Hi

I'm a beginner at electronics. I've a aquired a "kit" with electronic components and I want tips/suggestions what fun stuff can be made with them. I would mostly like to make something that can generate sound which can be connected to a speaker but I don't know if there are enough components for this. Anyway here's the list of components (note that I've translated from another language so if something doesn't make sense please notify me):

1 Multimeter UT33D.
1 Breadboard GL 12

2 Resistors 1000hm 1 0.6W
2 Resistors 2200hm 1 0.6W
2 Resistors 4700hm 1 0.6W
6 Resistors 1.00 ohm 1 0.6W
2 Resistors 2.20 ohm 1 0.6W
2 Resistors 4.70 ohm 1 0.6W
2 Resistors 10, Okohm 1 0.6W
2 Resistors 2 22 Okohm 1 0.6W
2 Resistors 47, Okohrn 1 0.6W
2 Resistors 100kohm 1 0.6W
2 Resistors 220kohm 1 0.6W
2 Resistors 470kohm 1 0.6W
2 Resistors 1.00 Mohm 1 0.6W

2 Trimpot 72P 10 kilohms

1 capacitor 10nF/100VDC
1 capacitor 100nF/100VDC
1 capacitor 1, OuF/100VDC 5mm
1 Foil capacitor 2.2 ~ F 63 VDC

1 electrolyte capacitor 22uF/25V
1 electrolyte capacitor 100uF/16V 1mod
1 electrolyte capacitor 6.8 uF/35V 2m

1 Axial choke 10 mH 0.15 A ± 5, XHBCC-103J
1 Axial choke 100 ILH 370 mA

1 TL064CN quad JFET op DIL14
4 Operational Amplifiers DIP-8, TL071CN
2 Push Button Switch for 9V

1 1N4002 diode IA 100V D041
4 EL334RD LED 5mm red
2 EL334GD LED 5mm green
2 EL334UYD LED 5mm Yellow
1 Optocoupler DIL-4, PC 815X
2nd The LD271 R LED 18m W 950nm 5mm
1 BPW34 photodiode
1 NTC 10kohm
3 EKUX 100 m black 0.28 mm2 refers 100m roll
3 EKUX 100 m red O, refers to 28mm2 100m Reel
3 EKUX 100 m white O, refers to 28mm2 100m Reel

1 Cutter TR20M ESD
1 Battery 6LR61 GP1604A

3 ~ Transistor TO 92 NPN 45 V 0.1 A, BC 547C
1 transistor TO-92 PNP -45 V -0.1 A, BC 557
2 Diode DO-35 75 V, 1N 4148
Please give me suggestions on fun stuff that can be made from this. :)

It might be OK up to 9V or so, but at 12V or more, I agree it would be bad news. When a reversed biased LED fails, what happens? Does it fail to a short or open?

It would fail to a short, and burnout to open when the current goes up. At least in theory :D I have not done this experiment.:D:D

I've decided I want to make an audio oscillator. Could someone please help me find a circuit design that would be possible to make with the components I have?

Blowing up component is part of learning :D sounds like fun to me.




While trying to learn about LEDs, I've only burnt out 15 or so........so far.


And, those were all the 1 Watters.:cool:
I now know what they can handle safely.....only if they were exactly alike, which they aren't.;)
