THANK YOU THANK YOU THANK YOU! Aris

Due to space constrains, I have to build a DOUTx1. Is there any schematics available somewhere? I have to build it on a bread board (like the DINx1). Thanks in advance!

Hi all. I recently gutted a Fischer-price Laughtop and I was thinking if I could use its keyboard (a 5x6 scan matrix keyboard without diodes) instead of hardwiring a DIN module input to each key. Is there some information regarding the use of such scan matrix keyboards where I could read how to take advantage of the build in keyboard? Photos follow.. Gutting here!!!

ΚαλημεÏα και σε σενα, Το PIC ID δεν Ï€Ïεπει να σε ανησυχει.. Δεν παιζει Ïολο στο τι θα φτιαξεις. Αν θες και εχεις ετοιμο το ενα CORE μποÏω να σου στειλω εγω ενα 4620 (Ï€Ïεπει να σιγουÏευτω οτι εχω βεβαια) Ï€Ïε-Ï€ÏογÏαμματισμενο. Απαξ και βαλεις το MIOS, μετα τα διαφοÏα υποπÏογÏαμματα, τα πεÏνας μεσω MIDI. Οποτε και αλλαγη να κανεις στον κωδικα του midibox και να εχεις καινουÏιο compiled hex, μεσω MIDI μποÏεις να το πεÏασεις. Η καλυτεÏη λυση βεβαια ειναι να παÏεις ενα Ï€ÏογÏαμματιστη για PIC. Eτσι, δεν θα σε νοιαζει τιποτε, κανεις compile αβεÏτα και δοκιμαζεις και οτι θες εσυ! Με το STM δεν εχω παιξει καθολου οποτε δεν μποÏω να σου πω πολλα. (Τιποτε δηλαδη) θα σου απαντησω για 4620 αμα θες παντως.

ΩÏαια λοιπον.. καλως ηÏθες στο φοÏουμ (που κι εγω δεν εχω γÏαψει πολλα :) Εαν χÏειαστείς οτιδηποτε απλα πες μου. Και απο υλικα (microchips κλπ) εχω μπολικα και απο λαθη που θα μποÏουσες να αποφυγεις :) Ο Mr. Braska αγοÏαστηκε απο ενα Hondos Center για να το μασαει η κοÏη μου που τοτε εβγαζε δοντια.. Εαν βÏεις ιδιον ΤΟΠΘΕΛΩ :)

Καλωστοοοοον! :) αντε να πουμε και καμια κουβεντα στην μαμα ελληνικη. :) Λεγε.. απο που εισαι, τι κανεις, πως το βÏηκες κλπ :) Εμενα με λενε ΑÏη, φταχνω τωÏα ενα sequencer αναλογικο και ενα SID :) (σιγα σιγα ομως :(

Works like a charm now!! So to answer my own question +-15volts will do fine on aout_lc! Thank you all guys! (and sorry for my stupidity :-[

AAAAAAAAAAAAAAAARRRRRRRRRGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHHH! I'm a pure cretin!!

Ummm.. it seems I've done something wrong and I've done it twice.. When I set it to 12/4 bits, the 4bits seems to work (almost) but all the others are just dead.. I have to follow the signal trail up to TL072 to see if the problem is on the opamp or at the 74hc595.. When I go to calibrate, it is just the same voltage throughout the range. :(

Thanks guys for the answers, I will put it under 15 v and tell you what happens (probably nothing) The thing is that my modular setup has a +-15 v PSU I've made and I wouldn't like to downgrade it since it will feed some yusynth modules as well So I'll check it and get back to you

Couldn't find something like it so I ask thee here. Could I use +-15Volt PSU instead of +-12V for AOUT_LC (for midibox CV, SID and seq) Thank you all! Aris

hi again, I was looking around if I could make it touch sensitive. Capacitive sensing is for now out of the question because it needs lotsa extra stuff (but I recently learned that microchip mCUs have all the needed circuitry on board). This is to be tested later. For now, I wait for the local component store to bring me carbon spray (the thing you see on remote control contacts) to check if I could substitute the switches (DIN module) with an analog, resistance measuring AIN module. If anyone has any idea, you are welcome to shoot away! I'm making a drawing of the keypad so I can upload it. I put a link on the wiki so I can fill it up tonight! :) (sorry for being late on this but I recently got a QY700 and been playing with it since Saturday non-stop :)

:-[ I read "If you are developing a new application and it's likely you will release your project, feel free to post " Rushed a bit :) Good to be here !

Hi all, I just built a harmonic table keyboard (it is a very easy project but I haven't seen anything like it except C-Thru's Expensive stuff) It is a midi Core module with two (for the time being at least) DIN modules to read the keys and some simple C code to do the mapping. I will post full details and the code as soon as it is a little more solid. The concept behind the harmonic table is that every note above the one you press is a 5th apart, the one on the top right is a major third and the one at the top left a minor third This makes playing scales, easier and playing chords even easier. I included a transpose function readily available so you can change root note without lifting your fingers (actually you have to lift your fingers but you can land them in the same place) I have some more information on http://synth-diy.blogspot.com/ (my DIY blog). Please tell me what you think and what you would like to see so I may add it. Thank you all, Aris 100_9422.JPG 100_9422.JPG
