Hello. There has been some progress, nowhere near enough. I have had to take the hoop apart multiple times to address dead LEDs. I have been doing some work on the programming trying to get everything to work together. That is going slowly because there is a lot of learning going on during...

Thank you for the replies. I am still a novice at soldering. I have been practicing and have invested some in better equipment then I started with.

Hello, Yes, it has solder pads on both sides and I have tried what you suggest with the exception that I did not go super hot on the soldering iron. I went at the max of my iron (25-50w adjustable). I am not sure how hot that is but I think it is in the 500-600 range. I have a soldering gun...

Hey. I tried some very light stranded wire and then some light solid wire and then some heavier (20g) solid wire. All were bitchy to pull off. The 20g solid wire worked the best for a while. Thanks Russ

Hello again all. I was wondering if anyone has any tips on good techniques to use when soldering LED strips together. I am working with a strip of LPD 8806s that is about 3 meters long. I have had to, because of various reason, repair the strip several times. I have tried various different...

Okey doke. I was only saying that when you want to do something tiny the Teensy wins :) In my case I needed a choice that at 3/4 inch or smaller that could be embedded in the project.

Looks like the Freescale one is BIG. So, Teensy wins for anything that needs tiny. Freescale 52.5 by 80mm. Teensy-3 19mm by 35mm.

Thanks, yeah I have not run them down far enough yet to see what they will look like. I am hoping to get 3 or 4 hours between recharges. I think that should be plenty, I hope ;p

Hello again :) Hopefully, if everything works as expected the circuits cut off around 2.7v to stop from battery overdrain. Thanks.

Good morning. Thanks for the reply and do not even concern yourself with offending me. I have been trying to digest tons of information across the last couple of months and sometimes I get very lost. Ok, a lot to digest there. I looked around for specifics on how much current the teensy and...

I have been a member of many different internet forums covering a wide array of subject matter. This forum is most definitely the most openly helpful and informative board that I have ever been a member of. Paul and Robin, you do a great job. The Teensy is a great product and you and the...

That makes sense to this addled brain. So, in that case anything running off the 3.3 out from the processor is also getting decreased voltage. Thus if I have the sdmicro running off of the 3.3 out (and the fuel gauge and the blue tooth) they are also changing. I think I am going to try the...

Hey, thanks for the reply. I have that now, I did not at the beginning. Somewhere between Paul's explanation of the diode and my wandering off to the step-up I realized that was the way it works. Thanks for confirming it. I originally started my project with an Arduino micro and it auto...

Our club can be called the DFNs for "Dumb F&%$king Newbies" ;p

Ooops on the math error, thanks for that. Yes. It is 3600mah if you believe the battery label. The 2400mah comes from what I was seeing on the meter during testing. Ok, so that is the power draw, so I would be ok just hooking it into the circuit I assume. On the 200ma on the teensy VIN...

I went ahead and cut the trace today. Now I have to make sense of the libraries I found for this thing. baby steps.

Yeah, I noticed it too. Maybe we should start a newbie club ;p I haven't been a newbie at anything in a while. I had kind of forgotten how it feels so it is probably a good exercise for me.

Ok, all this talk has created another question in my mind and since I do not want to start another thread I will ask it here and maybe someone can help me. I had (early on) considered using a step-up in this to bring the voltage for the strips up to 5v. I found that they ran just fine on the...

You are welcome, however please keep in mind that 1. I suck at diagramming and 2. I know nothing about what I am doing. ;p But I am glad that they might help in some manner.

Hmm, that might screw me up then, having a diode in there anywhere. I am using 3.7v LiIon in parallel as my external supply. So I am right at 3.7 for the most part (with a range of 2.7 (lowest) - 4.2 (fully charged)).. Can't rewire the battery pack without a great deal of effort because it is...

Hey, ok, then it is not just me ;p I think I can just throw a diode between the battery and the VIN and I should be ok (at least if the rest of my plan works). I am planning on using a 3 position switch as my main switch. In position 1 it will have power coming in from the battery pack and...

Hello again. I am planning on running the Teensy from an external power supply but I also want to, when needed, be able to run from the usb in. When I first bought the teensy and told Paul what I wanted to do he said: So, today I put the teensy into the breadboard and ran some LEDs from it...

Thank you.

