Discussion about MicroPython Engineer's Pocket Toolbox [Copy link]

 

 I am going to design a pocket toolbox for engineers based on MicroPython. The main purpose is to be a practical tool, not just a development board or a learning board. Main purpose

• Combinable
• Extensible
• Controllable by MicroPython
• Easy to use
• Low cost

If you have any desired functions, please leave a comment below.

1. LCD + button + Darlington tube output 2. DA/AD needs to add buffer. You can consider configurable gain and analog switch to reserve a current sampling #You can use small resistors and instrument amplifiers or Hall 3. Auxiliary power supply expansion, +-5 +-12 plus battery charging management, #External power supply input can be used to control larger power in the future

This is good, looking forward to it

1. Keychain multimeter, using mobile phone APP display via Bluetooth. 2. Web page refresh notifier, using mobile phone to customize rules, after setting, it can run without mobile phone, connect to the network via WIFI, refresh web pages at the set time, once one or more specified web pages are updated or the update contains a specified string, it will notify the user with sound. 3. Micro-power sedentary reminder: If you sit for a long time, you should get up and take a sip, no need to explain, right? You can use sound reminders, or send reminders to the mobile phone via Bluetooth and then transfer them to the cloud. Of course, the mobile phone itself can complete this function, I haven't noticed it. 4. Electronic scale on the keychain: It seems that Taobao, which seems to be omnipotent, already has it, but it can be made smaller....

Currently, it is considered to be a main board plus an expansion board to achieve flexible expansion. LCD and AD will be expanded separately. The power supply part is under consideration, but 12V is less used, so a separate power supply expansion can be made.

Bluetooth has a specific way of use, it may be better to make it stand alone, which can be connected to the mobile phone. WiFi expansion is relatively easy, using expansion board to achieve

Doesn't ESP32 have built-in Bluetooth? I took it for granted that Bluetooth saves more power than WIFI, especially when the amount of data is not large. Of course, it is not difficult to use WIFI to connect to a mobile phone, and it should be very simple if there is an APP to cooperate.

Bluetooth is indeed more power-efficient than wifi, but the Bluetooth function is not yet completed in ESP32's micropython. At present, the main hardware platforms of micropython are STM32, nRF51/52, ESP32/8266, and the new motherboards are compatible with them.

The moderator is really amazing, he knows everything. By the way, I heard that Julia is on the rise recently, I wonder if the moderator has compared it with MP?

Julia does not support embedded platforms yet, so it is impossible to compare

It is supported, but I haven't studied it in detail.

I believe the OP knows that there are many choices of development boards or expansion boards related to micropython. There is nothing new or necessary to make your own hardware, which is a waste. I have seen the boards made by the OP's previous organization. They simply made a board similar to the ones on the market. It would be better to use this time and energy to sort out the microPython framework and make some valuable libraries and applications based on the popular boards on the market. This will better promote or let others learn the essence of microPython.

9zhmke posted on 2019-1-23 23:03 Yes, it is supported, but I haven't learned about it in detail.

Is there any introduction? I didn't see it on the official website

Some people may need to study the bottom layer in depth, while others may need to use it for development. I hope to make it easier to use and turn it into a small tool that everyone can carry with them, so as to make a pocket toolbox for engineers.

Do you mean more abundant interfaces and more beautiful and compact appearance design when you say easier to use? There are too many compact esp32 modules and many matching modules. What are the shortcomings of the ones currently on the market? What is the price range?

Although there are many ESP32 and 8266 modules now, and the price is not high, it is more troublesome to use. The toolbox is to simplify the use, and the CPU module can be replaced, and the function can be expanded. The cost will definitely be lower than before.

So it means to make a large expansion board that can be plugged in different CPU modules? Is this also your concept of toolbox? These pure drawing board jobs are unnecessary. This kind of expansion board can be replaced by other people's breadboards. After you fix the large expansion board interface, do you think that when others expand the module, they have to connect your expansion?

If this is the case, we can focus on teaching. There are so many teaching kits now, and they must be unique. At present, there is a lack of supporting resources in the field of agricultural Internet of Things in universities. We can consider developing teaching kits in this area. The Kenluobo team that used to work on Arduino is now also working on PythonIDE, and we can cooperate with them.

This is a good suggestion. We need to consider more about the application.
