“Lab” Upgrades

For the longest time my home electronics projects have been done on a 60″ x 30″ folding table in one of our spare bedrooms.  My growing collection of project boxes, spare parts, and equipment finally started to put stress on my furniture – particularly my table.

The old lab table.
The old bowing table in its “clean” state.

I spent embarrassingly too long fretting over whether to buy a desk or build it.  If I bought something, what should I get?  Do I need an “electronics” workbench?  If I build it, what should I build it out of?  I probably spent five months going back and forth – all the while piling more junk on my table.

An amateur’s look at the Rigol DS1052E

My Rigol scope showed up a couple weeks ago and I have had some time to play with it. I’m no expert on test equipment but I’ve been very happy with the DS1052E so far. In particular there have been several nice surprises along the way.

Rigol DS1052e

About a year ago I had to make a tough budgeting decision – something that many fellow hobbyists have to do.  Which would it be – an oscilloscope or a logic analyzer? At the time I was doing alot of FPGA and planning to do microcontroller stuff so I bought a LogicPort from Intronix.  While a great purchase, I’ve found myself looking at analog signals or higher voltages than I expected.

I began watching Craigslist for used oscilloscopes, hoping to pick up a cheap 25Mhz scope.  Meanwhile, I came across David Jones’ eevblog and his review of the Rigol 1052e. In some sort of sign, the Rigol DS1052e’s went on sale this past week for $399 (interestingly only $10 more than I paid for my LogicPort).  Now, I did find a few 50Mhz 2-channel scopes (HP, Tektronix, Hitachi) locally for between $250 and $350 but for a little more I get a new DSO.  Yum.

I haven’t received the scope yet.  I’ll post some info when I get it.  I should also do a review of the Intronix LogicPort – a nice piece of kit.

What’s more is that in the process I discovered eevblog which is outstanding.  I must have spent three hours watching past episodes the other night until 2:00 in the morning.  Great stuff.
