July 2023 Archive: Practical how-tos and tech notes

July 2023 brought four hands-on posts that answer real problems fast. If you want to play other videos while streaming, set DMX addresses, spot where broadcast gear is heading, or build a simple drone antenna, this month’s roundup puts clear, usable tips in one place.

Quick how-tos from July posts

How to play other videos while live on YouTube: use OBS (Open Broadcaster Software). Create a new Scene, add a "Media Source" for the video file or use "Window Capture"/"Browser" for online clips. Mute the video if you only want visuals or balance audio with your mic using OBS audio mixer. Test latency and check copyright before you stream—copyright takedowns happen fast. Also run a local recording to verify levels and transitions.

How to set a DMX address for stage lights: first, know how many channels your fixture uses (1, 3, 6, etc.). On the fixture or menu pick the mode that matches the channel count. Then set the starting address using the fixture’s dipswitches or onboard menu so it lines up with your console channels. Chain fixtures using XLR DMX cable, and always test by moving one control on the desk to confirm the correct light responds. Label each fixture with its address once it’s set—saves time during shows.

What is the future of broadcast equipment: things are moving to IP-based systems, cloud workflows, and smarter tools. Expect more use of SMPTE ST 2110 for video-over-IP, cloud-based editing and distribution, wider 4K/8K adoption, and AI tools for captioning and QC. For now, focus on hybrid setups: keep reliable SDI links for live stages, but add IP for flexible routing and remote workflows.

How to build a simple antenna for an RC drone: keep it basic and measured. A quarter-wave antenna length in meters is 300 / frequency(MHz) / 4. For 2.4 GHz (2400 MHz) that’s about 0.031 m or 3.1 cm for a quarter-wave element—many DIY builds use simple whip lengths around that size or design a small dipole. You’ll need coax, a connector matched to your transmitter, cutters, and a soldering iron. Strip carefully, solder the core to the center pin and braid to ground, then heat-shrink the joint. Test range in an open area and adjust length slightly if you see dropouts.

What to take away and next steps

Pick one task and try it this week. Add a test Scene in OBS and play a short clip. Check a fixture’s DMX address on a small rig. Watch one IP-based broadcast demo online to see how routing works. If you build an antenna, start with the quarter-wave formula and test in a safe open space. Each post this month gives a short path from problem to working solution—practical steps, not theory.

Want me to expand any of these into step-by-step guides with photos or checklists? Say which one and I’ll pull a full how-to together next.

How to set a DMX address for stage lighting equipment?

Setting a DMX address for stage lighting equipment is an essential task for any lighting technician. First, you need to understand that each lighting fixture on a DMX universe requires a unique address. The process involves selecting the right mode on your lighting console, then assigning an address to your fixture. Remember that the number you assign should correspond to the DMX channel you want the light to respond to. It may seem tricky, but with practice, you'll be setting up your stage lighting like a pro in no time!
