**Breadboard friendly dev board for ATmega328P-PU (DIL-28) with NRF24L01+ (optional)**
Version 1.1: rotated NRF24L01+ 90° to prevent EMI packet loss
- Designed to run at 8MHz (with ATmega328 internal oscillator, no external crystal)
- MCP1700T-3302E/TT (250mA) voltage regulator with low quiescent current for battery operation
- With header for FTDI programmer (e.g. "FTDI Basic Breakout 3.3V")...
I made this schematic for the Arduino Nano 3.2 to be as close as possible to the official schematic found [here](https://www.arduino.cc/en/uploads/Main/Arduino_Nano-Rev3.2-SCH.pdf). I chose similar components as on the official Nano. This does mean the schematic is a bit weird, as the resistors, for example, are merged into resistor arrays, meaning I had to make some jumps to the arrays. The PCB d...
Arduino-run board that performs MPPT functionality on a power input to maximize power production for solar panels, wind generators and TEGs, and then regulates to 18V.
Input: 1-120VDC @ up to about 100W (10A max current regardless of voltage)
Output: 18VDC @ up to 10A (max 180W)
Simple USB ISP programmer for Atmel AVR microcontrollers. More information can be found at https://dicks.home.xs4all.nl/avr/usbtiny/. Windows users may need to install a driver: https://learn.adafruit.com/usbtinyisp/drivers. Of course this is not necessary for linux and mac users.

Shield for blue-pill compatible boards.
Allows to connect a second blue-pill as ST-LINK.
May use with blue-pill compatible boards on stm32f401 or stm32f411 (black-pill). For example see https://msalamon.pl/pogromca-bluepill-nadchodzi-nowe-czyli-blackpill-z-stm32f4/
Uses MOSFETs to intialize power and maintain power by HIGH output on PD7. Initiated by trigger-switch momentary closing.
Circut includes NRF2401 to transmit trigger event and battery status to listening unit.
Self power-down with PD7 LOW.

# 1. Overview #
TinyLoad is a simple electronic constant current dummy load. The ATtiny85 measures voltage, current and temperature of the heat sink, calculates power, energy and battery capacity, controls the fan and displays all relevant data on the OLED. The button is used to switch between power/restistance and energy/capacity display.

TinySolder is a simple T12 Quick Heating Soldering Station based on the ATtiny13a featuring in 700 bytes of code:
- Temperature measurement of the tip
- Direct control of the heater
- Temperature control via potentiometer
- Handle movement detection (by checking ball switch)
- Time driven sleep/power off mode if iron is unused (movement detection)
- steady blue...
This projects is a device controlled thru i2C, it has a set of instructions to control two leds, two buzzers and a combination of them.
The device uses an ATTiny85 and it connects to an RaspberryPi to send the commands.
The instruction for the device are:
- 0x00 --> Does nothing
- 0x01 --> All Buzzers ON, All LEDs OFF
- 0x10 --> Al Buzzers OFF, All LEDs ON
- 0x11 --> All Buzzers ON, All LEDs O...
TinyKnob is a rotary encoder with a USB interface based on the ATtiny45/85 and the V-USB software-only implementation of USB1.1 devices on AVR microcontrollers (https://www.obdev.at/products/vusb/index.html). The example code implements a volume control knob for PCs which works without installing any driver by acting like a generic HID device.
