Biomedical engineering application: Digital hearing aid

-

our project title " digital hearing aid" .
simply, receives audio signal make processing on (e.g. filter ) , output amplified version of input signal. recently, lot of features can added above simple design. need assistance?

we need assistance?

do you?

quote
simply, receives audio signal

what does? where?

you realize arduino not particularly suited audio processing (that pesky negative voltage, 1 thing). not mention is, in general, far slow.

quote
then make processing on it

random processing? arduino not digital signal processor.

quote
and output amplified version of input signal.

output what?

quote
a lot of features can added above simple design.

what design? see handwaving.

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

How to format a Get Request

i have external server running mysql. have installed php script that, when accessed http deliver data 1 of tables. works fine browser: code: [select] http://www.seti.net/php/getevents.php i cannot figure out how send command arduino. have ethernetclient library working , can access google in example. when send command through client: code: [select] client.println("//get /php/getevents.php http/1.0"); the server returns: code: [select] </head><body> <h1>method not implemented</h1> <p>get /php/getevents.php not supported.<br /> what correct way format in arduino? i use send temperature web server. note lack of http version , additional blank line after - not sure whether difference important works: code: [select] void  sendtemptoserver() { char getrequest[80]; if (client.connect(server, 80))   {   sprintf(getrequest,"get /cgi-bin/arduino.cgi?reading=%s&arduino_id=23&sensor_id=1",t...

avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
