Hackaday Supercon 2017 Badge.

[@TheAmmoniacal]

I hope Hackaday paid you for this.

[@pcuser80]

The neck interface is cool and handy!

[@MobiusHorizons]

Amazing work as always!! I loved the detailed explanation. I've been looking forward to this video ever since I saw the photos on twitter.

[@mikehibbett3301]

Awesome design decisions. A lot of imaginative decisions there, thanks.

[@maxtorque2277]

That's all well and good Mike, but what did you do AFTER lunch?? ;-)

[@Tadesan]

Really amazing!

[@proluxelectronics7419]

Would make a nice PIC Dev board....

[@jcthe2nd]

Mike your a wealth of knowledge you need to post more videos please

[@ambient5]

Great work, as always...

[@Factory400]

Mike - that is so crazy nice. How many people on the dev team? How long did it take? What was the build cost?

[@mikeselectricstuff]

Hackaday Mike did the game & puzzle code, I did everything else. Only imported code was Microchip's SD card filesystem stuff.

[@TheDefpom]

Awesome project, I’m always very impressed by what you can do.

[@sebmadgwick2789]

I found that the formatted allocation size has a significant effect on SD card write speeds. The default allocation size varies between card capacities/manufacturers. Choosing the highest available allocation size for given card seems to consistently provide best performance.

[@mikeselectricstuff]

I did play with that briefly but couldn't see much difference.

[@JGunlimited]

I was blown away by the hardware, but my mind hurts trying to fathom how on earth you also wrote all that code!

[@bvs1q]

this is so beautiful, thanks for sharing all the things! (and designing/ making this in the first place)

[@tinfever]

I'm very curious how long all that took to develop. I feel like that would take me at least a year... Maybe two.

[@Nermash]

Mike, I remember you saying that you are not that keen on developing huge chunks of code packed with ui and everything. Did you do all this by yourself?

[@mikeselectricstuff]

Yes, apart from the games & puzzles, which were by Hackaday Mike. Probably the biggest code I've done for a long time.

[@roopi67]

Amazing engineering in short amount of time! Just curious is there a specific reason why you went for this microcontroller instead of an ARM based alternative ? I'm trying to get to grips with all the types of mcu's an their pros and cons. And to be honest this the first time I heard of the mips32 m4k, thought arm dominated this slice of the market

[@TheBookaroo]

Hi, just a quick tip, for replacing the display, instead of removing the battery holder, you could run dental floss and cut the foam pad that way I think?

[@andljoy]

That happens with larger HDDs too with 4k sectors

[@ovalwingnut]

FaNtAsTiC accomplishment! Plus 38 mins of pure engineering sex talk :) Thank you for sharing in such GR8T detail.. I want one for Xmas. Cheers!

[@Wimpzilla]

Awesome, i would have liked to get one, but the price tho! Also i watched your presentation, awesome job as always Mike! Watching you explaining your work and how you implement, invent, engineer is always a pleasure, you are truly a master combining electronic with arts and imagination. The final project is really a piece of art!

[@gotj]

Mike, are you a relative of John Harrison, the carpenter of the marine chronometer? I bet you are because, you know, Mendel's pea plant experiments and all that.

[@mikeselectricstuff]

No idea - Family is from Up North like him, but it's a common name up there.

[@stonent]

I was always hoping a relative of George Harrison.

[@gotj]

By the looks, he may well be.

[@johnhealy2092]

Mendels law and he was a monk

[@macro820]

This thing is crazy powerful!

[@keesnuyt8365]

Brilliant!

[@BenEishen]

no kill like overkill :) Thanks for sharing!

[@rchaffer]

"Neck Interface". Nice.

[@pdrg]

Inspirational and fun - thank you for sharing this

[@TheRealNici]

Your video files from this badge actually helped find a bug in the mpv video player, which was promptly fixed. :) github.com/mpv-player/mpv/issues/5097

[@landryderrick6851]

i guess Im asking the wrong place but does any of you know of a way to log back into an instagram account? I stupidly lost my password. I would love any tips you can give me

[@drakeamir5885]

@Landry Derrick instablaster :)

[@landryderrick6851]

@Drake Amir thanks for your reply. I found the site through google and Im trying it out atm. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.

