brain machine kit from make magazine

Post by esquire20 »

Hey can anyone help with this?

I've been creating the brain machine from the make magazine with limited success.
I got the minipov3 working but when I tried to put in the software I got this message

Which I don't understand at all because I took the files "slm.c" and "makefile" and changed every entry of com1 to com9 (which is the corresponding value) before I made them into hex files.

Any ideas what the problem might be?
Bearing in mind I've only been learning these terms since this morning :p

So this is my slm folder
The makefile I am editing is in SLMfirmware

And this is the makefile edited with com9 instead of com1
Makefile.txt
(5.09 KiB) Downloaded 345 times
So any ideas why it thinks I'm asking for com1??

rename Makefile.txt to Makefile. make is using the uneditted file Makefile.

I managed to get pics of the minipov
Couldn't get the whole thing in so I've got the corner where the LEDs go as thats where the most damage is

Thanks
I changed the name and got the same result, so I deleted the original and got:

I've tried a few times and it's the same result.
Sorry if it's something really obvious but this is my first time making one of these.

the big blobs of solder are probably cold joints. you melted the solder without heating up the pin and the pad. it's important when soldering to heat the pin and pad and let them melt the solder. i would get some desoldering wick and clean it up. place the wick on the joint. press the iron to the other side and remove the iron and the wick when you see the solder flowing through to the top of the wick.

looks like maybe you should touch up the middle pin on the db9 connector on the top of the board. come in from the side with your iron to heat both the pad and the cup on the connector. this can take a while because there's a lot, (relatively), of metal there. touch the solder to the heated pad and cup, not to the iron.

touch up the diode resistor pairs. they are what's important for programming. looks like you could use more solder on a couple of them. again, heat the metal. let the metal melt the solder.

sorry, man. i don't know how to do much of anything from the windows command line, but here's the deal. make wants a file called MAKEFILE, Makefile or makefile. no extensions. no Makefile.txt. try typing "dir" to see what you've got. if you've still got your edited version try "rename Makefile.txt Makefile"

anyway keep trying. the brain machine's a blast.

Okay the rename worked fine and I finally got the program to run.
I got this message at the end

Hmm, I've resoldered most of it.
Some of the connections still aren't up to scratch.
That desoldering wire is so annoying, I think it's because the tip of the iron isn't as hot as it should be.
I'll upload a pic soon but just so I don't blow my brains out in the process, is there any other fault that could be causing this error??

Victory is mine!
I have the software working and my headphone jack has conviently melted itself into the correct place =]
I just have to get the last LEDs in and I'm off to brainwave land.
Thanks for all your help!
