Japanese wood plane (kana)

This is my first time using the Japanese wood plane (kana). 

After sharpening and setting it up, I was able to take the single-cell shavings and glass-finish the wood with no need for the sanding paper.

Baofeng UV-82C HAM Radio

Initial Programming

The following warnings will sound very negative, but you need to realize what you are getting into.

Warning 1: This HAM radio is literally useless without initial programming.
To program it, you need a computer and a separate cable with FTDI microchip (~$15 on Amazon).

Warning 2: The radio comes with the set of 21 useless frequency memory channels (maybe they are set to some Chinese stations).

Warning 3: The CHIRP software on Mac is probably the worst functioning app I have ever used. This is true for any HAM radio you will buy, but be aware that other radios may not need the initial programming.

Warning 4: To transmit with this radio you need a license, this is highly enforced and penalties are high, the exception is in an emergency situation. To use this radio to listen is perfectly legal without any license.


The best way to program your radio is to:

CHIRP > Radio > "Download From Radio"

This will bring the data "image" file of the radio to your computer.
Now, you can change the settings and memory frequencies and re-upload the image.

When connecting to the radio you will be asked to select the PORT, Vendor, and Model (see image).

For Baofeng UV-82C, I have used UV-82 setting.

Important: Change to Frequency Mode

One of the first things you will want to change is the ability to switch from the "Channel Mode" to the "Frequency Mode" in order to manually enter (using the radio) various frequencies around you.

Later, when you want to lock up that feature, you can uncheck it. For my own use, I would never lock it as you need a computer and a cable to change it, but for co-workers, family, and friends, you may choose to do so leaving them with limited channels only.

You will select a checkbox:

Settings > Advanced Settings > VFO/MR Switching (UV-82C only) 

see the image below

Once you change the settings:

Radio > Upload To Radio 
If the option above is grayed-out then you do not have a proper USB cable connection or the wrong driver.

Italy Villa Monastero, Varena, Italy on Lake Como

Villa Monastero is located in Varenna, Italy, along the picturesque shore of Lake Como. Originally a Cistercian monastery in the 12th century, it was later transformed into a villa. The site is renowned for its beautiful gardens that stretch along the lakefront, offering a variety of exotic plants and spectacular views across the water. The villa itself houses a museum and is frequently used for conferences, cultural events, and educational purposes. Its architecture and botanical gardens are typical examples of the Italian eclecticism and Art Nouveau styles that were popular among the Lombard aristocracy.

Q: What are the architectural and historical highlights of Villa Monastero?

A: Architecturally, Villa Monastero showcases a mix of styles reflecting its centuries-long evolution from a monastery to a lavish private residence. Key elements include ornate decorations, intricate frescoes, and stucco work that adorn the interiors. Historically, the villa is significant for its transformation and the preservation of its original monastic features in certain areas, alongside later additions such as the extensive gardens and luxurious decor. It stands as a testament to the region’s rich cultural and aristocratic history.

Q: How is Villa Monastero used today?

A: Today, Villa Monastero is a multi-functional site. It serves as a museum that visitors can explore to view its historical rooms and collections of art and artifacts. The villa also hosts international conferences, meetings, and workshops, particularly in scientific fields, due to its serene location and facilities. Furthermore, its spectacular gardens are open to the public, providing a tranquil setting for walks and relaxation, making it a popular tourist destination in Northern Italy.

The last poet

The wizard of the desert met a young one,

- "Who are you, old man?" asked the young one,
- "I am the poet, a student of wisdom written in words"
- "What is a poet? We don't have such among today's people.."
- "Let me read for you from my ancient book",  said the old man opening Rumi, 
- "I do not understand these words, old man", said the young one after the while.
- "Can you imagine one day your children will not know of flowers or music?" asked the wizard?
- "That would be terrible!", answered the young one.
- "This is what I feel today, my child.."
