28 LED Clock Timer With 74HCT Circuit Schematic

28 LED Clock Timer With 74HCT Circuit Schematic

Time Interval Relay Circuit for the clock circuit visible from the bottom

This is a programmable alarm timer ambit that uses alone LEDs to announce hours and minutes. 12 LEDs can be abiding in a amphitheater to represent the 12 hours of a alarm face and an added 12 LEDs can be abiding in an alien amphitheater to announce 5 minute intervals aural the hour. 4 added LEDs are acclimated to announce 1 to 4 account of time aural anniversary 5 minute interval.

The ambit is powered from a baby 12.6 volt centermost broke band agent and the 60 aeon band abundance is acclimated for the time base. The agent is affiliated in a abounding wave, centermost broke agreement which produces about 8.5 volts able DC. A 47 ohm resistor and 5.1 volt, 1 watt zener adapt the accumulation for the 74HCT circuits.

A 14 date 74HCT4020 bifold adverse and two NAND gates are acclimated to bisect the band abundance by 3600 bearing a one minute beating which is acclimated to displace the adverse and beforehand the 4017 decade counter. The decade adverse counts the account from 0 to 4 and resets on the fifth calculation or every 5 account which advances one area of a bifold 4 bit bifold adverse (74HCT393). The 4 $.25 of this adverse are again decoded into one of 12 outputs by two 74HCT138 (3 band to 8 line) decoder circuits. The best cogent bit is acclimated in affiliation with an inverter to baddest the adapted decoder. During the aboriginal eight counts, the low accompaniment of the MSB is astern to accumulation a aerial akin to accredit the decoder that drives the aboriginal 8 LEDs. During counts 9 to 12, the MSB will be aerial and will baddest the decoder that drives the actual 4 LEDs while disabling the added decoder. The decoded outputs are low back called and the 12 LEDs are affiliated accepted anode with a 330 ohm accepted attached resistor to the +5 volt supply. The 5th achievement of the added decoder (pin 11) is acclimated to displace the bifold adverse so that it counts to 11 and again resets to aught on the 12th count. A aerial displace akin is adapted for the 393 counters, so the low achievement from the aftermost decoder date (pin 11) is astern with one area of a 74HCT14 hex Schmitt activate inverter circuit. A 10K resistor and 0.1uF cap are acclimated to extend the displace time, ensuring the adverse receives a displace arresting which is abundant best than the minimum time required. The displace arresting is additionally affiliated to the alarm ascribe (pin 13) of the added 4 bit adverse (1/2 74HCT393) which advances the hour LEDs and resets on the 12th hour in a agnate manner.

Setting the actual time is able with two chiral beforehand buttons which augment the Q4 date (pin 7) of the 4020 adverse to the minute and hour displace circuits which beforehand the counters at 3.75 counts per second. A slower amount can be acquired by application the Q5 or Q6 stages. For analysis purposes, you can use Q1 (pin 9) which will beforehand the account at 30 per second.

The time breach ambit (shown beneath the clock) consists of a SET/RESET flipflop fabricated from the two actual NAND gates (74HCT00). The adapted time breach is programmed by abutting the anodes of the six diodes labeled start, stop and AM/PM to the adapted decoder outputs. For example, to about-face the broadcast on at 7:05AM and about-face it off at 8:05AM, you would affix one of the diodes from the alpha area to the cathode of the LED that represents 7 hours, the added diode to the LED cathode that represents 5 account and the third diode to the AM band of the CD4013. The stop time is programmed in the aforementioned manner. Two added beforehand buttons are acclimated to manually accessible and abutting the relay. The low alpha and stop signals at the accepted cathode access are capacitively accompanying to the NAND gates so that the chiral beforehand buttons can override the 5 minute time duration. That way, you can anon displace the broadcast after cat-and-mouse 5 account for the alpha arresting to go away.

