I've made a laser cut prototype of the board. It's the led diffuser an the top face of the board. I will start to a 91 cells board, due it fits well in a A4 sheet and I could make a single PCB with all the electronics. This will help to develop the software,...
Version 2 is a major upgrade for our project. We connected with Michael at maskau.dk and started to learn some real things about working with these gas sensors. Michael's page on electronic noses is fascinating, and he's able to get some incredibly impressive,...
The first part was remove the Head and arms of the toy cause they weren't match to the aesthetics that i wish for the project: Fully Assemble toy The head removedAfter that i gave it a primer painting, the first ideia was give it a black painting after...
Reading this Japanese article on a kit sold in Japan to build a Z80-MCB, I realized the presence of a possible bug seeing this two images: As you can see, there is a Z80-MCB without any Virtual Disk or RTC attached and in the resulting screenshot the...
There are two ways to get to the Z80 bus for external operations. RESET* - Clears PC and sets address/data bus to Hi-ZBUSREQ* - input - Address, Data, MREQ*, IORQ*, RD*, WR* to HiZBUSACK* - output indicates that BUSREQ* signal was performed (Hi-Z busses)...
Today I'll share Thor's Forward Kinematics calculus. Forward kinematics allows to compute the position of the end-effector from specified values for the joint parameters. In order to resolve the Forward Kinematics I have used the Denavit-Hartenberg parameters....
Now that we can read SD cards and have an I/O interface in place from the Z80 to do I/O mapped access to the SD card it's time to hook the two pieces together. To do this we will need to look closer at how Grant's code request blocks. The loader...
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...
First up, the latest revision. Small changes from the last version including tightening up various current loops in the buck converter and moving the battery-side transient TVS diode to the anode side of the reverse-polarity protection diode to...
In a previous log (https://hackaday.io/project/11225-a-new-high-accuracy-tilt-sensor/log/46957-theoretical-background-of-the-linear-fcdt) I showed that in case oftilt degrees, the volume of ferrofluid found in the (left) secondary coil is:And in case...
Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...
04.22.2014 (Kittan) Sometime I still need to redo the base of the frame, and run the USB/serial lines for all the touch interfaces and optical drive, but that's pretty much it. All screens are mounted, as well as the keyboard, optical and the control...
Below is a picture of a patch that gates the input to the ADC so that it is only looking at the value from the EC probe at the end of the square wave pulse, after the initial transient has settled out. It works really well, dutifully recording the voltage...
Here's a quick video showing rebuilding the legs on the mjbots quad A1. Everything is upgraded from the A0, including 12 qdd100 servos, a new body, new legs, and a new power distribution board, and a new raspberry pi daughterboard.and a pic of...
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
