DEV LOG#03 ============================================================ i’ve trying to post a video of my buddy but i dont know why!!! i doesn’t work!! (maybe the file is to big) but i cant film as i’m writting because i’m not home but!!! ============================================================ so today i’ve build the extern battery i’ve go problem en BMS because i don’t buy one (i forgot) so i try to make mine in code by reading the voltage of the the BAT + & BAT- but BIG MISTAKE so i’ve got problem to lunch the program as my “safe” code was stoping the esp32 everytime (i code it bad thinking it can read voltage) i try the boot button ( it was hard to find it on my esp32) =========================================================== so i understand i have to buy 2 resistance and conect them to the BAT- BAT+ and then conect to a pin that can read voltage so i’m waiting to buy a resistance but it nothing for a delivery it will make a lot of co2 emission for othing so i’m waiting to command other thing with these pack of resistance !!!!! but the program and prototype still work on lipo but still dangerous as i don’t know the voltage !!! ===================================================================== i can’t upload anything i think my pc i broke so here’s a photo instead of a video =====================================================================edit i have cut the battery till the safe problem is done ;)

DEV LOG1
in fact i wasn’t able to use stardance before so before this i’ve past 20h making the code of my little compagnon so i rencently start to make the box
-the hardware is an little key chain i want to make that when you move a little the animation of an oled screen is some eyes moving clinging or whistle and look to the side and then when i move a lot we she a fox walking in the wood and waking up
for the project i buy an SDD oled screen and MPU6050 for the mouvement and an XIAO ESP32S3 by seeed and some equiment and ressources litte “etain” “flux” “thermo gaine” pr even a soldering tip and a LIpo batterie a litle tiny one i don’t remenbe how much mah but it’s 3.3v i thought like all the other component and button (on/off)

now i’ve finaly finish the box that will contain the composant
it was hard to make a fox because i have only primary forms and thinkercad is for basic box’s but i think for a beginier it’s not that bad! ive prepare the size of evrything and make some relief with piece i would have to glue at the lab of my town i think they have the material to make 3d thing i just have to make a abonement TT but then i will have the tools i need. i don’t to use metal so the cover of the box will be glue like we see with the rectagle !!!
and the nex t step i waiting for the component to be shipped TT
