BSide ACM03 Plus Clamp Meter Review and Teardown

I recently purchased a BSide ACM03 Plus clamp meter so that I could do some high current measurements for my tab welder project. This meter can be bought on eBay for around $25, which makes it one of the cheapest Hall effect clamp meters on the market that is capable of measuring both AC and DC current.

Quick Review of the ennoLogic eM860T True RMS Multimeter

I picked up an autoranging True RMS multimeter from ennoLogic a couple of weeks ago. Before this purchase, I actually had never heard of ennoLogic. But the design and spec of the meter looked quite good and the selling price was not bad for a 6000 count meter at all. So I bought one to try out.

Exploring the Battery Option of the EDC/Krohn-Hite MV216A DC Voltage Standard

In my previous blog post, I did a teardown of the EDC/Krohn-Hite MV216A DC voltage standard and measured the temperature coefficient of its reference Zener diode. And as I promised, this time I will explore its internal and external battery options. Continue reading ‘Exploring the Battery Option of the EDC/Krohn-Hite MV216A DC Voltage Standard’ »

HP 5350B Microwave Counter Teardown

Here is a teardown you do not see very often. I recently bought an HP 5350B 20 GHz microwave counter off eBay. HP 5350B uses harmonic heterodyne down-conversion technique to convert the microwave frequency into the range of its internal low frequency counter. It can measure frequencies from 10 Hz all the way up to 20 GHz via two separate inputs. Continue reading ‘HP 5350B Microwave Counter Teardown’ »

BK 4011 Function Generator Teardown

I got a used BK Precision 4011 5MHz function generator recently. The 4011 model is rather old and this particular unit was manufactured back in 1996. But BK precision still makes a similar model (4011A) which is identical to the older 4011 spec-wise except for the inclusion of an additional INV button for inverting the output waveform. Continue reading ‘BK 4011 Function Generator Teardown’ »

Topward 6603A Linear Power Supply Teardown

I bought a used Topward 6603A lab power supply from eBay a couple of weeks ago and thought I would do a quick review and teardown and perform some basic measurements to see how well it was built. Continue reading ‘Topward 6603A Linear Power Supply Teardown’ »

Prototyping With Schmartboard Arduino Shield Board

Neal at Schmartboard sent me a 0.65mm pitch Arduino prototyping shield kit a few weeks ago. I had meant to do a review right away, but then thought it would probably be even better if I built a real project with this board to see how well it worked first before sharing my experience with you.

MaxiScan MS300 ODB II Reader Teardown

I bought an ODB II code reader to diagnose a check engine light problem of my car. The reader I got was an Autel MaxiScan MS300. This particular model is very popular as it is rather inexpensive, coming in at just around $20. Out of curiosity, I decided to open it up and take a look of what is inside. Continue reading ‘MaxiScan MS300 ODB II Reader Teardown’ »

Inoperative By Design

I recently bought two cheap webcams on Amazon and was planning to do some experiments with a dual webcam configuration. These cameras got pretty decent reviews and cost only a few dollars a piece, so I thought what could go wrong with these anyway? Continue reading ‘Inoperative By Design’ »

SchmartBoard — First Impressions

For a lot of electronics enthusiasts and DIYers, hand-soldering SMT components can be a great challenge. And given the trend of component miniaturization, a lot of ICs no longer come with DIP packaging. Soldering such small components by hand without proper equipment (e.g. SMD hot air rework station) can be extremely difficult for beginners. The folks at SchmartBoard were kind enough to send me a few of their SMT prototyping boards to play with. So I decided to try them out to see how their proto-boards stack up with some of the alternatives on the market. Continue reading ‘SchmartBoard — First Impressions’ »

X-TRONIC 4040 Hot Air Rework/Soldering Station – II

Last time I did a pretty thorough review of the X-TRONIC 4040 hot air rework/soldering station and shared my own experience with it. Overall, it is a very good entry level rework station. I have been using it intensely for the last week or so and it is holding up extremely well. Now let us take look at what is inside.

X-TRONIC 4040 Hot Air Rework/Soldering Station – I

I have used quite a few professional SMD rework stations before, but those professional grade ones tend to be quite pricey. So when I decided to get a hot air rework station for my own personal use, I settled on the cheaply priced X-TRONIC 4040 hot air rework/soldering station combo. In this blog post, I will do a detailed review of this rework station and walk you through some of my observations. In the next time I will do a review of its internal construction.

My Take On BK 2709B Multimeter

I recently bought a new digital multimeter (BK 2709B) and after a couple of months’ use, I am quite satisfied with its features and performance. So I thought I would do a quick review and share my experience here. Continue reading ‘My Take On BK 2709B Multimeter’ »

Arduino Robotics – A Short Review

Apress was kind enough to send me a copy of their recently released book “Arduino Robotics” a few weeks ago (ISBN13: 978-1-4302-3183-7, 628 Pages. Publication Date: July 18, 2011). So I thought I would read through and do a quick review on it. Continue reading ‘Arduino Robotics – A Short Review’ »

My New DS1052E Oscilloscope

I used to own an all-transistor, single channel 10 MHz analog oscilloscope. While it was not adequate by nowadays standard, it served me quite well for many years. The scope was later sold and I had been thinking about getting a new oscilloscope for quite a while. This time around though, I wanted to get a digital storage oscilloscope (DSO) since in many cases, it is a lot more convenient to use. After reading about some rave reviews on Dave Jone’s EEVBlog about this Rigol DS1052E scope, it became apparent that this would be the ideal scope for my workshop. So without much hesitation, I ordered one. Continue reading ‘My New DS1052E Oscilloscope’ »
