Projects by N5BIA website is taking a new direction. I am leaving prior project documentation in place for reference, as well as continuing to offer existing stock for sale. I have a couple of the IsoCat assembled and tested, ready for shipment. Send me an email and I’ll get back with available stock and prices.
The new direction I am taking is to place the project description and documentation, parts lists, and schematics here on the website. I will attempt to provide links to a source for pc boards to enable individual or group builds. In most cases, you will be able to order one or more of the boards through OshPark. Where possible, the parts lists will list the manufacturers part number as well as DigiKey and Mouser part numbers.
I am taking this direction because I cannot afford to tie up the resources necessary to purchase and stock the parts to be able to price the products competitively, especially in light of current market conditions. There is no way I can compete with the mass produced options from overseas, particularity China. This is especially true when all some small operator can 'appropriate' a design with no investment other than a bit of web surfing.
I still enjoy the engineering challenges, and plan to continue designing and building as a means of giving back to the ham community, I am retired from the workforce as of 2011, living comfortably, and working on things that are of interest to me. I hope you find something here that is useful as you grow and learn radio and electronics.
New (Old) Products

A few IsoCat kits are still available, at a reduced price of $60 plus shipping. I also have a few completed units that I built for a deal that fell through. These are new, tested, and ready for plug-n-play. All cables are provided, so you could be on the air very quickly. These are $80 plus shipping. Documentation on other Projects offerings will remain available to the community at no cost.
The Projects website is adding new projects, in an altered format. Since retiring a few years back, we have been spending more time traveling as well as addressing some medical issues. What this means for Projects by N5BIA is that there has not been as much capital to build and stock plug-and-play accessories or kits. My interest is still there, though, and I continue to design and build, mostly for my own entertainment and education.
Projects on the bench as of May 2020 include the following:
- IsoCommander - USB serial control interface for control and programming
- VLF receiver - based on the NASA VLF3 VLF design, this is a repackaging effort and addition of features
- IEC444 Test Adapter - enables rapid and correct testing and characterizing of components using a VNA
- WWV TRF - my take on a modern TRF receiver for use as a frequency standard
- Camera Multi-Trigger - infra-red, sound, and light trigger for DSLR cameras
I plan to release these projects as a documentation set and printed circuit boards to enable interested individuals to build one for themselves. I don't plan to produce them, either as a kit or as a finished device. As stated above, time and capital are the chief limits on those activities. Most of the board designs will be available for individual ordering on OSH Park. For those not familiar with their services, they are an inexpensive source of PC boards, primarily for home brewers and limited production runs. While there are less expensive options, you may not have as much control of the finished product at the lower price point.
Blatant Commercial Alert
These projects are offered without cost - copy the documentation, order the boards from OSH Park, and the parts from your favorite vendor or salvage from your junk box. If your do decide to take one of the projects commercial, a small contribution would be appreciated but is not required. Hint: it would help with the development costs for the next project...
I am not affiliated with, nor do I receive and compensation of any kind from OSH Park or from any component vendors mentioned on this site. These resources are passed along to you to assist you in developing these devices for your own use, nothing more.
