NP SLP ;)

I tried to find 24LC512 and there is no any in Serbia (Not France) I found company that has them but they only sell to companies not individuals. I`ll see can I find somebody to buy them for me. Also I cannot find PIC18F4685 here. There is some Microchip distributors but I need to check the min. quantities. But that not worries me now, I don`t expect SID V2 any time soon. I think TK said something at the end of this year. I see he is progressing nicely but still I don`t expect it soon. Maybe I`ll find a way to get it till then. Anyway, I will ask for help if I fail. Sorry dj3nk, you must mixed me with somebody. I don`t live in France and I was never interested in C16, but thanks for an offer anyway ;)

I`m not sure I understan exactly what is confusing you, but there is only one ground! It doesn`t metter where you took ground from. I use to solder piece of wire directly on the closest PCB if I need it for buttons or LEDs or whatever... Only thing you have to know is that you need to ground all unused analog inputs to the ground no matter you are using muxed or unmuxed mode...

Sorry dj3nk, but I don`t quite understand what you saying...

I just got reply from EAO distributor, and minimum order is 100 pieces. 3,54 EUR/piece+ taxes/ handling and 80 EUR shipping from Croatia to Seriba (bordering countries)! Sooo, I`m still going to make my own buttons in future...

Some might find this converter useful http://bram.smartelectronix.com/plugins.php?id=15

I also sampled some MEC switches some time ago. They are all good quality but way too stiff and noisy for audio applications. I would expect them to be pricey too.

Is it necessary for you the buttons are printed? You can print the signs you like on transparent foil and insert them under the transparent window of something like MEC buttons (http://www.mec.dk) They appears white and can be illuminated with green LED.

That is nice to hear. Ill try to find some of 24LC512 then. :) Thanks Wilba, My home is always open for chip donors but, ...why don`t you need them? ...there is a lot of MB projects you can use them for. Or you have got more than I think :) Anyway, I`ve got only option to pay you using bank wire transfer (no pay-pall, sorry) so bank transfer fee cost more than those few dollars that I want to send you for shipping, so I`m still not sure can we do it easily. :-\ Anyway, thanks a lot for your offer ...appreciate it! ;)

I understood it is not supported by any application yet, and I didn`t wanted to buy it and wait for new application release to use it. Quoting TK: So, is this memory not supported at all, or not supported fully? This sounds little confusing to me. Gladly, but shipping from Australia would probably cost more than 7 x 24L256. Thanks anyway!

I bought one small 30x30mm fan for testing. It fits perfectly on 2 opposite places of face panel. But, I`m not sure can I feel comfortable with noise of those 2 small fans, even at lower throttle. :-\ I think I`ll buy one 40x40mm fans to check if it`s better to have one bigger than two small buzzers.. ::) ..must decide before I order some panels.

That UDN2981 is exactly what I needed! I`ll try to find it and I can use LM317 to set the brightness. Thanks alot Mike!

I have never used eBay before... Must check who will ship to Serbia. That is not always the case. I tried to hack LCD for red light but I failed.. First I tried do make new background LED illuminated diffusor which didn`t difuse well, and second try is just adding 3mm thick transparent red acrylic sheet on top of LCD. Result actually looks nice but dimmed. On picture looks better than in real because of higher ISO setting of my camera. At night it`s OK, but not by day - waaay too dimmed. I also tried transparent PVC sheets but les than 3 layers look more dark yellow than red and 3 sheets of PVC takes all the sharpness of characters... I gave up... ::)

Thank you guys for suggestions but I wasn`t detailed enough. Problem is the all LEDs share common ground with buttons otherwise would be easy to dim it. :-\ But i don`t believe this is going to be difficult to done by adding one more resistor at each out. I already prepared small PCB for resistors and headers. Trivial... I love the idea. Have you try it already? NP for off-topic, it is always happening here and there unintentionally. ;) NEWS: I`ve got one more floor finished, well almost... I need 24LC256 x 7 to complete it. New floor is piece of acrylic cut by HAND this time! ;D which is actually hanging platform for LTC and Bank Stick module. These days I will fill the rest of IC sockets. That is it for now.

