I’ve been eyeing up the dEEbugger (https://github.com/S-March/dEEbugger_PUBLIC) and was wondering if anyone would be interested in participating in a bulk buy of the parts required to build it?
It’s a rather basic wireless oscilloscope (and a few other things) built on an esp8266, designed to fit on a keychain. The github page goes through its features a bit better than I can.
I’m looking for people to express their interest in these in the thread and how many they’d like, once all the parts arrive I can either give you the parts in a baggie or we can grab some solder paste and have a reflow-party at the space.
I’ve updated the price, after the first 10 orders the price before shipping has come down from $12.47 to $11.358 for each unit.
I’m gauging interest on whether or not to buy another 10-15 of these for a series of 2-3 reflow (oven and hot air) soldering workshops. Will update price accordingly once I know how many will sell.
I’m the creator of the dEEbugger, stumbled on this thread while looking at traffic to the repo. I am really excited that you all liked the project! I figured I’d drop in to answer any questions you all may have.
To answer your questions @jace, this can be used on your phone/laptop/tablet/anything that has an internet browser. The res of the ADC is 12bit, one channel is set up to be a 64V channel, the other set to 4V channel.
As for the internet portion, the device supports two WiFi modes. It normally boots in AP mode which means it will create its own network, named “dEEbugger”, that you will be able to connect to. From there you navigate to the IP address 192.168.4.1 and you will be up and running. If you do, however, want to connect the dEEbugger to your own network, jumper the the SDA pin to ground. It will then boot up with a provisioning web page that will allow you to enter in your network info. Once connected to your network you can either go to dEEbugger.local if your device supports mDNS (sadly android doesn’t) or you can go to the IP assigned to it.
Awesome thanks for showing up Wanting it to use for control system commissioning, ie, sit at my computer, drive a point on/off or 0-10v and make sure the signal is coming through.
Does it have the possibility of a analog out, or digi out?
@jace - If you looked at the schematic or even the picture in the above posts (no need to even click away from this page) you would see the device has an ADC but no DAC and the labels on the PCB show that the digital outs seem dedicated to I2C.
So you COULD extend it yourself for analog or digital I/O (using I2C) but it does not come as standard.
@jace as @andrew1973 mentioned, there are 2 pins dedicated to the I2C lines that could** be used for an output.
The problem is that the ADC is an I2C based chip so if you were to switch the pins over in software, you would still have access to the web interface or the USB to UART converter, but no longer have access to the ADC portion.
The other option is to use an off board IO expander like this one. You could just tie the SCL and SDA lines to the ones on the dEEbugger and write some code to trigger some of those pins when you need it!
Hey I’ve got a bunch of ADS1216 24 bit adc boards with msp430 and zigbee wireless. Could wire on a USB to serial port and da da. . It has two channels for measuring a thermocouple and mV input.
