Today's product review is a DIY Transistor Tester Kit from GearBest.com. This is a simple little kit that will be pretty rewarding for anyone who uses it. For the noobie, it is a good way to work on your soldering skills, all of the components are through hole so even somebody brand new to soldering would be able to assemble.
For someone with experience, maybe you just want a new transistor tester. And what's better than assembling your own?? I really enjoy these types of kits, they are sort of a relaxation thing for me. I can have the satisfaction of putting something together that does something pretty cool without having to do any design work or engineering. Once I start to assemble this I will be documenting it on my Instructables page as well as showing how to use it.
Here are some of the specs from the GearBest webpage:
● One key for measurement operation, auto power off delay. Shutdown current is only 20nA, support for battery operation
● Capacitance measurement range from 25pf to 100mF. 0.09uF capacitance can be detected above the equivalent series resistance (ESR), resolution is 0.01 ohms● Inductance measurement range from 0.01MH to 20H, otherwise it will be displayed as resistance if the inductor DC resistance is higher than 2100, that will be displayed as the European resistance.● The square wave signal generator can produce optional built-in stall square wave signal within the range of 1HZ - 2MHZ ● PWM pulse signal generator produce the pulse width modulated signal of 1 - 99 percent● The frequency meter function can test 1HZ - 25KHZ or higher frequency signal (in this case a slight decrease in accuracy)
Hello Mr.Jordan,
ReplyDeletewith regard to your instructable at
http://www.instructables.com/id/Arduino-ControlledVoice-TV-Remote/?ALLSTEPS
I struggling with your "remote" code using arduino 1.6.5
WProgram.h does not exit anymore, I renamed it to Ardnino.h still i get below errors.
I can record with your "IR_reader.ino" without any problem. My PC is connected to a SAMSUNG TV so i need when my PC auto wakeup, to press "TV power on" "VolUP" etc.
With your tallent i am sure you can fix it in seconds! so you can mail me at westpromise@live.com
Thank you for the inspirational instructable
Best Regards
West
