OzarkCon QRP Conference

Kit Building Workshop

Friday Evening - , 2024
    
The Midwest Homebrewers QRP Club coordinates and supervises the OzarkCon Friday Night Build Session.  Never built a kit or have questions about building ham projects?  Here's your opportunity to learn from the experts.

This year's build session kit is the

Humanalight, an LED flashlight for weak AA batteries.


This year we digress from building the usual Four State kit, and instead build a commercially available kit. Thus saves a tremendous amount of effort and angst for all of us involved in the buid session. We are working hard to bring new kits our product line, as well as another great OzarkCon conference, and time is at a premium this year.

The Humanalight is sold by the charitable organization Ears To Our World as a means of providing radios and flashlights to those in need of communication and light. Thomas Witherspoon, K4SWL, is the founder and excecutive director. Here is their mission statement, copied from their website. "At ETOW, we believe access to information is access to education. We provide innovative, simple and appropriate technologies to schools and communities in remote, rural and impoverished regions of our world."

This little flashlight makes use of the most commonly available battery in the world, the ubiquitous AA. Equally common are "dead" AA batteries. The Humanalight is an adaptation of the Joule Thief circuit with a pcb designed by our own David Cripe, NMØS. Here is another excerpt from the ETOW web page recognizing Dave's efforts.

"Ears To Our World, and those we serve, are very much in debt to our volunteer engineers who made this possible. Many thanks to Gregorgy Majewski for developing and designing the original HumanaLight circuit--he put many hours into testing this amazingly efficient circuit and bringing it to fruition. We also thank David Cripe (NM0S) for designing the HumanaLight circuit board and kit--David made this kit affordable and functional."

This build session will be the perfect opportunity for a family activity, fathers, daughters, sons, granddaughters, grandsons, husbands and wives can all enjoy building this nifty little project.

The build session is limited to 40 participants.  So register early to assure yourself of a kit and a place at the workbench.
The price is $13. Which is good only during pre-registration, and availability is limited to one kit per person.  You must build the kit during the build session, no buying the kit and taking it home at this price. The instructors for the evening workshop will be Dar Piatt W9HZC and Darrel Swenson KØAWB.  Dar and Darrel will guide you through the building process, starting with the "bag of parts" to the finished project.  First time builders welcome!

A large room is reserved so that seating will not be a problem.  Each session is limited to 20 persons (40 total)so that the instructors can provide plenty of 1 on 1 help.   They may however specify one large group rather than 2 smaller ones and stagger the starts by 15 minutes, depending on the project and the number of attendees.  Please check with them at the conference before the banquet.


Pre-register now and save
We are prepared for a large group this year, and we hope to see you in the Build Session.
For the workshop, you will need to bring your own hand tools for the session:
  • Soldering iron with a stand. A small tip on the iron is suggested. This could be a simple 25 watt iron with a bent coat hanger stand.
  • Damp sponge to clean the soldering iron tip
  • Rosin core solder - Kester "44" or similar. Note that we will have some spare solder available.
  • Small wire cutters
  • Needle nose pliers
  • Magnifier and/or light
  • Cookie sheet with upturned lip to catch stray parts, to reduce static discharge damage to components and to protect the table surface
