This what i'm gettin intermitant of the timeout msg...very intermitant tho... [i.1] N 4.F | 0_ ------- 4.E | 0_ that useful for nethin? Cheers

yup, 1k resistor is def properly connected

yep - all 32 pots to the AIN test good (values frm 0-127, no jitter) when i test with the AIN test f/w. Likewise with the DIN Button test f/w - 8 buttons all good (on DINX4 - 1st IC mounted, rest left empty but with 10k pullups)... time for the midiman himself to enter then i guess - Thorsten... lazy-eyed newb in distress over ere mate, pls elp :P Peace... Dan

o plus, i'm on a always-on-ADSL connex, so i tend to leave this site on my 2nd monitor - since I'm askin q's every 5mins :P so thats y my nik is here alot peace D

lol ian... ;D I was aiming for a few hrs but I just wanted to get this box out the way - I finally got the pots and buttons workin today/yesterday (what day is it :p) and this error message wouldnt leave my mind! I've put so much into these projects I have no option but to get them finished...which i want to do neways ;) I've havnt even made a track in months as the aim of it all was to invest the time gettin the studio setup exactly how i wanted it - hence all these midi boxes... I'm in England btw...

yeah, as well as v1.01 I also tried v1 of the mb64 f/w and also the mbseq f/w - still get the same midi time out msg right after the boot/f/w version screen :/

replaced xtal just to make sure - still the same time out msg as before :(

hi ian, yeh I saw that most too on whilst looking to see if any other users had this prob... the xtal i'm using is 20mhz bang on (ordered from reichfelt using T's order list to make sure it would be the right one). Mebbe i should try replacing it - but wudnt i get the same midi timeout error when runnin the AIN and DIN test f/w's if it was the xtal? As i said, when using the AIN/DIN test f/w's midi output if fine and stable... Hmmmm Cheers... Dan

still no developments...:( just to make sure - i'm using a dinx4 but with only 8 buttons on this box. buttons are connected to the first IC (other sockets left unstuffed but with 10k pullup resistors) - 4 buttons go to din J3, and the other 4 to din J4 - the gnd of all 8 to Vs on J3.... again with the din test f/w the buttons worked fine... even tried a new pic - still gettin the message :( what could it be?

midi does seem to be cool tho, i burnt the ain test again and it's outputting correctly knob 1 gives out cc values (0-127) on cc64, knob2 cc65, knob3 cc66 etc... so if midi appears okay with this test f/w what else could be the prob? what should the lcd display after u burn the mb64 f/w (after the boot-up f/w msg)? :/ cheers Dan

midi time-out displays with no midi connected and with either midi in or out connected - dont matter, still displays it right after f/w screen.... rogic - that midi mon is from scope, i'm using a pulsar2... cheers.... Dan

okay, added the 32 pots and 8 buttons (both test f/w's successful) and then burnt the latest MB64 f/w, turned power on and I got a 'MIDI time-out! - What's Up ???' msg after the intial intro screen confirming f/w present...this is what was coming out the midi out port: replaced the 6n138 - made no diff... is this a connection problem? I notcied the LCD also printed this, intermittent of the midi time-out msg: [i.1] N 4.5 0_ ________ 0_ Itallic = guess at number - pixels were broken up... Stumped...:( again... Dan

;D well, i did what i dun last time i had probs - soldered direct to the pins rather than using header sockets - and hey presto, working pots! still not quite right but most pots are now working and showing the correct pot number and value! pics of this1 comin soon! Nice D

Ye Ian they are 10k Lin pots - with the dmm on the outside pins they measure just over 10k. With the knob in the middle and the dmm on pin 1/2 or 2/3 the pot measures just over 5k so they are the ones... prolly a connection on the AIN or core - but i dont know :( driving me nuts tho - really need to get this sorted...a midibox without knobs is like a car without wheels... peace

Lo peeps... well before i get rollin with my big boxes i thought i'd do a lil trial box based on 32 pots and 8 buttons with an LCD to top it off... I wired the pots according to the walkthrough, cabled the unused pins of J5 on the core to gnd and burnt the PIC with the AIN test f/w... Turned on the box which booted with the AIN TEST msg and then after breifly displaying a cpl of values it goes to: Pot: #-- Value: -- Okay, good so far - no random values/jittering etc. But thats as good as it gets... most of the pots when moved dont display any info on the LCD, and the few that do give random pot/values - even when only one pot is moved :( I've re-soldered the pots 3 times - but each time i get the same result - which makes me think: 1. My pots are not standard, mebbe the pin that goes to the IC is one of the outer pins? - But then why would some pots send info (even tho it's screwed info)... 2. Problem with the AIN module it's self - Dunno how to test if this is the case - cudnt see ne info on the site to test the AIN... 3. Problem with the core module - which tests good... I'm stumped and losing hair! Help! Best Dan

amazing work T ;) i'll need to dust off and brush up on the programming skillz now :o - another century of q's to follow no doubt...;) bring forth the 18F yeeeeeooooooowwweweee!!! peace.... Dan

I think a switching psu needs a load before it'll run, and as the mbhp stuff doesnt require that much juice it's prolly not the way to go... unless u stick a lamp or summin on ya box....i could be wrong tho...

there are lots... Illustrator, Photoshop, Freehand will do all that with ease, but I'm sure there'll be a few freeware apps about too...

well, i was aiming to follow the guide as done on S.Thomas' site using decal paper. The type i got however wasnt the same one as when i popped it in the oven it didnt exactly go to plan :P, and there was no mention of using an oven or placing toner side down on the instructions... so i took a slighty diff route and printed on the decal paper mirrored, placing it toner side down on the panel, letting it dry out for a few hrs, then... (ahem) spraying the panal with a good few coats of flux spray... ::) tho, i wudda used spray vanish/laminate is it was about... neways, the final finish was pretty nice, was thinking of giving the top a light goin over with some fine steel wool to give it a more matt finish...but dont wanna rock this sid boat nemore atm...;) best...

I'm using a 15v 750ma wallplug (inline with a 1A fuse) to power both the core and sid, and hopefully another box...;) works fine here, sid does get a lil warm round the edges - but it does neways, i dont think u really need a fan and heatsink, the only thing i have a heatsink on is the 7805... hth Dan

Hi Ian... Good news about ur sid ;) gives me hope that the other core n sid i dun could breathe some sounds still - prolly just a dodgy connection as before... Dont give up hope on the lcd, i hard soldered mine this time (tinning the wires first) to the pins of the header and low n behold it worked ;)... Here's a few more pics of me SID with some top panel artwork added: http://www.notapplicable.co.uk/mbhp/MBSID_6581-4.jpg http://www.notapplicable.co.uk/mbhp/MBSID_6581-5.jpg Will do a 8580 version too...;) Peace Dan

does it matter? some1 new to EE and this homebru lark (like me), could post alot (again, like me :P) and become a full member or whatever the tag line is...even if they are still technically a newb (like me), doesn't mean they know any more/less than any1 else - it's just about how much you post, be it questions or answers, or whatever... anyway, the important stuff is the mbhp, not a ranking system to let everyone know how hot with a soldering iron u are... my 2 pence

and 1 of the back panel...;)

Decided to leave the LCD neways, was a bit of a squeeze in the lil enclosure I'm using and besides, the ltc makes up for it ;) Here are some early pic's of it... I'll be adding some artwork later today (using decal paper).... Apologies for the moody pic quality - only using a cheapo digicam.... Loverly Dan

yup, just use a 10mhz xtal with the new pic, I believe all the other modules are 1:1 compatible too, and the JDM can also be used to program the new pic too! HTH... Dan
