content: I agree most of the opensource projects are for some wierd reason coded in ASM which kinda ticks me off if I want to change something but can't make heads or tales of the code I took one look at ASM and said eff that, although it wasn't until I read an example code of a PIC lighting an LED that I figured out why my c code wasn't working.

content: I lived in Italy for 15 years (happily I'm back in the UK) so I can try and interpret the names for you.I think Arduino derives from Arduo which sort of mean hardy, yea not a terrific name.I must say i spent a long time trying to wade my way through assembly being told not to use anything else, and Dave you right its bollocks ! I just wasted time thanks to some idiots, I now use mikroe basic and its great on pics, I get most projects up and running quite quickly and if microchip start being unreasonable (like ripping us off with pickit3) i can port to another chip, I'd never try assembler again, free from mind bogglness and easy to move.

The goal is to make information easy to understand and accessible for beginners, hobbyists, and anyone who loves learning.One of the sections I've included is dedicated to photography FAQs—covering basics, tips, and solutions to common problems that many of us run into while shooting. Over time, I plan to expand the content into other topics as well.I'd love for you to check it out, share your thoughts, and let me know what kind of photography questions or challenges you'd like me to cover in future posts.Looking forward to your feedback and suggestions!

But they cannot be made out of metal either because they will leave marks, damage the devices they're used on. So they have a contradictory requirements of being very tough while made of soft enough material.

content: I have this doubt suppose if you take the case of 2 pole 3 phase BLDC motor, it has got 6 stator windings, the net magnetic field will be rotating one and at certain instant say wt=0 degrees the net magnetic field is at the 0 degrees. The net magnetic field corresponds to North Pole at one coil end say "a" and south pole at the other coil end say "a'". Now consider a case of 12 stator windings 4 pole here as well we get the net magnetic field in certain direction then you should have a single North and South pole, but actually there will be 2 North and 2 South poles which i am not able to understand.

The traffic light “controller” was a custom made camshaft driven by gears and a small synchronous motor.The cams were all individually made and tailored to a specific intersection, although there were a few “standard” cams for the simplest intersections. The timing of course, was modified with different gear ratios.The camshaft for large intersections could be quite complex, and had spaghetti wiring.Thanks for the memories.EDIT; Also, the incandescent light bulbs for the traffic lights were a special type, with a higher rated voltage to provide for long life and with a rugged filament capable of withstanding the repeated switching.

Its always 1 or 2 generation stock which they buy.If anyone else made GPUs with enough VRAM to run LLMs, I would buy them. All the games that I play are from mid 2000s, for which my Ryzen 5 5600GT APU is enough for, no dGPU required. Team green has been acting scummy for quite long

So maybe its only looking at forward acceleration and deceleration with the accelerometer.Had it worked "perfectly" it would be a great device, if such a thing is possible. Banning it would be crazy.

The device uses an ATtiny13 microcontroller to read temperature from a 10K NTC thermistor and dynamically adjust the FAN speed using PWM (Pulse Width Modulation). The coding IDE is Arduino and the PWM frequency is 25KHz. The ferrite core is EE19/8/5.

content: This project presents a 24W Flyback power supply utilizing the DK125 chip, designed for dual-output operation with 12V at 1A and 5V at 2.2A. The circuit operates at a switching frequency of 65kHz, using an EE-25 ferrite transformer as the core magnetic component. Semi-regulation of both outputs is achieved through the weighting method, enabling precise user adjustments via a multiturn potentiometer to modify output voltages. The design incorporates rigorous measures to minimize ground path impedance and loop areas, ensuring efficient performance and reduced electromagnetic interference.

content: There are always compromises in every vehicle. A fully Extended Range battery Electric Vehicle has significant efficiency losses in the mechanical-electrical-mechanical energy conversion. If a larger battery is preferred, you have to reduce the size and weight of the internal combustion engine to keep the vehicle from getting overweight. This compromises the horsepower available when running on gasoline, reducing the usability of a truck for carry and towing.Plug-in Hybrid Electric Vehicles usually start from an existing gas-only Hybrid Electric Vehicle. While they usually retain very good gasoline consumption, they are compromised by the lack of space to install larger batteries, limiting the range of electric only operations.Actual vehicles are compromises between the two extremes and it is not possible for the designers to please every customer.
