When I was shopping for some goodies at All Electronics I came across a circuit card they were selling for $1. Description indicated that the board included two voltage regulators, a crystal and assorted parts. I like to scrounge and look up the parts used in consumer electronics so I purchased one of these […]

In a previous article we introduced the first uCHobby designed kit. The SBBPWR1 is a handy power supply module which plugs directly into a solderless breadboard. The previous article detailed the the overall design process for this kit. The SBBPWR1 has been received well and we got several good suggestions for improvements.
This article describes […]

Six prototyping boards from Wright Hobbies, a new uCHobby sponsor. This article is a brief review of the new boards. A second comment contest where you can win a set of these boards is also announced.
We announced the Wright Hobbies giveaway sponsorship in this previous article along with a comment contest. There have been a […]

My son is about to graduate as an Electronics Engineer and is doing a project involving DSP and RF (radio frequency). He needed a good source for an LO (local oscillator) for his radio and ended up purchasing an interesting kit at AmQRP. This kit uses an Analog Devices AD9850 DDS chip which you have […]

I just got a pile of goodies from Wright Hobbies. I plan on using this stuff in upcoming projects and would welcome any suggestions.  Eddy Wright contacted me about getting a reciprocal link on uCHobby so I checked out his site. Wright Hobbies focuses on robotics and offers a nice starter kit for microcontroller […]

uCHobby’s first electronics kit is a handy breadboard power supply. The power supply design is simple but just what I needed for my electronics projects. I have seen several similar power supply boards but none had all the features I wanted. This design was also a good first project to help me learn about […]

How-to sort a 1 pound grab-bag of small electronic components. I sort through one of the $1 grab-bags I purchased at the Austin Summer fest 2007 HAM meet up. The reason these grab-bags are cheap is that you have to do a lot of work to make the collection of parts useful. I explain my […]

We attended the Austin Summerfest ham meet up. I took along my limited digital camera to capture some shots. The quality is so-so but I hope you get the general idea. Ham fest events are great for the electronic hobbyist. The Ham’s bring large collections of components and test equipment to sell or swap. You […]

How to use low amperage microcontroller signals to control high current devices. Eric explains how to use transistors to get from the logic of a microcontroller to the power needs of a motor.
This article was submitted by Eric Wolf as part of the “Hobby parts for articles ” program. Eric receives a Modern Device Company […]

I have scrounged up several LCD displays and wanted to use one with the Arduino. At the very least I wanted to test the displays. For future projects with the Arduino having a LCD display could be very handy so for this reason it is a good first project as well.

Unfortunately interfacing an LCD uses […]
