555 timer Integrated Circuit
This gem is now 55 years old! A wonderful history is described in this vid.
Naturally I also looked in the wikipedia and Encyclopedia Britannica to find goodies of the time this wonderful timer was build. Since no patent was filed you can find a billion versions of it, which is a nice variant on the patent theme
Wikipedia states
The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics.[3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or temperature. Signetics subsequently laid off half of its employees due to the 1970 recession, and development on the PLL was thus frozen.[6] Camenzind proposed the development of a universal circuit based on the oscillator for PLLs and asked that he develop it alone, borrowing equipment from Signetics instead of having his pay cut in half. Camenzind's idea was originally rejected, since other engineers argued the product could be built from existing parts sold by the company
We are sure glad marketing was on good insticts then
The first design for the 555 was reviewed in the summer of 1971.[8] After this design was tested and found to be without errors, Camenzind got the idea of using a direct resistance instead of a constant current source, finding that it worked satisfactorily.[8] The design change decreased the required 9 external pins to 8, so the IC could be fit in an 8-pin package instead of a 14-pin package.[8] This revised version passed a second design review, and the prototypes were completed in October 1971 as the NE555V (plastic DIP) and SE555T (metal TO-5).[9] The 9-pin version had already been released by another company founded by an engineer who had attended the first review and had retired from Signetics; that firm withdrew its version soon after the 555 was released. The 555 timer was manufactured by 12 companies in 1972, and it became a best-selling product.[6]
Quite neat this was for us electronic tinkerers and engineers
The 555 found many applications beyond timers. Camenzind noted in 1997 that "nine out of 10 of its applications were in areas and ways I had never contemplated. For months I was inundated by phone calls from engineers who had new ideas for using the device."[8]

Потоковая запись ADC семплов на STM32
В этом тексте я показал как настроить потоковую запись ADC семплов на микроконтроллере STM32. ADC модель это основа любого электронного измерения. Основа любого DMM. Всё что за корпусом микроконтроллера - это аналоговый мир. ADC это портал который позволяет аналоговым сигналам просачиваться в мир цифры.

Обзор микросхемы DRV8870
DRV8870 - это старая простая микросхема управления коллекторным DC -мотором с токами в обмотках до 3.5 Ампер от компании Texas Instruments. По сути это драйвер H-моста . Причем H-мост встроен прямо внутрь корпуса самой микросхемы. Это полностью интегрированное решение. В этом тексте я произвел обзор микросхемы DRV8870. Посмотрим с какой стороны следует подходить к микросхеме DRV8870.

STM32 Tutorial #65 - Bit Banging PWM SUPER Optimized
In this Tutorial video we will dive further into timers by using a timer to bit bang PWM on a GPIO where no timer channel is available (such as PC13). We will begin by letting STM32CubeMX generate all the code but then optimize that by creating our own interrupt handler.

Timer Input Capture
In this video we'll be revisiting timers. In a much earlier video we were using Timer Input Capture to decode rotary encoders. In this video we will be using input capture mode to measure frequency and duty cycle of a pulse width moduleated input.

The long lens arrived! My first roll with my Pentacon Six is in the mail to the developer, we’ll see how the 80mm Zeiss looks. It shoots only twelve 6 x 6 cm exposures per 120 film roll. This lens is 180mm focal length, auto or manual aperture (so you can focus wide open) setting. Now to find lens caps front and rear.

💡 Automating Laptop Charging with a Simple Timer
Tired of #overcharging your #laptop #battery? I found a simple way to control charging cycles using a programmable digital #timer!
🔌 Setup:
I programmed my Electraline 58102 timer to turn on power for one hour every five hours (e.g., 00:00-01:00, 05:00-06:00, etc.).
This keeps my battery between 20% and 80%, extending its lifespan without any extra software or smart plugs.
✅ Works automatically, no scripts, no extra hardware!
