Breadboard Radio – Ham Radio Kits that are easy to build and fun to use!
KM4ACK
Build-a-Pi will allow you to get up and running fast with a Raspberry Pi for ham radio.
Wait what? Last month’s Ham and Eggs attendees received a USB key packed with tools and software for Winlink, JS8Call, and VARAChat. Perfect timing, there is training posted at ARES-SC.org that will take you through Winlink A-Z. More details are below:
NOTE: This is will a late evening event, it is posted to be a 7 pm PST time, making it 10 pm for the east coast.
Midlands Skywarn Newsletter Sign-up
The Columbia SKYWARN Team assists the Columbia National Weather Service with Ground-Truth weather observations during severe or dangerous weather. The Columbia NWS forecast area covers much of South Carolina and is divided into August/CSRA, Midlands, and Eastern Midlands.
The Columbia SKYWARM Team holds NETS and Virtual Training/Meetings weekly and monthly. More Information can be found at the Columbia Amateur Radio Club Calendar

Founded in the 1970s, the information provided by SKYWARN Spotters, coupled with Doppler radar technology, improved satellite, and other data, has enabled the NWS to issue more timely and accurate warnings for tornadoes, severe thunderstorms, and flash floods. SKYWARN Storm Spotters form the nation’s first line of defense against severe weather minutes that can help save lives.
In most years, thunderstorms, tornadoes, and lightning cause hundreds of injuries and deaths and billions in property and crop damage. The National Weather Service (NWS) established SKYWARN with partner organizations to obtain critical weather information. SKYWARN is a volunteer program with 350,000 and 400,000 trained severe weather Spotters. These volunteers help keep their local communities safe by providing timely and accurate reports of severe weather to the National Weather Service. Although SKYWARN Spotters provide essential information for all weather hazards, the focus is reporting on severe local thunderstorms. In an average year, the United States experiences more than 10,000 severe thunderstorms, 5,000 floods, and more than 1,000 tornadoes. (Information courtesy of the Columbia NWS)

A few years ago, I decided to upgrade my PC. In researching, I found a mini fan-less PC that runs on a 12v wall wart. After researching my software wouldn’t have any issues I purchased and installed the software I use.
The only issue I had was that even with my off the shelf UPS system the PC would reboot during bad weather. I investigated and found the wall wart was susceptible to power line transits.I thought about using one of my ham radio power supplies, which I thought was way over kill.
Searching the internet I found that battery operation was preferable. But then again it was much more than I needed. Then on “YouTube” I found them using an oversize AA with a voltage of 3.7v. This is actually called a 18650 cell as the designated size. What was impressive was the different capacities viable on “Amazon”. These cost from $2.25 in multiples and capacities from 2000mah to 9900mah
More research indicated I could build a DIY UPS with no switching time and a fairly large run time. Since the most time I have been without power has been less than 1 hour. So I sat down and worked out a wiring diagram. The schematics program I use is called “Fritzing”. Here is a link to the webpage for the software. https://fritzing.org/
Here is the parts list, cost supplier.
| 12v 18650 UPS BOM | |||||
| QTY | Label | Part Type | Unit | Part Number | Supplier |
| 1 | Case | Enclosure | $18.99 | Blue Metal Enclosure.7 x 4.33 x 3.1 inch | Amazon |
| 1 | 120vac to 12vdc | S-350-60 Power Supply | $12.98 | 12v @ 5amp | Amazon |
| 1 | 5.15V Out | Generic female header – 2 pins | $1.44 | Terminal Binding Post Spring Clip 2-Way | Amazon |

| 3 | Bat1 | 18650 Battery | $5.97 | 3.7v @ 9900ma | Amazon |
| 1 | C1 | Electrolytic Capacitor | $0.35 | 470uf | Amazon |
| 1 | D1 | Rectifier Diode | $0.05 | 1N4007 | Amazon |

| 1 | U1 | Buck converter | $3.24 | Mini-360 Step-up DC-DC | Amazon |
| 1 | VM1 | Voltmeter | $2.16 | 3 digit LED (2 wire) | Amazon |
| Total | $49.27 | ||||
Here are a couple of pictures of the finished unit.
The Future-
Since I also operate a couple of Raspberry Pi’s 24/7, I am refining the schematic with a couple of changes and will build one for 5v.

This program is designed to promote amateur radio to the masses, helping eliminate a possible entry barrier by providing new hams with everything they’ll need to get on the air at a very reasonable price. Jumpstart Packages will be provided to new hams who meet eligibility requirements.
New hams who have recently obtained their first license from the FCC may apply for a welcome package. Applicants must apply within six months of the license grant date per the FCC records.
The eligible ham must have a QRZ user account and be able to log in and apply for the program. Certain types of identification, including a photo ID, will be required. This information is not shared or exchanged with any party and is used only to validate eligibility under this program. Additional shipping charges may apply when shipped outside of the contiguous 48 states.
This program is available exclusively to USA-licensed amateur radio operators.
