Ben Heck’s Raspberry Pi Bitscope Mod Episode -- Episode 223

I'm working on a small project to convert an old rotary phone into fake digital rotary phone. It will basically pretend to be a rotary phone, but inside it has a raspberry pi that will connect to a computer and it will communicate via tcp-ip. This will be used as a prop in an escape game of a friend

The problem is when I put everything inside, the pulse counter and hangup switch seem to interfere with each other and something else. Both signals just go crazy on the gpio. It can be interference through the mass (the metal inside the phone) or through the air or something. I don't have a scope to understand the kind of interference those signals are having and what kind of filters I should create (maybe a capacitor or something).

I think a bitscope might do the trick (since a normal scope are so expensive for such a simple project).

Great episode btw!

I was excited to see this episode. I've never owned an oscilloscope I've always used whatever was available at school or any workspace I've attended. This would be great for a first one. Could it be made even simpler using a Raspberry Pi Zero? Love your channel and look forward to more projects

Cool build. The uses for something like that are endless. I run the score board for my old high school's football team. The control panel constantly acts up. With something like that you could reverse engineer the signal and then use it for the control panel.

Hey Ben

I love the simple projects you put together. I love working with electronics and continue to do so as a hobby, My passion is collecting old broken gaming consoles and bringing them back to life. I mostly use a Harbor frieght brand multi-meter just to test with. If i were to save up i would love to create the project that you made on the show since that would make it so much easier with working with these old consoles. Thanks for the awesome shows that you and your crew come up with

That is definitely the sleekest design I've seen yet, and a great use of the new pi screen with the bit scope. I've been drooling over that thing for some time now, but alas, my budget will not allow me to acquire it. I've had to settle for a cheap oscilloscope assembly kit from China and it's been a pain to use. Starting to wonder if I got a reject kit. Get what you pay for I guess. I do rather like that interface on that bit scope software though. Definitely would come in handy for my projects like my environmental control ethernet lcd shield that I'm working on. :-/ I'll figure something out one day. Enough about me, great build.

That's fricken cool.  I think I've watched Dave Jones tear down a thousand oscilloscopes, but I've never actually used one.  I'm getting into oscilloscopes in my instruments class in the next two weeks, and something like this would be great to learn with.  I could also add octoprint to it so it can be an interface for my i3 when not being used to probe the depths of cool electronic doodads.  I'm pretty sure this is my favorite of all the projects that you've done.

Great show, i will have to try this this is much more compact that the one i used in the Navy and the software has everything i would need to use it for.

Great episode.

Now I have some ideas about how to set up my bit scope as a stand alone oscilloscope.

Nice project Ben, i would attach a ribboncable to the pi to bring out the GPIO-pins to a breadboard in front of it. That would be THE setup for my 11yo son to tinker with.

Great show Ben,

I do like how simple that scope is. I am lucky enough to work from home on software development 4 out of 5 day a week.

If i have a problem i only have a multi meter and no scope. Your project seems like a great solution to this even without a 3d printed case.

As space is not as critical as your build, i could mount the boards normally, use the usb cable for the bitscope and make a wooden enclosure.

This is your cleanest build yet from a point of few soldered connections.
