USBasp - USB ISP/TPI programmer for Atmel AVR microcontrollers based on the design by Thomas Fischl. More information can be found at https://www.fischl.de/usbasp/. Windows users may need to install a driver. Of course this is not necessary for linux and mac users. If you are burning a fresh microcontroller, close the Slow Serial Clock jumper (SLOWCLK) since they are factory programmed for interna...
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.
My version of arduino with ARK connectors and better voltage regulators.
Fully working board
This version of board allow you to upload your code via usb uning CH330N microchip
Now there is also 3.3V high current voltage regulator as well as 5V
This is a miniature 0.7W amplifier with adjustable bass boost, gain, and volume controls. Uses 1/8" (3.5mm) headphone jacks on the input and output. Powered by USB or 9v (4-12 VDC, max of 15 VDC). I designed it to use film capacitors and Nichicon audio grade electrolytic capacitors wherever possible in order to preserve the signal and reduce noise. An isolated power supply such as a battery is...

The FT232R is the latest device to be added to FTD I’ s range of USB UART interface Integrated Circuit Devices. The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDI Chip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial designs using the FT232R have been further sim...
This power supply is very simple in that it derives its power from a USB socket, and allows feeding of the circuits that require 5V, is also present an integrated LM317 that with the values of R1 and R2 chosen provides in output a voltage of 3, 3V (see diagram)
The self-resetting fuse F1 protects your PC, the power supply can be switched off by pressing the switch SW1 while the lighting of the PW...
