Practical Energy HarvestingI'm now back in my Lab and able to lodge decent posts.Here's a dual purpose Car Port - It keeps the shade off the cars and also generates power.Plenty of power for an EFM32!
In this post I would like to describe what the code does when the chip is woken up once a minute or when the TEST button is pressed. I will mention only the most important parts of the code. If you would like to investigate it more, you can check sou...
The last post was very short, just a picture of the layout of my board, becaus I really, really, really wanted to get into my bed. Which I did. I will now describe what I've done the last few days. Datasheet readingIn my second-last post I point...
I finished writing and testing the code for my project. I do not know if you remember, but in one of my previous posts I measured the average current consumption of a simple, cheap CO detector to be around 500 uA (@3,3 V) – that is being consumed by ...
Whow! It was great to see so many Polish developers joining the "Energy Harvesting: Intelligence and Efficiency - In Touch Workshop" in Krakow this Tuesday! Thanks! Please share your experience here that other Europeans are considering to join t...
Hi All, This is just a note to say that I'm still working on this project and that I have some interesting pictures about Energy Harvesting.I have found a few teething problems with Windows that has prevented me from posting blog entries.As soon...
Hell yeah!I finished the schematic and layout of the board. Tomorrow I have very little time, so I'll try to update y'all on friday night what the rest of my plans is.....
Hello All, After my previous post, about having worked to get something finished before 12th of June, where it should have been July, I've started designing my schematic and PCB. Somehow, this process always takes more effort than I see upfront....
Becoming DerangedIn addition to the Expansion connector on its right hand side the STK3700 has perimeter peripheral and signal pins that can be used for connection.To use these easily I soldered on some gold connector pins. To enable the connect...
IDIOT - Intelligently Designed Internet Of Things.Rather than just a single product I am submitting a family of products for the Energy Harvesting Solution To Go Challenge.I've aptly named it the family the IDIOT to mean "Intelligently Designed Inter...
D'oh...I thought the challenge ended on the 12th of June, where it was the 12th of JULY.Which gives me a month of time to continue, where I hade been working quite hard to get a working demo on time. D'oh again. What now?I'll invest ...
As promised I uploaded the video from the tests. Because I do not have a special equipment to test the sensor with the exact ppm value gas concentration, I wondered how to create CO gas in home conditions without risking CO poisoning. I came with thi...
To sense carbon monoxide concentration, I took many sensors into consideration. The one I have chosen for my design is TGS 5042 from Figaro.There are 3 main reasons that this sensor is perfect for my application:This is an electrochemical sensor – it...
Yes, real eggs were harmed doing this experiment I took last night:players.brightcove.net/.../index.html What I forgot to film:Tasting it! Although the part of the yolk wasn't as firm as I hoped it would be, the egg as a whole was very tasty...
Slipping into GreeceHere's just a short post to inform everyone that I've just in arrived Greece after a fantastic week in the UK and Germany.I shall post more details about this soon. For some reason my last blog post fell of the radar.It was t...
Harvesting: the final frontier... It feels like I've just manouvered my egg-spaceship to a place that had to be explored; after months of travelling through low-power switchmode fields and changing my warp-core throug all low-power modes I finally pu...
Calibration - resistance270 Ohm - 253 = -6%1k2 Ohm - 1188 = -1%15kOhm - 15000 = 0%120kOhm - 114503 = -5% With 5% resistors, I think this is pretty good; probably the error is distributed between my measurement and the resistor ...
I am still developing my project. It is not ready yet, but I would like to share with you two things. The first one is the plot of TEG voltage just after I turn off the hot water tap.This data is when the TEG is under load (STK temperature demo). The...
Ancilliary Energy Storage UnitAs mentioned at the end of Part 001 the EHSTG kit comes with a bank of capacitors can be configured as VSTORE for the LTC3108 TEG energy harvester or as an energy storage bank for the outputs of then energy harvesters (i...
On the Road again.Just a short note to say that I'm just about to embark on a visit to Europe.I will be taking my Energy Harvesting Solution to Go kit and associated paraphernalia and am in the midst of finalising my preparations.Being without my lab...
See the title; I'll be going off-topic. A bit. Why bother (or: how does this relate to the Energy Harvesting Solution)?The reason I'll be looking into the physics of boiling an egg is that for this energy harvesting solution I wanted to make somethin...
Energy Harvesting SignageIn addition to the Energy Harvesting TV Remote Control and Beating Heart here's another design that I think will be basis of many incredibly useful devices.The design consists of three main components; ...
Hello! It's been a bit silent in the Energy Harvesting Blog lately, I think everyone is trying to get their harvesting going... I'll let you know what I did last week Trade fair:First, a few very dodgy pictures; I went to the Electronics an...
Great advancements wth printable solar cells Everyone thinks that 3D printing is cool but Australia's CSIRO (Commonwealth Scientific and Industrial Research Organisation) has just received a machine that is able to print solar cells.This technol...
Just today, I saw this tweet from EHJournal: The link is here, it's a project that uses the force of the heel strike to generate energy. In fact, it looks a lot like this link I posted earlier. Again, a lot of gearing is necessary for this ...
