    Re: Call for Talks

    Proposed talk:

    HackRF Design Review

    Learn about the electronics design choices that went into the HackRF
    Software Defined Radio (SDR) platform. I'll review the schematic and
    layout in detail, discuss the essential trade-offs of the design, and
    introduce some ideas for future SDR platforms.

    Re: Call for Talks

    I will be willing give a talk as a follow on to my main paper presentation and go in to more detail on the two devices that were built for it. Some op amp (transimpedance, voltage, as a comparator), photodiode, timer, schmitt trigger and decade counter stuff.

    If you would like to make a presentation in the HHV then please resond to this thread or PM me. Your talk can be about your latest project, basic electronics, soldering, just about anything. Last year we had some great topics and I want to keep that going.

    Great your talk went over very well and I'm glad you are presenting again.

    yes we have been kicking around the scheduling and I agree 100% needs to be blasted about. I think we will be able to do a much better job this year.

    Agree 100% on better scheduling/announcement of the talks. Don't be afraid to pull in people like Smitty and myself to help you get things organized/set up if you need it.

    It took me forfuckingever, but I finally found all of the pictures I was looking for. Ill get together a simple talk on why the front door is not always the best approach. It will only suck a little bit, I promise.

    I talked last year on plans I had for an Audiophile project. I've made some good progress on that project and would love to give an update, and possibly even bring prototypes (or finished kits) to demo.

    I remember c0re1287's I2C SPI talk it was very helpful and informative. I'd be very interested in a low level USB presentation.

    Sure, I could do something on USB, similar to what I did with I2C and SPI last year.

    What other talks are people thinking of doing?

    Sounds good to me. I figure if we can get 4-5 people that are at least semi-credible, we could have a decent panel.
    I've got an email thread started with some folks. Sorry, I should have posted here about it. Should we move the discussion here? I was worried that the folks I wanted to talk with weren't checking the forums yet.

I could definitely play the "well back in my day we had to erase chips with UV light!" old codger in that debate.

    And Smitty -- analog audio is the shizzle. Anyone who wants to understand where sound meets electrons has got to play with an analog synthesizer. It's a sound lab in a box. I've done a couple of talks on making sound with electronics, and it always goes over well. If you are interested in a collaborator or would like some of the material I use let me know. It's always fun to show the math and hardware techniques behind "that" sound in "that" song.

    I'm not sure I've got the cred to be on that panel, but I've done my share of uC work, mostly Atmel and Arduino but some Propellor and BASIC Stamp too. I'd love to be on that panel.

    At what point does a HHV talk qualify as a full DefCon talk? I think a uC panel could qualify. Would anyone else be interested in submitting a CFP with me?

    My current project (a headphone amp) is concentrating on the accurate reproduction of audio, not the generation or modification of it, but I've spent some time playing with CuBase, Reason, and ReBirth. THAT is a lot of fun. I need a better control surface than my mouse and keyboard to really get good, but I can see the potential there.

    I'd love to do a talk on electronics in audio: amps, synth, effects, mics, speakers, cross overs, instruments, etc. I'm interested in all of it.

    Last year I gave a talk on I2C and SPI. I'd be happy to repeat that talk, or give another talk on something else. Anyone have any suggestions for topics? I'd like to target some entry level embedded design. A few ideas I had:

    -Intro to USB
    -uC Debate - Which micro is right for me?
    -Basic circuits - LEDs, Buttons, FETs, etc.
    -Low speed Serial Communications (I2C, SPI, UART)

    Maybe we could also get some kind of Hardware/Embedded Design Panel together? Q&A type thing?

    Talk to Neil Kronenberg (you know, Mr. Niki7a? ;-) about getting into the program.

Is there a way we can schedule the talks soon enough to get into the program, kinda like SkyTalks do? That way, people will know about them and are more likely to show up.
