Crazy Ass Veteran wants his free Subway!!! November 11, 2017 Veteran's Day Thank you for serving.
Drunk veteran is hungry and will not leave until he is served his free sandwich. He's not playing around. They gave him a free sandwich.

Opticom Emitter Arduino Prototype

This demonstrates how you can possibly build and encode an arduino capable of emitting 14Hz coded light signals used to change stop lights. These are known as Opticom Emitter.

These systems are more complex but still use the basic 14Hz flash pattern. With this being said there are periods where there is a off period then a constant on period. The timing I believe is still the same. TV remotes don't work for this system and neither does the mirt box that uses 555 timer chip. If you are serious you got to use a micro controller to flash white high intensity LED's. Once...

How you can fix this amplifier that has blown mosfets while your on a budget. Most of car amps have these blown on the power side or the output side which is known as the H Bridge. This amp has 6 N-Channel and 6 P-Channel. When MOSFETs blow, you have to replace them all with new ones that come from the same lot. These were IRF6215 and IRF3415 150Volt DS. The caps are 2700uF
Where can I buy the mosfet
Man that's a nasty amp..it's got Hella power..its got 2 transformers..lol..
Too bad you couldn't fix it
Thanks D 😊
maybe try something other than kinder-garden video
Do you find it convenient to use a tablet for ide? I'm attending to buy a s4 sassung tablet. Or do you think it's better to use a computer? I appreciate your help Thanks
Can you give me more info on this? I am interested in this.
where can i get one?
Thanks lots. :D
What is the value of diod ? 1001bd
hey was wondering where you guys get parts for the Rockford fosgate 1500bd my terminal part is broke I cannot tighten my power wire down anymore
Unfortunately when I transferred my PC to Mac laptop, I lost a lot of data due to incompatible XFS format of my drive.
Can you share the code please ? It would be fantastic ;)
Hi .. my project is Intelligent Transportation Systems so i want to add this project( opticom ) in mine using ardunio .. could you help me please
Hey i have a Rockford fosgate power 1500 bd it's a older one where can I get the board you got it blew cq 151 transistor q36
what is the interval between each group of 14hz flashes? 0.5 sec?
Love the "old school" amps from back in the day. Pity is now its much cheaper to buy a Chinese made amp than spend the time/$ repairing one. Myself.. I have several US made amps from the early 90s that are still working. I wonder how long the brands from China will last.
I was using a Rockford Fosgate The Punch HD150 amp from 1992 to power a pair of 12"s. It pushed 500+ watts into 1 ohm for nearly a year before I pushed it too far and partially blew up the rectifiers on at the power input stage. The amp was used in a boat throughout the 90s and thing left to rot until i got ahold of it 13 years later. Still worked like champ... until it literally almost killed me. When I pushed it too hard and put to much into its input something fried and high voltages (at least higher than 14.4V) at the amps switching frequency (>250KHz?) leaked into ground and caused the bass in my music to take control of my throttle position sensor and consequently my cars gas pedal while going down the road.... things got interesting at that point... When I got it home, pushing on the cone of the sub by hand would cause my cars idle RPMs to go up directly proportional to the position of the speaker cone. As if it were the throttle pedal. Playing music had the expected effect. Old school amps are fucking awesome.
I have this amp on my wall best and b4 died I have t2500bdcp it is dying making a noise from transformer and fat caps
Contact me about this
hey bro I have rf 1000.1bd that i need fix can you help me out basshead forever
Rare amp like that and you used IC caps? I don' get it.
I have this amp fix it please
I have a old school punch x360.2 have no sound one message are broken are this the problem
thank you I learned a lot:) I recently found out my speaker outputs are "blown" on my RF T1500-1bd. Do you have any pointers you can share with me friend ?
that's bull,they are terrible for chain reaction....
hi,will you pls let me know where i can order the mosfet for this amplifier(rockford fosgate 1000bd)pls..thank you...
bro I have the 1000.2 it has some small burnt things but it works not bridge tho
how would you do this with out a arduino uno because i dont have one is their a simpler way?
Have you progressed with this project? I would love to know what you used to time it
will you share the sketch for others to try?
Opticom has 10,000 possible codes, so you would need to do a similar frame by frame analysis for each area. Too many people figured out that you could build a simple 14 hz flasher with 555 chips, or even use some commercial strobe lights, and change traffic lights, so they started encoding them. I bought an Opticom receiver and phase selector off eBay for my traffic signal display in my basement, but I factory reset it to accept all or no codes so I can just build a simple 555 emitter to trigger it.
could you send me the signal
Would like more info on this project but RUclips's new PM system requires that your channel is associated with Google+. This very same idea has crossed my mind but I have never seen an implementation.
I have a punch 400a 4 channel plays but it get really hotter than normal, any idea what could cause that problem. It's used irf 540 transistor.
There are 4 Lil d Bios adustments under the hood on bottem of amp....see if there turned up?if so they need to be half way..a of them..
Ok thanks. Where do you get the mosfet to buy?
You sound like the blurred video, cant see anything No weed before starting
hola tengo una potencia sound magus me puede ayudar a repararla le borraron los codigos de los integrados operacional son de 8 pines cada uno si le mando fotos del circuito usted me sabra decir que integrados pueden ir?? le dejo mi email danielvillagra_13@hotmail.com
whats the correct name for the gain pot and the FZ pot or model numbers so i can find them.. mine are dirty need replaced..
And the power supply fets are ALL n channel if look they are labeled 'MTP75N05HD' 75 amp 50v rated mosfets.
Have you checked a lil chip labeled "tl702" it's kinda near the transformer it's a ic chip. Usually when the output blows up that chip will go too and leave the amp in protection. I had a bd500 that was stuck in protection I had to replace that chip
Where do you live? I first tried using a 555 timer to drive a high power transistor/IR Array. I had a multimeter monitoring the output frequency at both 10Hz and 14Hz and could capture the IR output with a camera. I had zero success. I also programmed a Arduino PRO Mini with the software used in this video and it did not work either. Right now, I am trying to develop a scheme that can go through all combinations of sequences, but having trouble trying to figure out the modulation.
Have you had any success at all?
Ok, I (think) have send you a pm with my email address. Thnx and Grtz. Henry.
Hi dbs2010, Could you please send me the programm/sketch for the arduino. I'm trying for so long now to get a similar project working, but with no succes. Thanks in advance! Grtz. Henry
Hey i could get one of those amps for 40 bucks is that good deal how much does it cost to repair it?
I would like to collaborate with you if you are interested. :)
Hi, can you please post your source for this? Thanks!
Nicely siad and thought thur.. just showing some of what works what is a plus to me.. Its nice to know what fets are working what and going what derection.. I got a BD1500.1 an see sparks going from a fet to a resister an the power supply makes a ring sound but works great.. where you think you can get the gain pots from?? mine are gruty sounding.
I'm sure it ha quit working by now. It sounds like a cold solder joint.
Who did you say you both the mosfets from?
Thanks for all the great info. What is the model of the meter that you got from HF?