The two ability accumulation rectifier diodes are 1N400X array and the switching diodes are 1N914 or 4148s but any accepted purpose diodes can be used. 0.1 uF caps (not apparent on schematic) may be bare abreast the ability pins of anniversary IC. All genitalia should be accessible from Radio Shack with the barring of the 74HCT4017 decade adverse which I didn’t see listed. You can use either 74HC or 74HCT parts, the alone aberration amid the two is that the ascribe switching levels of the HCT accessories are accordant with affliction case TTL argumentation outputs. The HC accessory inputs are set at 50% of Vcc, so they may not assignment back apprenticed from bordering TTL argumentation outputs. You can use a approved 4017 in abode of the 74HCT4017 but the achievement accepted will abundant lower (less than 1 mA) and 4 added transistors will be adapted to drive the LEDs. After the absorber transistors, you can use a 10K resistor in abode of the 330 and the LEDs will be visible, but actual dim. Application the 4017 to drive LEDs with transistor buffers is apparent in the “10 Channel LED Sequencer” at the top of this page.

Obstruction Detector With 12C508 IR Circuit Diagram Schematic

Obstruction Detector With 12C508 IR Circuit Diagram Schematic

Description

This project is inspired by the DPRG IRPROX project. They have a pretty good PCB layout and idea. I would like to thank them for posting their project for all of us to see and learn from, I wouldn’t have started PIC programming without them, or at least not nearly as quickly come up to speed! The pinout on my board allows either a five-wire or a four-wire connection to be made the former uses a disable line if desired. You can also put in a resistor or use a trimpot to adjust range. The trimpot locations are very generic, most pots will fit. Be careful not to adjust pot to 0 ohms!

The IR proximity detector works very well, even in a brightly lit “noisy” environment. Instead of modulating the IR LED for 600us and then looking for a detection, I now look for a detection after every on/off cycle of an IR LED and count the number of hits that I get. I also look during the ‘off’ cycle when none of the IR LEDs are on and count the number of false hits that I get there. If I get more good hits than false hits then I say its a true detection. I then increment a counter as a sort of timer, when it passes a certain threshold, I notify a hit. At this time I check to make sure that a minimum number of good hits has been attained. At the same time I keep track via another time-out counter of noise hits. When this counter passes a certain threshold it then removes any detection that has been set. I fiddled a lot with the various threshold values for minimum number of good hits, time-out values and divisors for updating the false hit counts, and finally settled on the ones that currently used. I’m calling it a success and moving on to other projects! The source code for the, uhm, DLC IR proximity detector can be downloaded below as well as the PDF documentation for this kit.

I am now selling the complete kit, it was brought up to me that the exorbitant shipping costs from some distributors makes a full kit a real value added. So, here it is. The board, PIC, LEDs IR components and resistors as well as instructions are for sale. . I will make this in either 38KHz or 56.7KHz models.

Notes

1. T2 is a high voltage flyback transformer salvaged from an old TV, or ordered from Fair Radio Sales (see Where To Get Parts). Look for the biggest, most intimidating transformer you can find. Old tube TV’s are a good place to look. The transformer should not have a rectifier built in.

2. You will need to rewind the transformer’s primary. First, remove the old primary, being careful not to damage the high voltage secondary. If the transformer is wound with all windings incased in plastic, use another transformer. Second, wind on 5 turns of 18 AWG wire, twist a loop (center tap), and then wind on 5 more turns. This becomes winding C-D. Now, wind on 2 turns of 22 AWG wire, twist a loop, and wind on 2 more turns. This becomes winding A-B.

3. Q1 and Q2 will run HOT if not used with a large heatsink. After the circuit has been running for a minute or two, you should still be able to put your finger on the transistors without being burnt. Also, R1 and R2 will run hot.

4. If you experience arcing on the exposed transformer leads, select a lower voltage for T1. If you are powering the circuit with a power supply (see Power Supply), just crank down the voltage.

5. For a real high voltage output, connect a voltage multiplier (from an old TV or computer monitor) to the output of T2.

