@Tommasocerno Nel PD: Partito demenziale

@Free4futur99001 sempre peggio, la colpa è di chi vota quell'area politica

@Tommasocerno Gli ultimi attentati furoni fatti dai palestinesi amici della sinistra. Se c'era dubbio è stato chiarito: I problemi psichici ce li hanno i politici europei

Don't forget to check out my ebooks. Some great topics are covered: Op-Amps, Superhet radio & Multimeters. They are longer than my Concise Guides (which are also available) and they also offer great value. Check them out: electronics-notes-shop.fourthwall.com/collections/eb…

@Tommasocerno Il problema non è tanto la religione quanto che i paesi che la usano vedi l'Iran sono irriformabili, non vederlo è da imbecilli

@Tommasocerno Ah perchè contano qualcosa? gente totalmente insignificante. Anzi dannosi per la pace in taluni casi

@ElecNotes Nooo. Sorry. Consider democracy will be ever limited

@pbecchi Anche a me è venuto in mente Oswald. E' la dimostrazione chiara che hanno fatto tutto da soli

Supercapacitors vs. Batteries: Understanding the Nuances for Modern Electronics Let's investigate a topic that's sparking a lot of interest in the world of electronics design - Supercapacitors vs. Batteries. What Are They? - Batteries: They store energy chemically, providing a high energy density which is great for long-term power needs. Think of them as the marathon runners of energy storage. - Supercapacitors: These are the sprinters. They store energy electrostatically, offering quick charge/discharge cycles, high power density, and an incredibly long lifespan. Energy Density vs. Power Density - Energy Density: Batteries win here hands down. They can store more energy per unit mass, making them ideal for applications where energy needs to be stored for long periods (like your smartphone or EV). - Power Density: Supercapacitors excel, delivering power much faster than batteries. This makes them perfect for applications requiring quick bursts of energy, like regenerative braking in cars or power backup systems. - Charge & Discharge Times: Batteries take longer to charge and discharge but can sustain power output over hours. Supercapacitors charge and discharge in seconds, ideal for applications where rapid energy transfer is crucial. - Lifespan: Batteries have a finite cycle life, degrading over time. Typical lithium-ion batteries might last around 300-500 cycles before significant degradation. Supercapacitors can handle millions of cycles with little degradation, offering a much longer operational life. Safety & Environmental Impact Batteries, particularly lithium-ion, can be hazardous if not handled correctly (think thermal runaway). They also pose recycling challenges due to their chemical composition. Supercapacitors use materials that are generally less harmful and easier to recycle, but they do have a higher initial cost. Applications Batteries are your go-to for consumer electronics, electric vehicles, and anything requiring long-term energy storage. Supercapacitors shine in applications needing rapid charge-discharge cycles, like in regenerative systems, short-term power backup, or as a complement to batteries in hybrid systems. Why Not Both? Hybrid systems combining batteries and supercapacitors can leverage the strengths of both: the high energy density of batteries and the high power density of supercapacitors. This approach is becoming popular in automotive and renewable energy sectors for peak shaving and load leveling. The Future Research is ongoing to close the gap in energy density between supercapacitors and batteries, potentially leading to supercapacitors with battery-like energy storage but with the speed and longevity of traditional supercapacitors. For those of you delving into electronics or considering energy solutions for your projects, understanding these differences is key. Check out more details on my Electronics Notes website for a deeper dive into how you might leverage these technologies in your designs. The article can be found under Electronics >> Components >> Capacitors >> Supercaps vs batteries

A very good tutorial #OPAMP #comparator #electronics Operational amplifier ,Comparator (Tutorial) fscdn.rohm.com/en/products/da…

In add they have: more larger difference voltage at the input a good output current(entering) open collector - pull up rough 1-10 Mohm

Should you use an Op-Amp as a Comparator? It is often tempting to use an op-amp as a comparator. They are easy to come by, and easy to use. There may also be a spare on one the PCB as these chips often come with several options-amps in a package. But it may not be the best
