Also you have to assemble the components of the musical circuit. Clock measures 150 x 170 x 110mm Requires 3 AA batteries 1.5V R5 (NOT INCLUDED) Check all parts before beginning assembly MATERIAL INCLUDED Ref. piece Descripción Description Quantity Battery holder connector Integrated circuit M8031 Circuit board 30x20mm Transistor BC337 Adjustable resistance 470 Ohm Speaker Cast Iron PVC as the clock support Sphere silkscreened CD Needles (hourly, minute hand and second hand) Battery compartment Quartz clock mechanism Battery compartment the sound circuit Cable to connect the speaker Doublesided adhesive foam

2 C9739 Tools required to mount the clock : Drill Awl Drill Bit Ø14mm Shears Flat file, triangular file Welder Tin Flat nose pliers Cutting pliers Termofolding machine to bend the hot plastic. You can also use an iron to hair, to bend the plastic. Musical circuit The M8031 is an integrated sound generator type "ding dong", manufactured by Technologie CMOS circuit. This circuit, besides being a miniaturized component has a dithering function which needs no external components. Circuit characteristics Voltage: 1.3 to 3.3 VDC Sequentially ding dong Capsule TO92 Output to connect to an NPN transistor, which will connect to a loudspeaker 8W ohms Maximum voltage: 3V to 5V DC Operating temperature: 10 to 60ªC Maximum storage temperature: 55 to 125 C Electrical characteristics Symbol Tension Current Operation Frequency 2

8 C9739 Mounting tab E10 y E20 E10 Continuity test Material: Tester or multimeter to measure resistance or simply continuity The printed circuit sound circuit has numerous copper tracks. It is essential to check two concepts: 1) No clue has to be interrupted by microcuts. 2) There should be no short circuit between adjacent tracks. With the help of a continuity tester, check the continuity of the tracks one to one first. Then check that there is no contact between tracks. Use the drawing below to go color painting the tracks as they are verified.

Attention to the quality of the welds and not to short. E60 Solder the battery connector Material: Tweezers, soldering iron, tin and cutting pliers Black Red Check that the tips of the wire connector already soldered and insert them into their corresponding holes. Attention polarized component. The red wire corresponds to the positive pole and welded where the plus sign is marked. The black cable to the negative and welded where is marked the minus sign. Carefully solder the component. Attention to the quality of the welds and not to short. Cut off the excess wire once soldier 9

10 C9739 E70 Solder the speaker Material : Welder, tin, cutting pliers and wire strippers Black Red 1 Cut two pieces of cable 120mm2 Peel about 5mm, each of the cable ends 3 Tinning the four ends of the wires peeled 4 Solder a wire to the terminals of each speaker. Attention to quality of welds 5 Solder the wire that comes from the negative side of the speaker () to point to the right (see picture) 6 Solder the remaining wire to the other welding point showing the drawing. Remember polarized component. Carefully solder the component. Attention to the quality of the welds and not to short. Cut off the excess wire once soldier Cable Clock Solder the wires clock E80 Material: Welder, tin, cutting pliers and wire strippers Black Red 1 Peel about 5 mm, each of the ends of the wires out of clock mechanism 2 Tinning the two wire ends peeled 3 Insert the two wires soldered at designated points of the printed circuit 4 Solder the two wires to the printed circuit Weld carefully. Attention to the quality of the welds and not cause shorts. Cut off the excess wire once soldier 10

20 C9739 This kit Pedagogy The art for an electronics workshop and a working machine shop, combining creativity and research concern. It is not a closed kit, all on the contrary, is open to new practices. It is a matter of imagination. We learn about the basic operation of a carillon clock on manufacturing techniques and assembly of products and different materials, such as wood, plastic, fiberglass, welding and basic electronic components. NOTE: This kit is recommended for children from 12 years if accompanied by an adult. 20
