Hello from 1949 new Era on radio technology, "don't use it, wear it" the Slogan come from technology wearable radio hat from 1949. The hat come with radio, audio vacuum tube amplifier and battery pack. Now i want make this one, and this is all step.. happy making
Supplies
-Vintage Safari hat
- electronic Moduls for radio, or just use a diy radio kit at online store
-mini amply power
-5v charger module
-stepdown 3v module
-dc 6E2 audio tube 2x
-2x battery 18650
-couple of wire
-cap of jar
-coil
-Earpad
-electronic tool
Making Radio
- Assembly the radio kit, the kit come with a cmplete electronic modul just follow the intruction paper who come with.
- soldering all electronic part to pcb board, becareful, you don't wan a mistake, because the radio can't turn on if have any mistake, yse a diagram and data sheet for guide you.
- test funsion if yiu have already woth the mini radio.
Making Audio Tube
-Soldering All item part to pcb board
-makesure installation correctly
- you need 2 pcs
Making Headset
- this step you need 5w speaker, earpad, plastic cap, hard spon.
-soldering wire to speaker
-install the earpad to speaker with hot glue
-use a plastic cap to cover speaker with hot glue
-Cut a 3cm hard spon for making headset arm.
-done
Making Antenna
-Cut the plastic cap, just need a side circle (picture 2)
-Wrap the coil a couple warp around the cap
-Use tape to keep the coil in place
-done
Assembly Radio Hat
-This Step you need the safari retro hat.
-Prepare the hat and all part who has we create before.
-first we install the audio vacuum tube, make a pin hole on the hat same with pin on the tube, Plug the tube pin through the hat, on inside hat plug the board with insert the pin tube to adapter pin on pcb board, do same thing with another tube.
- install the amply power, first modif the durection potensio on the pcb just bend the pin potensio, So that the face of the potential is facing up, make a hole at the front of hat, insert the shaff potensio on the hole, screw it and install the knob. Look a picture.
-Instal the antenna, make a pin hole insert the coil to hole and install the circle antena on the back hat using hot glue.
-Install the speaker, install the headset we make before to the right side oh the hat, use hot glue or screw.
- for Radio is differen part with hat, use 2 battery 16850 for suply power, look diagram radio part, you need step down to 3v for powered radio, and charger modul becase the battery permanently soldering, so we need charger port. The 7,2 V battery output use to powered the audio tube, you need 5 pcs wire @1 meter, the wires are used to connect the radio to the hat, 2wire is power, another 2 wire for audio and 1 wire for antena.
-hat wiring, look at hat diagram, the 7,4v from battery input to power on amply power module and output go to power input the audio tube. Audio wire from radio go to audio input on audio tube, the output to speaker. Only use 1 audio tube in this tutorial because just use one speaker or mono. If you use stereo use of all audio tube, last wire connect to antena hat.
- All done...
Thankyou
