Project Ideas
Business
Jobsite Comms Rental Kits
Offer turnkey rental packages of DEWALT Business Radios with USB-C RSMs, pre-programmed channels, labeled chargers, and high-vis vests with epaulet mounts. Include on-site setup, quick-start training, and next-day swap service. Target general contractors, roofing crews, and roadwork teams who need reliable, water-resistant, hands-free comms.
Event and Festival Comms Support
Provide staffed communications for festivals, marathons, and fairs. Each staffer gets an RSM for clear PTT in crowds, with optional VOX for bike marshals. Offer frequency coordination, spare batteries, hygiene covers, and an on-call tech to manage gear. Bill per day with add-ons for recorded traffic and post-event incident reports.
Warehouse Voice-Pick Enablement
Deploy radios plus RSMs configured for VOX to enable hands-free picking and forklift coordination. Train teams on mic placement, VOX sensitivity, and standard callouts. Bundle with shoulder mounts and cable routing kits to minimize snags. Sell as a monthly service including equipment, maintenance, and periodic retraining.
Guided Outdoor Tours and Field Teams
Rent compact comm kits to hiking guides, birding tours, and outdoor education programs. RSMs clip to straps for quick PTT without shouting across trails, and water resistance handles weather. Offer day-rate kits with laminated comms etiquette cards and optional audio logging for guide debriefs.
CERT/School Safety Comms Packs
Assemble Pelican-case response kits for CERT teams, schools, and property managers: radios with USB-C RSMs, labeled roles, spare accessories, and quick SOP cards. Provide annual service contracts for testing, battery rotation, firmware updates, and staff drills. Market as a preparedness and compliance solution.
Creative
MOLLE Epaulet Mount and Cable Routing Kit
Design and sew a high-visibility vest or jacket epaulet with MOLLE webbing and a reinforced tab to perfectly accept the 360° swivel clip. Add low-profile elastic loops down the shoulder to guide the coiled cable so it stays snag-free. Include a quick-release loop at the chest for fast handoff of the mic. Great for construction sites, bike patrols, and event crews.
VOX Wind and Noise Shield
Build a compact wind and noise shield that friction-fits or Velcros over the mic housing to reduce false VOX triggers in wind or on loud jobsites. Layer open-cell foam, a 3D-printed micro-cage, and faux-fur (deadcat) for wind attenuation while keeping water-shedding. Test with different densities to balance clarity and ambient noise rejection.
Mechanical PTT Foot Pedal
Create a non-electronic remote PTT by using a small foot pedal connected via a bicycle brake cable (Bowden) to a 3D-printed clamp that physically presses the PTT button. Ideal for camera ops, climbers, or forklift drivers who need hands-free transmit without relying on VOX. The clamp should be padded to avoid scuffing and quick to remove.
Clip-on Audio Logger Cradle
Design a clip-on cradle that positions a tiny field recorder or smartphone mic right over the RSM speaker, allowing clean capture of radio traffic for training or incident documentation. The cradle should avoid blocking the speaker port and maintain water runoff paths. Add a small rubber standoff to isolate vibrations.
Color-Coded Faceplates and Hygiene Covers
3D print thin snap-on faceplates or silicone-cast skins that fit over the mic front, in color codes for roles (safety, logistics, security). Add a removable wipe-friendly hygiene cover for shared devices. Include a small nameplate window for labeled inserts so gear returns to the correct person at end of shift.
