Demo of building a portable Pulse Oximeter Device with Gadgeteer

This is the source code for a demo I did on YouTube for building a Portable Pulse Oximeter Device with Gadgeteer.

Great! Thank you!

Before everyone gets too excited, tell me what you think of the video quality.

4

15 seconds of black screen at the beginning. I watched few minutes and it seems a little bit blurry to me. Actually it was jumping between focused and blurry.

5

Excellent, one issue is that the code is not really visible even when full screen, it might help to reduce the resolution when capturing the code editing. It might just be me, but I like to see the code writing process esp. if I am not familiar with the topic/technology.

6

I tried it again with some changes so I’ll see if its any better and if so I’ll update it

7

OK give that a go as it should be better.

8

Much better! I love your videos, especially when it shows the collection of your modules. :smiley:

9

I didn’t see the first version so can’t comment on the differences. This is a good and succinct demo that shows the simplicity of the Gadgeteer platform!

10

Well presented

And I almost choked reading your profile on TinyCLR :slight_smile:

11

Seemed like you were going to show about 10 more seconds of content at the end - the bit where you said "see, this is now running without debugging and not attached to a PC :slight_smile: "

12

OMG! I won’t be able to sleep tonight. “Go away Vilmer!!!” :smiley:

Great job on the video.

13

I just finished watching the new video, it looks great!

14

Excellent video, nicely shows how easy it is from start to finish.

Hi! Thanks for the video, it’s very good.

I have one question: the program didn’t work with my gadgeteer, it stays in “probe attached” all the time. Could it be a sensor problem?

Thank you!

16

Which sensor are you using? I tried some different probes combined with the Seeed pulse module as I was looking for an ear clip pulse sensor for some human performance experiments I wanted to run, but it seemed that the LED inside the sensor wasn’t strong enough to penetrate my steely ear lobes (I suspect the Chinese sold me a vet ear clip), but I’ve had no such problem with the probe that come with the Seeed sensor.

The correct way to apply the finger sensor is LED on top shining through the base of the fingernail and sometimes I’ve had to give the sensor a bit of a wiggle to get it to seat correctly.

Hi Duke, thanks for the answer.

I’m using “Pulse Oximeter 1.0 for .NET Gadgeteer by Seeed Studio”.

I’ve tried to give the sensor a bit of a wiggle, but it didn’t work. The program stills stays in the condition of probe attached, making measures all the time.

My Spider is plugged into a “USB Client DP”. Jus in case, have you ever tried to provide power with this “USB Client DP”? If yes, does it work?

Thanks a lot.

I’ve built a number of variation of this project and I’m pretty sure I’ve covered off a number of different power supplies without any problem. So lets work through what you have here and see if we can get it working. Which mainboard are you using? Can you post a Designer view and I’ll recreate what you have put together here and see if it works for me.

19

Hi Duke!

I’m using FEZ Spider 1.0. The Designer view is attached, the only thing that differs from your project is the Display T35.

Thank you for the help.

I can build one of those, what are you showing on the T35, I assume just the pulse rate and O2 saturation for now (maybe signal strength as well)?
