MySQL Workbench v5.2.34 – 2nd meeting

Early experiences with the MySQL Workbench IDE version 5.2.34, revision 7780 – part 2.

I refined the data model a little.

Export of ER diagram V2 from Story Schema

I edited in a minimal set of data for test purposes, this included entry of two characters from Book, and a (limited) selection of page references taken [...]

MySQL Workbench v5.2.34 – First Contact

Early experiences with the MySQL Workbench IDE version 5.2.34, revision 7780

Export of ER diagram from Story Schema

First impressions:

It’s easy to install.

The download and install on my XP machine went without a hitch, including the necessary pre-requisites – in this case a Visual C++ re-distributable run-time and .NET component.

It’s pretty.

Neatly laid out and with exceptional [...]

Pimping an Op-Amp for wide voltage swings

A wide-voltage swing op-amp for less than £1.00?

As promised in an earlier post, I describe here my experience in turning a common-or-garden TL081 PDIP op-amp into a wide-voltage swinging monster, with a minimal sprinkling of SMD and a small circuit board made from scraps.

Prototype 72 volt op-amp

I wanted to augment my current heavy-duty power-supply [...]

Simple Dual-voltage Tracking Power Supply for 3 to 15 volts

Updated 16th May 2012

Completed prototype

In a previous post: Versatile Dual Power Supply Printed Circuit Board I described a dual power supply design that I hoped would fulfil 90% of my needs. To this end, it was very successful, and several have been built and installed in various pieces of equipment. These have been mostly [...]

Single-transistor pre-amp for very-low-impedance Guitar Pickups

A number of my posts (see menu at foot of post) have covered the construction and amplification of home-made guitar pickups fabricated from hard-disk magnets. The amplification so far discussed has generally included the use of op-amps – particularly the Texas TL071/072/074 series. With this post I discuss an alternative – a single transistor amplifier, [...]

SMD Resistor kit storage – a headache solved with a 4-a-day Pill Planner for 99 pence?

The last few kits of SMD resistors I’ve bought off eBay have arrived as short cuttings from bandoliers, with each resistor nestling safely in it’s tiny little cardboard nest. Although care is needed when extracting a resistor for use, these are easy to store in cheap multi-compartment drawers.
However, the last lot I ordered from Hong [...]

My Top 3 – Sex, Guitars & The Microchip PIC Processor!

No, not a narcotic in sight, but because communicating seems to be the new ‘drug’ of the masses, the micro-controller is a worthy substitute?
Close runners-up are debt and synthesizers – strange bedfellows indeed.

I don’t draw any conclusion from this months statistics, I’m pleased that so many find these pages of interest, and hopefully, ultimately useful.

Pride [...]