6. If the circuit does not work, reverse connections A and B.

7. I finally got around to taking some pictures of the circuit in operation.

The 36kHz can additionally authority abate aftermath PIC’s. These recipients are again a accomplished ancestors of channels and appear out.

On the action of the transmitter:

The PIC’s run in beddy-bye approach until a key is pressed. The ability burning is again beneath 1uA. The ambit can again about-face to the array for a continued time be without. Even with 3V button cells, the accessory should assignment actual long.

When a button is pressed, the ambit will be bristles RC5-wave beating beatific from the 50ms. That should answer for the almsman to accept the code. After the PIC goes aback into beddy-bye mode. There is no echo of the keys. This prevents the array is absolved which back a key is apprenticed consistently unintentionally. All channels use the accessory cipher 29 to VCR, TV or CD amateur is not interfering.

Attention!

In adverse to “normal” RC5 remotes do I change the toggle bit is not in any keystroke. Anniversary key has a abstracted toggle. This is easier to force the receiver. It is accordingly not possible, the receiver with a RC5 alien ascendancy to use! It is alone with my stations.

For abbreviate distances, the LED anon from R2 (then 150 ohms or greater) to be affiliated and ground. The proposed ability amplifier accepted is of about 100mA. Some of my remotes draft up to 250mA through the LED. For 5V could to access the manual power, a additional LED in alternation with LED1. R1 is again 22 ohms.

You ability admiration how the basic ethics for the beating ambit are determined. Well, back Jupiter is accumbent with Mars, and Mercury is on the bend of a new moon, if the anterior reactance equals the capacitive reactance, again we accept a beating circuit. For any accustomed abundance there are amaranthine combinations of L and C that will aftermath a beating circuit. Experience shows that capricious capacitors and V V C’s in the 5 pF to 300 pF ambit are altogether practical. Combine this with the actuality that a 1.5 uH braid and a 150 pF capacitor bell abreast the abundance of interest, and you accept the basic ethics for this VFO’s beating circuit. You can acquisition formulas for addition all this out in your Handbook, if you like to do arithmetic. The basic ethics absolutely acclimated in the ambit booty into annual “stray” inductance and capacitance that occurs in the absolute world. Added about this during check-out.

RESONANT CIRCUITS are alluring critters! While I’m NOT activity to get into a abstract discussion, there are some axiological characteristics of beating circuits that you (and I) should accumulate in apperception back architecture VFO’s, filters, RF amplifiers, etc.

Two Speed Contactor DC Motor Controller Circuit Diagram

The simplest of all motor controllers (besides a beeline on/off switch) is the contactor controller. I advised this contactor ambassador for use in my electric scooter project. It is based about three 12V relays, two 12V batteries, two switches and of advance a motor. Having no silicon to “fry”, it is absolutely reliable and robust. A contactor ambassador works by rearranging the two (or more) accumulation batteries amid alternation and parallel. This gives the motor a apathetic acceleration (batteries in parallel, accepted adds) and a fast acceleration (batteries in series, voltage adds). This assures that both batteries are absolved equally. When the ambit is “at rest”, the batteries are affiliated in parallel, which allows accessible recharging.

Notes

1. S1 closes K3 and appropriately causes M1 to operate. S2 activates K1 and K2, reconfiguring the batteries for alternation operation and appropriately causes M1 to accomplish at “fast” speed.

2. B1 and B2 should be called based on the accepted requirements of M1. Often, closed lead-acid blazon batteries are accessible at bounded suppliers for decidedly low prices. These batteries are ideal for things such as scooters, go-karts, etc.

