[VicPiMakers Projects] A possible way to overcome SOT23 sizes

[George Bowden]

Hi all
Not quite ready to make pcb that accommodate SOT23 devices, I made these
breakout boards
First I spread a thin layer of epoxy on a thin strip of aluminum (cut from
roof flashing).
Then I dip a finger in solder paste to pick up the SOT23 voltage regulators
legs up, and press them lightly into the epoxy.

Then i cut into the aluminum towards the ICs just enough to jam 30 gauge
wire to hold in place while I solder the wires to the IC legs.

To me it is frustrating that i cannot find fixed 3.3v voltage regulators in
larger size packages with dropout voltages less than .4 volts (3.7v-3.3v =
0.4v)
