Rants: Second Room, New Lab

Back in March, I moved from Kingston NY to Lawrence/Andover MA to work as a design engineer for a power electronics company. Due to the fact I needed to find an apartment within a 3 week time frame, I had no other choice but to rent a two bedroom apartment, even though I will be the only one living in the apartment. So, what did I do with the extra room? I turned it into a lab! Although I still need to get a bench multimeter, hot air soldering iron, etc, I think it’s a good starting point. Anyway, here’s a small tour of my lab.

So right now my inventory is pretty sparse. The cabinet on the bottom I had before I moved to MA and contains spare items.Some of the items include diodes, op amps, atmel and PIC18F  microcontrollers, PIC programmers, and AVR programmers. However, one of my co-workers gave me his old electronics cabinet. This one contained a diverse amount of through-hole discrete parts such as resistors, capacitors, even some inductors. Either way, I will not run out of discrete components anytime soon.

So I obtained another goodie from my co-worker- a power supply (15V/1A). Although I do not use it often since I have a higher wattage power supply (32V/5A),  I’ll find a use for it soon. For the first time in my engineering career, I finally invested in a….meh function generator. I never heard of Victor before obtaining the function generator, but it does a decent job. My chief complaint is the minimum and maximum duty cycles for square waves. This function generator can only be set to have a 20%-80% duty cycle for square waves. As a person who likes to switching things at a fast pace, this continues to annoy me.

One of my electrical engineering colleague told me that a good electrical engineer typically has an analog and digital oscilloscope. I took that advice to heart and obtained an old school analog oscilloscope from – you guess it – my current co-worker. I’m not going to lie, I’m still tying to figure out how to use this scope. I tried looking for the instruction manual online and even asked my co-worker who lend me the oscilloscope, and I still cannot figure out how to use it.

So this is one of the supplies I brought while I was living in Kingston. As embarrassing as it sounds, I lost the caps to the power supply’s output during the move to MA. For now, I have alligator clips attached to the power supply’s output. Although the current capability of the cables is a little less that the maximum current the power supply can deliver, my current projects are not really current demanding, so I can get away with it. Of course, I cannot forget my multimeter from Radioshack, Although I was groomed to love Fluke multimeters, I cannot complain about it as it gets the job done. I will get a bench and Fluke multimeter sometime in the future.

So here’s my current oscilloscope. Originally I wanted to get a small cheap Techtronix oscilloscope but apparently the cheapest Techtronix oscilloscope I could find at the time was $1000. So…I brought a Hantek oscilloscope from Ebay. Although I find the screen to be a little hard on the eyes and the speed isn’t something to brag about,I can save pictures using USB! I cannot tell how many oscilloscopes I used in the past could only save waveforms using a floppy drive. I know it’s petty, but after using oscilloscopes for two years  now, it’s kind of a big deal.

So the last item I got for my lab is my new soldering iron. My previous soldering iron I obtained from Radioshack started to affect my soldering. Instead of getting another cheap crappy soldering iron, I decided to invest in a Hakko 936 soldering iron. Not only did I get a new soldering iron, but I got two chisel tips with them. What’s great about these chisel tips is that the heat is spread out a little more, making through hole soldering a little easier.

So that’s it for my little post for today. Again, I apologize for the delay, but assimilating to life in MA was….more time consuming that I thought. Anyway, thanks for reading this post and if you have any suggestions on any lab equipment I should get, then please comment below! I will see you guys next week and have a wonderful day!
