Vacuum Pump-1 Kit
This is a nice
vacuum pump for Pick & Place
SMD or small parts. It
supplies a minimum of
-1.5 PSI of vacuum, enough to lift
and hold
all small SMD as resistors, capacitors, diodes,
transistors
and ICs up to SOIC 16.
It comes with 6 ft
long silicone air line
(not cheap pvc line) for better flexibility
and
handling, and a pickup noozle (serrated
stainless steel
18 needle). Runs directly on
127vac with no rotating
parts, no oil required,
runs very quiet.

Small Serial LCD (SS-LCD) (less than 1 inch)
Uses only 2
wires to communicate with the
microcontroller.
Segments are stepped in
using Data and
Clock pins, as a shi\ft register.
Very low power
and high speed, high contrast.
The left 4 digits
works nice, the 5th digit has
manufacturer
problems and segments are
mixed up, can
keep it blank though.

HD44780A00 controller on board
Dark Blue
text on light green or silver
background. 14 pins interface, the most usual
interface to any microcontroller. Connector with
female
posts.
Those displays are USED, pulled
from working equipment. All units are tested
before shipping.
Here is your opportunity to build that tester,
indicator, learning unit and so on.
This units work with 8 or only 4 data bits at
the interface, so you can build a simply
connection using only 7 pins.
