Fuse based dead bug

@07/17 2015

as a hobbiest for RF, you definetly should know AA7EE, https://aa7ee.wordpress.com/ , known with his incredable beautiful manhattan construction for RF rigs. allow me to cheat some picture from AA7EE.

there is many type of manhattan building method, mainly focus on how to cut your own supporting pole. some supplier give you pre cutting board for this purpose like the MeSQUARES on the QRPMe.

you can choose to make you own pad with Punch.

another popular building method is island, but you need a tools to cut it into the copper clap board, that would be annoying sometime, usually use a diamond mill(for dill hole in the glass or ceramic), but need a powerfull drill for that, and skills, a desktop drill is good choice.

there is a interesting manhatan board created by K3PEG, http://www.4sqrp.com/kits/EMI_AudioAmp/k3pegpix.html, is another type art of circuits:

A New Pad for manhattan build

i struggle to get a pretty looking circuits instead of analog chaos, my circuit always like crap:

recently i found another suitable thing for manhattan style building, the little fuse, 3mmx10mm, i burn it use large amount current flow, after it broken, the resistance is very large to tens Megohm. and the capacitance less than 1pf. seems suitable for , VHF.

use dead fuse, you don't need the drill or the glue to stick the pad, just use iron soldering to the copper clad board. and, the fuse itself could soldring resistor or capacitor, then reduce the size of circuis.

Local supplier suitable for manhattan pad

i do found some supplier make pad suitable for manhattan construction, these pad is a little bit large and thin: 1.00mm FR4. there are double side, one side contain 3 traces, another side is a "M" trace. the 3 traces side suitable for LM386 or similar IC, another side could be used for wires.

and there is also another copper clad strip board, but no cut slot so hard to get one of them.

Important thing to make a neat circuits

the most important thing to build manhattan circuits is, DO NOT TRYING BUILDING A TINY CIRCUITS. layout your board with some room there, it help you debugging, make change.
