WBo2 2Y DIY Wideband Unit

WBo2 version 2Y, introduced in February 2008, is Tech Edge's latest DIY product. Easy to construct with some pre-built and tested modules, low cost, and 100% professional appearance.

2Y on-line information will be updated throughout 2008.

The 2Y series is the first dedicated DIY controller we've offered. In the past we've offered pre-built versions of all our DIY units. We will not offer the 2Y as a pre-built, but we will not stop others from building them and offering them for sale. In fact we encourage this and intend to offer links to people who have demonstrated they are capable of building and supporting the 2Y series of DIY controller.

 Note: the 2Y1 does NOT include the 1 Mb on-board logging, this will be offered in April '08 as an upgrade module. The 2Y2 with inbuilt display will also be offered as a complete kit in April '08 ($29 more than the 2Y1).

2Y Features

The 2Y DIY controller is presented in a tough ABS plastic case. The controller is based on our original 2A0 design (thousands sold worldwide since 2003) and is enhanced in the following ways

  • All outputs and extra inputs are present on a 10 pin connectors on the side.
  • A label clearly shows the function of each pin.
  • An additional RJ45 connector gives two serial connections points (but one serial port)
  • The original 8 pin end connector is still used for the 0-5 Volt inputs, three thermocouple inputs, and an RPM input (see next image below).
  • 5 Volt power (dedicated regulator) to power external devices/sensors.

Pre-Built Modules Simplifies Construction

A feature of the 2Y controller is the use of a pre-built Lambda-module. The module is constructed with SMD components and comes factory tested, making the construction simpler and the chance of success much higher than the original 2A0.

The SMD Lambda-module is readily replaced but our experience with SMD construction suggests this will be the last item to cause problems.

Not shown in the image at right is the on-board-memory module which holds 1 Mbyte. The module is an option and the 2Y has either none, an 8 pin 32 kbyte EE memory-chip, or the pre-built 1 Mbyte module.

Option with an Inbuilt 4 Digit Display

The 2E0 is no longer available but there will be a 2Y version with an in-built 4 digit display. Some inputs are lost with the additional display, and it's often difficult to use this version on a dashboard but this is a worth successor to the 2E0 and is a lowest-cost lambda solution in a single package. and an external display can still be used.

The image shows a working prototype but the buttons to control the display are not shown.

Easy to Construct, Fewer Components

Here's another view of the unit clearly showing the pre-built Lambda-module and the connector for the memory-module (front/left of Lambda-module).

The unpopulated area to the left of the case is for the display components

Note the lower component count compared with the 2A0 (image).

Builders of our original 2A0 o 2A1 should note that the new DIY kits come (optionally) with our new DIY cable kits. The new lower cost and better quality cable kits use a new one piece cable we had especially manufactured for us. A correctly built cable will greatly enhance the duarability and reliability or your DIY unit. This is backed up by our finding that up to 80 percent of problems with DIY kits was due to problems with the cable.
