Design,



No matter what you do yo need to have a plan. For example this boat we wanted with the fewest number of seams.

Analog computer cluster

Building a six plus node analog computer cluster. An analog computer is a device that measures some value.


Place the rulers end to end to do clustering or


Analog adding calculator. Over simplified, but


Super calculator

You can almost build your own mainframe computer using COTS (commodity off the shelf) hardware and then you can have one heck of a calculator for your desk.

Harvesting a 5 1/4 drive.


You could use most any micro-controller to do the same thing, but you might need extra electronics.

Let it die or Salvage it.

New printers are cheaper than replacing ink cartridges. Chunk or salvage?






You will still need to get a new printer.

Safe computer.


Your computer is completely safe now. We just have not figured ot how to use it this way yet.

The switch.

Generally we use a switch to turn something off or on such as a light.




But how is that accomplished?  You need a power switch, power source, and a power drainer like a light bulb.  Normally the switch is open so that no current can reach a light bulb as a full circuit

So if we can close the circuit so cuurent can reach a light bulb as a full circuit, the light will turn on.

Actually we can do sort of the same things with an electronic switch or transistor, If there is not power to the junction of the transistor then the light or led's will not light up.The advantage is that no traditional switch has to be touched.



Then if we add power to the base of the transistor or led's they light up.





So we can tell a computer or microcontroller to turn on the power to light am led.

Latest botnet issues.


Any system can have malware, but the latest botnet mess was caused by systems not being secured well and not because of a virus. In fact the reports going on to say that the existing system files were not altered. Only additional programs being brought onto the system were the real issue causing the ddos problems.
