My 6-channel USB remote-controllable relay card.

[scientistmaster1]

may I have the schematics, the layout and the name of the components?

The software also works on windows? I saw also the ultimate but i'm a beginner and I prefer this one...

Did you used two 7segment displays or a double one? because I have a double one. Thanks!!!

[bluebird1422]

how about sharing this stuff on CC license? :)

[darkopungercar]

Please send me the technical details for construction are USB relay card to mail darko.pungercar@gmail.com

[MtroCesar]

1 question how can I check the functioning of the pic? I already constructed it but it does not work

[dzverche]

woops.. and where can I see schematics? can you please send me the address of your homepage? thanks.

[dzverche]

amazing work brother, i don't know why but the first time I saw your device the first thing in my mind was "atomic power trigger" :D

[xikesxikes]

cool project! I was looking for a schematic to build my own USB relay.

[mustafamahameed]

great !!!!! thank you

[SaschaHeylik]

Hey, I need a cheap and easy way to control some relais from linux through usb so i can control the lights and alarms in my room. Can you help me?

[linuxgeek81]

@SaschaHeylik You could build yourself this card, for example ;) All you need can be found on my homepage.

[SaschaHeylik]

@linuxgeek81 How much do the components run you without the display and stuff? i just wanna control relais with my server. Or, could you make me one? I am from austria. Actually i could talk to you in german...

[D0senpf4nd]

hi, could you post a link to the wallpaper you have there? its very cool :)

ah, and cool video :)

[louischoo72]

i like you ideas................

1st usb control, 2nd timer control & 3rd remote control. really amazing.........

[linuxgeek81]

@louischoo72 If I find the time to realize the second version it'll have even more sophisticated features than those. This was one of my first AVR based projects and I figured I can do a lot better in the meantime.

[louischoo72]

wow ! i like this project.

[linuxgeek81]

@louischoo72 I'm currently working on a successor to this card. Don't know however how long it may take to realize it, it's quite heavy ;)

[karlwatkinslopez]

hi Michael , I'm a fan of linux (debian) and I am interested in your project 6-channel USB remote-controllable relay card, I printed my plate (PCB) with UV insolated unit and bought several devices , but I could not find in Chile the relays ( F4052 ) and Photo Modules (TSOP1736TB1) and other devices. Can you help me find them? . I leave a message on your page also. Thanks . Karl Watkins - Electronic civil engineer -

[Fearlessleader90]

Impressive card, lots of practical applications. Although I must ask you, What system monitor are you using on your desktop? I must say It's rather sexy.

[linuxgeek81]

@Fearlessleader90 Thanks. It's still my LG Flatron L227WT, superceeded by newer models in the meantime.

[Fearlessleader90]

@linuxgeek81 I'm talking about your performance monitoring tool... Is it some form of a conky configuration?

[linuxgeek81]

@Fearlessleader90 Oh right well this is an older (quite old) tweak with a software I wrote myself. Would require some polishing, specially the transition to USB. Where did you see it in the video anyways?

[Fearlessleader90]

@linuxgeek81 It's sprinkled all over the video, like @ :25 for example up in the left hand corner with the spinning cube. and other charts (I'd assume for ram usage / network utilization etc.)

[justerinmg]

wonder if this software would work under freebsd

[jihad355]

you can control it by internet from outside home ?

[linuxgeek81]

@jihad355 Sure, as long as you got some net connection to the machine it is connected to, for example via SSH.

[engago16]

this question might be lil humble for u but plz concern answering me (how could u program the AVR by the usb without using a usb programmer? i have alot problems controlling the USB if u could help me ill be great-full )

[sparky3489]

Curious to know why you didn't use opto-couplers/triacs? Relays are too noisy.

Also, could you fix your site so the SCH and BRD files are obtainable? Even if one tries to select the text, the ROW numbers get selected as well which results in corrupted files.

[linuxgeek81]

@sparky3489 As a matter of fact, I like to hear it switching, since it notifies you about the event you just triggered. I guess you meant solid state relays as an alternative, those are very expensive, though. I wanted this to be a budget thing. Greets, Michael.

[sparky3489]

@linuxgeek81 LEDs also make a good indicator. Solid state relays are expensive but optocouplers and triacs costs about the same as those relays and don't create electrical noise. I sent you a link to an example.

[linuxgeek81]

@sparky3489 It doesn't provide the same electrical characteristics. It would be a different approach. The electrical noise is being supressed by diodes. If you want to build it like that, I certainly won't keep you from doing so.

[sparky3489]

@linuxgeek81 Your right, a triac can handle much more current. The traics I'm using can handle up to 12 amps but I have them fused to about 3 amps each.

I'm not talking about induction from the coil, I'm talking about switch bounce.

[linuxgeek81]

@sparky3489 What are you trying to tell me. Seems to me that you want me to acknowledge that you did the better thing. For you this may even be true. But I don't care about it, so don't push it.

