Summary of Contents for UNIT UNLIKELY THE LUNCHBOX
- Page 1 READ this manual Read it carefully. Questions? E-mail: info@unitunlikely.com...
- Page 2 Check whether you have got all the parts as pictured below. If not Contact us at: info@unitunlikely.com. in case your printed circuit board is not white you might have a different version of the lunchbox. This manual can be found at: www.unitunlikely.com/manualblackedition.pdf...
- Page 3 note the pcb amount: 1 This board is called a printed circuit board (PCB for short). The side pictured below will be refered to as the top side. The legs of the components will be sticking out from the down side. North side west Side east Side...
- Page 4 note resistor 1k amount: 5 It does not matter in which direction you solder the resistors. Components that have this feature are location: R1, R2, R3, R4, R5 called non-polarized. The resistors have color codes to indicate their resistance. Super convenient! Find the 5 resistors with the color code Brown-Black-Red-Gold and solder them on locations R1, R2, r3, r4, r5.
- Page 5 note Resistor 10K amount: 2 These resistors are color coded with Brown-Black-Orange-Gold stripes.s location: r6, r7...
- Page 6 It lets current go one way, but not the location: D1 other and will protect the more sensitive components of the Lunchbox if you connect the battery on the wrong way. The diode is a polarized component. This means that the direction it is soldered matters.
- Page 7 note IC sockets amount: 2 Solder the Sockets on the places indicated by IC1 and IC2. Mind the visual indication on the PCB and location: ic1, ic2 try to match it with the sockets. In case you didn’t, don’t worry it is more a convention in electronics than a crucial thing to safegaurd the Lunchbox from working.
- Page 8 note capacitor 10nf amount: 1 there are three similar looking capacitor but only one has the digits 103 printed onto it and it should location: c1 be slightly smaller than the other two. This is the capacitor you need to solder. The component is non-polarized.
- Page 9 note capacitor 100nf amount: 2 these capacitors are slightly bigger than the previous one. The digit 104 is printed onto them. location: c2, c3...
- Page 10 note amount: 1 A LED is polarized. if you look closely, has one flat side which indicates the negative side (-). Match the location: LED1 flat side of the LED to the flat side of the print on the PCB. Another tip: The long leg within electronics often indicates the positive side (+).
- Page 11 note amount: 1 The LDR is a resistor that varies in resistance when it catches light. The LDR is non-polarized so it can be location: LDR soldered in either direction. Please make sure that you do not solder the LDR to tight on the PCB but make sure that a small part of its legs still stick out so that you can eventually bend it in the direction of the LED.
- Page 12 note potmeter amount: 3 Note that you have four similar looking components, however only 3 are 1M, the other one location: pot1, pot2, pot3 is 100K. The values are recognizable by the white print on the top. The text on top of this compenent should start with...
- Page 13 note potmeter 100k amount: 1 This is the other potmeter. its text on top should start with 100k. location: pot4...
- Page 14 note battery clip amount: 1 Solder the Battery Clip’s red wire to the VCC and the black wire to the GND. location: vcc + GND The battery that matches this connection is a 9V.
- Page 15 note headphone amount: 1 Solder the headphone connector onto the location marked on the east side of the pcb. location: right side of the pcb Now give the PCB some time to cool down! The following components are sensetive to heat. A PCB stays hot a short while after you soldered a component.
- Page 16 note elco 1uF amount: 1 The negative side of the capacitor is distinguished by the grey stripe that has been printed on the location: c4 side of its casing. Another tip: make sure that the longer leg of the component goes in the hole marked with a plus. Note that you have two similar looking capacitors look on the writings on the side for the right one.
- Page 17 note elco 22uf amount: 1 It is crucial that you solder this components on correctly in order for the circuit to work. Give location: c5 component time to cool down before progressing to the next step. This component should be dark blue (/purple) with a light blue stripe on its negative side like the elco from step 16.
- Page 18 note ne556 amount: 1 Put the NE556N IC in the socket soldered at location IC1. Make sure that the small gap of the location: IC1 NE556N IC is on the left side and matches the gap of the drawing on the PCB. Tip: if the legs are too wide, gently bend them inwards before pushing it in its socket.
- Page 19 note ne555n amount: 1 Put the NE555N IC in the socket soldered on location IC2. Make sure that the small gap of location: ic2 the NE555N IC is on the left side and matches the drawing on the PCB.
- Page 20 note knobs amount: 4 Click the knobs into the potentiometer. Push till they make a clicking sound and they are nice and location: pot1, pot2, pot3, pot4 secure.
- Page 21 The casing of the lunchbox is also its casing. To transform this cardboard box in the most awesome casing simply punch out the circles. They are partly pre-cut so a simple push of a pencil should suffice.
- Page 22 note admire length: 20 seconds Optional but deserved. Wow, look at that awesome musical instrument you just soldered. Simply plug in a 9v battery and you are good to go!
