In this post, I will review a nice multimeter by TENMA, model 72-7735. This is an advanced autoranging multimeter(!) that lets you measure the following electrical properties: AC voltage 0V to 1000 V DC voltage 0 V to 750 V Resistance 0 Ohm – 40 MOhm Capacitance 0 nf to 100 uF Frequency 0 Hz […]
I posted this as instructable at instructables.com/id/Wind-your-own-coils-quickly/ Ever needed to wind a coil quickly? Coils can be used to make actuators, electromagnets, and even to communicate energy! I use small copper coils in my micro RC airplanes and I wind my own coils quickly with this tip. (See some of the planes I built on my […]
This is a homemade adapter I made for programming SOIC/QFN size microchips. I had trouble connecting the chips any other way so I made my own. This could also be used to do In-Circuit programming without removing the chip from the PCB. If you want an adapter to connect and fit any size microchip, this […]
You can make your own ultra light polarized micro connectors at home! Polarized means the have a male and a female set in one connector, thus preventing from mixing up the polarity. The end result is an ultra light 2 pin connector that you can use for various purposes in your micro electronics/hobby projects. I […]
I was digging up my photo archives and stumbled upon pictures of some RC micro airplane models that I built long time ago as a hobby. I will start posting pictures of my micro airplanes along with details about them, maybe this will inspire you to build some models like this or at least […]
