The Ultra-Breadboard

W3ITO s article "PRINTED CIRCUITS-ALMOST" in the March 1965 issue of 73

prodded me imti> disclosing to the waiting world an intermediate step between the circuit drawn on paper and the finished product as shown in the W3ITO article.

Usually there is a lot of experimental work It) he done before the project is finished. The circuit as drawn on paper just doesn't perform as planned and the finished product is found to be full of unused holes and odd locations for some of the parts.

The Ultra* Bread board was born to fill the need of a cheap met)tod of trying nut new ideas and getting final layouts without destroying the usefulness of the parts used, inch Masonite Prest Wood and number 14 bare copper wire are the only materials needed and both are readih available and cheap. Your regular socket hole punches and other tools normally found around the shack are all you will need.

The first step is to draw the O/HGi T/1 you are going to use in the project, rheu, using OUTLINES OF THE PARTS lay them out on a piece of paper, using dots to indicate tie-points. Transfer the dots to a piece oi Pi est-Wood and drill with a Vm inch drill, Insert short pieces of the #14 wire through the holes. II a small flat is pressed into the wire where it will he imbedded in the P rest-Wood, the wire will be held securely.

Solder the various parts to the tie points and try the thing. If it doesn't work to suit, simply change parts, rearrange things till you get things perking and then go to the lavout in W3ITO"s article.

It isn't necessar\ to cut the leads to resistors

■m and condensers unless you are working on I MF or VI IF equipment, and the parts can be recovered undamaged to use on the next project.

A small loop on the end of one of the wires permits several parts to be soldered to the same tie point. Another advantage is that since the wires project on both sides of the board, only those parts which are to be experimented with are soldered to the top projections, other wiring is done on the bottom out of the way.
