Q-axis

最近做了一塊板子, 用了 ST 3軸gyro, Acc, Mag sensor, 再加上ATMEGA 328, 手工上件, 死了一堆sensor....
http://code.google.com/p/q-axis/
這是做來玩的, 算是為了喝牛奶養一群牛的案例吧....


四軸我想做輕巧米你的, 先從網路上買了motor間距14cm的機體, 可是單層的結構讓振動在3S實很嚴重, 再加買一層結構, 讓振動減少.....
那個槳我也是在做過平衡的, 改天再寫一篇如何平衡

這是所用的電裝:

不含電池還是爬上了這個重量:




電池用我的3S 850mah

後來想到用碳刷馬達跟電池也許可以做得更輕巧....無刷馬達跟電變是很重的....

用了LEGO, 應該有機會再少一點, 用N channel MOSFET做了PWM的碳刷電變, 配上小電直的7mm motor減速組.....


由於當初設計時, 飛控板是可以跑3.3V的, 所以打算用1S來做動力....
一切運作正常....
到模型店買了小的正逆槳才發現這個槳真是太爛了, 完全不平衡....

跑到GWS,最小的反槳只有5030, 平衡有好一些, 但是就算剪過還是大了些....

不知道是槳太大造成重拖或是還是太重了, 用1S只能勉強浮起來....
2S,可以飛起來, 但是馬達很快就有燒焦味了...



下一步應該是改輕一點, 或是改更小的無刷....

Heltec ESP32+OLED+Lora, hardware testing

圖片
you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-S...

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

圖片
I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which m...

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The...
