Have a Question About the Sudden Impact Design Challenge? Ask it here!

Yeah Shabaz, large events usually bring in mobile stations to increase coverage for everyone.

I kinda of figure you would not want to run on wifi as the bandwidth would be used up.

I assume brain implants are not allowed.

I would think that such a system should have some high security / encryption or hackers from the other team could use the data to figure out who is weakest and target their plays around them.

Interesting challenge Christian.

Can the date for final application to this challenge please be clarified, I'm seeing one date as November 21, 2014 and another as March 27, 2015.

Thanks

Kas

Kas -

Applications from prospective competitors are due November 24, 2014; we hope to select the challengers within a week.

The design challenge itself will run from then on until March 27, 2015.

Thanks!

Best Regards, Christian

Hello Joshua, sorry may be i'm late to reply and u've already figured it out all the way. but still replying as i hope it may help u or others somehow.

I'm not an expert and have never worked with this chip [AD8232] but it seems to be a beauty to me.

AD8232 EVALZ has an analog output [TP15] which can be directly connected to a microcontroller's built in ADC. and obviously u can use an arduino. as the ECG has frequency components of 1Hz to 100Hz, simple 10bit low speed ADC is good enough to capture it. most interesting part is the board uses single supply and the output is already level shifted [not sure - i hope so], so the signal will stay in between 0 - 3v.

AD8232 has built in opamp to imply low pass filter. They have built in configuration. but if u want u can utilize it in ur way through TP16, TP17. u may need some collection of SMD resistors and capacitors, as i see the board has lots of unused pads to provide flexibility to the user.

the internal instrumentation amp has option to imply high pass filter to avoid motion and unnecessary signals due to displacements of electrodes. however, it has internal circuitry to detect if the electrodes are fully displaced [TP12, TP13]. but u have to buy electrodes or design wearable electrodes if u want to use it on the body surface of the athlete while performing [creepy].

TP14 [fast restore] can be used to control the 'amplifier rail on' to stabilize the output for quick recovery after an abnormal signal [like lead-off].

TP18 -> gives an option for DC LEADs off detection and TP21 can be used to shut the chip down.

the RLD [right leg drive] will definitely help in noisy environment.

however, may be I am not right with all the above stuffs. if anyone finds anything wrong please reply back to let me know.

I loved this chip - except one limitation -> it has inputs for only two electrodes, means u can get only one lead combination at a time [LEAD I, LEAD II, LEAD III]. in my experience, i have seen most people having good signals [high QRS complex] for LEAD I, but few people has low LEAD I and LEAD II, but high LEAD III. so if he does not get good signals from one combination then he has to switch the electrodes manually for different combination. Now in a game running on, u cannot do that, right? and the device may show that u are struggling or something is wrong with the device :-p

The ADuCM350 looks nice, but I've just noticed it only comes in a BGA package. I was considering making custom hardware, but the BGA is not easy to solder by hand.

These are all great points and I thank you for your input. I am editing my application accordingly

Do we have to use Raspberry Pi in the our design ??

I dont see anything in the description that limits the choice of micro controller or microprocessor

I would re-read the requirements to be sure but on a quick scan, I would say its fairly open, just a limited but quite generous budget and a nice set of sensors and a Scope to help you along
