  1. Ah I have to say this is my first double side PCB I made, so forgive any faults... ;)
  2. Gi Hero999, Hehehe, there are 2 break tracks... one top and one bottom... ;D it's anxiety, but its fixed. I thought that nobody will notice... The tracks without a destination you have to ask to RedWire... I only change the bottom area for the ground... Thanks for comment. Audioguru, the Ivan comment are in the bottom of the link of the project... Do you see?

  4. Hi, Can Audioguru comment the modifications suggested from Ivan in the main page os the original project? I would know if I can upgrade my original project and and make it great without change the PCB. I'll change some resistors Watts too. Please help here AudioGuru. Thanks a lot. Best Regards.
  5. Ops do you mean 0,27R 10W? Hehehe Audioguru can I use 2 0,47R 10W in paralel for R7? Its the more aproximately value I found (for the 5A or more layout).
  6. Hi RedWire, this is your double sided PCB made with the toner transfer method. Soon I will make your 5A PSU version. I build the original before I see this forum... Now I will upgrade to the 5A version with samples of TI. I'll post the progress...
  7. Because When I decide make this power supply the link to the forum doesnt work, so I make the PCB for the original version. Can I only change the components and increase the pcb traces? Or I have to make a new PCB? Is there any way to use a output of 0-15V 3A (or 5A)? Best Regards to all. Thanks for help.
  8. Hey RedWire, where is the zip file with all files of PS? :) I'll appreciate if you put the most recent files including the Eagle files too (.sch and .brd). The double side PCB is easy with the tonner transfer method. And thanks again for the support. Audioguru, thanks to you too. ... When I first saw this project the link for the forum doesn't work, so I make the PCB and search for the components for the original version. Now I will make the RedWire most up to date project. But my transformer (the only I have in the moment) is 24V 3A. I only need 0-15V in the output. I ask you if I can use the Redwire Project to obtain 0-15V in the output without any problems? Best Regard to all. Here some pictures of a case of my project.
  9. Have any chance to make the RedWire circuit mod work with 30A? Maybe change only the transformer (30Vx30A) and the retify diodes, number of power transistors and wire diameter? I suggest Redwire to put in the beginning of the topic the most recent files so that we don't need to seek for the whole topic that today is with 18 pages. Please include the Eagles files too (.sch and .brd)
  10. Thats because the a daughter card camera is connected to it. I've been reading more about this and the C6xx series aren't great for video decoding. Thats why I have decided on this, TMDSEVM355 has S-video / composite input and a RS232 UART output that I can interface easily. Thinking of getting this camera (didn't search much), http://bit.ly/ZpBuC , as it can be interfaced with the board easily, and is not to high in resolution 628x582px which means more processing can be done without fear of "time issues" Any comments, maybe I missed something somewhere. Thanks :D
  11. Hello, me again! Any ideas if it's possible to take the audio inputs and outputs of the TMS320C6713 DSK and use them to interface inputs/outputs from/to DSK and a PIC?
  12. Hey, Thank your professor for me, and thank you. I'm still studying my hardware options slowly getting somewhere. Will let you know what happens :)
  13. You know, because a blimp floating in the sky isn't unusual ;D. Then again if everyone has one.... I'm looking at all these processor boards, but realized there's one thing I don't know. What type of I/O connectors should I be looking for? Since it seems I have to get a camera separately from the board (couldn't find anything bundled so far), I would assume a USB connection for input, but what other "popular" options do I have besides USB (if the board doesn't support that). As for output, I've got no clue. I'm looking for something basic... that is I can send signals to certain ports on the board (similar to what the PIC does) but from what I've seen there are many standard connector types. It's overwhelming. PS: Going back to your original idea of having a micro PC, it seems weight is not an issue there, but what about power?
  14. Thanks for your help again, I'm really benefiting from it :) I didn't divulge fully the purpose of the project. The hardware is the bigger part of the project as the it is meant to work for different image processing algorithms, detecting various things (fire, people, license plates etc). So having "solid" working hardware is more important then the algorithm to detect the fire (which there is already much research on). Your embedded development platforms key word seems to hit the spot, I found the website http://www.sundance.com which seem to offer something I'm looking for. Things are starting to look up (for the time being)
  15. Hey Alex, Thanks for your post. The problems with getting a micro PC motherboard are two fold: The weight of the board + peripherals and the supply of power. I'm attempting a more DIY for two reasons, one its a university project, and two it will allow using bare essentials to conserver on power and weight because blimps are costly little buggers. Any ideas of manufacturers of DSP boards, or DSP capable boards (maybe FPGAs)? Regarding the transceivers, someone recommended this, http://bit.ly/5ZjIHv, which seems to be good when matched with a proper antenna. I've also already found a GPS chip that gives lat, long, time, alt, heading/direction. As for the issues I anticipate, they include more details of the connections and the possible use of PICs / arduinos to tie all the components together, and initialize other components. PS: I can attach the RX to a electric shocker on the fireman's ***, maybe that'll get them going :P Cheers
  16. Heya, Actually camera could be color / IR / thermal... It'll just change the algorithm used for detection :)
  17. I'm currently embarking upon a project that will allow me to attach a device onto a blimp for fire detection purposes. This device will have on it three major components, an image processing device, a communication link and GPS. Ultimately what I want to do is process images to detect if there is a fire, if there is one I want to send a flag + gps coordinates to the communication chip to be transmitted. I am having trouble finding a board ready for image processing, i.e. it comes bundled with a camera, or a camera can be interfaced easily. I want to be able to process images on the fly to detect whether there is a fire or not. I have found this http://bit.ly/5N3X7y board, and a corresponding daughter card (with camera), but the problem is that it there are no output links besides the analog headphone/line out, which makes interfacing with my communication device difficult. I'm also trying to find a RF transceiver that will work at distances of about 9-15Km, but the best I've found so far is this http://bit.ly/5Fdrxq. Speed is not a great issue as I'm only sending a few bytes of data. Can anyone give me some advice regarding hardware, and any potential pitfalls/problems that you forsee (that I have not). Your help is greatly appreciated :)
