Ah! The smell of burning electronics.
It looks like this test is over now. The TabletKiosk MP3400 blew up on me.
This morning, everything was going well. The MP3400 was charging well from the Sunlinq…
…but later in the day, when I was charging the Q1 Ultra from the MP3400, it all went wrong. The MP3400 overheated in a big way…
I had left the Q1 Ultra connected to the MP3400 in the boot/trunk of the car while I went out to pick up some beer and when I came back the unit was incredibly hot. When I took it out of it’s case, it was clear that it had overheated as the plastic on the inside of the case had melted onto the battery. Part of the grille had melted too.
I left it to cool for 20 minutes and it looked like it was working again but it didn’t last long. Its completely dead now. No lights, nothing!
Lesson learned. Don’t try and use the MP3400 in 32 degrees heat inside the protective case, inside the boot of a car.
Fortunately the Q1 Ultra is still working although i’m down to 60 minutes battery now. There’s no way to charge it up until I get home on Saturday evening. Here ends another Solar-UMPC test. Now where’s that beer I bought….

Spot the difference. (Technology moves on)
One year ago (see this post for details of the 2007 Solar UMPC tour kit,) I was using the setup below for my mobile blogging and tracking.
This year, its a lot simpler. And a lot more powerful. Notice how the phone, GPS tracker and Camera have merged into one device. Yes, the N82 is a real boon. The N82 camera is not as good as the S2 (as expected) but the ability to auto-tag while tracking and then post the images directly to a server over the Internet is a massive advantage.
You’ll also notice a change in UMPC. I’m now using the Samsung Q1 Ultra (with XP and HSDPA) which has an SD slot (negating the need for any cables for the camera) and a much brighter, higher resolution screen. I’ve also moved to SSD rather than the traditional, spinning hard drive. Its safer. The keyboard (A Samsung Q1 keyboard) remains the same as there’s still nothing out there that can beat it. You’ll also see the USB LED lamp. Still, a key part of the kit!
Now lets look at the solar setup. This is the setup I used a year ago.
And this is the setup i’m going to use over the next four days while I go work/camping.
[The Wife and Kid are off camping together and I was due to stay home and work but I've decided to come along and make a working holiday of it. Dads - this is the beauty of Ultra Mobile PC's!!!]
I’ve removed the lead acid battery from the kit and am now direct charging the Tablet Kiosk MP3400. It only charges during peak hours (one full charge per 100% sunny day here in mid-summer Germany) where the SLA battery charges during less sunny periods but the amount of energy you get in those few extra hours is minimal. I’ve chosen to drop the SLA battery and use the MP3400 direct on the Sunlinq 25W solar panel.
Here’s a post with more detail about using the two together. And a how-to video.
I’ll probably post a few solar computing thoughts while I’m away so stay tuned here for more. Weather is looking good!
