I've already started working on a few of them. I'll be keeping all these projects in a separate section:

Free PCB Design Service

I haven't designed a PCB in a while, and I really wanted to get back into the game, so I decided to do something crazy.

Yep. Seems like there are quite a few people who are interested in having a PCB designed for free.  We'll see how this turns out.

(From rigolna.com)

I got a shiny new Rigol DS1052E oscilloscope, yay!  An oscilloscope is definitely one of those tools that you just need to have as an electrical engineer.  A lot of the time you won't need it, but when it's 3am before a big project is a due, it's nice to have access to one rather than needing to go to the lab in school to use one.  

I got mine from tequipment.com for $379.05 delivered ($399-5%).  Delivery was ridiculously quick (free ground and got it the next day, but it was from NJ to MA). This is basically the best bang for buck oscilloscope on the market right now.  I had originally wanted to get the $15 more expensive Instek GDS 1062A, which has slightly better specs, but it was backordered for over a month, so I just switch over to the DS1052E.  The DS1052E comes very highly recommended by Dave Jones at theEEVBlog, which definitely played a large part in my decision.

I figured I really should get and oscilloscope because it's a tool that will be useful for a long time.  Plus, it's one of the few pieces of equipment that would be absolutely impossible for me to build on my own, as compared to a function generator, or a power supply or whatnot

New Multimeter

So my old crappy $10 multimeter from Futurlec died on me.  I wanted to get a nice Fluke multimeter but the model 117 I was looking at was about $120.  

Looked around a bit and found this Extech EX330 that had all the functionality I wanted, and it was nearly as good as the Fluke, for about $50 rather than $120.

Like it so far.

Pro Soldering Iron

Bought a high quality Weller WESD51 Soldering Iron/Station from Amazon.com.  I figure I should really invest in a quality soldering iron because it is a tool I will be using for the rest of my life.  I really like the digital temperature display, and it is constantly updated to the actual temperature of the tip, which is nice.  Now I can actually set the temperature to just above the melting point of the solder (~450degF for the solder I have) so that I dont destroy my parts due to heat damage.

We have similar soldering irons in the EET labs and they still work like champs despite being beat up by EET students.

New Camera

posted Feb 2, 2010, 3:30 PM by Bill Bai

I realized that I need a good camera if I want to do any effective documenting of my various projects.  After doing some research, I decided on the Panasonic Lumix DMC-FP8.

I really like the form factor, and it's a pretty good camera for $180.  The CNET review said it was one of the fastest cameras they had tested, and that was a major issue for me with previous cameras.

$180 and free fast shipping.  It should be here in a couple of days.  The 8GB SDHC card I ordered from Newegg will take a few more days to get to me though (still free shipping).