[@landryderrick6851]

@Drake Amir it worked and I now got access to my account again. I am so happy! Thank you so much, you saved my ass!

[@drakeamir5885]

@Landry Derrick You are welcome xD

[@andrewschannel3635]

I've missed your videos mike, It would be nice if you could do a tear down and analysis of a e-call/onstar box as fitter to newer cars

[@NSAwatchesME]

impressive, how many hours did that take?

[@jonasniesner]

Did you get the "cheap oled"(which is based on the ssd1332 I assume) to work. If yes, how did you do it? because I wasted many hours getting it to work but still failed.

[@howdo5136]

Excellent job!

[@tomy983]

A lot of details! Nice!

[@JGunlimited]

Whoa! Amazing stuff!

[@christophers6034]

Hi Mike, Why didn't you go with a flat LiIon battery?

[@mikeselectricstuff]

fire, explosions etc.

[@thevideoman12]

Best thing was the "neck interface"

[@argusroot]

Amazing !

[@piconano]

That was an incredible video. Thank you. Sub'd :)

[@slap_my_hand]

That is awesome!

[@Tarbard]

Very Cool

[@Space_Reptile]

i want one of these

[@petti78]

Try buying one. Link is in the description...

[@Fan119]

I hope someone has already put Doom on it.

[@reanimationxp]

The badge hack winner went a step further, linked two of them together and made functioning, accelerometer-powered VR. While talking to tons of people and giving out parts from his personal stash to badge hackers. Quite a guy.

[@MrHack4never]

"Neck interface"

[@BenjaminEsposti]

Gah, you're so awesome! What's your IQ? 160? XD 19:00 What you could also probably do is use a little SEPIC converter IC (they make them now, in little DFN style packages), and if you have an available clock source, simply use a totem pole to drive a capacitive doubler to provide enough voltage for the LED. Ahhh, I love designing clever circuits, and the PCB spring is clever too!!! :D 20:22 That's why I don't like using more than 10k or so as a pulldown/pullup, unless it is absolutely necessary. I suppose here it is used to reduce battery draw. lol "power but" XD Nice using the transistor to turn off the voltage sense divider to save power.

[@gotj]

That's cool, well done !

[@gotj]

love the particles hahaha

[@markhodgson2348]

EMP will end all this KISS

[@gotj]

first !

[@gotj]

lol

[@bloodyl_uk]

Mike... Your a wonderful waffler, absolutely awesome!.

[@ledmage]

Thank you for making it so easy to hack and add things to. The amount of detail that went into this design is amazing.

[@Sousanators]

Fantastic video. As an EE student, the contents of this video are invaluable.

[@brikotube]

Outstanding work Mike. How much time took you to code all that, yo design the PCB, circuit. etc.?

[@AlexeiPolkhanov]

What CAD software are you using?

[@stevefriedl3983]

It looks a lot like DipTrace; I'm not much of an electronic designer, but I found DipTrace to be exceptionally easy to learn and use. Having second thoughts now, probably not.

[@ktrontrontron]

Got to use a badge in person, It's a fantastic piece of work!

[@groovejet33]

Im dizzy as foooke after that! Natter... Waffle..Prod ...Prod...Poke.. Waffle...But what a amazing mind Mike has... absolutely unreal. You know your stuff Mike, to produce a board like that ...to use as a badge ..Wow!

[@pmpbar]

Wow mike...this is very impressive

[@PatrickDelBarba]

How does the PWM of the power control line subsequently allow the regulator to shut off? Sounds like an interesting hack.

[@FrozenHaxor]

The voltage averages down to a level that is enough to keep the converter switched on, when finally grounding the signal the falloff is much quicker and so the restart does not occur. Nice idea actually.

[@Blowcrafter]

did you use a custom card IO library for the video playback or is it the microchip one? I did something similar a while back and ended up coding a custom memcpy that did double buffered continuous block reads from the card, which allows 60FPS playback of 128x128 24bit video. With the default IO lib it barely managed 10

[@GlennPierce]

It would be great if you could create a video of general development processes used to create something like this. I can never work out how you would start to design a board around a pic32. Do you use a development board or just start creating pcb's? I only have experience of very simple circuits that can be prototyped on a breadboard but that doesn't scale to circuits like this.

