  3. Panning Stereo Mixer for 4xSID + Headphone out

    in Design Concepts

    Posted

    So here a design for a panning mono to stereo mixer intended for a 4xSID box based on the TL084.  It is pretty much an duplicate of Ray Wilsons MFOS

    (http://www.musicfromouterspace.com) mixer with the addition of normally closed mono jacks to steal the mono outputs from the stereo mix when a cable is connected.  Each channel has its own level and pan controls and the whole deal is driven with +/- 12VDC.

    I will be building the prototype in the next couple of days so I should have brd's/partlists available shortly.  Any comments are welcome.

    Cheers.

  11. SmashTV LCD brightness

    thanks smash.

    Mine is really low (you can barely see that it is on with normal room lighting) so dont think i'm trying to push it too bright.

    Here is the thing though, i am using R3 boards. Is the trimpot functionality the same? For some reason, I thought that one pot was for normal LCD contrast and the other one was for the backwards ones.  I tried 2 types of LCDs on two of my cores and neither pots affect the brightness

    So far i have done only a coffee cup (turned out great) and a some test text on the back of an enclosure that was close in color to the panel I am working on.  I unfortunately sprayed the panel with not clear but tsn so it didnt turn out that well.  I will post my real results when i get the artwork done.

    search the forums, there are a couple of ppl which have posted their results

    I'm planning you use a "liquid glass" coating called Vitrail which is used for Glass and Cermamics as well as usable on metal.

    Bear in mind that they recommend you use a spirit based clear coat (Polyurathane is one) water based ones will leave the backing white.  I'm really happy with the results and cant wait to start on the FP for my 4xSID.

    I have been hearing about this stuff from several sources (including some ppl have used it here) so I decided to give it a whirl.

    Well IMHO, this stuff is the best thing since sliced bread.  Simply print at highest possible resolution with inkjet or color laser, let it dry for 30 minutes, cut out, soak in water for 60 sec and you have a  fairly thick, very handling friendly decal.  I was easily able to transfer on a textured, powdercoated aluminum panel.  You finish it with a solvent based clear coat which makes the white background clear. The results are pretty spectacular and the idea of ever getting anything screened again is totally out of the question.

    The drawbacks that I can see is that there is no white in most printers, but the white backing can remain opaque by using a water based clear coat and I guess you could do a combination of both is  u mask out whatever you want to have white in it.

    at 16$ for a 10 pack of A size, this stuff is worth checking out

    but there is a definate high pitched digital type noise in te background which seems to change depending on which patch program you are using

    Did you remember to add the 2200 uf/16V cap to the end of your power chain? I have the 4 sid running and it is super quiet so sounds like you did not add it. Also short the audio input (J4 on the sid)
