I'm feeling so remote!     To expedite my development, I visited the Lizard Lounge (EFM32 Community by Energy Micro) and found an IR Remote Control project that works with a Nikon D90 Camera. http://forum.energymicro.com/topic/32-ir-remoteintervalometer-for-nikon-d90-camera/   This project is for a not specifically for the STK3700 so it required some work to get it fully working. For the STK3700 the IR LED need to be connected to pins 4 (PD9-anode) and 6 (PD10-cathode). Thes ...
State of the Heart I've been engaged by one of my clients to produce a beating heart for a robot. Here is a picture of the prototype front panel that I created.     The panel consists of two printed plastic parts, a red heart, a matching black panel and 24 red LEDs. The black panel is rebated so that the red heart mates into it. It fits like a glove!   The client has signed off on the design and now I am about to design the electronics for it. I will connect it up the Giant ...
Delivered As Promised! As a promise to Gerrit here is a silent video of the Energy Harvesting To Go Kit operating a LED using the onboard TEG (Peltier device). I've disconnected the EFMGG_STK3700 from the Energy Harvesting board and replaced it with a white LED. I've also selected the TEG power source using JP2. Aside from that no other modifications are required.   The silent video shows my hand heating up the TEG to produce power to periodically blink a white LED. The LED will blink ...
PrologI have measured the power consumption of this detector, that I got recently. Many of you have already checked the energyAware Profiler application from Simplicity Studio and know how to use it, but it is also possible to monitor the power consumption of any of your external applications with the STK, even if your external device does not run EFM32 chip. OK, so maybe not all external applications but the ones that can be power supplied from VMCU domain on STK. Also remember that the maximum ...
When looking around for energy harvesting solutions I found quite a bunch of intersting techniques to get motion into energy. A lot of these are highly experimental, but look promising for the future. I'll highlight the things I found most interesting:   Electro-active Polymers (EAP) Please, please, pleeeeaaassse, can I have these? They are a new way transform between mechanical and electrical energy, in both ways. EAPs can be used as 'muscles' / actuators and as generators   EAP as ...
Hi, Yesterday I got the carbon monoxide detector that I had ordered a while ago for roadtesting and I wanted to share the video from the teardown. I did this teardown in order to disable the piezoelectric buzzer, which is very loud, especially when you want to test it while you are in the short range. The device itself is a simple design. The one thing I am not sure what it is inside, is the metal can. The user manual says that the detector is only for carbon monoxide, but this metal piece can b ...
Trial & Error Tonight I've been trying to generate enough energy out of motion to light an LED; my target is to use 'harvestable' energy from a bicycle ride to generate enough energy to light the back and/or front light. As you could have read in my previous post, I first had the plan to use vibration as the energy source to light the LED. Unfortunately, no piezo was supplied, and the energy density of piezo actuators is too low to be useful on a bike.   Instead, I tried to explore the ...
The board arrived   So I received my board this week and it has been fun. Got the software installed and ran some of the examples and they worked great but then got to thinking about the project. I also showed it to the sustainable engineering lecturer at work and had to make sure he didn't leave my office with it.   Trial   I decided to place the system on my brew pot while I did a batch of beer to see if the energy harvester would continually run as I was worried the peltier ...
There are many ways to skin a cat. Some are simpler than others. After some familiarisation with Simplicity Studio I have found and even easier way to open, build and test the examples. Here's a silent video of the process.   All you need to do is;      Click the Examples tile in Simplicity Studio under the caption Software and Kits.      Select your Development Kit (in my case STK3700).      Select the example project you wis ...
How did you get up there?It wasn't easy. - Egg Shen from "Big Trouble in Little China" Here's a very short silent video that was recorded in real time showing IAR Workbench up and going with the Giant Gecko. It is best viewed in full screen mode so you can read the screen text.   I am using Windows 7 and all I did was follow the instruction pamphlet to a point and had to improvise when a reference to a CD was made.      1. Install Simplicity Studio     ...
Well the next phase for me has been looking a bit more in depth at the Energy Micro Giant Gecko EFM32 Starter Kit that comes included in the Energy Harvesting Kit. This has turned out to be a very impressive piece of equipment in my opinion!   So following the included instruction (I'm learning!) the first thing to do was download and install the free software from Energy Micro called Simplicity Studio. Unfortunately this is designed for Windows based computers whereas a few years ago I wis ...
