1. Neat. I had a Casio tv-21 from childhood. I want more.

2. Hi Fran,

   As soon as I saw this TV I grabbed my Elvis Costello album "This Years Model" because I was sure at first glance that I had grown up never owning one, but saw it often. It's in the album's sleeve cover and shows a rubber glove hand holding this TV with what appears to be Costello and the Attractions playing Radio Radio on stage. To funny. I haven't looked at that sleeve cover in 15 years until now.

3. I enjoyed watching the tear-down, but I betcha you could easily replace the batteries, clean up the corrosion, and snap the boards back together and see if it works. The plastic parts are another issue, of course!

4. I remember the Sony Watchman models. REALLY wanted one, heck, still would love one of the mini TVs.\

5. I don’t know what Brand of tv it was but I remember as a child in the hospital having bedside TVs of a similar size and type and they when with the patience around the hospital because they were connected to the hospital bed it’s self

6. THAT, was a lot of fun! Thanks, Fran!

7. Sir Clive had an obsession for miniature TV's. Nearly as bad as his obsession for the 3 wheeled battery vehicle the C5. He truly was a mad genius. Iconic design aesthetics but built to Hong Kong standards of the day, everything fell to bits. I still have several Sinclair items, the watch being the worst, 3 calculators that feel like they are made of polystyrene, a tiny radio earpiece and some measurement equipment.
   Sinclair could have been massive with a few tweaks to design and quality but he seemed very OCD about the wrong things.

9. Clive Sinclair is a kinda hero. More Sinclair!

   For a show an idea I discussed with Chat GPT…

   can i make a logic circuit with ONLY diodes?
   ChatGPT

   Yes, you can create simple logic circuits using only diodes. Diodes can act as logical gates by allowing or blocking the flow of current based on their properties. Here's a basic overview of how you can use diodes to create logic gates:

   AND Gate: You can create an AND gate using diodes. Connect two or more diodes in series, and the output will be active (allowing current to pass) only when all input signals are active.

   OR Gate: You can create an OR gate using diodes as well. Connect two or more diodes in parallel, and the output will be active if any of the input signals are active.

   NOT Gate: A NOT gate can be constructed using a diode and a resistor. When the input signal is low (0V), the diode blocks current, and the output is high (1).

   These diode-based logic circuits are quite basic and have limitations, such as voltage drop across the diodes and slower response times compared to modern integrated circuits. However, they can serve as educational examples of how diodes can be used for basic logic operations.

   For more complex logic functions and faster response times, integrated circuits like logic gates (using transistors) are more commonly used in modern electronics.

   Fran, do it. I double dog dare you. It would be fun!

11. I remember he was first trying to get a portable TV out in the 60's. There was a picture in either Practical Wireless or Wireless World.

13. A quick google search for the service manual revealed a document that has step by step instructions for dismantling the device.
