Fitbit Aria

2015/05/14 By staze

Fitbit Aria-WhiteBeing, obviously, a Fitbit fan, I picked up a Fitbit Aria a bit ago to track my (and the rest of my family’s) weight. I had been waiting patiently for them to update the Aria to support something a bit more modern than 802.11b, but sadly, that didn’t seem to be in the cards given their lack of response on the forums to requests for such functionality.

The scale itself feels and looks very nice. The top is glass, and the screen is easy to read at any distance. Unlike my previous scale, you don’t tap it to wake it up, but rather just stand on it and it takes your weight. Setup consists of powering the unit on with 4 AA batteries, and then running an application on your computer (I believe you can also use the phone app, but I haven’t tried) that finds the wifi network being broadcast from the scale, then telling the scale to join your home network, and to associate with your Fitbit account. Once that’s done, when you weigh yourself, it will say weight, figure out your body fat (assuming you’re not wearing socks or shoes), and then generally figure out which account the weight belongs to. If someone new steps on the scale, it assigns that weight to a “guest” which you’ll be able to see on your fitbit account as “guest” and be able to assign them to either another user ((at which point it generally hides the weight unless the user has decided to share their weight)) or yourself (or just delete the measurement). You can invite others to use the scale (up to 8 total users), though I have found you have to use their actual fitbit email account. If you use an alternate account, the fitbit invite accept never seems to work. So, I’ve since added my wife, and my son to the scale ((interestingly, even though I can’t put in my 21 month old son’s weight into the Fitbit app as what it actually is (claims it’s invalid), the scale can weigh him and that does get put into his profile accurately)).

Now, the bad part. It seems that Fitbit had a bad run of these scales in the 2014’s. Judging from some online research, it seems to be a problem caused by sloppy wire routing at the factory. Looking on their forums, it seems Fitbit has been really good (as usual) at replacing malfunctioning scales and since the early 2015’s, the issue seems to have been resolved for most people getting replacement units. Mine started exhibiting this issue relatively recently, and after talking back and forth with Fitbit’s Aria support, they agreed the unit was defective, and would get me a new one (even though I no longer had the receipt). I don’t have to send the defective unit back, so I hope to attempt to repair it after the new unit arives. My hope is that I can use a couple scrap cat5e cables, or maybe some phone cable to replace the wiring, and provide some extra protection for the wiring. An initial opening of the unit (which I did after getting notice they’d be replacing the unit) didn’t show anything horribly broken, but it still does occasionally wake up on it’s own, or error out during weighing. =/

That aside, and assuming the new unit works as expected, I would definitely recommend buying one to anyone that asked… although I’m still hoping they update the unit to support at least 802.11g, if not 802.11n. That said, the unit is only really on the network once it’s powered on, so the fact it’s 802.11b isn’t THAT big of a deal. =/

Fitbit Zip

2015/05/08 By staze

Fitbit-ZipI recently picked up a Fitbit Zip at a Radioshack store closing for a heck of a good deal with the idea of giving it to my 2 year old son to see just how many steps his short legs make in a day. Obviously he didn’t need a One, or a wrist band style Fitbit, so the Zip seemed perfect. It still clips to clothing, and the battery reportedly lasts about 6 months (a CR2025, I believe), and best of all, it syncs over BLE (Bluetooth Low Energy). In the first few days I had the unit, it counted well over 8,000-10,000 steps a day (often beating both my wife and myself). The only issue I found was that it didn’t Sync quite as reliably as the Fitbit One. It seems that in order to get the 6 month battery life, they have the unit go into standby after a bit of inactivity. So during the night, when we’d remove the Fitbit from his clothes, it wouldn’t sync. I had to actually place the unit much closer to the receiver to get it to sync during the night (I’d just leave it on my desk which is where the receiver is). Other than that issue (which will come back) the unit is great. It’s small, does a good job, and we loved it.

