The IC used inside the neopixel LED is WS2811 which is a signal line 256 Gray level 3 channal Constant current LED drive IC. Eaxh IC can control 3 outputs but the maximum current per channel is limited to 18.5mA. Which is enough for driving an LED but...
madem ("MADE-em") n. A machine capable of both manufacturing and demanufacturing a given manufactured good. Portmanteau of manufacturer + demanufacturer or maker + demaker, by analogy to modem (modulator + demodulator) and codec (compressor + decompressor...
This is simple carrier/ breakout board for fixed, static powering nixie tubes, You can select symbols/numbers with DIL switches or wire jumpers You can use this symbols, IN19A - (К, М, Р, m, µ, n, %, °С),IN19B - (S, F, H, V,T,...
A powerfull dev board with the ESPRESSIF™ ESP32-S2®, a high resolution display, a RGB LED, a battery charger and a bunch of GPIOs. There are many ESP32 board on the market but very few with the new ESP32-S2 which handles USB communications, new...
This project is sponsored by PCBWAY. It is world fastest pcb manufacturing company. You Will get FREE prototype pcb from PCBWAY. So do not be late to register and place your first order from PCBWAY If you want to order pcb...
Using its powerful Timer/Counter D (TCD), the ATtiny212/412 controls a center-tapped transformer utilizing the push-pull topology by providing complementary output signals with intermediate dead times (break-before-make time) to drive the two ground-referenced...
Briefly about architecture and instruction set - it is 8-bit design with 8 registers: 000 - 0 (always zero) 001 - A (accumulator) 010 - B 011 - C 100 - D 101 - E 110 - F (flags and 3 higher bits for jumps) 111 - G (8 lower bits of program counter) Flags...
Enclosure The enclosure is just a Billy the Bass recovered from St. Vincent De Paul's for $2.30. Surprisingly, it worked perfectly. After removing the screws to get inside, there wasn't much to change. While it's easy to remove the main electronics,...
Power Supply Specification Requirements Choose a power supply with an output voltage between 16V and 24V which can provide an output current according to the table below. The power supply must be well stabilized. The current and power is determined...
Tesla Key Watch Inspiration Before getting into the nitty gritty details of this project I want to thank two people that helped me a lot and inspired me: Darconeous for researching the Tesla Key Card protocol and creating the awesome Gauss-Key-Card...

This project is modified from the reference circuit of FP5139 switching regulator control IC. Its original design is a asynchronous buck-boost converter. To improve overall working efficiency, a gate-driver is added and use two N-Channel MOSFETs to form...
After perusing different LoRa module datasheets, I decided to employ the RYLR998 LoRa (transceiver) module since I wanted to make this project as compact as possible. The RYLR998 LoRa module provides ultra-long range spread spectrum communication with...
It is very easy to calculate the hexadecimal equivalent to a decimal number using dividing by 167 method. But this method is very long and sometimes very confusing when comes to large numbers. here I have a Arduino based decimal to hexadecimal converter....
Motor Drivers The most common type of motors you might have come across is the 3 V DC motors which are optimized to work with low voltages. These motors are hobbyists friendly and low cost. Running them is quite simple. Just connect them with two 1.5...
