NiCD cells, and tips on cell restoration.

Nanotechnology

Nanotechnology the new emerging field has many serets with it. It is a field of applied science and technology covering a broad range of topics. The term "nanotechnology" was defined by Tokyo Science University Professor Norio Taniguchi in a 1974. One nanometer (nm) is one billionth, or 10^-9 of a meter. For comparison, typical carbon-carbon bond lengths, or the spacing between these atoms in a molecule, are in the range .12-.15 nm, and a DNA double-helix has a diameter around 2 nm. On the other hand, the smallest cellular lifeforms, the bacteria of the genus Mycoplasma, are around 200 nm in length.

As nanotechnology is a very broad term, there are many disparate but sometimes overlapping subfields that could fall under its umbrella. The following avenues of research could be considered subfields of nanotechnology. Note that these categories are fairly nebulous and a single subfield may overlap many of them, especially as the field of nanotechnology continues to mature.

Nanomaterials

This includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions.

• Colloid science has given rise to many materials which may be useful in nanotechnology, such as carbon nanotubes and other fullerenes, and various nanoparticles and nanorods.
• Nanoscale materials can also be used for bulk applications; most present commercial applications of nanotechnology are of this flavor.
• Progress has been made in using these materials for medical applications; see Nanomedicine.

Although there has been much hype about the potential applications of nanotechnology, most current commercialized applications are limited to the use of "first generation" passive nanomaterials. These include titanium dioxide nanoparticles in sunscreen, cosmetics and some food products; silver nanoparticles in food packaging, clothing, disinfectants and household appliances; zinc oxide nanoparticles in sunscreens and cosmetics, surface coatings, paints and outdoor furniture varnishes; and cerium oxide nanoparticles as a fuel catalyst. The Woodrow Wilson Center for International Scholars' Project on Emerging Nanotechnologies hosts an inventory of consumer products which now contain nanomaterials.
