+  <p>OLED display replacement for HP's legendary 34401a 6½ digit multimeter.</p>
+---
+
+Many of the old meters in 34401a series are still in great working condition,
+however their aging VFD displays are failing in various ways. Low contrast,
+leaking current in segment drivers, shattered glass are frequent cause of
+these excellent devices being written off.
+
+While replacement VFDs are still sold on some markets, they are not cheap and
+getting them intact in mail is a lottery. Also replacing the VFD itself does not
+always resolve the issue since in some cases it's the driver IC that is at fault.
+
+On older issue 34401a meters (fw version 06-04-01 and prior) have a custom HP
+designed micro controller with integrated high voltage VFD driver which is not
+obtainable, unless bought as a whole front panel assembly, which again is not cheap.
+
+This mod sniffs on the SPI bus of the front panel and draws the display data
+on a modern OLED display. It is a direct replacement for the hard to source
+original VFD displays.

+
+InteractiveHtmlBom (ibom for short) is a BOM tool for various electronics CAD packages designed
+to make manual assembly easier. It also serves as an excellent troubleshooting and documentation aid.
+
+Initially written as KiCad plugin it currently also supports Eagle, Fusion360,
+Allegro PCB Designer and EasyEDA.
+
+This tool generates a convenient Bill of Materials (BOM) listing with the ability to visually
+correlate and easily search for components and their placements on the PCB. It is particularly
+useful when hand-soldering a prototype, as it allows users to quickly find locations of
+components groups on the board. It is also possible to reverse lookup the component group
+by clicking on a footprint on the board drawing.
+
+There is an option to include tracks/zones data as well as netlist information allowing dynamic
+highlight of nets on the board. This feature is particularly useful for troubleshooting the prototype.
+
+Generated html page is fully self contained, doesn't need internet connection to work and can
+be packaged with documentation of your project or hosted anywhere on the web.

+    Replacement DC/AC Amps and AC TRMS Volts option for Keithley
+    Instruments 195A Digital Multimeter.
+  </p>
+---
+
+Keithley Instruments 195A Digital Multimeter is a 5½ digit resolution 200 000
+count instrument that was manufactured in the 80's, possibly early 90's. It was
+available in two configurations: base model that only had DC Volts and Ohms
+measurements and model with 1950 option, which added DC/AC Amps and AC TRMS
+Volts measurements.
+
+Keithley DMM line has long replaced 195/196/199 series with newer models but
+these still show up on Ebay and other outlets and they offer great performance
+for reasonable prices. Unfortunately most of the 195A models available online
+are the ones without 1950 Option.
+
+This project aims to recreate the 1950 Option PCB and circuitry using modern
+components.
+
+In the process some upgrades and some compromises were made. For example this
+version of 1950 option board is based on AD8436 TRMS chip that along with newer
+opamps provides higher bandwidth and better overall specs than much older AD536
+of the original. On the other hand cheaper shunt resistors are used (because
+of their availability) with worse drift and tempco characteristics.
+
+{{% alert warning %}}
+**High voltage** operation using the new board is **NOT** recommended or
+tested.

+KiCad plugin to resize, scale and mirror graphics, tracks, zones, footprints
+and other items in the PCB editor.
+
+Inspired by free transform tool in graphics editors.
+
+<!--more-->
+
+Important notes:
+
+* Mirror does not change layers, it transforms in place
+* When a singular footprint is selected it's items are scaled so the footprint itself will become larger/smaller
+* When more than one item is selected footprints are not changed or rescaled, only repositioned/rotated
+* Pads are not rescaled, only repositioned/rotated
+* Rotation center is geometrical center of combined bounding box of all selected items
+
+Recommended way to get this plugin is to install it from KiCad's plugin manager.