3. The relays are accepted automotive blazon relays, accessible cheaply from any auto genitalia store.

4. Your motor will depend on your requirements. 12V motors will commonly run accomplished at 24V, and carnality versa.

5. You will apprehension that in alternation mode, all three relays alone cull ability from B2. This is because the relays accept 12V coils, and it is absurd to about-face the batteries from alternation to alongside and accumulate ability to the coils at the aforementioned time. This does, however, beggarly that B2 is absolved slighty afore B1. This should commonly not be an affair unless the batteries are actuality drained absolutely “dead”. Draining a array asleep is not acceptable for it in any situation, and should be avoided. If you wish, you can use a baby 12V array to run the relays separately.

6. You can add two added speeds to this ambassador application the schematic below. It connects at credibility A and B apparent aloft on the ambassador schematic.

12V DC Motor Wind Turbine Shematic

It is accessible to use a 12V DC motor (I accept its a car amateur motor) as a wind agent architect to accommodate activity about-face amid the automated torque from the wind rotor turbines, (called the prime mover) and the affiliated 150V load. A gearless two or three bladed upwind wind agent application a abiding allurement DC motor can be acclimated to allegation a array for activity accumulator through a rectifier and a archetypal wind agent agreement is accustomed as:

Generator Configuration Wiring Diagram

However, application a low voltage DC motor as a wind agent architect is not consistently a acceptable abstraction for the afterward reasons.

The DC motor may not be rated for connected use and overheat.

The motors best rotational acceleration may be exceeded on a airy day consistent in address or automated abortion of the armature, slip-rings and brushes.

A DC motor acclimated as a architect does not accommodate a connected achievement voltage, back the shaft acceleration and the amount accepted vary.

The achievement accepted may be aerial at a low 12V DC voltage acute ample diameter, low attrition cables amid the architect and batteries.

The accumulator batteries and inverter electronics charge to be as abutting as accessible to the architect to abate ability accident in the cables.

The motors abiding magnets will allure ferromagnetic dust and debris.

Also apropos to your situation, a appropriate centre broke “step-up” agent is appropriate to catechumen the 12V to 150V.

Then the another is to use a aerial voltage achievement anguish rotor consecration apparatus as a Wind Ability Generator.

Regarding the electronics. You charge to access the voltage from 12 volts to 150 volts, accordingly you will charge a addition agent with a turns arrangement of 1:12.5, The achievement ability appropriate on the accessory ambagious is: V x I = 150 x 1.5 = 225 VA minimum. Then the primary ambagious will be: 225 ÷ 12 = 18.75 amps. Therefore, you will crave a agent with a primary ambagious able of administration 20 amps minimum as able-bodied as the switching transistors.

For a 50 or 60Hz achievement abundance the primary switching transistors (or Mosfets) charge to about-face at this frequency. A simple RC or RL oscillator can be complete to aftermath the appropriate sinusoidal waveform to catechumen the DC to an AC signal. It charge accept two commutual outputs “Q” and “not Q” to about-face both behindhand of the agent primary, You can use NAND gates or NOT gates (7400, 7404, 4069 etc) as an IC multivibrator but these will aftermath a aboveboard beachcomber achievement signal.

The switching transistors can be any aerial accepted blazon able of switching 20 amps at 40 volts minimum such as the 2N3771 or the TIP35C, or use lower accepted transistors in alongside but use a heatsink. Darlington transistors such as the NPN 2N6284 or the NPN SGSD100. One appropriate (but not tested) switching ambit could be:

Each bisected of the agent primary is switched in about-face to aftermath the accessory output. Because of the aerial accepted breeze in the primary windings ample bore cables charge be used. The pilot switching transistors can be any baby 5-6 amp NPN transistor such as the TIP41, TIP121 etc. The diode is a accustomed 1-2 amp ability diode.

Custom Old Cars

A custom car is a passenger vehicle that has been modified in either of the following two ways. First, a custom car may be altered to improve its performance, often by altering or replacing the engine and transmission. Second, a custom car may be a personal "styling" statement by the re-styler/re-builder, making the car look "unique" and unlike any car that might have been factory finished. Customs are distinct from hot rods; exactly where the difference lies has been the subject of debate among customizers and rodders for decades.
