# TeleLaunch — Multi-channel Wireless Launch Controller System #
TeleLaunch is secure radio-controlled rocket launch system capable of
-operating up to 800 pads from a single controler. A typical TeleLaunch
+operating up to 792 pads from a single controler. A typical TeleLaunch
system consists of one LCO board and one or more pyro boards.
TeleLaunch uses a two-way digital radio communications system for
### TeleLCO ###

TeleLCO controls up to 100 TeleFire banks, comes packaged in a rugged
case, and is typically placed on a table for use by the designated LCO.

+
+Note that while the photo of the prototype above gives a good feel for many
+of the system features, production units will have several changes. We're
+moving to a bright orange Pelican box, instead of separate knobs for bank
+select and pad select there will be one knob with in-built push button, there
+will be 8 continuity LEDs instead of 4, and the choice and placement of
+switches is changing.
+
+In production versions, drag races are supported with a separate normal/drag
+mode selection switch, drag mode LED, and select pushbutton. Channels that
+are included in the current drag race selection have blinking continuity
+indicators.

### TeleLCOTwo ###

+
A small LCO board capable of handling up to two TeleFireOne pyro
boards, or one channel each on TeleFireEight boards. TeleLCOTwo is ideal
for individuals or clubs that have an existing launch control system but
the two during use.
TeleLCOTwo comes packaged in a weather-sealed polycarbonate box with
-switches on one face, and BNC antenna connector and USB connectors. It
-can be placed on a table, but is typical hand-held during operation.

+makes TeleFireOne ideal for individuals, launch trailers, or for "away
cells" at larger club launches.
All high-current connections are made on the board using standard
1/4-inch spade lugs, with screw terminals for the siren and strobe. This
allows for easy packaging and quick board swaps.
+The photo above is of an early prototype, the design has changed slightly
+since then. It is still possible to package the board as shown in a Hammond
+polycarbonate box, but metal ammo boxes are a credible alternative. The two
+switches are for power on/off and safe/arm. The two cables are for DC power
+in and igniter leads out.
+
+The TeleFireOne hardware design is available from
+[git.gag.com](http://git.gag.com) in the project
+[hw/telefireone](http://git.gag.com/?p=hw/telefireone;a=summary).
+
+An alternate load of the TeleFireOne including support for data logging
+sensors from a rocket motor test stand is available as a separate
+[TeleStatic](../TeleStatic) product. A TeleStatic board can be used as the
+equivalent of a TeleFireOne when not in use with a test stand.
+
### TeleFireEight ###
+<img src="protos/telefireeight.jpg">
+
TeleFireEight has eight igniter circuits, making it ideal for use at
club launches. Larger clubs or launch site setups can use multiple
boards to organize the site into multiple banks with up to 8 rockets
All connections are made on the board using 1/4-in spade lugs for
eash packaging and quick board swaps.
+The above photo shows the unpopulated circuit board for the first version
+of this design, it will be replaced with a photo of a packaged version when
+we have a prototype completed. In the meantime, see the photo of a packaged
+[TeleStatic](../TeleStatic) board for a rough idea of what we're planning,
+except that there will be 4 AC outlets with flip-lid covers on each long
+face of the ammo box with per-pad LED continuity indicators in the top cover.

## Documentation ##
Not written yet.
Several prototype systems have been built and successfully
deployed. Lessons learned from use of those systems are currently
being incorporated into new board revisions, and general availability
-of the system for sale is expected in the first half of 2018.