Thank you again. I do appreciate you putting up with my ignorance. Ok, I think I understand why the diode would not work. I had already looked at the schematic and was confused (and still am) by what I am looking at. But, neither here nor there. I'm putting up a pic of part of the back of...

Thanx for the reply. I was thinking of a diode from the teensy 3.3 v to the fuel gauge. Do I have the current flow wrong somewhere? The way I understood the issue they were discussing was that the power coming back to the microprocessor could fry it. So, my diode was simply to make sure...

Has anyone used the sparkfun LiPO fuel gauge with the Teensy 3.0? Hi again all ;p Before antything else, yes, I know that this is not the sparkfun forum. I decided to ask this here because you guys are nicer and because it is Teensy related. I had decided that I would try to integrate a fuel...

I am an expert at taking 50 cent ideas and turning them into million dollar implementations ;(

That's all I need is more ideas ;p j/k. Thanks for the idea. I have not started on the actual programming yet. I have sketched out a flow and done a touch of pseudo code but nothing real yet. edited in: So, I walk away with that idea in my head and now my brain is full of a "learning...

Hello again, I have been quiet for a few days. Doing research and ordering the final pieces I need. Today I got the tube threaded (again) and this time it appears that I managed to get it in with all LEDs intact. I don't know if I will ever be able to get it unthreaded again but that is a...

Thank you.

Thank you.

Ok, now I will go research what the AREF pin is ;p Thanks edited in: Ok, just found this tutorial http://www.pjrc.com/teensy/tutorial4.html. It's amazing how much easier it is to find stuff once you know what terms you are looking for ;p So, now I have something to play with. Thanks again...

Thanks for the info Una. That actually made sense to this newbs brain ;p So, I would knock down the voltage exponentially (say by a thousand) and could then read the voltage coming in from external and multiply it back up to get an approximate. That said, what is a safe voltage range to...

Thanks for the replies. Yeah, I have looked at separate fuel gauge boards and chips and such and knew they are out there. I was just looking for a simpler solution then adding another board to an already crowded mix here. I know that it would not be as accurate as a dedicated chip would be...

And still continuing. This is what the whole strip looks like right now. I have it laid out on the back of the table while I work on it. And yesterday I started the work with the Teensy. First I bread boarded it, soldered a few pins on and got the SD micro card talking. That's about it...

Continuing: Yesterday, rebuilding the power supply. It is piggy backed on the strip. It uses 6 Li-Ion 10440 3.7volts in parallel. The power components I added today. This is the last battery in the array. To the left is the power protection board (Tenergy 32003) to the right is the lIPo...

Ok, as requested, some pics. I will add more as I progress but for now I will post some catch ups. The initial supplies (back right around Christmas) My assistants (very important. They are my cheerleaders) Lois is on the left and Peter is on the right. My work area. I am set up in my...

I did some research and did not find a quick answer so I will ask. Is there a way to read the voltage coming in. I found a write up for Arduino and it sounded like you could just bring your voltage in across to an analog pin and read it. Can you do something similar on a Teensy 3? If so...

Thanks for writing this up. Came in very handy and got me right up and running.

Yes, I will probably do some pictures along the way. Yeah, I noticed that neep is trying to put a bunch of stuff in a smalll tube too. Great minds think alike, ya know ;p Thanx for the replies. 2/11/2012 - Today I am rebuilding my power supply. It was sloppy and so I am taking a couple of...

Not sure if this will help you or not. It is some code I found in a diy led hoop project at http://philihp.com/blog/2011/diy-led-hula-hoop/ All his code is at: https://github.com/philihp/Jubilee He has his logo bit mapped in a file called carrot.h: uint32_t carrot[158] = { 0x00000000...

Hello everybody, I am new to the forum and wanted to introduce myself and my project to y'all. First let me preface this with I know almost nothing about electronics, ICs, or microprocessors. I have basic electricity and electronics from the Navy some 30 years ago (taught me how to use an O...

Hello, newbie here but I have been looking for a similar solution, has to go inside a tube too. I found this http://www.ebay.com/itm/1-PCB-Li-ion-Lipo-Battery-3-7V-step-up-Convert-to-Output-Power-DC-5V-DLX-UPDC5V-/251115596858?pt=LH_DefaultDomain_0&hash=item3a77a7ec3a and am thinking of...
