Power Electronics Applications in Renewable Energy Systems: Harnessing Sustainable Power Sources
Hacker page by Avi Gupta
Introduction: Renewable energy sources, such as solar and wind power, have gained significant attention in recent years due to their potential to address the challenges of climate change and reduce dependence on fossil fuels. Power electronics plays...

Tiny Solar Energy Module (TSEM)
Details from Tiny Solar Energy Module (TSEM)
Ideal for indoor applications The AEM10941 harvesting IC is very suitable for indoor applications because it has an ultra low power startup. The boost converter starts at a very low 380 mV input voltage and 3 uW input power. The IC gets most power out...

Solar harvesting into supercapacitors
Details from Solar harvesting into supercapacitors
I designed it because I took part in the HackadayPrize2018 Power Harvesting challenge with a 1x1 inch Tiny Solar Energy Module and found a lot of interest in selling it. However since most projects have different power demands and people want...

DeepPlankter - Autonomous Drone Boat
Details from DeepPlankter - Autonomous Drone Boat
DeepPlankter An autonomous wave and wind propelled drone boat. It uses free energy in the surrounding environment to sail for a very long distance. It relies on in-air free-rotate wing and the underwater wings to provide propulsion and solar panels to...

Most Wanted Hackaday Top 10 Lists
Log from Analyzing the Hackaday Prize 2015
(Spoiler Alert: This may contain the future finalists)This was easy to put together from the last log. The views:skulls suggestion was not as helpful as expected, but I think the last list "Top 10 Number of Times in Top 10 Lists" is a good indicator...

SEPIC
Log from $1/W True MPPT
Many moons ago I worked at a company who's quotidian routine included explosions of large capacitors and MOSFETs. During such inevitable mishaps my colleagues and I would meet up around the carnage, and after extinguishing the flames (literally), we...

Characterizing the Buck Converter
Log from Solar MPPT Charger for 24/7 "IOT" devices
First up, the latest revision. Small changes from the last version including tightening up various current loops in the buck converter and moving the battery-side transient TVS diode to the anode side of the reverse-polarity protection diode to...

Slow but steady
Log from Internet of Plants
So progress has been slow over the last few months but we have been figuring out the best solutions.Sensor-wise we have found these from AliExpress: http://www.aliexpress.com/item/Protection-type-temperature-and-humidity-sensor-temperature-and-humidity-sensor-built-in-sht10/1650578403.htmlFor...

OpAmp Be Gone
Log from $1/W True MPPT
Wait a second...I just finished uploading my latest project log, and it got me thinking. Maybe I can get rid of the OpAmp altogether and still successfully implement over-current protection.Here's the thought. The way the latest SEPIC design implements...

1 Square Inch of Power
Details from 1 Square Inch of Power
After using these fantastic little ICs in my rock (see my other Hackaday.io project!) I thought that they would be perfect for the square inch challenge.Taking further inspiration from "The Signal Path" vblog (http://thesignalpath.com/blogs/2013/01/03/tutorial-and-experiments-on-energy-harvesting-ics/)...

Image tweaks and build plans
Log from A diy solar car for $12k
I changed the wood finish to a dark cherry and made some better scene renders, which I hope are a little more pleasing to the eye than my earlier Sketchup exports. As far as building this thing, first I need to move my family back to the US from China...

"Hello, World!"
Log from SLoRa - Wireless weather station for agriculture
With wireless communications a first "Hello, World!" program can be quite difficult to achieve since it requires not only working IDE and correct setting for programming with only a few lines of code to light a LED but also correctly formatting and sending...

PCB's Back & functioning unit!
Log from Open MPPT
PCBs!I received the PCB's back from SeeedStudio this morning and naturally had to build up one to test the design.As I was populating the board I realised my main mistake on the design, which was to use a completely too tiny diode package, which is why...

Advanced configurations
Instructions from Electric Heart
There are a few more advanced configurations you can add into this circuit in order to expand its abilities: Proportional feedback: You can change the comparator configuration of the feedback system to a proportional amplification system to allow more...

*tap tap tap* This thing on?
Log from Electric Heart
So as you may have guessed by this project's feed entry, I didn't just start work today on it, but since I managed to get four days off in a row from work I'm declaring the next few days to be my own personal mini-hackathon for this power supply project,...
