Jasmine Brackett Hello Everyone. Welcome to this week's Hack Chat! !!!Bhavesh Kakwani WooShulie: Welcome!! We have tons of questions in our sheet already! https://docs.google.com/spreadsheets/d/1ZHahHN4kU0YBjMgrZMU9ntrmdDD8JOUmpHX2mR6Ok0w/edit#gid=0Jasmine...
Just a quick update regarding the screen of this device.i have a lovely little 5" LCD display complete with driver board which I was going to use for this build, but I have received some good news!I stumbled upon a new lines of touchscreens being released...
After fitting the belts i tested each axis to find that the Z stepper motor was only switching one set of coils on, i searched the PCB for dry joints but had no luck. Option 1 is to buy another driver and re flow it onto the PCB Option 2 is to buy a...
First test of the light setup! LEDs are all driven in series hooked up to a cheapo 700mA constant current driver and a 31V power supply I found at the swapfest. To emulate a Hue bulb, I'm using a Mesh Bee with firmware from PeeVeeOne. It outputs a PWM...
(Apologies to pop culture, as usual.) I ordered the LCD kit today. Hopefully THIS time the seller will have understood correctly that they need to cover the driver board with something not conductive so that static from all the bubble wrap doesn't...
I ended up using the key combination for On and Mode (it seemed appropriate) to change the mode, which basically is between TI-83 keyboard mode for the TI-83 emulator and Regular mode which allows through various submodes access to just about all of...
When I set about this project the first thing I wanted to work out was what LED I was going to use, as this would drive the requirements of everything else in the project, driver, lens, heatsinking, etc. Due to personal preference I decided that I wanted...
In the last log I left-off with a 2-D printed version of a printed circuit board I designed in KiCad which was enough to confirm that the board I was designing would fit into the board I’m designing it for. This felt like a lot of progress! However there...
So today we finally had a chance to work on the first control board, the radio and I/O shield for the Carambola2.I only learned how to solder SMD components myself 6 months ago, so this was a good chance to teach Mr.14 as well :-)Everything lined up...
With the compass functionality tested on a breadboard, the next step is to transfer it to a universal prototyping board, adding a status display and IO expansion ports to drive a LED ring that simulates the horizon. For the board, I am going to use the...
You can find out more about HiCAT Livera here. I finally have all the components that I need to start Phase 2. The Livera and Motor Driver are shown below: The objective of this Phase is to convert the Meccano MAX into a vision-based robot using HiCAT...
Nov 23:I'v started assembling the PWM power converter. During which I realized that when I modified pwm genorator to run on 5V, it was in part to make it match the error amplifier output, that whole transistor stage on the end of the error amp isn't...
Hi guys! Sorry it's been so long since I've updated. Believe me, I haven't forgotten. I've been hard at work! As you may know, the PortableSDR was selected as one of the 50 semi-finalists for the Hackaday Prize! Thanks everybody! Wish me luck!The next...
I was setting up the spindle driver, which has zero docs, this is my journey. I suddenly decided to vlog it and then tried to figure out the best way to do it, which lead to all sorts of things and make it a 3 times longer process. Also my shuttleXpress...
I used an FPGA in my original design but it has proven to be complicated and expensive. The Xula LX25 is well documented but produced in low volume and seems to be no longer for sale. Luckily, Henner Zeller made a polygon laser scanner, the LDgraphy,...
