All flash Field Replaceable

Make all Flash Memory in Home Appliance, Gadgets and computers - Easily Replaceable and Field Replaceable. If possible replaceable by layman like batteries.

Many people are having problems and high costs of service, as equipment and devices made over the last few years have flash that is hard to replace and source.

The only flash that can be SMT and Soldered could be the ones loaded with "Static Software or Firmware". That means that area of memory that is subjected to very less write cycles. Even Firmware that is frequently updated should be on an replaceable module.

Make All flash Field Replaceable

I first experienced flash usage in a 8051 based Fuel Dispensing Unit we were developing in the late 80s. It was a SEEQ chip with 10K Full Erase/Write Cycles. it was a pin-2-pin replacement for 2732 UVPROM (kilo bytes). It later needed a piggyback timer.

Flash has developed immensely since, It lasts much longer and goes to Giga Bytes Storage. Giga Byte was BigData in the 90s.

Also Frequent software updates must be written as an overlay over the "Static Software".An External SDCARD as a database/code source for the updates.

Keep all frequently up-gradable parts of a firmware in a easily replaceable device called "DynamicWare" which includes the Interface/Internet areas and all that is susceptible, vulnerable, UI and young-and-growing sections.

So we have StaticWare Flash for OS, DynaWare Flash for Updates/Fixes/Apps. and External Flash for media/apps. The StaticWare alone can be SMT Hard Soldered into PCB, this should have enough smartness to upgrade device on Wi-FI with barebone GUI.

Gizmos and Gadgets that consume more batteries can be supplied with easily pluggable battery and spare battery with charger. This way the battery can be quick replaced when drained, rather than charging the device. This reduces system downtime.

Usability of Front Panel Controls

I once worked in Tek for a very short period. I got to experience the 2235 and 2465 analog scopes and their controls. The 2465 was a 400 MHz Digitally Controlled Analog Scope.

I also used the Plugin System Scopes and Calibration systems; these were Tek Culture and Tech contribution to the Instrumentation world, it probably evolved into VXI-PXI as uC systems took over.

I also had a chance to look at DSO/Logic Analyzers and the just developed TDS Series. The older tek analog scopes made me understand about usability and panel layouts. Many controls are inevitable in a Analog Scope with Electromechanical Interface.

In a Digital World that can be largely changed using the Monitor and Trackballs. The older BlackBerry phones are also good study for usability before Touch Screens came.
