LCD Set up
Log from Viper PRO
OKAY, now that we have the raspberry set up, we can star the assemble of parts.Let's make the LCD work!First thing that we need is a adapt board ( its on components list), so we can solder every pin on 40 pin connector to the 40 pin GPIO on raspberry.Now...

Revision 7 production progress
Log from wESP32: Wired ESP32 with Ethernet and PoE
After waiting for four months since I ordered them, Mouser finally shipped the SI3404A PoE chip to my CM, so they have started production. I received this picture of the new PCBs: Looking good. I think there shouldn't be confusion about which...

More pins, more serial and a wall
Log from Extension card for TDS3000 scopes
Before going to the serial port subject, I took some time to analyze the display pins. The clocks were easy and matched what I found about some simple color LCD datasheets DotClock : pin 2 (25MHz, 50% duty cycle)HSync : pin 3 (31.5KHz, 88% duty cycle,...

Keeping the Tile Interface?
Log from TMD-2: Turing Machine Demonstrator Mark 2
IMHO the best part of TMD-1 is the tile interface. Programming the machine by filling out the State Transition Table with "special" tiles feels natural, something about the tactile nature of the process I guess. It's also a lot of fun. I've had a few...

A more reasonable touchscreen controller IC
Log from Put a Raspberry Pi CM4 into an original iPad
In my first project log, I had designed a PCB for interfacing with the touchscreen digitizer, based around Atmel's mXT2952, which was the only device I managed to find that had:datasheets availableenough drive / sense pins for the iPad's screen (40 drive,...

The Hackaday Prize Video
Log from The Open Book
I’m going to be honest: I had a whole long post I wanted to write this week about ideas for working with writers, a whole “Open Book Quarterly” where, if this thing took off, we could use royalties from the book to commission short stories,...

Of IVL2-7/5s
Log from VFDuino
To set the scope of what I am and am not going to talk about here:I am going to describe the pinouts on the IVL2-7/5I am going to talk more about what I did to get it workingI am going to talk about how to test your VFD to make sure it behaves as you...

Testing the 14500 HAT-like UPS supply with high current demands
Log from Single-cell Li-Ion Powered UPS for Raspberry Pi
First of all, let me clarify that with normal 14500 cells in general, a heavily loaded (with attached USB devices) or tasked (running all cores to the max) Raspberry Pi Model 3 will not run for long on these cells, if at all. Regardless of the capacity...

Fried Green LEDs
Log from Bullet Movies
I knew it would happen at some point. I killed some 30x30 mil LED chips in this stock 10W green package. The remaining good ones still light off DC: Actually two others in the left string also appear at higher currents; before the "event," they all had...

New Blackbody Radiator and Lepton Accuracy testing
Log from Lepton 3.5 Thermal Imaging Camera
Trawling eBay netted a reasonably inexpensive Accuthermo FC100D TEC (Peltier thermo-electric cooler) controller mounted in an enclosure from Wells-CTI with a 12VDC 8A power supply and TEC H-bridge driver. The FC100D uses PWM and bi-directional...

03 – cutting costs
Log from Universal undervoltage lockout up to 34V input
What is the aim? This log is all about: How can we make the whole board cheaper while keeping all the features and not killing its safety functions. This all refers to the early v0.2 version which is by no means optimized yet! Ways to cut costs I try...

Motor Control and Current Measurements work very well.
Log from Open Concentrating PV Solar Tracker Controller
Motor controller and current measurement This will be a long log, so I want to summarize: The motor controller of the “single board” works as expected and we can get a current measurement which is good enough to detect blocked or damaged...

Matrix
Log from Alpen Clack
The favorite microcontroller for all things USB, such as keyboards, joysticks or mice, is the good old ATMega 32U4, well known from the Arduino Leonardo. Of course I don't plan to stuff an Arduino-footprint board inside my keyboard, I need a smaller...

Mr. Gibbs 2.0 first sail, miserable failure
Log from Mr. Gibbs
Well it's a good thing I wasn't relying upon Mr. Gibbs to navigate the ocean! The system had some issues, to say the least. The bad news is I didn't get to gather any usable data over the weekend, and we did not actually get to use the system at all....

Well how in the world are we going to build a Spectrum Analyzer?
Log from Affordable Spectrum Analzyer
My lab partner, Andrew, and I were faced with deciding on a senior design project to complete our degrees at Lehigh University. Not wanting to waste an opportunity (possibly my last) to work with someone as smart as Andrew, I wanted to take on an ambitious...
