clem! Posted August 8, 2009 Report Share Posted August 8, 2009 (edited) Hi all, I´ve had my hands on 3 SIDS 6581R4AR, so I had no choice but to built  my first MB-SID. Bankstick, encoders etc. may perhaps come later. Here are some pics: Best regards clem! Edited December 9, 2009 by clem! Quote Link to comment Share on other sites More sharing options...
M.U.L.E. Posted August 8, 2009 Report Share Posted August 8, 2009 Awesome! I have one 6581 r4ar, a bit different sound from the standard 6581. But strangely just about every one of my 6581 sound different (or not so strange as i've been reading) Nice workHey I have that same Korg keyboard, some crazy FM sounds out of that. I forget the model number of that - I dropped it unloading after a show and broke several keys and the casing, then decided to take the entire keyboard off it and mount the boards into a small rackmount. :) Quote Link to comment Share on other sites More sharing options...
Matrix12x Posted August 8, 2009 Report Share Posted August 8, 2009 great work.The first one was even lower budget than this. ;-) Quote Link to comment Share on other sites More sharing options...
TK. Posted August 8, 2009 Report Share Posted August 8, 2009 Great selfmade case and PCBs (?) :)What kind of encoder are you using? I never saw an encoder in such a white plastic package before.Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
nILS Posted August 9, 2009 Report Share Posted August 9, 2009 I like the casework - seems to follow the same principles of the PAIA Fatman - wood cheeks are always nice ;) Quote Link to comment Share on other sites More sharing options...
clem! Posted August 9, 2009 Author Report Share Posted August 9, 2009 Thanks for the repliesforget the model number of that it´s a kOrg 707, it was my first midificated-synth and costs me 800 DM has some great FM sounds - I like the brassy ones - very special!What kind of encoder don´t know it´s out of an ADD-two, twenty years old - maybe it is Densitron or s.t. like that, thank you very much for your great work TK. The case is selfmade - out of 1 mm aluminium-panel-sheet (I think 1,5 mm would be better, maybe next time). PCBs are fom Mike.wood cheeks are always nice of course, in this case they are a little bit to slim, but I will change that with the full control panel.The SID sounds better than I thought - never had a C64 by myself, I started with an Atari ST 1040.Now I will test the Bankstick ;-)Best regards and thanks for the great work here clem!

DrBunsen Posted August 9, 2009 Report Share Posted August 9, 2009 Excellent! Just because you're budget, doesn't mean you can't have wood 8) Quote Link to comment Share on other sites More sharing options...
clem! Posted August 10, 2009 Author Report Share Posted August 10, 2009 In some building centres you don´t need to pay for wooden rests - you find them in the grabberbox. :DBut my sid has an achilles´ heel - the two wallmount PSUs make problems to upload a firmware because of the power consumption - I allways had to pull the 4x20 lcd.Now I switched of the light. :-[ In the final version with knobs I will use a stabilized PSU of an external harddrive I think - this will be more stable.Best regardsclem!

clem! Posted August 12, 2009 Author Report Share Posted August 12, 2009 (edited) Hi there, some bad news from my MB. Now it smells a little bit strong - and it doesn´t come from the pots ;) - coz one elko from the sidboards lifts up - hope the sid wasn´t hurt  >:( Who´s got experience with s.t. like that? Do I need to exchange more than the elkos. I´m no electronic engineer. Best regards clem! it´s a 16V one!!! Edited December 9, 2009 by clem!

TheAncientOne Posted August 13, 2009 Report Share Posted August 13, 2009 You've either put the elco the wrong way around (reverse polarised it), or you may have a rectifier problem that is putting AC on the cap. Either way, you must replace it - it won't be safe after that swelling.Best bet is to take the chips out, replace the cap, check the rectifier position, and check to make sure there isn't a shorted diode in the rectifier, or a solder bridge, then power up and test for the right regulated voltage with no chips before re-installing.If it's the right way around, and the rectifier is working fine, the you may just have had a bad capacitor.

Smithy Posted August 13, 2009 Report Share Posted August 13, 2009 Is an Elco an electrolytic capacitor?It took me ages to figure that out, if its even right that is! Quote Link to comment Share on other sites More sharing options...
avogra Posted August 13, 2009 Report Share Posted August 13, 2009 an error there could also explain, why the PSUs dont like you ;) Quote Link to comment Share on other sites More sharing options...
TheAncientOne Posted August 13, 2009 Report Share Posted August 13, 2009 Is an Elco an electrolytic capacitor?It took me ages to figure that out, if its even right that is!Yes it is: can be 'slang spelled' as 'ElCo', or 'Elko' or sometimes 'ElCap'. I tend to use the longer name of 'electrolytic', usually. I think ElKo is the German short name - they spell 'Kondensator', but German technical names always sound the most impressive anyway.

clem! Posted August 13, 2009 Author Report Share Posted August 13, 2009 the sid-board works again after changing the electrolytic capacitator (sorry for the unenglish spelling - elko - when I wrote it I didn´t realized that it´s a German expression).I´ve changed them from both SIDs eventually those 2200µF 16V ELKOs elcaps I had in the kit aren´t the best choice.

clem! Posted September 24, 2009 Author Report Share Posted September 24, 2009 (edited) Some pics of the second level: sid cs and kb-housing - for controller-fun I will add a joystick and a sharp ir-sensor ;-) the parts are completed now - so I´ll hope this weekend there will be s.t. more to see.

clem! Posted September 29, 2009 Author Report Share Posted September 29, 2009 (edited) mmh, that´s bad - had not enough time this weekend only soldererd encoders, switches and LEDs on the board. But here you can see a construction pic. Think the joystick will only fit below the matrix. I´ve paid only 2 EUR for the wood but because of the cs this won´t be a low-budget-mb anymore. clem!

Labelwhore Posted September 29, 2009 Report Share Posted September 29, 2009 That case (the wood and stain, not the shape) looks really similar to what I chose for my Paia fatman. Nice choice! Quote Link to comment Share on other sites More sharing options...
