Here it is ! Using OR gate to test if the network is working properly or not. Next i will add momentum to the gradient descent and try some new cost and activation functions then I will make it use the GPU also. After these i will train it on the mnist dataset

@levelsio I couldn't either. This is probably a bug. I wonder if this is only on Android or I phone also?

Okay and who of you couldn't reply to this? Please please only if you couldn't okay?

Eid mubarak everyone 😁!

@meetingcpp Visual studio 2026 Pro😁

#CppPollOfToday: Which IDE do you use for C++? meetingcpp.com/mcpp/survey/?q… #cplusplus #cpp

@yacineMTB For those saying this is current mirror: This is a differential amplifier, the first stage of opamps.

@zackslab @LoganToddT @i2cjak I’d totally join this challenge if I wasn’t busy making my game right now.😢

@LoganToddT @BitsFlareDev @i2cjak yes! let's start a movement!

I FORMALLY CHALLENGE THEE (@i2cjak) TO AN EE DESIGN CHALLENGE (rendered in the TONE of an i2cjak wannabEE ARTICLE): ANON… I HAVE A PROPOSAL. a DESIGN CHALLENGE. a TEST of SKILL. a TEST of GRIT. a TEST of whether you are a REAL ELECTRONICS ENGINEER or merely someone who COPY PASTAS application notes written by some TI intern named KYLE. let me set the stage... imagine a world where you need to convert 12v into 48v. this is not a crazy number. this is just BOOSTING a voltage. people have been doing this since before your GREAT GREAT grandparents knew what a transistor was (i2cjack just turned 14). and yet… what does an i2cjak do? he goes to MOUSER (he was banned from digikey) and he types: "BOOST CONVERTER" he grabs some $6.37 switching regulator IC that hardly has any stock, has 87 internal op amps, slope compensation, cmc, undervoltage lockout, soft start, thermal shutdown, brownout detect, a coffee maker, and a SMALL GOBLIN that tunes the loop compensation FOR HIM. he then looks himself in the mirror and calls himself A HARDTECH ENGINEER. he slaps down one inductor, a diode, some caps, and a prayer. NO. not today anon. THE CHALLENGE: • design a 12v to 48v dc/dc converter • highest efficiency @ 10A/480W wins but there are RULES. and they are CRUEL. RULES: • NO SWITCHING REGULATOR ICS • no boost controllers • no flyback controllers • no "smart power stages" • no little black boxes that say "PWM controller" on the datasheet • if the datasheet contains the phrase "switching regulator" you are DISQUALIFIED ALLOWED COMPONENTS: • a microcontroller • gate drivers (maybe) • power transistors • diodes • discrete analog • discrete logic • passives THE CONTROL LOOP: • must be written entirely BY YOU • no OTS analog compensation network that MAGICALLY stabilizes everything YOU WILL: • fab the board at a fab house of your choice • solder it YOURSELF • measure voltages YOURSELF • measure currents YOURSELF • perform step response YOURSELF • perform load sweeps YOURSELF • measure EFFICIENCY YOURSELF • you know, REAL EE SHIT YOURSELF like the founding fvcking fathers intended. ANY TOPOLOGY IS FAIR GAME: • boost • flyback • forward • pushpull • interleaved • some cursed topology you invented at 3am i do not care. but it must convert 12v to 48v. and it must fvck. SCORING: highest measured efficiency @ 10A wins (adjusted for BOM cost). WHY THIS IS FUN: because suddenly all the stuff those nice little regulator ICs do for you becomes YOUR PROBLEM. you must engineer. ELECTRICALLY. things like: • current limiting • duty cycle saturation • loop stability • slope compensation • dead time • gate drive timing • startup behavior • transient response EXPECTED OUTCOMES: • REAL EE is harder than it looks, i might fail. you might fail. BUT WE ALL LEARN. • writing a control loop from scratch is CURSED. • switch node ringing is DEMONIC. and guess what i2cjak, the inductor you'll pick will be WRONG!!! your efficiency will mysteriously drop by 15% because physics HATES YOU!!! but, you are a MANIAC. and you will eventually produce something BEAUTIFUL even IF it is covered in your BLOOD, SWEAT, AND TEARS. so anon. do you ACCEPT the challenge? or will you retreat back to your TPS5430 application notes like a frightened little B*TCH? MAY THE SUPREME WIZARD OF ELECTRONS WIN!!!

@zackslab @i2cjak Also why not add noise measurement 😁.

@_raviguy @i2cjak @zackslab And here I am with a 10w one testing capacity of cells 😂😂

@BitsFlareDev @i2cjak @zackslab Ok, here’s 500W!

@_raviguy @i2cjak @zackslab Build one yourself😁

@i2cjak @zackslab @BitsFlareDev I only ask because it’s something I’m working on addressing 😈

@willreil @madebyjessg Get a separate mini fridge.

@BitsFlareDev @madebyjessg Bruh someone else told me to put them in the fridge 😭 I don’t know what to do anymore

Found this in my fridge, is my fiancé on drugs ?

@yacineMTB Try building a 6.5 or 8.5 digit multimeter, it will teach you a lot of things.

@oprydai Still pretty clean tho.😁

my desk is a mess rn.

@yacineMTB Good thing you didn’t step into precision analog electronics. The rabbit hole is pretty deep here. 😂

i am now an electrical engineer

@Xaraphim I am your 30th subscriber 😁

welp, im a youtuber now LINK BELOW

@yacineMTB What is wrong with that? Many developed countries have sharia law like UAE etc.

If you do not have more kids than the red line, Canada will become a Muslim Sharia law country It's just simple mathematics

@yacineMTB Yup. Can do only one thing in 24 hours properly, either game dev or hardware projects for me😥.

i need 84 hours in a day

@Jorazon1 Here is a great video from GreatScott! youtu.be/SVLGHB2IxxU?si…

@BitsFlareDev idk what that is

Was trying to meaure the motor current later, the noise gets amplified so much. I need to start with smaller motors and add a filter to it before probing it.

@Jorazon1 Nice 👍! I also need to add filters.

@BitsFlareDev Now using a 7660 voltage converter for the negative supply for the TLE2021 opamp and added a 4k7 100nF RC filter before the amp. Measurement is so clean now. Set the scope to 10x probe mode so now I can read the measurement straight from it without math at 1V as 1A.

@Jorazon1 You don't need to feed the inrush current, you have to limit it by using soft starters.

@BitsFlareDev The 24V motor should only use 4.5A, but spikes to over 12A when starting. Pictures of voltage and current using 100W vs 420W power supply. Maybe it needs a capacitor to supply the spike?
