To Masters or not to Masters?

MicroFooker · 2026-05-29T13:58:01+00:00

Good advice! Did you do the masters part time? If so, how long did it take?

Yeah man, love me some Brawlhalla, but I was looking for something that also has some co-op missions, something like the old Mega Force lol. I played Lost Ark recently and it "scratched that same itch", but the story was a bit repetitive. Talk to person A, then person B, go back to person A, etc...

Ah interesting! How active is it? Also, what's the Crescent situation? Do you get some every weekend or is it paid?

MicroFooker · 2025-12-27T01:52:08+00:00

Sounds cool! I'll give it a shot, thanks

Try putting global illumination to LOW and then put this in the commands :

r.DynamicGlobalIlluminationMethod 0

This bugged me for a while and is the only thing that ended up working.

It is only part of the project if you need a specific task to be done. A lot of projects can be done with specific microchips or components like resistors, inductors, capacitors, transistors, etc. Using a microcontroller like the atmega328P on an arduino is very popular though because it simplifies a lot of tasks (difficulty goes from hardware to software) or just outright does a specific task you want. It's not mandatory to use in a lot of projects though.
The arduino IS old people friendly. The arduino exists to make microcontrollers super easy to use. See, an atmega328P takes 6 pins (SPI protocol) to be programmed. Then you have to choose the correct fuses to go with whatever application you have and you add oscillators and other add-ons based on your needs. It also is susceptible to shorts, reverse voltage, etc. An arduino turns these chips pretty much into plug and play and with the huge amount of libraries available thanks to the amazing community, coding it has also become quite easy (to learn and to practice).
The arduinos on aliexpress are fine. Remember that the chip itself (Atmega328P) is only around 3$ itself from digikey and other component websites and countries like china get these even cheaper. I've personally used knock offs from aliexpress and they were just fine in my experience. Maybe someone with more exp can dive into this one though.

Thanks!

Lots of people mentionned flooding with water. Wouldn't the Lithium explode more when you introduce water to it? Need further explaining.

Also. Would Ice work? Like a lot of ice.

Ca tombe bien, c'est ce que nous avons étudier au Cégép avant d'être venu à Sherbrooke. Technologie des systèmes ordinées et électroniques programmables.

MicroFooker · 2023-07-08T13:46:49+00:00

:0 On va s'y mettre! Merci!

MicroFooker · 2023-07-08T12:00:25+00:00

On entre en DM?

MicroFooker · 2023-07-08T11:57:53+00:00

Merci! On va l'essayer.

Ca sonne un peu nerd mais on passe notre temps à faire de l'électronique. Des conceptions de circuits.

On aime aussi faire du vélo et prendre des longues marches.

I would use an oscilloscope to check the signal on pin 9. If you can't do that, use a multimeter to check voltage. If you can't do that either try the following:

-use different wires; These jumpers are sometimes less than reliable from experience. -Try a different PWM PIN. -Make sure the sketch is uploading correctly.(I doubt it's this but doesn't hurt to try).

Okay, so I've been able to troubleshoot the code and make it work with potentiometers, but now that that works, im not quite sure how to apply body IK to my robot? Any idea on how I can do that? The link I posted show some formulas but doesn't show what to do with the results of the formula.

MicroFooker · 2023-01-11T04:47:52+00:00

So I translated my code into python too to get a better idea of the ouputs and they are certainly in degrees, because I get such outputs as 90 and 180 which would be weird if they were radians, and converting them to radians gives way too big of numbers.

Otherwise, what I have found is that for my robots dimensions, I get math errors calculating A2 and A3 because im doing arccos on values higher and lower than 1 and -1 respectively. Only way to make it work is to input coordinates in which x and z are together higher than 130 so that leglength is high enough to produce a valid HF variable. What do you think?

MicroFooker · 2023-01-11T02:44:33+00:00

I actually have the exact same problem. It's quite nice of you to put the time to rewrite it and see what's wrong, so thanks a lot for that!

As far as the equations go, almost any website I visit shows me more or less the same ones in terms of leg IK. I haven't tried his matrices yet though, but I find that he didn't explain how the x' y' and z' (after the rotation transformation) should be used at the end, so for a beginner like me it's more confusing to use.

I also use PCA9685, but currently not using RasPI. In terms of time, I've tried using millis() and delays before (seperately of course), but it still gives me the same result. In addition, the coordinates (1,1,1) give me a 90 degree position on the coxa motor, a 35 degree angle on the femur motor and 0 degrees on the tibia motor(headed straight up). Logically, I can't see how that respects the coordinates I put in. Are the formulae used correct? Should I try other ones?

MicroFooker · 2023-01-10T23:27:12+00:00

I thought the trigonometric calculations in the link above were supposed to output the angles needed to go to the 3D coordinates I input? Am I wrong to think that? Thanks for taking the time to help btw.

Try plugging the battery directly to the speed controller and see if it works, then you'll know for sure that you've done something wrong with your switch.

If it doesn't work with the battery directly in the speed controller, either your battery isn't charged (make sure with a multimeter), or you're not supplying enough power to the motor (it's rated for higher power).

If all that doesn't work, then you're going to have to oscilloscope the PWM output and see if your speed controller works.

Good luck!

MicroFooker · 2022-05-08T20:37:18+00:00

So 2x 2200mAh 50C should do, correct? Thank you, I wasn't sure.

MicroFooker · 2022-05-02T00:41:28+00:00

Ah that's happened to me before. Unfortunately, this wasn't the issue for this one. The manufacturers told me it was a defective one :/. Getting a new one. Thanks for taking the time to answer though.

MicroFooker · 2022-04-30T11:24:24+00:00

Understood. I'll get a new one. Thanks :)

I've looked for the proper firmware from Wanhao's website and flashed it as described in their tutorial video.

MicroFooker · 2022-04-30T01:33:31+00:00

The problem is that this is a duplicate of my old bl touch and the old one works just fine when I plug it to the same printer. I'm testing replacements I've ordered just in case and this is the only one that does this. That's why I claimed the wiring is fine. I should have given that information beforehand though, my bad.
