CircuitGizmos provides products for sale that are designed and produced by the creative minds at CircuitGizmos, USBmicro, Amber Waves Electronics, and other fun sources of clever engineering.
Here you can purchase the USBmicro U401 and U421 USB interface that has support for SPI, LCD, 1-wire, stepper motor control, input, and output.
CircuitGizmos sells the Maximite Computer in the form of the CGMMSTICK1 that you can add as a module to a circuit board or you can use it with a solderless breadboard. The Maximite runs BASIC and supports a display on VGA. A keyboard can interface to the Maximite as well as I2C, SPI, and serial devices.
CircuitGizmos also sells the unique USBPIR USB motion detection module and home automation and security software made to work with these devices. Other CircuitGizmo items include the DS1822 temperature sensor, relays, LEDs, resistors, project boxes, small screw terminals…
CGCOLORMAX2 - Color Maximite Retro Computer
CircuitGizmos is offering the CGCOLORMAX2, the CG version of the Colour Maximite designed by Geoff Graham.
This version of the design includes all of the new features of the Colour Maximite, plus a couple of additional features. The CGCOLORMAX2 has a support for RS485 and dual RS232 circuit that the end user can wire as needed. CAN (Controller Area Network) circuitry is also supported. For any of these serial interface circuits, just add the driver chips. The board also features a prototyping area where additional circuits can be mounted. Board size is 5.7" by 4.0". MMBasic version 4.5.
The front edge has provision for a full-size SD card. Back of board has keyboard connector, Maximite expansion header (2x13), color VGA, USB, and DC input.
Inside is a populated RTC circuit, the passive components for the serial circuits, and room for an Arduino shield.
Also on the board is a prototyping area - a sea of holes - for user circuits. You can add your interface circuits to the board itself, without having to wire up a board to plug into the Maximite connector. (Assuming your circuit fits in that approximately 6 square inch space.)
The CGCOLORMAX2 includes the features of the Colour Maximite:
The Color Maximite is a small and versatile computer running a powerful BASIC interpreter with 128K of working memory.
It will work with a standard VGA monitor and generate eight colours (black, red, green, blue, cyan, yellow, purple and white). The Color Maximite is the latest member of the Maximite family and brings new features including color, stereo music synthesiser, Arduino compatible I/O connector and a battery backed clock.
It also has all the features of the original (monochrome) Maximite including input from a standard PC compatible keyboard or USB, built in SD memory card, BASIC language and rear panel I/O connector with an additional 20 I/O pins.
The CGCOLORMAX2 can be powered from USB, but also comes shipped with a screw terminal connector and a 5.5/2.1mm barrel connector for powering from 8-18VDC. Either the screw terminal or the barrel connector can be soldered in place for the power supply input.
Because of the import restrictions of some countries, the RTC battery may not be included.
