Lego and 3D

I started to "play" with Lego. Well not because my friends doing this in the spare time, just because I needed something. :-)

GitHub - Making order

I started to make some order in my things. As part of this moved some of my electronic projects to the GitHub. Three project was published newly:
My KiCAD libraries: https://github.com/sufzoli/suf-electronics-KiCAD-lib

The voltage reference: https://github.com/sufzoli/suf-electronics-vr001
The UV Lightbox: https://github.com/sufzoli/suf-electronics-lb001

LED Blink 3. - Finished

I owe to myself (and to my little son) with this for a while. I've finished the Lego-sized (Lego brick not included.Some glue still needed to it) LED blink. Tonight I finally took the time to solder the remaining two parts. The two LEDs.
Here are the results:

Windows 8.1 - mired "freedom" 2.

Previously, I wrote about the problem in the Freedom Freescale development tools do not work with Windows 8.1 here.
Sience I know about the problem I wanted to jump on it with a USB logger and solve it from the Windows side.
To do this, I began to gather the necessary tools, but did not get further.
Yesterday I read here that P & E eventually solved the problem.
If there is a solution already available, use it!
I collected all the Freedom boards in the house.

And exchanged all of the software.
Together with the bootloaderrel the debug applications also new. The latter is now supports the storage and the debug functionality at once, so in the future there is no more application swapping.

Photovoltaic course 4. - Certificate

And finaly the certificate is arrived. I finished the course.

Ultrasonic cleaner

This morning I set the start my ultrasonic cleaner. 

I had a major concern with it.  If the LCD display survives the operation. If I go back in time to the appearance of quartz watches sometime in the beginning of the 80s. As I remember, the simple monochrome LCDs of this watches do not really stand the water.
It seems it the mean time this issue resolved, because the display survived cleaning.

Frequency counter V2 9. - Prototype finished

This morning (started to write this three days ago, but just finished now), I came to the end of what planed in the prototype.The device works measuring frequency, period of time and is able to display time period value as frequency with three decimal places.It already meets (and in some ways outperforms) the customer's demand.Of course, this does not mean the end of the project . I'm trying to summarize what's left:Hardware:

• The current design has a jumper/dip switch block what works, but something is not as good as it should be, because I did not think this originally well over .
• Should be handle the future expandability. This is mainly for to the control switches and feedback of those.
• It should be think over what can be done with an MCU has two timers instead one.
• I should plan some add-ons . They can also be combined circuits of the following: OCXO , power supply, input signal conditioning , input divider, control panel
• Create the plans of the production PCB.

Software:

• It should be handle if we are outside of the measurement range. Counter overflow, missing gate signal, etc. .
• Fix the time period display to always print out nanoseconds.
• Measurement of the fill factor.
• Managing different time base (eg, external 10MHz. For the OCXO it will be needed)
• Automatic measurement type selection (for low frequency period of time, for high-frequency frequency measurement)
• Displaying more accurate measurement result using averaging
• The code for the add-ons.
• Employing the WDT+ for the display handling/multiplexing

That's all for now. Question when I can deal with it again. Within a few days for sure.