As promised, here's a small video of the tool chain in action on Linux:       Used setup: arm-none-eabi compiler chain Files from EnergyMicro downloaded with Simplicity Studio; c code, CMSIS headers Code::Blocks IDE, using files from energy micro Programming through gdb is only possible when using the Segger JLink GDBServer. The gdbserver downloaded with Simplicity Studio will be able to debug, but can't program the EFM32GG990F1024 on the demo board I set up code::blocks s ...
Hi,   I would like to present the brief description of my energy harvesting project. Previous posts written by Sean and Victor made me realize that I have to be careful about what I say regarding the energy that is available from transducers. That is why in title I stated 'almost', because I am not entirely sure that I can fully substitute the battery with only the harvester as a power supply. But back to the topic … The other night I was making diner in the kitchen and I saw a b ...
When I started thinking about energy harvesting, and read about the kit, I had a very clear idea in mind what to make with energy harvesting. In the Netherlands, where I live, a lot of people ride bicycles. There's even a Wikipedia page about it! As you can read about it, there are more cycles than people in the Netherlands. However, "with great cycling power comes great cycling responsibility". The Dutch law tells that you should have a workign head and tail light on your bike. Regularly, polic ...
Hey everyone,   I too am part of the energy harvest challenge. Unfortunately I don't have my kit yet but according to tracking number it got to Australia last night so will hopefully get a hands on play Monday or Tuesday.   My original plan was to hopefully monitor my homebrewing process with it. I'm doubtful I will be getting enough heat from fermentation and CO2 emissions to monitor everything off that but will be looking at things I could do to harvest power from grain till the ke ...
Did you pick the odd one out?   There is no odd one out. These are all energy harvesting sources that have been successfully used.      The Car Fridge is Thermal Energy Generator Source      The Electric Drill is an Inductive Energy Source      The Electronic Cymbal is a PiezoElectric Source      The Drum Synthesiser is a Current Loop Source   The wires coming out of the each device are tap poin ...
Hello Everyone,   A proper unboxing is needed for such a great product and kit. But I will go with the others that since we already have a unboxing video from Wojciech Gelmuda, all of our kits look the same and I will focus on other details as everyone has.   This kit has impressed me more than any other product I have had the opportunity to Roadtest or use. The way the kit was packaged was finally what we have all dreamed of. A kit/board that needs no involvement whatsoever! You sim ...
Preface My thanks to Element14 and Würth Electronik for inviting me to participate in this Energy Harvesting  RoadTest Challenge. I've already completed a large battery of tests and experiments and over the coming weeks publish my findings and progress. Introduction Energy Harvesting is best defined as the recovery and application of otherwise spent or wasted energy. This energy is usually found in varying quantities in some obvious and not so obvious places.   An obvious e ...
Hello All!  Here's my first post in the Energy Harvesting Challenge. I'll give my first impressions of the Energy Harvesting To Go kit.   Unpacking As you have seen in Wojciech's post from today, the harvesting kit is literally 'ready to go'. The peltier and solar panel can both power the board to let the demo application run the temperature measurements. Nice! It's really fun to play around with, and I took it to my local makerspace to show around. It's really fun to see people wonde ...

First Impressions

Posted by indieflow Apr 8, 2013
Hi everyone, just thought I would introduce myself as one of the lucky few that was selected to road test and become a competitor in the Energy Harvesting Challenge.   I was going to create a little video giving my first impressions of the design kit though seems as though Gelmi has saved me the trouble! So I'll just add my two pence on the subject.   The design kit comes in a very well presented and secure case giving a nice wow factor on first impressions. The only downside to the c ...
Hello, I would like to share with you my first impression about the kit that I got for RoadTesting. In my opinion, the great thing is that just after opening the box, the kit is ready to use – you do not need to plug it into any computer to test its basic functionality. The harvesting board is cleverly divided into sections and you can employ your own transducers right away. If you do not have any, you can always use the onboard ones: peltier module (with radiator) and small solar panel. T ...
