Review Transistor Tester Hackaday. Amazon has been getting creepier and creepier lately with their recommendations. Every time I log in, Im presented with a list of new Blinky LEDs, Raspberry Pi accessories, Arduino shields, and the like. Its as if they know me. Their customer database paid off when it recommended a 2. Ive been seeing those testers around quite a bit lately. Curiosity got the better of me and my mouse found its way to the Buy it now with one click button. Two days later I had a Sain. Smart Mega. 32. 8 Transistor Tester Diode Triode Capacitance ESR Meter MOSPNPNPN LCR in my hands. Im going to get the obvious out of the way. This thing is built cheap as cheap as the factories can make it. My particular unit arrived with the LCD flapping in the breeze, hanging on by its flex cable. Fitting the LCD back into the acrylic backlight frame revealed a slightly worrisome twist in that same flex. Thankfully nothing was actually damaged, though I do want to give the flex cable some protection in the future. More on that later. When asked about the privacy context collapse involved in revealing your Echo ownership to anyone with your phone number, an Amazon spokesperson emphasized that. Last month, internet service provider Cox began charging residential customers in Arizona, Louisiana, Nevada, and Oklahoma an extra 10 for every 50 gigabytes of data.

Do you love that sensation of suddenly being hurled forward when you have to abruptly slam on the brakes If youre in a selfdriving car, the effects apparently. The circuitry was open for all the world to see on the bottom of the tester. The heart of the unit is an ATmega. Supporting it are a few transistors and a handful of passives. I didnt have huge expectations for the tester, but I hoped it would at least power up. Hooking up a 9 volt battery and pressing the magic button brought the tester to life.

By Efan Hao. Qixin, then it informed me that I had No, unknown, or damaged part. I had a few resistors lying around the bench doesnt everyone so I put one in. The tester read it as 9. Sure enough, it was a 1. K 5 resistor. Capacitors ceramic disc, electrolytic, and surface mount all worked as well. The tester even provided ESR values. The real test would be a transistor. I pulled an old 2. N2. 22. 2 in a TO 1. The damn thing worked it showed the schematic symbol for an NPN transistor with Collector, Base, and Emitter connected to Pins 1,2,and 3 respectively.

Flipping the pins around and re testing worked as well. The tester showed h. Fe as 2. 16, and forward voltage as 6. Psp Serial Number Checker' title='Psp Serial Number Checker' />V, both reasonable numbers for a 2. N2. 22. 2. The tester worked surprisingly well it was able to correctly identify BJTs, FETs, even esoteric parts. The only thing it balked on was a linear voltage regulator, which showed up as two diodes. Regulators are a bit more than a simple device though, so I cant blame the tester there.

While I dont have a calibrated lab to check against, the numbers lined up with my Fluke meter. So what exactly is driving this little tester There are about 2. China. 9. 1make is a seller on taobao. Chinas ebay. 9. LCDs. Some digging turned up the history on this device. It turns out the transistor tester is an open source hardware project translated originally created by Markus Frejek, and built upon by Karl Heinz Kubbeler and a number of others. The Subversion repository for the project shows it is quite active, with the most recent check in only a few hours ago. The project is also well documented. The English PDF is 1. The document even explains some of the shortcomings of the Chinese versions of the tester, including using a zener diode where the original schematic calls for a precision 2.

The devs also dont officially support the clones which I can understand, considering the quality and changes in design each manufacturer is baking in to their own version. There is a huge thread on the EEVblog forum covering these testers. Some can be modified to be closer to the official version. In fact, with an ISP tool the intrepid hacker can update the firmware to the current rev from Karl Heinzs repository. So the final verdict on this tester is that it is a thumbs up with a small caveat. These testers are built down to a cost and that cost is as close to zero as possible. Theyre great for sorting parts, but theyre no substitute for a higher quality measuring device. Id also love to see a version that supports the original developers.
