Category: 🖥️ - Difficulty: 🔴

Write a useful computer program!
The program can be built in any programming language, written or graphical. If you have never programmed before, here are some ideas of what your program could do: In order to get started quickly, here are some websites where you can write and run code immediately, without the need to install anything:

2025-05-13 09:50:44yo3gnd@mastodon.radio31Success!I made some software rendering pixel fonts into audio and I TXed a #qrss signal. RXed my own on the grabbers, and the common ones on 30m. Does this count as a threefer for the #hamchallenge? (44, 46 and 48). @hamchallenge #HC44S #HC46S #HC48S
2025-05-25 17:13:26n8dmt@mastodon.radio21Success!HC46S Write a useful computer program. Created SW interface to read a Mini-Circuits ZX47-55 RF Detector using an Digilent AD3 interface module. Used free LabVIEW Community Edition for programming environment. SW provides a nice stable readout of the detector in dBm. Simple calibration values yield pretty-close output level & temp display. This will be a nice addition to the home lab (once the detector module is mounted onto an AD3 interface board). #HamRadio #RFTest #Digilent
2025-09-07 13:28:13g7kse@mastodon.radio35Success!Its raining here and I've got domestic jobs I don't want to do, so thought I'd lose several hours trying to write a basic programme for I thought the easiest thing was to try and display the HF data in a terminal window with python. Writing code isn't that easy for me and I needed a lot of help & I mean a lot . Still , its done and HC46S is my reward.So to celebrate I bought a RPi Pico and an ePaper display but that'll lose the colour.see here - https://codeberg.org/g7kse/TerminalDash
2025-11-10 08:35:31ian@mastodon.radio38Success!#HamChallenge week 46 is to write a useful computer program., so I'll take this opportunity to announce the release of v1.0 of Spothole!Spothole is a web-based DX cluster that can aggregate data from over a dozen sources. It provides a geo map and band map, includes alerts, and has its own well documented API that others can build on. It's Public Domain licenced.Use it: https://spothole.appRead more: https://ianrenton.com/projects/spothole/Source code: https://git.ianrenton.com/ian/spotholeHC46S
2025-11-11 19:14:26mcdanlj@social.makerforums.info18Success!RE: https://social.makerforums.info/@mcdanlj/115525717290589240I just published source code for my new very lightweight, command-line-only alternative to WaveLogGate. Since I wrote it in Go and can't name things well, I am calling it WaveLogGoat. I'm now using it to link my IC-7300 to WaveLogI do expect to later to binary releases of it for most any OS/architecture combination supported by Go, especially if someone steps up to test the hamlib / rigctld support that is completely untested right n

2025-11-16 22:02:49DJ5CW@social.darc.de29Success!Over the last few weeks, my go-to site for quick #RBN spot lookups (https://skimmer.g7vjr.org/?dx=so5cw) was changed to summarize spots from different skimmers over time and bands, which I don't like. So I wrote my own small script which produces basically the old format: https://rbn.telegraphy.de/lite?dx=SO5CWI know there are many more advanced ways to query RBN data, but I occasionally need it the "KISS" way. This tiny PHP script is also my entry for week 46 ("Write an useful program")... #HC4
