Hi Guys
Im new here, hoping to get my first hobbyzone plane soon, its in the mail as we speak. Then I saw this and had to get it. So I have all the parts just need to make the circuit.

It seems the scheme is made in AutoTrax, does any1 have the file, so I can convert to PCB, or does any1 have any tips n mehtods to make the circuit easily, maybe some kind of breadboard diagram?

Many Thanks
Looking forward to any replies.

I may have the Gerber files on the engr PC. Can you use Gerbers?

BTW, it is a 2-sided PCB. Given that it is a simple project, it might be easier to just build it on perfboard.

dont think i can do a 2 sided PCB.
ill try on stripboard, the scheme just looks a bit complicated.

do you have any other diagrams or pictures that might help, maybe a high res pic of the backof the one you made?

thanks

Here is the back side. I think you are better off just building it from the schematic.

ok having looked over it again i think its quite do'able once i sit down and draw it out.

just a few questions:

1. the scheme shows 5 pins on one side and 3 on the other, but the chip has 4 on each. are the pin numbers on the scheme the same as the pins on the chip?

2. xport BAT+ goes into the LM2940T and the 5.0v output from that supplies the rest of the 5V circuit rite?

3. I dont quite get how to wire pin2 from the chip to the shutter header, does it goto pin 1 of ps2501?

thanks man

1. It is a standard 8-pin DIP. The schematic is a electrical diagram and is not a "physical" layout.

2. Yes. Just follow the schematic.

3. PIC Pin 2 goes to the PS2501. Please see schematic.

I highly recommend you find someone with electronic experience to give you some hands-on help.

ive made circuits before, just wanted to confirm a few things on this one.

im almost done now.

just wanted to point out the parts list is wrong.
states 1x220RES needed, actually need 2.

i ordered my parts all the way from digi-key in usa, which is tuff when im in UK. now i have to go find some locally.

Thanks for the report. I'll fix the BOM.

Then you are in luck. They have a minimum of 5 pcs for that item, so you should have four more in the bag. :)

yeh its ok, i ordered enough to make 5 full circuits so i can make the first n second fully. but just means i can only make 2 then i gotta get down 2 maplins (our version of radioshack) n go buy some.

thanks for the help m8
wouldve had it made by now but im a neat freak n tryin to fit it on the smallet board poss

also noticed the pin header digi-key code is wrong
i ordered them and got straight headers, which although can be used, are not as convenient as the right angled headers.

so part list should be changed
from:
A26508-ND

to:
A26510-09-ND (for 9 pins, enough for 1 circuit (3+2+2+2))
A26510-40-ND (for a row of 40) (more cost effective)

once im done all post some pics.

Thank you for the information. I will update the BOM.
