B4 Assembly Adventure
Log from Beeping, Blinking Business-card Badge (B4)
The LPC8N04 is only available in a QFN so hand assembly is not trivial. If you can live without sound, NFC EEPROM chips like the one I used in B3 are available in much more hobby friendly packages.OSHPARK's flex service provides 3 copies of your...

Op Amp Challenge Accept-ed(?)
Log from Single Comparator/Op-Amp[?] Toggle-Flip-Flop
I do not at all consider myself good at analog circuitry. It's one of those things that intrigues me conceptually, but has mostly eluded me in the few times I've found the time [and courage!] to try again over the last three decades.Thus, seeing mention...

New Boat, New Autopilot - using an old laptop mainboard!
Log from OpenCPN Chart Plotter /w Autopilot and Waypoints
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....

Interfacing ternary and binary components
Log from Homebrew ternary computer
Ok, now it is kind of proven that binary CPLD (or FPGA) may implement ternary logic, but how we can integrate it with "true" ternary components, especially when CPLD is 3.3V and TRIMUXes are -5V and +5V? Answer is DG403 chips may do the job: Because...

Cold Weather and AA Batteries
Log from Mailbox Sensor
Well, this might set a record for the shortest working project that I thought was 'done'. Turns out AA batteries drop in voltage when cold a lot more than I expected. After some very mild cold weather (barely below freezing), the voltage dropped enough...

From the community #4: "DIY"ed SG-90 Stack-chan!
Log from Stack-chan - JavaScript driven super-kawaii robot
Tomorrow56 (@tomorrow56) is a professional electronics engineer, who sells a lot of original PCBs as ThousanDIY, and he is also the originator of the SG-90 compatible version of the stackchan. (https://twitter.com/tomorrow56/status/1415328179695194114?s=20)...

Understanding how the computer works
Log from Apollo Guidance Computer
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...

The actual informations
Log from Extension card for TDS3000 scopes
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....

back-"burner"ed for a bit, plus some inspiration
Log from CD/DVD mechanisms and cartesian thinggie[s?]
@Stefan Lochbrunner has thrown up some of his #Computer Numerical Considerations, definitely worth a look for some inspiration. Which is timely, because, if you haven't noticed, this project (at least on my front) has been sorta thrown on the back-"burner."...

♫ Flash! (aa-aahh!) Saver of the Usersettings! ♫
Log from HP 82240B IR Receiver and Printer Interface
Summary:It occurred to me that it would be useful to save some configuration in a non-volatile manner. This board and this chip does not have any conventional non-volatile storage (e.g. EE or external serial EE), but there's plenty of pages of unused...

Finally, some publicity!
Log from RasDash
An article recently published on MOONGIFT, a Japanese developer site, has showcased RasDash! The article is entirely in Japanese and Google Translate won't accept the URL as it has special characters but YANDEX does. Below are some links and a basic...

Comm protocol between camera and drone controller
Log from Reverse Engineering a ProMark VR Toy Drone
Initially I thought the data stream from the camera board to the quadcopter controller was PPM. This signal is only active when the app is running and the on-screen controls are brought up. The quadcopter has to be power-cycled in order to be controlled...

B3
Log from ComputeDeck-B3
I am putting together the project video atm but wanted to share some photos of the completed build. I'll go into detail there about why I made the chording device and how to modify what I've made for your own hacking needs. You can see the output...

Reading "Microlaunchers: Technology for a new Space Age" by Charles Pooley and Ed LeBouthillier
Log from We Should be Free to Tour the Solar System
Point 1: Rockets ranging from gross mass of 100Kg to 1000Kg are capable of orbital insertion. (Microlaunchers)Point 2: DIY space explorers must aim for > LEO due to the fact that LEO is crowded, regulated, and a little boring by now (my paraphrase).Point...