[@mikeselectricstuff]

I breadboard /prototype/lash up anything I'm not sure of. There's a pic of the first breadboard on the hackaday.io page

[@Arnthorg]

34:10 you can probably also use a piece of string to cut the sticky tape

[@coondogtheman]

That's a neat little gadget. Can you show us the video quality of this device?

[@NivagSwerdna]

Very nice project. I can appreciate the amount of effort it must have took to get it to that stage. Maybe some connectivity for a mesh network arrangement? Awesome.

[@TheRealBobHickman]

It's a really great badge/board. I just wish I'd had more time to hack it during the con. I'm still playing with it, and I think I'll be hacking it for a while yet.

[@sdgelectronics]

4:10 milli Siemens??

[@1pcfred]

Just a bit over the Moon for a badge.

[@yaghiyahbrenner8902]

Hey Mike. Thank You. Really Thank you! Great Work.

[@rchaffer]

As with so many of Mike's videos, 98% of this seems to like magic to me

[@pixlfactory]

You keep amazing us all the time, thanks Mike!!!!!!!

[@peterperkon5098]

I hope mike does more stuff without hackaday.

[@JGunlimited]

Looks like something you would see in a sci-fi movie!

[@Mr.Laidukas]

+mikeselectricstuff Mike, I would like to buy one for my self if memory card test is included in the firmware you get from Tindie. Do you get memory card test?

[@mikeselectricstuff]

It does include a simple write speed test. Note this test only indicates write speed in SPI mode via Microchip filesystem library - it will not correlate to speed in SD/SDHC mode when used with cameras etc.

[@truhlikfredy]

As always superb skills, hardware and video.

"quick video" but still, very cool :D

[@petti78]

Is this on Aliexpress yet for 5.99?

[@MrDubje]

Amazing!

[@rkan2]

It is pleasingly responsive :D

[@OC35]

Shipping to the UK starts at $40!

[@tsdarc]

some cards are slower than others 🎵

[@CPD-KD6-3.7]

That little thing is awesome!

[@stocklitv1371]

nvidia flex

[@dufflepod]

Just out of interest, could you tell us the BOM price, the board price & the delivered/populated price? Just curious.

[@mikeselectricstuff]

Hard to say as we got sponsored for some parts and the assembly. And I wasn't dealing with purchasing. The original budget was $30, I think it ended up around somewhere around that, excluding assembly, at qty 500

[@simoneguggiari8676]

Texilenene

[@douro20]

Does this PIC32 have an MMU?

[@mikeselectricstuff]

No, nor an FPU. DMA is the only fun toy.

[@izimsi]

EN pin on the converter is held by "power but" pin while measuring the battery voltage?

[@mikeselectricstuff]

only very briefly - a few uS - output cap holds supply while low.

[@gotj]

You wrote all that in C? Or in a HL language?

[@mikeselectricstuff]

Yes, C is a HL language ( relatively speaking!)

[@gotj]

How long did it take you to get all this up and running? Days? weeks? Months?

[@gotj]

A step above assembly indeed

[@Matlalcueitl]

Quite a large step above. And by the way, if C is low level language so is C++…

[@mikeissweet]

Holy hell! What a badge

[@NoName-bt3oy]

Mike ya legend! A new vid, this deserves a plate of bacon butties and a brew! I'll be back... Edit 6hr later... Great vid Mike, cheers. Now make some more!

[@kaunomedis7926]

Why PIC MCU? I know you love it, but maybe time to use cheaper and bigger chips?

[@mikeselectricstuff]

Why not ? It does the job.

[@gotj]

Even a scope ???? Hats off, Sir, you're the best.

[@mitropoulosilias]

why not on arduino DUE arm processor??

[@mikeselectricstuff]

Why?

[@Lion_McLionhead]

This is definitely better left to a phone, but good for demoing a PIC.

[@gotj]

How can I get one? I want one.

[@petti78]

Try the sales link in the description.

[@gotj]

That's the dithering we used in the original Macs

[@mikeselectricstuff]

Standard Floyd-Stienberg - I almost literally pasted the code from the Wikipedia page

[@gotj]

aka diffusion dither? It's cool, I still like it after so many years.
