An electronic analog video glitcher is a device designed to distort
analog video signals using analog circuitry. The MisMatcher01 contains
3 different analog circuits, Sync Separator, Sync Mixer and Enhancer.
Feedback and gain controls are available for the Enhancer, as well as
a low pass lter for the Sync Mixer. To mix or attenuate different video
signals, three 5 kWpotentiometers are provided. Video inputs, such
as cameras or VCRs, and outputs, such as monitor or ADCs, can be
connected to the MisMatcher01 trough three RCA jacks. The user interface
provides users with various patch point, enabling them to interconnect
different parts of the circuit together for a vast array of effects. To easily
visualize the video signal wave, oscilloscope probe points are provided
on the main PCB.

A. BUILD OF MATERIALS

B. USER INTERFACE
Start by placing the PJ-341 jacks and solder them. Snap the gold RCA
jacks and potentiometers in place. Place the LED in the right orientation
as well as the 270 Wcurrent limiting resistor. Solder these remaining
components. The male header will be soldered later on.
To passively mix two video signals with one potentiometer, solder
a 500 W resistor from one xed end of potentiometer A to the wiper, and
another 500 W resistor from the other xed end of potentiometer A to the
wiper.
C. MAIN PCB
Start with the smaller components, such as resistors, diodes, ceramic
capacitors and the ferrite bead. Note that the diodes have polarity and
must be installed in the correct orientation. Follow this by installing the
electrolytic capacitors and transistors. These also have their own orientation,
printed on the PCB. Trim the excess leads.
Use four of these trimmed leads and solder them on the Micro USB
connection, in the main PCB. Place the Micro USB connector ush with the
main PCB and solder it to the previously soldered leads. Trim the excess.

7
Snap the three potentiometers in place along with the DIP switch and
jumpers. Solder them.
Place the LM1881’s socket in place. When soldering, jump pin 2 and
3 together with solder. Trim pin 3 off the LM1881. Install the LM1881 only
after soldering the socket.
Place the power switch, as well at the female header on the main
PCB and the male header on the user interface. Secure the two PCBs with
the provided brass screws and standoffs. With these components secured
in place, solder them.
To nish off, remove ux residue left behind and perform a visual
inspection.

8
With the 2 PCBs mounted together, connect a Micro USB charger to
the Micro USB port and turn the switch on. The LED should light up.
Connect a video source to jack A and a monitor do jack C. Patch
these 2 points together and you should see the source on the monitor.
Connect A to Sync Mixer Input and C to Sync Mixer Output. A clear image
should appear.
Connect A to Enhancer Input and C to Enhancer Output. A clear
yet sharper image than before should appear on the monitor. Enable the
Enhancer Feedback 1 e 2 on the DIP switch. Rotate the Gain, Feedback 1
and 2 potentiometers and conrm that the image changes on the monitor.
The three potentiometers in the user interface can be used to either
attenuate the intensity of a video signal, or to fade between two different
video signals.
IV. BOOTING UP
V. PASSIVE MIXERS / ATTENUATORS

The key to a stable picture is a good sync signal. The mixing,
attenuation and distortion of video signals can deteriorate sync, leading to
horizontal or vertical scrolling of video on screen. When the lost of sync
is undesired by the user, the sync separator and sync mixer can come
into play.
The sync separator, based on the LM1881, extracts the sync portion
of the video signal. The sync mixer then takes a distorted video signal
and remixes it with the sync provided by the sync separator, resulting in
a stable image.
Instead of restoring the sync of a video signal, the user can also
sync, for example, video source A with video source B’s sync, resulting
in a slow horizontal and vertical scrolling of video source A.
A two-stage low pass lter, switchable through the DIP switch, is
also built into the Sync Mixer, enabling user to create a ghostly effect.
To improve stability and compatibility with cameras and monitors, a
switchable input and output impedance of 75 Wis available on the main
PCB.
VI. SYNC SEPARATOR AND SYNC MIXER

10
This video enhancer can be used to either boost saturation and
sharpness of the video or, using the provided Gain and Feedback 1 and
2 controls, to distort the video and create interesting effects. The gain
controls how much the signal is amplied. Feedback 1 and 2, switchable
through the DIP switch, take video from different stages of the circuit and
feeds it back into the Enhancer’s input. These, along with the gain control,
can be used to create an edge detector and repeater on the video.
To improve stability and compatibility with cameras and monitors, a
switchable input and output impedance of 75 Wis available on the main
PCB.
