Hi my friend, love your channel! I'm a noob, i used to work in an EE lab, but not as a tech lol. So now I'm trying to educate myself. With your supply splitter, I cant get it to work in falstad. It might be an issue with falstad, but I have a feeling it's an issue with me. So I wanted to ask, what are the outputs? I tried 12v dc for vcc, but for the life of me can't figure out how to arrange vee and ground to get the negative output, and adjusting the pot only gets me 11.94V-60mV. Any one have any suggestions?
This is truly a clear-cut video on this subject, and I love it. However, in my situation, I seem to have run into a bit of a snag with the equation. I'm using a high-power BJT that allows a maximum current of 30 amps. In my circuit, I've measured that it absorbs about 91 watts of power (I've rounded up to 100), and the datasheet shows a maximum operating temperature of 150C. Rjc is 0.5, and I follow your rule-of-thumb value of 1.6 for Rcs. When I plug these numbers into the equation, and attempt to solve for Rsa, the value is negative. Does this just mean that there is no heat sink, on the market, that could ever be used to cool this transistor at 100 watts? Or, perhaps, does this equation only pertain to a certain range of power components? The datasheet, for the transistor, claims that it has a total power dissipation of 250 watts. This is in the "maximum ratings" section. Because I'm only considering a usage of 100 watts, shouldn't I be able to keep it cool with a heat sink? I agree, with many others, that you, easily, have the best video on this topic. Keep up the great work!
PIC is absolutely horrible for hobbyists. I only got good with it because I learned to use PICs in college and had a good TA who showed me the ropes. Even then, I switched to AVR for hobbyist projects because the support is so much better.
The step by step explanation of the Dickson pump is brilliant, it shows very clearly how the capacitors sort of "bucket brigade" their charge along the circuit
awesome video! Seeing you use a WM makes me miss it so much. I used to play with dwm, i3wm a lot. Now I just use gnome but maybe someday I'll comeback to what I prefer.
Bro, dw01 chip activates over discharge protection at 2.4v which overtimes permanently damage the battery capacity, if the load is low dw01 can destroy a liion battery in ony cycle. 2.4v is even more detrimental to.lipolys. A better chip I think is fs312f. Make a video about it, and reply me.
Hi, great video!! Aquestion out of curiosity... in the case of your discrete project, couldn't you correct the offset by adding a DC servo loop? Thank you!
Can you explain to me what are the advantages of adjusting your linker files compared to IDE and automatic adjustment?! You can still use everything when using IDE.
Im upgrading to a heat sink with a new SSR i had to replace in an infrared conveyor belt dryer. The new dryers come with heat sinks, mine failed after 19 years so i dont think i need the heat sink but after your video i realize a 50A 3-35vdc input and 24-280vac output probably needs it. Thank you
Coincidently, I just picked up a Nucleo to play with an STM32 for the first time. So this is very helpful. But I'm wondering, are there no pre-generated header and linker files for these chips? I'm used to writing code for ATMega chips in Atmel Studio, and there it provides all the various utility files. Is this because you chose to not use the STM IDE? Was that just for educational purposes, or is there some reason you don't like it? (If this was answered in the video, I missed it...)
After watching Ben Eaters 6502 series and building his breadboard kit this is a definitely a great introduction into a step into 32bit. A lot more to take in but easy enough to build on existing microcontroller knowedge to take the next step. Sounds like you played on hard mode and there's some tools to avoid some of the low level stuff you've done. But it's great to get an overview of the process and the ins and outs to really get understanding of how it fundamentally works. Love your videos
How did you find the navigation of that 1000 page manual to be? Is it as straightforward as your demonstration or does it require a lot of prerequisite knowledge to follow along? Thanks for taking the time and doing what I trust to be a complete bootstrap procedure for us.
If you are familiar with micrcontrollers, then it's not too bad. You can follow the table of contents and read through the information on the peripheral. I'd say that the video makes the process look much easier than it actually is. I'd recommend starting with something like an AVR before doing a project like this.
Haha this video is super hardcore 🫣 You have great knowledge about the fundamental working of a STM32 MCU. I like STM32 but I would never ever do my own linker files. I just use the STM32 IDE for c programming and the initial code is generated by the Cube MX. The NUCLEO boards are comparable to an arduino board. And they have a ST-Link programmer included!
@@SineLab I also use CubeIDE full package (including CubeMX, STM32 programmer etc). Thank you for approval. I'll definitely try this breakneck approach (for me) also XD 😂. Thank you for this quick start guide.
Do you know about the STM32 IDE and the Cube MX? Cube MX basically generates all the initial Code for you. When you are a beginner, consider using Cube MX as a graphical klick and generate Code tool.
Well, official development boards start at around $14, and the infamous "black pill" less than $5, and there is a lot of support, not as "wild and wooly" as some Arduino stuff. .
Professors should use your this walk-through to teach. Well said. I'm new to all of this, but I've been "grazing" info / tinkering for a year or so in my freetime, and the makefile walk @18:30 is the first one I didn't want to speed through or kill myself watching - Ty for that ^^
I want a $0.10 8-bit MCU that I can program using its own assembly language and/or C without an extra piece of hardware (programmer) and without any IDE whatsoever. Heck if it were even $2 I would take it. Just let me send some ASCII text code from whatever text editor I like to a cheap but capable MCU.
PIC: programmer (hardware piece) is expensive and obsolescence comes quick. IDE is trash .. heavy and difficult .. older more nimble version was better, but no longer supported. The chips themselves are fantastic, indestructible, capable works of art. Datasheets are done well. AVR: easy to use, internet drowns in its accolades, fanbois, and docs. Any 80 iq newbie from any random 2-bit country can put together a usable widget using an arduino. The chips themselves appear to be fine to great. But the usual packaging leads noobs to look for software solutions where they should be learning hardware components and capabilities. Most of the projects I have seen using either could be replaced with <$.0.50 worth of 555 or op amp or both including supporting components. Maybe that is bc a lot of YT projects are of the proof-of-concept variety, idk. But point stands. Nice vid, though, I appreciate you making and sharing it, and I enjoyed it. Thanks.
The Pickit3 and the MPLABX are buggy, but at the end of the day they float the boat. The PIC-based end products always worked really great, I've been developing such products since 2016 with great success in low cost, low power consumption, versatility and reliability. I've seen no need to change uC families so far!
Why is the RU-vid algorithm showing me this video after a long time, it should've shown me when I needed it !! Intuitive and Infotainment. Thanks a lot, bruv!
Thank you for this. I'd love to see some comparison regarding RF immunity. I've seen problems with the LM358 where it appeared to rectify an RF field which then causes problems in an audio circuit. I'm sure a resigned circuit with better shielding would work, but the quick fix was to switch to a TLO72 or TLO82.
I'm looking for a wireless USB extender, that is, one part acts like the male "A" end, the other acts like the female "A" end, and they connect by radio link. Neither the host nor the appliance know it's there. It would appear to be a cable, except the female/appliance end would supply the 5V power. Can you please point me to such a device?
Nah, if i use something i just need to know what happen. So before just using stepper driver ic i just want to try manual mode. But, i am too lazy to make my own h-bridge so i use ir2110, then i was too lazy to calculate deadtime so it was ir2153😆
Should feeding the output of the first Inverter to both a buffer and another inverter to get rid of the time difference between the first stage and the second stage out of the equation?
