- 1 x Plastic Enclosure 150mm
x 80mm x 25mm (6" x 3" x 1") You can
really use just about any plastic box from an electronics shop
but the size mentioned is called an instrument case ..any enclosure
with a lid will work!!
- 1 x 12v Li-Ion CCTV Battery
These are available on eBay from under $15 for the 4800ma
battery up to around $39 for the 9600mah battery ..just search
for CCTV Battery (the one used here is the 6800mah)
- Electronic Components
as listed below These will be used to make the voltage
regulator and optional led battery monitor (skip the monitor
list if you don't need it!!)
- Component List for
the Voltage Regulator (you will need this to adjust
the output to suit your camcorder)
- 1 x small piece of VeroBoard
(predrilled printed circuit board) (buy a small piece as
you are only using a couple of square inches!!)
- 1 x Voltage Regulator
IC Type LM350T (if you have a small camera you can
get by with the LM317T but the price difference is minimal!!!)
- 1 x 240 ohm 1/2watt resistor
- 1 x 2K ohm potentiometer
(circuit board mount)
- 1 x 0.1uf ceramic capacitor
- 1 x 1uf electrolytic capacitor
- 1 x TO220 metal heat sink
-
- Component List for
the LED Battery Monitor (this is optional and
only needed if you want indication of the battery state)
This will also need some Veroboard but you will have plenty
left from the voltage regulator!!
- 2 x 3mm LED's (one green
and one red)
- 2 x transistors type BC547
or similar
- 2 x resistors 1K ohm 1/2watt
- 2 x resistors 3.3K ohm
1/2watt
- 1 x resistor 100k ohm
1/2watt
- 1 x diode 1N4148
- 1 x Zener diode 10volt
type BZX79C10 or similar
- Extras needed If
you would like to add an on/off switch to your pack use any
small slide switch. You will need a soldering iron, some thin
solder to assemble the little boards and some side cutters to
trim the wires. You will also need a few lengths of thin red
and black cable (couple of feet will be more than enough or
just steal some from the inside panel of an old computer like
I did!!) Don't worry too much if you cannot understand
the terminology of some of the electric parts. Just print out
the page and an electronics parts store will know what to give
you (like Radio Shack or similar)
You will also need the following
tools to do the job :
- Hacksaw
- Screwdriver
- Portable Drilling
Machine and some drill bits
- A hot glue gun and some
glue sticks or a tube of epoxy resin
- Soldering Iron (small pencil
tip one) and some solder
- A digital Voltmeter (you
can even borrow one as it's just to set the regulator voltage
for your particular camera!!)
