In this age of SMT, tweezers are indispensible.

Good point -- however I personally use only traditional lead-through-hole components for my hobby projects -- so that's not proved to be an issue thus far :-)

UUtility knife, hacksaw, & small adjustable wrench/vice-grip

An absolute must is a utility knife. I think they may be called box cutters in the US. An Xacto knife is often handy as well.

A small hacksaw is often good at making something fit.

And a small adjustable wrench and/or a small vice grip is also very useful

Of course, many of us have a deep-seated belief that you can never have enough tools.

I frequenly will have two or more of the same type of tool.  I was recently asked if I had a staple gun and when I replied that I had two (a manual and electric), my non technical friend just cracked up laughing. I didn't see the humour.

@Antedeluvian: I agree that all of these are useful -- each project may rely on one or more of them -- out of all of them I guess I find myself using an Xacto knife an the majority of my projects.

You shouls have introduced your friend to the sharp end of the staple gun to show him (or her) the error of his ways :-)

Why a Wrap?

A lot of my projects use development boards that have 25 mil square wire-wrap pins on a 0.1" grid.  I like to insert these into a perf board and then use good-old 20th Century wire-wrap to connect them up.  It's quick, easy to fix errors, and easy to dismantle to re-use the boards in other projects.

Solderless breadboards are also great for quick projects, but don't expect them to stay intact if you have cats :-)

De-soldering tool
GarySXT   3/4/2014 5:28:31 PM
If you solder parts on a circuit board, sooner or later you will have remove one because you installed the wrong part, need to change the value to get the circuit to work, or you make a mistake and let the magic smoke out.  To minimize the chance of damaging the board you need something to help remove the solder.

I prefer the larger spring loaded solder suckers. I never found a small one that works well. Solder braid is another option, but you have to buy more as you finish a roll. It also does not work as well at getting the solder out of plated through holes.

My wife just got a new cat (her last one passed away age 17 a couple of months ago). This new one is a very energetic kitten. I heard a disturbing sound yesterday evening -- when I looked up it was strolling across our breakfast table, upon which was my current Arduinoi project with a rats nest (no pun intended) of wires. I don;t think I need to describe the end result (sad face)

I've used both the braid and the solder sucker -- each works best in different cases. Recently I read about someone who used a "blower" rather than a sucker -- but I don't remember much about it -- do you know anything about this technique?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
