In search of the ultimate Devo7E

Just added my cheap Banggood 3-position switches today.

One piece of advice, make your hole from the front to the back. Yes I know you have to kinda guess where to start, but if you try from the back, it has adhesive that can really make a mess of your hole. Don't ask me how I know.

I just used a 1/4 inch drill bit and went very slowly.... it's a pretty thin piece of aluminum.

Anyway, my main complaint with the cheap chinese switch is that they are not that long.

If you remove the existing switch, you can also push the metal cover from the back. If you push with the "tail" of the drill bit the adhesive slowly gives way.

then you can print a new cover (or leave it without, the black plastic looks nice anyway)

Good news PB
Watching this thread like a hawk...
(not that I have the skills to go this far...yet)

Yes Sir,
the 7e now established an unique and unchangeable character, simply amazing...
Is there enough room to swap the inner switches with the pots?

Something like this should fit....but I don't have the exact dimensions at the moment.

Edit: ..sorry only german, but...

Achs-Ø 6.35 mm (axel)
Gewinde-Länge 9.5 mm (thread length)
Länge 12.7 mm (length)
Breite 12.7 mm (width)
Höhe 11.4 mm (height)
(10 kΩ , linear)

Could pins PA0 / PA4 be straighten out before you solder down mcu? Don't bend them back, likely to break.
Ok not help you now but if pull apart old brushed motor you will have some fine gauge mag wire.
Other way would be to long winded Copper foil, etching. I once put ISP pads on QFN Atmega 8 and worked

Tip
Gently flatten end of the mag wire, scape it once to see bright copper. Then max out soldering iron and pre tin end. If your lucky should hold enough solder too solder too mcu leg.
Good luck!

Affordable no?

Oh and flux

I don't disagree with you

That said there was I time I used a gas soldering iron. One of the better ones with ceramic heat exchangers. Biggest issue I had wasn't very high temp but the rapid temp change. Once I slowly raised temp. To help used grease type flux. Heat till flux goes glossy but not liquid wait while then slowly rise temp till liquid and then check to see if part moves. Got good at it that didn't need flux.

something to think on with...
If you happy to lose mcu all ready fitted? You could just use soldering iron to lift legs a few at a time. Could even just cut legs with blade but would risk cutting traces. Then use soldering iron fit new mcu.

BUT YOU NEED PERFECT ALIGNMENT OF MCU BEFORE SOLDERING ALL PINS!! you'll need blower to move it

Is this the one? ebay US$2.10 shipped

Daryoon seems to have become the 7E god, hadn't looked into the 7E in a while and stumbled across his thread yesterday; well over 230 pages worth!

god? LOL...god no. Just sharing all the good works from the Deviation developers to the rest of the world. Free up the people who actually doing the development from producing cool stuff like the Universal module.

Watching this thread with great interest. The Devo 7e continue to be the best entry level radio. And really the only radio with it's capability in that size.

Just to throw a feline amongst the avians, how about a rotary encoder with built-in pushbutton? They go for like a buck-fiddy...

So what can the 7e do that the 6s can't? Other than be upgraded to be more like a 6s?

I'm not being literal, I'm trying to avoid disinformation. I see a lot of people who seem to think that the 7E has a unique form factor. That people don't know there's an option that avoids a lot of the issues with the 7E may be one of the reasons it's always been hard to find, or, as you say, unavailable now.

And yeah, having a 6S, I think I'd rather have the 7E display - especially if I could get it for 1/3rd the price of the 6S. That color display is unreadable in sunlight, and the touch screen is enough of a PITA that I notice where deviation falls short of providing full functionality via the buttons.