Too bad but Wilba is right. I just found what TK said about LED dimming:

I am interested! So you can order only one LCD of same type? Can you order some other type then black on red? If not, I would go with what ever they have. I see they also have some PLED displays.

Thank you both. I `AM having fun... big time! I`ll post some more pictures when there be something new. For now here is the Endorphin by Night. After some playing with it I didn`t like how bright LEDs are. They are normal brightness, diffuse LEDs. It is nice to look at it from distance but not so nice to have it in front of your face, so I decided to add some extra resistors to equalize brightness of matrix (less bright - don`t hurt ayes) and rest of the LEDs. I will experiment tonight to see how close I can get.

I could`t wait to get back home to grab my SID again... and after some brick-digging I fixed the problem, and everything worked perfectly! I feel great relief finally when everything works OK :D Thank you Wilba once again. Enjoy you wonderful piece of work. All respect!!!

So you have 3 MLs and some of us none... life is just not fair. :'( Anyway, why is ML discontinued? I see x0xb0x uses some rare parts which I thought is only result to discontinue. cd_cd sorry for offtopic.

I never had any of edge-lit displays, but according to pictures they all looks like light is not spread well all over the background. Is it so obvious or it is how camera see it? It looks especially ugly on negative LCDs where background should be black. Is there something that could be done about it?

Wilba, thanks alot. I will do this as you explained as soon as I get home. One mistake that I realized now is when I changed ID with change_id application, I didnt upload the SID application again as I didnt receive proper upload request so I thought I cannot do that at all after I change ID and SID application must be already in it, but I was wrong... :-[

I will just say... :o

Comrades, I`m stuck at 98%! ::) Everything not working as it should. All modules individually tested before mounting to the sub-panel and they was working OK, but not together. I have done following: TAKE 1 1. burned bootstrap 1.9d 2. uploaded MIOS 1.9d 3. uploaded "setup_8580.asm" aplication with changed (and recompiled) #define DEFAULT_DEVICE_ID 0x00 for each of 3 slaves (0x00, 0x01, 0x02, 0x03) . Everything else left as it was. When Testing (link enabled) sounds are comming fom all SIDs but: 1. I can select patch and tweak parameters only on core module. 2. When I select the other SID, I cannot select patch nor tweak the parameters! (link enabled, CC disabled) 3. When activate both "Link and CC" buttons, I can tweak the parameters of all slave SIDs but still cannot load the patch into them. Its is strange as "CC" button should enable CC to be sent out (which is happening) and, as far as I know, they shouldn`t affect slave SIDs at all. Selecting multiple SIDs have no affection on the coresponding SID, only CC and link buttons made them read encoder tweaking. ...something is definitely wrong about addressing! ------------------------------------------ TAKE 2 I also tried to fix problem by doing following: 1. erased PICs 2. burned "bootstrap 1.9d" 3. uploaded "MIOS 1.9d" 4. uploaded unchanged "setup_8580.asm" to all PICs 5. changed ID with "change_id_v1_9c" application (I just uploaded precompiled files from device_id_00.hex to device_id_03.hex) The problem was: Only core working, slaves ignore "link" and "CC" buttons and stays silent. After this problems I decided to repeat "TAKE 1" as it is at least half-working setup. Again exactly same problem or same mistake. I really done my best several times and dont have a clue what is the problem. NOTE I`ve done uploading on each PIC using master module. This sinth is 98% finished and I`m stacked! :-\ Please, give me some advice.

No problem. I was newbie too, and still am for lots of things. There is always something new and interesting about you no nothing, so being newbie is unavoidable. ;)

...really no space. yeah... x0xb0x followed, but dont looks so cool as ML. ML came closest to TB of all 303 emulations - physically.
