1  Using Arduino / Installation & Troubleshooting / Re: Uploading to Mega 2560 works in old software but not 1.0 on: April 17, 2013, 11:02:17 am
I found out that is not a problem of "size" is a problem of something inside the sketch. I tried to upload a previous version and it's uploading, then i "pumped" the size of the sketch and it's uploading fine.

At this point , what's the difference between Arduino Mega 1280 and Mega 2560? I think the sketch is calling a variable or some stuff like that,  that makes the upload stop.

any news?

In mine, is not illegal. I want to make just a small electromagnetic jammer. I dont think you would die due to 30volt smiley

still not working for me...

no one?

Hi i would like yo build an emp gun/ device , an electronic jammes , not necessary with arduino, i have found those schemes, could someone can help me in a step by step description? I'v made the coild but i dont know how to read schematics.  Thanks in advice

well i dont think is a matter of price, since the myAVR project i'v purchased was really cheap.  I dont know if the myAVR board, have a more sophisticated regulator, but i dont think is that sofisticated to make the cost grow.

BTW i really dont get the point of making arduinos not supporting higher voltages. 5v is too much for standard batteryes too low for li-po packs. 

I have a project with a myAVR board that i have purchased year ago, and this is working with different voltages, from 7v to 12v , you should just set the battery on the menu.
And there is no heating, no regulator theory etc.

If i supply 3.7v runs just fine, but i'm afraid it wont last long... i cant supply lcd's with different voltage since they have a max 5v ratings.

still not working

This is an  8 segment...

So how can i solve this issue? I would like to use 7.4v batteries
12  Using Arduino / General Electronics / Regulator gets hot with 7.4v and 11.1v li-po on: September 19, 2012, 06:31:44 am
I have an arduino mega 1280 and i have an 8 segment led attacched, and an LCD screen.

If i plug the USB power all works fine without heathing or something...

If i plug the 7.4 on the power plug, or the VIN the regulator just start to get hotter and hotter, till i cant even put my fingher on it. If i plugh the 11.1 it gets instant-burning!

How can i solve this? Why the usb ( i think is 12v ) is not having this same behaviour?

I'm in Belgium and the big wholesalers like RS and Farnell only sell to companies over here. So I buy most of my stuff from Chinese Ebay sellers and Tayda electronics in Thailand. Cheap but you need to have some patience.
hahahah farnel has this piece at

4€  Cmnot that's criminal smiley-grin!

I think i'll go with

futurlec.com

Really gr8 prices.

Just beware that all of these overseas shops take a good 10-14 days to get to you.  But they are cheaper.  Futurlec has been good to me but it's 2 weeks each time I order from them.

I'm quite experienced in overseas shopping. So no problem for me... with 1,5€ you buy 10 stripes that here costs 50 cent for every pieces, that's a LOL!
