Gemini 3 scanned photo to sketch in fusion 360

圖片
 20260218 I decided to make my essai, 1. prepare the scanned photo. to minize the angle issues with camera, I plan to use the scanned function of my cannon printer. I first try to put whole car on the scanner, and a ruler as reference the result is terrible adding some light on top to increase the visiblity better, maybe good for hand tracking in fusion 360. but not easy for sw treatement. I took down the chass part, put it flat on scanner The problem is that scanner has it's own light source, slight advance of the scanner unit, since this has about 1.5mm thickness, it create shadow on parts, you can see the round hole is not round. and some shadow on edages. I enhanced the black and put it into fusion 360: import as canvas, then using project salvado to create sketch. I found out that the rule in the image file will make it impossible to create sketch, so I redo a scan without ruler. It does work, but some problem shows. the round one is not round, and the scanned edage is not alw...

changing the polarzing film of LCD

圖片
after doing some research, I understand that LCD film can be degrade by light, then screen turn to black or blank. And there are 2 films in a LCD module, one on the top, one on the bottom with reflecting face. trick is to heat up before peel off, sometimes, glue residue can be slowly remove with alcohol. take your time, don't crape it by force, it may leave track on LCD glass. if you can light up machine after remove the film, then it's easy to find the orientation of replacement.  If not, try to find the most bright diection when 2 are stack up. it should be the correct direction. 1. 9XR RC remote nothing show on the screen, after open it, it's the top film failed. slight heating with hot air gun. nothing on the screen after changing the upper film, it looks good with external light. but the back light seems very week in dark. 2. coreless phone: this one shows nothing, my first try is to replace the back side film. JP stuff, quite delicate, can see a pop on the back side f...

 Buying thing from china is always suprising. I carefully selected TLRS chip one from  Stellar-m3n@  and skyline pro-MN@ one suprise comes in : stllar-M@ the pcb has very different testing dots and it's marked  HS_EL5102-0_V2-4  ... searching on web, there is a site mentions this is a  HS_EL5102-0 SKU:  HS_EL5102-0_V2-4 ,  HS_EL5102-0_v1-9-4 MCU:  MSP430G2755 Wireless: Amiccom  A7106 Display: ( SSD1675B )  HINK-E0213A30 SPI Flash: AH1717 25VQ21BT (256 KiB) thw owner did a very detail search on Hanshow from a chinese web site this is confirmed 汉朔墨水屏电子价签拆解（Hanshow Stellar-M）          [复制链接] njchenmin 电梯直达 1 #   发表于 2020-6-6 06:31:39   |   只看该作者   闲的无聊，某鱼上买了几个电子价签，是墨水屏的，到手迅速拆开让大家看看。 主要配置： 2.13寸黑白色EPD，HINK E0213A04；26pin fpc 焊接 ； 分辨率 250x122 mcu：msp430g2553 tssop 28pin rf：A7106 qfn 20pin spirom：25vq21b ； 256K flashrom 两个cr2450并联供电 号称能用5年 interesting, I found a TI doc talk about CC2650 and A71...

  atc1441 / ATC_TLSR_Paper     this lib works with TLRS8359, which has a 2.4G RF, and seems can be enabled as BLE. https://b3logfile.com/pdf/article/1681979425953.pdf you can find cheap Hanshow price tag from china, the git page has a list of working model. basically you look for model with an "N" Name Display Case front Case back Stellar-MFN@ E31A 2,13" 212x104 Stellar-M3N@ E31HA 2,13" 250x122 Stellar-MN@ E31H 2,13" 250x122 Stellar-S3TN@ E31HA 1,54" 200x200 The whole project repo on GitHub can be found here: https://github.com/atc1441/ATC_TLSR_Paper The WebSerial Flasher can be found here: https://atc1441.github.io/ATC_TLSR_Paper_UART_Flasher.html https://github.com/MakersFunDuck/Hanshow-Auto-Updater 1. the wire connection: RTS is needed for this: RTS - Request To Send but my ftdi has only CTS - Clear To Send

 From a boat utuber, it seems motor cycle android system is a pretty good solution for boater. some of them comes with android system 12-14, it means we can install apps we need. most of them are made in china, their map system is very different from others, so I turn to Aliexpress, their android system is the same as westen ones. This " EKIY M21 7 inch " it's water prppf at IP67, brightness is about 800 nit, with built in gps, and android 13. You can find some newer ones with larger screen and better function, I got this one with 71USD, and 3.2USD for shipping to TW, pretty good cost. shipping was very quick, package is light, no info about maker, no web site including gps antenna, power adapter is 12-24V in and 5V out with 3pins connector power: Yellow is the battery +, the red one is for key swiched power. This is the voltage measurement on the connector GND is direct connected to input GND(as most bulk converter) yellow is 5V, the upper 5V I guess: Is pull up to 5V fo...