Then, sadly, the unit seems to have fallen off him when we were out shopping one day. And because the unit goes to sleep with inactivity, you can’t use something like Lightblue Bean (or any other BLE scanner) to find it. It just happily sleeps away, with no ability to say “oh, it’s in this store/parking lot/etc”. Sadness. I’ve since contacted Fitbit to see about a replacement, but at this point, I’m unsure. Hopefully a new one will show up, and we’ll get back to counting. =)

As a product though, it’s great. I’d suggest one in a minute for just about anyone. And if Fitbit could update their firmware to have the unit wake up once a minute or so, just to “ping” a BLE signal, so that you could see if it’s anywhere near you, that would be a great addition for finding the unit. Sadly, I think someone picked it up and didn’t turn it in to lost and found. =(

UPDATE (5/11/2015): I just received a replacement Fitbit from Fitbit in the mail. Awesome job guys, thanks so much!

Flir E4 (EX Series)

2015/04/25 By staze

Flir-e4I know I’m late to the Thermal Imaging Camera (TIC) party, but I just recently picked up a Flir e4 off eBay for a steal (about half price) from a seller that clearly didn’t realize what they had ((I say that because the unit had firmware 1.19.8, which is supremely hackable, and goes on eBay now for at least a $500 premium)). The unit arrived and although the battery was mostly dead, it fired right up, and worked great. I’m not going to go into too many review points since it’s been reviewed here by someone much more qualified than myself. Mike also is the source of the information that got people hacking these cameras from the e4 to the e8 model. Basically, a $1000 camera becomes a $4000 camera. This is because Flir, logically so, used the same hardware for the e4, e5, e6, and e8, they just limited the resolution through software. From a manufacturing standpoint, this makes great sense. And I’m sure they also QC the whole unit differently based on the model. That said, Flir has tried to fight this process via firmware updates to the unit, but as far as I know, each of those firmware changes has been circumvented (all of that is documented on the rather lengthy forum thread on the eevblog forums). Before the “upgrade” the thermal image was, I would say, useful. Especially with the MSX tech in the EX series. Basically, it overlays the “edges” of a visual 640×480 camera on top of the thermal image. The e4 defaults to 80×60 resolution in IR, which at a distance, is fine. Sure, a hot spot might look like a blob, but it’ll get you in the neighborhood. But after the upgrade, seeing 320×240 (16x the resolution), it’s amazing. The upgrade also buys you things like Picture-In-Picture, auto-hot/cold spot detection, etc.

My only complaint about the hardware has been spoken elsewhere: using MicroUSB seems like a bad choice by Flir. Just seems like it’ll break at some point. Also, interestingly, on the Mac (10.10.3), when you plug the unit in, it mounts the internal memory as a memory card. But trying to eject it, it just remounts 5 seconds later. =/ Interestingly, you can change the camera to UVC mode (which allows it to be used like a webcam over USB), but that seems to kill the ability to pull images off of it. Also interestingly, the Flir tools for the Mac (Version 2.1 off the Mac App Store) don’t see the camera at all (this could be due to the “upgrade”). The Windows version works fine.

Another odd thing was charging. I thought the unit wasn’t charging with a normal USB charger, but it turns out if the unit is “off” (or rather, in it’s “sleep” state), it doesn’t show the charging icon unless you press the select button on it.

I also bought the soft case for the unit, as the default Pelican style case is obnoxiously huge for the unit. I’d rather grab it, my Fluke DMM, and go… with the default hard case, that’s nearly impossible and still having a hand free. Further, the EX series is already rugged. No reason to throw it in a case that could probably take a 10M drop. Maybe if I was flying around the country with it and wanted to check it. Guessing the case choice was made by the same group that designs FLIR’s military style which needs the rugged cases. I have no idea.

Overall, I love (LOVE) the unit. And coworkers have been drooling over it a bit as well. I expect I’ll be doing insulation audits on their houses at some point. One professor is wanting to know how it works for seeing people in the dark (I’m sure he’s thinking something related to Sasquatch). =)
