PCB per Braccio meccanico

-

sto per realizzare il mio primo circuito stampato. credo che per cominciare utilizzerò un pennarello indelebile per il trasferimento e una soluzione 2:1 di acqua ossigenata (12 vol) e acido cloridrico (33%) per il semplice motivo che li ho già in casa.

però prima vorrei sapere se il circuito che sto per stampare è corretto (l'ho allegato questo post).
si tratta di comandare 4 servomotori con un atmega328p-pu @ 16mhz, controllabili con 3 potenziometri e un pulsante.
l'alimentazione è fornita da un portapile da 4 aaa per un totale di 6v, che diventano 5v utilizzando il regolatore di tensione l7805cv.

che dite procedo tranquillo? ci sono errori? può essere "semplificato"?

c'è un errore di progetto ...
.
.. il 7805c ha comunque un "dropout voltage" di 2v e quindi ... richiede in ingresso minimo 7v ...
... basta che leggi il datasheet !

quindi ... le 4 pile non vanno bene ...  :smiley-roll:

dear all, working on image processing using raspberry pi, have installed intex usb web camera on raspberry pi. have used basic python script of image processing https://www.cl.cam.ac.uk/projects/raspb ... first.html required libraries installed on raspberry pi. script code: import imgproc imgproc import * # open webcam take pictures camera = camera(160, 120) # open viewer window display images viewer = viewer(160, 120, "the first step") # take picture camera img = camera.grabimage() # display image in viewer viewer.displayimage(img) # iterate on each pixel in image x in range(0, img.width): for y in range(0, img.height): # value @ xth column , yth row, place intensities variables red, green, blue = img[x, y] # test find colour dominant if red > green , red > blue: # red dominant, set pixel red img[x, y] = 255, 0, 0 elif green > red , green > blue: img[x, y] = 0, 255, 0 else: # if red or gr...

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
