K37M Kit 37M Five LED Pattern FlasherKit 37M. Five red LED's flash in seven patterns. The modes can be cycled through using an on-board SPDT switch. When the desired flashing pattern is found just leave the switch there and the pattern will remain flashing as long as power goes to the board & the switch remains set. COB PCB measuring 3cm x 1.5 cm. October 2000. Now with trimpot to vary flash rate. |

K46 Kit 46 Christmas StarNew kit which flashes 30 super-bright, red LEDs in a variety of different patterns. The patterns are read from a lookup table in a micro-controller. Electrically the same as Kit 136; it is only the lookup table and the physical layout of the LEDs which are different between them. These circuits would be impossible using normal ICs. Both circuits are used with permission from the designer, Les Grant. All source code is provided.

K 52M - Five Ultra-Bright LED FlasherFive Ultra Bright LED's flashing in random or in sequence. Uses a COB (Chip-on-board) PCB measuring 3cm x 1.5 cm. The flashing frequency is set by a single external resistor between 300K and 1M ohm. A pad connected high determines the random or sequential flash pattern. A second pad connected low determines whether the flashing is continuous or set by a toggle switch. Excellent project for schools since the project is very safe - uses 2 x 1.5V batteries, can be easily put together within 30 minutes, teaches the latest electronic technology as found in games and toys and give an strong visual result when it is finished. Comes with a motherboard to aid attaching the components to the COB PCB. Assembled Kit

K73 Kit 73 Big PIC ClockThis is a big digital clock using 2.3" LED displays for the hours and minutes. It can operate in 12-hour or 24-hour mode. The software program including a time adjustment mode can control the clock to a few seconds a year. This project was originally published in the Australian electronics magazine Silicon Chip , march 2001. The fully annotated software for the kit is available here.

K136 Kit 136 Heart of LoveA rearrangement of the Star LEDsKit 46 into two hearts. All that has changed is the software lookup table. Electrically the hardware stays exactly the same. This demonstrates the power of using a micro-controller over normal IC's. These two new kits (kits 46 and 136) flash 30 super-bright, red LEDs in a variety of different patterns. The patterns are read from a lookup table in a micro-controller. Electrically both circuits are the same; it is only the lookup table and the physical layout of the LEDs which is different. These circuits would be impossible using normal ICs. Both circuits are used with permission from the designer, Les grant. All source code is provided. We have found in recent batches of 2051's (used in the Star, Kit 46 and Heart, Kit 136) that the reset pullup resistor in the chip is up the higher end of the specification than the early ones. You should be able to reduce the reset cap down to 2u2 or 1u without problems. In more "serious" designs you would add a 100k pullup resistor which would swamp variation in the chip pullup.
