    Teensy3 Kicad libs

    Best thing is to just import the gerbers someone posted from OSHPARK and use that as a reference. I never finished making a full on footprint for kicad.

    Teensy 3.xx and h/w (DIN) MIDI

    Not sure if it's any help but I made a PCB for this last year (it was my first PCB, and it should certainly be re routed or redone in kicad). It's a total copy of the schematic pjrc provides. This is the thread https://forum.pjrc.com/threads/27977-Midi-PCB https://github.com/jjrh/midi_shield

    Teensy3 Kicad libs

    Right, but what about the distance between the through hole pads and the smd ones?

    Teensy3 Kicad libs

    Started doing some work on building a kicad footprint and schematic symbol for the teensy 3x. Is there anywhere I can find good measurements for the teensy3? I couldn't seem to find any mechanical data on the pjrc website. I am mostly looking for pad sizes and their x/y position. I pulled out...

    15 Teensy's and counting.

    Super cool! Is there a blog post or write up of this? How do you deal with the multiple teensys showing up on different USB ports? (ie teensy1 showing up on /dev/ttyUSB1 one time and /dev/ttyUSB2 the next) Or is it irrelevant and you just see them as a bunch of USB hid devices?

    will this be a milestone change in embedded tinkering?

    My suspicion is this is to kill off competitors like the $9 computer, orange pi, etc. It could also be broadcom trying to empty their excessive stock. My less cynical thought is that the $25-$35 price tag might be a little much for parents getting something that could end up in the back of a...

    Modi - DIY MIDI Controllers

    Really cool board and the price is very reasonable which is a nice surprise. Also nice you share all the design files! --- One thing I always wondered with those tactile push buttons is how do people mount them? The only way I have figured out is: - have the button pressed up to the...

    Teensy3 Kicad libs

    Right, I know there are plenty of PCB's I can order but it's always good to have some more links. I'll try out some of the eagle libs and convert to kicad - or just use one of the oshpark pcbs as a starting place, it's probably not much work either way I was just hoping someone might have done...

    Teensy3 Kicad libs

    Does anyone have some footprints (either PCB and or schem) for the teensy 3.x's? I'm specifically after a PCB footprint that breaks out the bottom side pins in the clever way described in a couple threads. Thanks!

    Stand alone Audio Design Tool (please help, browswer testing)

    there is something called electron ( https://github.com/atom/electron ) which from what I understand is for writing desktop applications in javascript/html I don't have any experience with it myself, but it is part of the https://github.com/atom/atom editor. My assumption is for a existing...

    Analog modeling monophonic synthesizer on Teensy 3.1

    Just wanted to say I like it! I'm honestly a little surprised more people haven't started working on some serious synths (maybe they are keeping them secret?). The teensy+audioshield is just ripe for this kind of application, a really serious device is just waiting to happen!

    Is there a market for a Teensy 3.1 48 pin ARM stamp?

    No that's not the situation right now. The situation is that the option (that tindle breakout people keep posting) for getting those pins on the bottom layer is not elegant. It's not hard or particularly costly. There is a perfectly acceptable solution RIGHT NOW. Fab'n a new board would be...

    Is there a market for a Teensy 3.1 48 pin ARM stamp?

    You totally would(well maybe not after this discussion), I would love 100 gpio pins! Maybe to you. Maybe to most. I don't know but it seems to be a split, most of us not caring too much either way. There are a lot of interesting projects in the interface realm where 100+ GPIO pins would be...

    Is there a market for a Teensy 3.1 48 pin ARM stamp?

    Maybe i'm misinterpreting what people are requesting, but to me, right now the current Teensy 3.1 is fine. If doing this wouldn't take resources away from (in my opinion) far more important things and was trivial, I would say sure. It's been made clear by pjrc that's this is not feasible...

    Midi PCB

    Just thought I would say I successfully got the boards made from seeedstudio. I had one mistake, the diode silkscreen (maybe also in the schematic? - I should check...) is backwards. I discovered this after spending more time than I would like to admit debugging the board. At some point I'll...

    $9 computer on kicstarter

    It's a allwinner A13 (http://linux-sunxi.org/A13) some guys a bit back were working with the A10 ... http://rhombus-tech.net/allwinner_a10/ and their "Embedded Open Modular Architecture" (EOMA-68) which was a pretty neat idea, a SOC in a pcmcia form factor. One thing that is interesting is...

    Arduino.org

    I agree the Teensy site could be designed much better. That said I very much disagree that content should be put on forums. Forums are as a rule an awful medium for information. Lack of threading makes reading a discussion (with multiple quotes) difficult. It's painful to read 20+ pages of...

    It's sad how all this drama will (and probably has already, before it got public) hinder development,moral and innovation.

    Midi PCB

    Okay updated the schematic to be for the 3.3v. (I assumed those resisters are in series)

    Midi PCB

    are the two 47ohm resisters in parallel or series? Is the midi in 270 ohm resister the one on pin4 of the PC900?

    How to make a MIDI controller?

    I was hoping to find a seller on aliexpress. 6000 is only 420 which isn't all that crazy. If I can get a sample of them and they are acceptable I might be willing to eat that cost and try and get rid of the rest myself on ebay or my local hacker space.

    Midi PCB

    Going to be a teensy 3.1 (it's so I can do work with the audio shield) I guess I should add room for the two resistors on the midi out. Room for a dip switch might be cute.

    How to make a MIDI controller?

    yikes that's expensive and not quite what i'm after. With the traktor kontrol x1, they use those normal tiny tactile push buttons, with a SMD led and the silicone pad actuates it. They actually work rather well (you can't do live drums but you get the nice clicky feeling with the transparent...

    Midi PCB

    Okay I made the suggested changes (I think) annular rings should be bigger. I removed the 'extra pins' connectors which just added complexity. I sent the midi in shield to NC. I also fixed a issue where the pins to the teensy were connected that shouldn't have been. Let me know if I missed...

    How to make a MIDI controller?

    I'm not really interested in a midifighter style thing. (maybe some day but I have MPD 26 for that sorta stuff) so having a real tactile fast action style controller is not what i'm looking for. The buttons I want would be for stuff like a step drum machine, toggling ARP on/off, toggling FX, etc...

    I thought the shield was supposed to be connected to ground? Thanks, I'll look into it. Good call didn't think of that!

    How to make a MIDI controller?

    I would love to hear some advice on button hardware. What I really want is that silicone stuff that stuff like the Traktor Kontrol has. (no they aren't doing the contact thing, they have a nice clicky feeling due to the tacticle switches on the pcb...

    Midi PCB

    Hello, I'm making a stab at building my first PCB using GEDA. It's a copy of the schematic PJRC posted https://www.pjrc.com/teensy/td_libs_MIDI_sch.gif so I can start mucking around with the teensy audio board for synth stuff using my midi controller. I was hoping someone could verify I...
