show me your home lab!
“What’s your choice for a single best aid to an interesting and productive circuit design career? A PhD? An IQ of 250? A CAD workstation? Getting a paper into the Solid State Circuit Conference? Befriending the boss? I suppose all of these are of some value, but none even comes close to something else. In fact, their combined benefit isn’t even worth a fraction of something else. This something else even has potential economic rewards. What is this wondrous thing that outshines all the other candidates? It is, simply, a laboratory in your home. The enormous productivity advantage provided by a home lab is unmatched by anything I am familiar with. As for economic benefits, no stock tip, no real estate deal, no raise, no nothing can match the long-term investment yield a home lab can produce. The laboratory is, after all, an investment in yourself. It is an almost unfair advantage.
The magic of a home lab is that it effectively creates time. Over the last 20 years I estimate that about 90% of my work output has occurred in a home lab. The ability to grab a few hours here and there combined with occasional marathon 5-20 hours sessions produces a huge accumulated time benefit. Perhaps more importantly, the time generated is highly leveraged. An hour in the lab at home is worth a day at work.
A lot of work time is spent on unplanned and parasitic activities. Phone calls, interruptions, meetings, and just plain gossiping eat up obscene amounts of time. While these events may ultimately contribute towards good circuits, they do so in a very oblique way. Worse yet, they rob psychological momentum, breaking up design time into chunks instead of allowing continuous periods of concentration. When I’m at work I do my job. When I’m at home in the lab is where the boss and stockholders get what they paid for. It sounds absurd, but I have sat in meetings praying for 6 o’clock to come so I can go home and get to work. The uninterrupted time in a home lab permits persistence, one of the most powerful tools a designer has.
I favor long, uninterrupted lab sessions of at least 5 to 10 hours, but family time won’t always allow for this. However, I can almost always get in two to four hours per day. Few things can match the convenience and efficiency of getting an idea while washing the dishes or putting my son to sleep and being able to breadboard it now. The easy and instant availability of lab time makes even small amounts of time practical. Because no one else uses your lab, everything is undisturbed and just as you left it after the last session. Nothing is missing or broken, and all test equipment is familiar. You can get right to work.”
