Ben Heck's DIY Cell Phone Part 1

OMG please tell me that Nintendo shell on fire was an Adobe After effect :P #DontHurtNES

A little while ago, some of my sharper-eyed viewers saw that my phone number was briefly displayed on screen. Since then, I've received calls from a few of you. And while I love meeting my fans... my mom is starting to worry because she can't get through to me on the phone anymore. So please—for my mom's sake—do me a favor and share your comments on my show page instead of calling? Thanks so much, guys!

Amazing project, one of my favorites! Some small European companies actually still make phones like that, for that exact purpose. Call it minimalism, call it social networking exile, don't know, but it's pretty cool nonetheless!

11:30 The reason you get an "extra" 13 (carriage return) is because that's what you typed and sent to the modem.  AT followed by the enter key (which is 13 hex).
So you get echoed back the AT, enter (13), followed by a carriage return (13) linefeed (10).

Also if you are going to be ignoring all the echo's, you can just disable echo with AT E0
(enable with AT E1), the only real reason to have echo is to see what you typed if you're running a visual terminal console.

Awesome ring tone Ben. I like Golden Earring too!

I was hoping for Part 2 this week, seen this one and I am not stupid or childish enough to take Ben's number and do anything with it. Part 2 please, and please be quick uploading it!!!

Hayes modem commands FTW. Btw, AT = "Attention" i.e. "I want you to do this instruction". Back in the BBS days you used to literally command your modem to talk to a BBS using nothing but a serial console and manually typed AT commands. ATD = Attention, Dial... ATA = attention, answer... ATH = attention, hang up... Etc... Cell modules still use the same commands decades later because it's a good standard. This is why the "Ring" looks like it does as it was designed for an actual human looking at a serial console on their Apple II

Can't wait to see part two a second time ;)

[AmrMKamel]

I really enjoy watching your videos... Can you please tell me what is this program you are using as a terminal? Thanks :-)

[Videoneer]

Beat you to it months ago, Ben ;) I built mine using a SIM9000 GSM, a mechanical keyboard (cherry keys) and a few other goodies.  I wish I made a segment on it though...   :(
As always, AMAZING work Ben! Thank you for all that you do.

Late to the party, but I love this project.  I own a smartphone only to have a mobile portfolio/small camera.  It has no social media apps installed, and well, to be brutally honest, I have no friends, so texts are only from business numbers. The idea of a phone like is something that should come back, sure you can get a flip phone, but a basic BASIC phone is even better. The idea that modern phones detach people is frighteningly true, I see more people recording and taking photos instead of taking things in with what they were born with.

Thank you The Ben Heck Show for the information.  I will try it because I've just lost my fulltime job and now only working 18 hours a week.  Not enough to feed my 7 kids.  So I will try you information while I'm looking for a full time job. Thank you again and all the best to you.

Nice lecture, not the solid dry dust. Just the much it needs to get hooked :-)

[MakarovFox]

I remember more than a decade ago that I imagined that cell phones would end up being super small but in the end we went from the brick cell phone to the tile cell phone

[devinsharpe]

What programming language would he use for this project?

[originalmianos]

Use a finite state machine to parse the AT commands. It's much easier than parsing it line by line. Specially if you want to handle timeouts. Even if you do it character by character you might end up with a long switch statement but it will be simpler code.

Nice project! Have you ever considered making one on the Banana Pi? I recently acquired one, but had some issues with things such as wifi, and was curious to see what you would do if you got one.

[nullwii]

Good I am glad he got my message about his phone number

[Adamisawesome]

What programming language does he use ?

[MetalHermit]

Random question, Is the only way to control an arduino with a raspPi is using the raspPi usb port, or is there IO on the rasPi that can be used instead, I'd rather use my usb port for my battery then arduino.
