[my midibox sid freeze on startup when the din modules are connected]

i tried but i can't make a decent picture with my crappy camera .

i'll try to borrow one .

i rechecked the module and resoldered everything on it but without succes

[my midibox sid freeze on startup when the din modules are connected]

thanks i think i understand better now

i retried but the results seems weird

with everything connected (4cores+lcd+complete control surface) i get 0,33

with everything connected except the dout modules i get 0,07

with everything connected except the dinmodules i get 0,07

with everything connected except the LCD i get 0,14

sometime it boot normally after i made a "shortcut" with my finger .

Where?

the j1 connector on the first dout module

[my midibox sid freeze on startup when the din modules are connected]

it's fully working when i disconect/reconect the dins or dout .

sometime it boot normally after i made a "shortcut" with my finger .

if i don't solve the problem i'm gonna add a switch but i hate to solve a prblem this way

i tried to do what you said but i get a static 21 ma wich make me think i'm doin it wrong .

what do you mean by "bridge" ?

this is very frustrating i have a fully working sidbox that crash on startup .

thanks for helping

nobody ever had the same problem ?

hi

i'm not sure i understand the question .

i allready mesured the current on the core ic1 like you told me and i had

C1:MCLR(1) - IC1:Vss(12) = 4,6v

IC1:Vdd(11) - IC1:Vss(12) = 4,6v

IC1:Vdd(32) - IC1:Vss(31) = 4,6v

where am i suppose to mesure the current now ?

i tried without backlight and without the slave core modules but i had the same result.

i'm using the c64 psu with http://www.ucapps.de/mbhp/mbhp_4xsid_c64_psu_optimized.pdf

i checked all the soldering and it looks clean

thanks for helping

that sucks

i have that problem again !

everytime i power the unit up the lcd show a blackrow .

but if i disconnect/reconnect the din or dout my midibox boot normally

C1:MCLR(1) - IC1:Vss(12) = 4,6v

IC1:Vdd(11) - IC1:Vss(12) = 4,6v

IC1:Vdd(32) - IC1:Vss(31) = 4,6v

[my midibox is alive]

hi

my midibox is nearly finished (but it's already working fine)

i started a popcorn remix to try that beast and it's a lot of fun !

i tought i'd share my joy with you all cause those kind of topic helped me a lot when i started this project .

i know the design is far from original but here's a few pictures http://www.slide.com/r/xla54bzv7j8c1D1wpo3n5WRoPixrDmDE?previous_view=mscd_embedded_url&view=original

i'd like to thanks Mr Thorsten Klose for this fantastic and really well documented project and everybody on this forum (nearly all the questions i had were already answered)

edit: it's a 4x6581 midibox sid with complete control surface with 8 banksticks

thanks for helping midiboxxer !

i resoldered a few cables on the power supply i made months ago and it worked perfectly .

now i only have to make holes in the enclosure ( a c64 box ) for the plugs and my sidbox is finished .

but it's alive already !

[my midibox sid freeze on startup when the din modules are connected]

i have no idea why  but it's working normally now !!!

[my midibox sid freeze on startup when the din modules are connected]

C1:MCLR(1) - IC1:Vss(12) = 0,9v ??? c1 is the capacitor right ? what is MCLR ?

IC1:Vdd(11) - IC1:Vss(12) = 4,6v

IC1:Vdd(32) - IC1:Vss(31) = 4,6v

sc-j10 is not connected

r1 is 100 ohm

thanks a lot for helping

hi thanks for the quick answer

i use the c64 optimized psu http://www.ucapps.de/mbhp/mbhp_4xsid_c64_psu_optimized.pdf

[my midibox sid freeze on startup when the din modules are connected]

hi everybody

i just finished my midibox sid (4sid) with complete control surface and everything is working normally .

the only problem i have is that it freeze on startup when the din modules are connected ( the lcd show a black row on the upper part )

if i disconnect/reconnect the din modules everythying work normally .

i soldered all the resistor and the unused chips are not stuffed on the last din .

if someone has an idea of what's wrong that would make my day

thanks in advance

ps: it's a v1 midibox sid
