![]() ![]() Supporting it are a few transistors and a handful of passives. The circuitry was open for all the world to see on the bottom of the tester. 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. My particular unit arrived with the LCD flapping in the breeze, hanging on by its flex cable. This thing is built cheap – as cheap as the factories can make it. I’m going to get the obvious out of the way. Two days later I had a “SainSmart Mega328 Transistor Tester Diode Triode Capacitance ESR Meter MOS/PNP/NPN L/C/R” in my hands. Curiosity got the better of me and my mouse found its way to the “Buy it now with one click” button. I’ve been seeing those testers around quite a bit lately. Their customer database paid off when it recommended a $22 transistor / component tester. ![]() Every time I log in, I’m presented with a list of new Blinky LEDs, Raspberry Pi accessories, Arduino shields, and the like. Amazon has been getting creepier and creepier lately with their recommendations.