[sparky3489]

@linuxgeek81 No need to go on the defensive. I'm not trying to "out do" you. I'm just asking because I'm always interested in other peoples approach to electronics. In fact, I'm very interested in the USB aspect of your design as I'm wanting to go that route.

I too have the STK500 and would like to use an AVR. I would very much like to have your Eagle files if you can get them to me.

Again sorry for the confusion, I didn't mean to offend and I'm sorry if I have.

[Minifig666]

@sparky3489 The clack of a relay I find is quite satisfying, like a well built toggle switch! Also these particular relays (Finder 40.52 series, if I'm not mistaken) are well built and are very cheap to replace. (£1.70 for me) Relays are also much more tolerant to all sorts of things! Why I'd use them!

[sparky3489]

@Minifig666 I don't begrudge your use of them. My points for triacs are they have a smaller footprint, can handle much higher currents, do not require a diode to prevent backfeed induction, come in latching or non-latching varieties, don't suffer from switch bounce, don't suffer from dirty contacts (carbon build up from arcing), don't need replacing and they're quiet.

Relays can be multi-poled and don't need heat sinks.

[linuxgeek81]

Please stop messaging me about the schematic, it's all located in the repository accassible on my homepage, like all the other projects. Thanks ;)

[jonsadj7]

Dude that is wikid!!!!

How much did it cost you to make it?

[linuxgeek81]

@jonsadj7 Cost of what? Time, money? Preperation? ;) Thanks anyways, glad to be such a wicked little guy, hm? (=

[rlnilson]

If I could devote all of my time to stuff like this, I would. Immediately. Or, maybe in ten minutes or so.

But srsly, very cool.

[cprALexe]

русский? :)

[Aadbuild]

hey could you put me onto a book that will help me get up to speed with this type of thing?

I would like to automate my home... I see big possibilities

[Robosos]

is it not dangerous to experimentate with 230V?

[linuxgeek81]

It is, that's why I don't switch more than 12V with that card ;)

[modalen2]

@Robosos if you use another relay after the smal relay then you kan contol 1000v if you want

[Wwallace67]

Could somebody add subtitles? LOL. Just kidding. Good job on the electronics.

[punisher129]

Nice work. I am wondering what is that USB connector on the board for, I mean how do you communicate with the pc... serial to usb with some ftdi chip? I have no idea how to use the usb port under linux is it easy?

[CrzayZakster]

can i have the Schematics, PCB layout, firmware and software please. thanks

[djomar1987]

i need 50 relay bord

[shadowlord325]

Can you make custom timings for a relay (e.g. coded signals)?

[linuxgeek81]

Not with that firmware but in principle it is possible, of course.

[TheSimonTsai]

It looks great!

Please kindly email me the schematic and layout.

Thanks very much in advance.

Best Wishes.

Simon

[linuxgeek81]

I will not mail my projects around. They can be found on my new homepage for download.

[linuxgeek81]

Please visit my new homepage. There you'll find information about how to obtain the project.

[hansnielsen1989]

Hello, Michael

where you bought it or did you make it yourself?

And if you bought it you can not send me a link hope to hear from you .. Greetings from hansnielsen1989

[josephdzn]

Hi michael,

Awsome board you got there!

Can i get the sch/brd of this? i want to implement this in my room! lol

[nycpntr]

do you make your own pcbs?

[linuxgeek81]

Yes, I make these PCBs myself (photo positive method).

[loopycoaster]

i have hardware: an usb relay card from robot electronics. could you please give the code of steering the relay card with the pc (the basic steering and timer), or isn't it going to work with other relay cards?? ty and srry for bad english

[linuxgeek81]

Sorry, that would be pointless. You'd need a software that uses the protocol of that specific card. But I suppose such software is available...?

[loopycoaster]

or the code off course v_v

[linuxgeek81]

I wrote everything myself ;) The software wouldn't help you much without the hardware, though.

[loopycoaster]

which program do you use? i wanna use it too :)

[bluetorch13]

just... WOW! very nice work! I'm planing on doing one of those since I was 14! ... I'm 28 and still planing... lol

I will buy one, I just want to focus on the User Interface (Flash for sure) and a touch screen monitor. : D

I'll let you know if I have a question : P

[linuxgeek81]

It's not that hard... but granted it needs time to get into.

[arg13415]

Can I have a copy of the schematics and everything?

[vikalpchaudhary]

hi

do u have the schematic and all the rest ?

[mikemcdonald113]

How did you do the remote? I am creating something similar, and I want to know how to do remote control using a standard remote, thanks.

[linuxgeek81]

I use an RC5 remote.

[HLSDK]

Thanks for the new videos, Happy new year!

[JulianSurf3rPR]

beautiful.

[linuxgeek81]

thanks

[adam859]

thats awesome, what do all the lights control, i noticed you didnt turn off the last 2 what are they for?

[linuxgeek81]

Thanks ;) The both switched on relays are for the light and my stereo.

[djdevil360]

hey u done a vid on it =]

[linuxgeek81]

I think someone requested it...
