Reading DTMF tones from a Motorola Razr V3 with a Z80 system
This is a demonstration of a bonus feature I built into my Z80 rotary phone system. Basically, I can wirelessly enter data with a Motorola Razr V3.
How does this work? Basically, the phone system has an inductor pickup coil that can detect low frequency (audio range) radio signals. When I push a number key on the Razr, not only does it make an audible beep sound from the earpiece, but the earpiece also emits a small radio signal at the same frequencies, which I can then detect with the pickup coil.
The inductor pickup coil is input to an op amp circuit to amplify the signal, which is then input to an MT8870 DTMF Decoder chip. The output of the decoder chip is connected to channel B of the Z...

Z80 CPU Bluetooth Rotary Phone
Просмотров 1,2 тыс.3 месяца назад
This is V2 of my rotary phone system. The V1 system was built in 2017 and used custom interface circuits, an Arduino, and Fona 2G GSM modem from Adafruit. It worked well enough at the time. You can easily find old videos of it on my channel. Due to T-Mobile gradually reducing 2G service, V1 of the rotary phone lost reception and was unusable from about 2021 until a couple months ago when I comp...

Steampunk Digital Clock

My latest project... it's a digital clock timed by the ticking vibrations of an antique pocket watch movement. It uses a piezo electric sensor epoxied to the back of the watch movement to pickup the vibrations, which are then amplified, denounced, and converted to a digital reference signal of 5 Hz. The circuit then uses some TTL logic and a decade counter to convert that 5 Hz signal to a 50 Hz...

    Well done on making your own Z80 machine. I’d love to connect a HC-05 to the TEC-1G. We already have a serial protocol in place using bitbanging to a serial to USB uart, but going wireless would be very cool. Do you have any design docs or code for talking to the HC-05?

    • @danebeck7900
      @danebeck7900 4 месяца назад

      Sorry for the slow reply, I rarely check comments these days. If you're doing a Z80 to HC-05 serial connection, just skip the USB altogether and use the serial protocol. If you get a Z80 SIO or DART you shouldn't need to bitbang serial (but you can if you want to). The HC-05 needs to be set into command mode and sent a series of serial commands to establish the Bluetooth connection, then it needs to be put into data mode. It works very well once you get the HC-05 initialization right. Pretty sure the HC-05 documentation specified the command set. Send me an email and I can send you the HC-05 ASCII commands I used: danebeck84@gmail.com

      One of the great things about Bluetooth is it doesn't go obsolete. That's for 2 main reasons: 1. Because Bluetooth is designed to be backwards compatible. That's why a 2 year old laptop and a 20 year old flip phone can connect. 2. Because it's a local connection between the two devices and doesn't rely on any outside networks. So even if there's no cell reception or WiFi, Bluetooth will work just fine.
