The VE module has 11 general purpose I/O. Connecting these outputs to the DINx4 module should work as a vocal input (the program written in the flash memory of the VE module should be able to send 5V 0V output). Then with midi learn the PIC should recognize the command , not sent with a button or encoder, but with vocal command. I'm a newbie in electronics, so it may be something impossible, if someone could help me in this effort, thanks P.S. have a look there http://www.sensoryinc.com/ for more informations

Surfing the internet I found a sensory Voice recognizer module http://www.elettroshop.it/dettagli.asp?pid=375 Is it possible to "tell" the pic in the core to go an octave up by simply saying in the mic in "UP"? I think voice recognizing technology could be of great help to musicians on the stage.. Think of a midibox controlled by voice :D Well I had this idea, I looked to the datasheet of the VE module (32 pins) but i'm totally unprepared to work on it, what do you think?

After reading in Wiki SmashTV's how to connect LCD article, I realized that my lcd backlight doesn't work because it requires a negative voltage on the anode. Do you think that realizing the little converter using an ICL - 7660 like shown here http://shellyinc.com/ean-6.htm will do the trick? I'll connect pin 8 of the IC with the LCD anode what do you think?

Is it possible to use PLED technology with midibox? A display such as this http://www.elettroshop.it/dettagli.asp?pid=680 is useable?

Look at the datasheet I provided above I supplied the two poles of the LCD directly without passing through the core to see if the problem was related to the LCD. It lighted. I suppose that the LCD isn't useable for midibox, being an extended temperature range LCD it requires a negative voltage (4.2 anode or 5V max and 0V cathode) which the core output of J15 cannot supply (maybe). I'll try searching a new LCD

I tried to rotate, but nothing happened. I thought the problem was the trimm, so I checked resistance between the pin of J15 which connects to the positive pole of the LCD backlight and the trimm. 0 in the two pins of the trimm, and the value selected rotating the trimm on the 3rd pin. Measuring between the pin of J15 which is to connect to the - pole of the lcd backlight, I found 10k on the 2 pins of the trimm and 13,5 k on the 3rd pin! Is it possible that the problem is the trimm? Maybe I harmed it during soldering

Or I need to plug the PIC on to activate the backlight too? All of the connections and the voltages are OK, except for + and - of the backlight. In the datasheet recommended voltage is 4.2V in anode and 0V in cathode , but due to the voltage regulator in the core the voltage supplied is 5V.

I connected my ATM1602b (see http://www.hebeiltd.com.cn/lcm.datasheet/ATM1602B.doc) and I tried to connect power to the core to see if it worked. I didn't put the pic on the core yet, is it necessary to test the LCD? I thought at least the backlight would turn on by simply supplying the anode and the cathode of the LCD

I'll give it a try,what scares me is that my display looks a little bit different from the one in the minidatasheet

I found a working ATM1602B in my scrap SEE: http://www.hebeiltd.com.cn/?p=LCM.alphanumeric.blue but I don't know if I can use it. It has an extended temperature range and thereby requires a negative voltage, I've built a core module and 2 dinx4, and I would like to connect this LCD to the core. What do you think?

yeah sorry :D buttons FOR coin operated machines (Arcade games)

Hi everyone, I managed to build a Core and 2 DINx4 module. My objective is to build a simple midi controller but with a pedal interface. Here comes the problem: I wanted to use Coin Operated buttons with microswitch as keys, but their diametre is too far bigger than I expected and my pedal keyboard has to host at least 40 keys. well the panel comes a little too big! I was thinking to go for extreme modding on a Casio but mechanically this looks like a mad experiment. Have you got some Idea? Thanks

Does Mios integrate SID wavetable sequencer? If positive, does it work like the one in Sidstation os? thanks

Have you got a link to a catalogue showing this anti-vandalism stuff?

Hey smashTV, it seems it is your job to answer me! thanks really you're leading my project :D

You're telling me that success in electronics derives from being paranoic ;) Then I'll bring my core module to the city mental hospital :D Thanks for the advices

I'll try to be clearer: Is it correct to solder the 10k resistor directly in the same holes where the IC socket is soldered (pins RB5 and VSS)?

I think they're ok, I didn't check the voltage measures and the module works well. The capacity value expressed in mF is obviously important

Hi. I'm building a master pedal keyboard with 32 keys. I built a Core and an DINmodule, but I don't know which are the best buttons to use. I was thinking that I need momentarily normally open buttons, very soft to permit pressure by plastic keys. What do you suggest?

is it possible to harm diodes simply testing with a battery meter the resistance on its sides? I mean, I tested a diode and I put the + of tester on the - of the diode. Must I drop the last in the bin?

thank you, but I don't understand how to connect the two pins with a resistor: I made the pcb so that the 10k resistor connects RB3 and VSS; to connect RB5 and VSS I have to solder the 10k out of the pcb and not in the holes right?

one more thing: I built the JDM module using the .brd in Eagle: so the 10k pull down resistor is in RB3 of pic16f. how to put the resistor in RB5 (i'd like to program a pic18f)? Do I need to desolder the 10k resistor from VSS and rb3? Thanks a lot

Does the jdm work connected to the serial port of the computer without the connectors for core J3 and the 2 isolated bridges needed to make them work? thanks for the help

yeah brilliant what a stupid.. this is paranoia caused by my first core being destroyed by a short circuit :'( thanks for the help and good living.

Hello everyone. I built my DINx4 module but after soldering everything I'm in terror of burning the circuit by applying voltage. I get strange readings when I check resistance values of the IC sockets. I don't know if that's normal, but when I test the 4 middle pins of the sockets there's a resistance of 20Kohm between them.. I suppose every pin should be completely isolated from the other. I triple checked the solderings and there's no tin between the tracks. Thanks
