- We previously warned from CM4 devices that they are relatively power hungry.
We suppose it’s similar to the Pi 4 which uses a lot of power:
- The Cutie Pi which is based on the CM4 and has a 8 inch display runs 5 hours with the built in battery:
- The Cutie Pi is available for around 200 USD.
- The BIGTREETECH Pad 7 is available for around 100 USD & costs for the Compute Model 4 which is 75 USD for a 4 MB module.
- Installation of Raspberry Pi OS is tricky but there are instructions abailable.
- It offers also a HDMI out, so we could in principle replace the 7 inch screen by a power efficient smartphone and use it as a a screen.
- There are different reviews for the BIGTREETECH Pad 7.
- Most of them use it as printer screen.
- One detailed instruction is available for Mainsail OS.
- This is a a Raspberry Pi OS based distribution for 3D Printers.
- It includes everything to get started with Klipper Firmware and Mainsail.
- But we can use this instruction as a help to install Raspberry Pi OS on it.
- And Leepspvideo KDE Plasma built 4 should also run on it.
- Then we have to add a battery.
- The BIGTREETECH Pad 7 has been tested several times, for instance here:
https://www.cnx-software.com/2023/05/21/using-btt-pad-7-touchscreen-display-with-raspberry-pi-cm4
- It has also a 40 port Rasbperry Pi connector for Raspberry Pi hats.
We think it is device which is worth testing for mobile use and to see if we can optimize it further.
Information for product sellers who do stock market speculation and scalping with products mentioned by Peter Gamma on www.petergamma.org
******************************************************************************
According to the little experience of Peter Gamma from www.petergamma.org, many of the products listed here are still full of issues which need to be resolved. If you do stock market speculation and scalping with those, you will loose Peter Gamma from www.petergamma.org as a buyer of these products and as a reviewer. Is this not risky? Will you not loose a majority of your costumers as well?
And is it not so, that society in general does not accept stock market speculation and scalping with products as those which are listed here? And will you not be politically incapable of finding a majority of the voters if you do stock market speculation and scalping with these products?
And as a consequence will you not be condemned and punished by a political referendum soon? Especially if you do this to a Swiss, since are not majority of Swiss against stock market speculations and scalping with people on a budget? And people in Switzerland are known for a lot of political referendums, since we have direct democracy in this country.
And Peter Gamma from www.petergamma.org will fight up to the European Court of Human Rights against people who do stock market speculation and scalping with the products which are mentioned on www.petergamma.org. And if they do not have yet the legal basis there to do so, he will fight for it.
What is a scalper?
A scalper is someone who buys something and resells it at a price far above the initial cost. For instance some says: “He got theater tickets through a scalper”: Someone who buys tickets to an event in order to resell them at a profit. And is it not also scalping if you take reviews from this site to make out of it a new product offer, and sell it for a higher price? We doubt that you will be successful with it. Since Peter Gamma will review your product and will user not come back to www.petergamma.org after that?
