firmware K148 (T1) - Simple Photographic Time

This timer was developed after an enquiry from a hobbyist who wanted a simple 60 second timer when printing photographs. At the end of 60 seconds a beeper or buzzer would sound to indicate ‘times up’. After some discussion about other photographic uses it was decided to add some extra ranges as well. We also decided on an open collector style output rather than an on-board buzzer. This enabled the kit to drive other
devices such as relays, making it more useful in other applications. Please note this item requires the CPS148 to work. This is only the firmware chip for CPS148.

IR Door Minder

This kit uses an infrared (IR) beam to monitor door & passage-ways or any other area. When the beam is broken a relay is tripped which can be used to sound a bell or alarm. Suitable for detecting customers entering a shop, cars coming up a driveway, etc. The IR beam is very strong. Distances over 25 yards can be monitored with this kit. A 12VDC unregulated supply is required to power the kit. A 12V wall adaptor is fine. Only one power supply needs to be used to power both units. The relays in this kit are rated to switch mains voltages. With power applied the relay is normally operated and only releases when the beam is broken. The relay contacts labelled “NO” (Normally Open) and “NC” (Normally Closed) refer to when the relay is released. The plastic tube is to put over the IR LED to direct its beam. This is needed when the barrier is only a few yards apart. IR transmitter PCB size:: 45mm x 30mm (1.77" x 1.18")
IR receiver PCB size:: 50mm x 48mm (1.97" x 1.89") (CPS130)
