CES - Mark's new bots

This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors.

Seeed Grove - RTC $6.90 The RTC module is a member of Twig. It is based on the clock chip DS1307 which supports the I2C protocol. It uses a Lithium cell battery (CR1225). The clock/calendar provides seconds, minutes, hours, day, date, month and year information. Nidec SMD Vibra motor 1.3V DC, 105mA, 9500rpm $3.00 Surface-mount […]

We were at the San Mateo MakerFaire, and were representing for BPS breadboards. They've announced their winners, and the first place went to  Elizabeth from Houston, Texas (age 11) (and we like unicorns too): Now that we have established our stance towards robotic (roboCorns) and regular unicorns (unicornus vulgaris), here's some links. They are just […]

It's been a while since we've had this kit online, but due to some diligence we've found materials to update and re-issue it! Using the licensed "MillerEngine" (which we find to be a substantial improvement over the old Solarengine), we've changed the kit with a new black circuit board and updated documentation. Check it out […]
