Hiland M644 Multifunctional Transistor Tester LCR Resistance Inductance Diode Capacitance ESR Frequency Meter PWM Signal Generator (WHL #50)

Another component for one of the upcoming projects – a refreshed transistor tester.

I’ve been using these for ages now, I actually built two of them before they got popular (what a hipster thing to say?) and every Chinese seller decided to roll his own. The original thread on mikrocontroller.net dates back to early 2012 and the SVN repository even contains a few fixes of mine to the manual, as I was proofreading this thing at the time.

Times have changed, and the ready made versions are so cheap nowadays that homebrew really doesn’t make any sense any more. […]

Failed Philips 46PFL8008S/12 display repair (#P15)

And now for the thing that didn’t make it #100 ;)

A while back, I was donated my second “defective” TV, a 46″ Philips 46PFL8008S/12 with the large ambilight (left/2x top/right with 9 LEDs each). Unlike my first donor which pretty much suffered a direct lightning strike (as described in rant #R2), this one turned on just fine. What’s wrong with it, why would you give away a former 1500€+ device?

(bonus brownie points if you can name the show currently displayed here!)

Well, story is this poor fella cracked a glass table. […]
