Costing transistors
Log from Stick / TIG converter
this will be the third time I've started this project update.stopping due to it getting far too late in the night, needing to go to the work or wanting to go to the pub.the simple fact of this project is it can't be built with off the shelf parts at...

Everything tested
Log from Portable 100W led flashlight
Found a good heatsink and got almost all components.Still waiting for some boost converters from china.The led was first secured by wood.Now i am using alu plates and long screws.Everything holds together and won't fall apart anymore ;)Next step: waiting...

Boost converter arrived
Log from Portable 100W led flashlight
Some minutes ago the new 600w constant current boost converter arrived.Sadly some capacitors were damaged and broken off the board. duh. what a mess. Bent in all directons.This is how it arrived:Managed to solder them back on and they seem to work...

Change of boost converter
Log from Portable 100W led flashlight
It was about time i revisited this project.The boost converter i had initially was a beefy "600W" part that seemed like a good idea back then but only runs good at around 17V+. No chance at 12V to get full output power.So i got a new "250W" one that...

Problems Faced
Log from Infinity Mirror Clock
Even though this build is relatively simple, I faced a few problems while building: The dimensions of the circles are very important. As I did not have access to a laser cutter, the circles have been cut by hand (not by me) and I faced problems while...

Example Project 4 - LED stripe controller
Log from The Atmega Hearth
This project was long time on my todo list. Project cost: Below 30€:- 19,95€ for the chinese RGB Stripe, bought on 5. April 2013(!)- 30m LED stripe :-D)-

Modelling update
Log from $5 DNA Replicator
So, I guess people are wondering how this thing will work?Well, this is how the cheap version will work. The much more complex version is far superior, and I will focus on that, once I get a working prototype of this simple version built.Firstly, for...

And so it begins!
Log from Toner/Laser 3D Printer
Today I went out and purchased components to start this build. Parts list so far: Milk crate, I am going to use this for the frame as they are strong and cheap. I plan on replacing it with one of the older ones when I find one as they...

It works!
Log from Smart Battery Tester
I'm getting close to finishing this project. I decided not to add a charger IC, as it would be very difficult to be able to charge all the different types of batteries I want to support. Right now I can test LiPo/LiIon, LiFe and Lead Acid batteries....

I ain't dead yet!
Log from Smart Battery Tester
After putting this project on the shelf for months, I've put some work in and the project is in a reasonably finished state. There's more that I want to do with the software so I may work on that and post updates. I have posted the current source code...

MPPT Algorithm work
Log from Solar Energy Generator
I have been working on getting an MPPT algorithm up and running on my current test setup, which currently looks like a complete mess:You can see the converter stage, display, microcontroller, a current and voltage sensor board, and a breadboard with...

In work
Log from MOSFET Mania
Yesterday finally I installed the finished board into my 3D Printer. It works correctly with some minimal heatsink added.The next will be the test of the current monitoring.

Breadboarding
Log from Tachtastic - a fantastic Tachometer
the project started on a small breadboard on an AVR Dev board I had which used AVR ATMEGA32then moved to a proper breadboard with ATMEGA8 before finally going to the PCB..the first test with a tape on a motor and looking at the LCD for results..the first...

First Light
Log from Web Connected Hydroponic Led Grow System
Well, this week was the week that I finally got started on this project. After months of delaying this project I finally wired up the LED drivers and mounted the LED's on the heatsink. I used thermal epoxy to attach the Led's to the heatsink....

Before First Light part 2
Log from Web Connected Hydroponic Led Grow System
I was interrupted trying to catch a flight while working on the last project log. So continuing...I also found that 3 Watt 660nm(Red) LED's were slightly less costly at about $.90 each. So the LED's were within reach from a cost stand-point. ...
