New Product Ideas / Re: Pre-soldered Breakout Wire...
Last post by Duztin - Today at 08:52:04 AMQuote from: bibletech55 on October 26, 2025, 06:58:20 PMHas you considered using spring-loaded (push-in) terminal blocks instead of screw terminals? I've seen them used on other micro-boards; they seem like they might put less mechanical stress on the solder joints since you aren't torquing a screwdriver against them. Would those fit the standard 0.1" spacing?QuoteGreat find on the 5-pin screw terminals! That Amazon bundle from Cermant is a steal at $0.45/piece. Definitely beats the Adafruit/Digi-Key price.Thank you so much! I appreciate the compliments!I double-checked that Amazon Cermant link, and strangely enough, that product page seems to only sell 2-pin screw terminals now. Plus, as a fair warning to any interested buyers, a lot of the reviews for that product are quite negative.
These screw terminals may work well! From my experience, as I have used these terminals myself, the screws are quite small, and the screws are also flathead instead of Phillips. But these terminals do function well in terms of conducting current, even after soldering! These terminals work best under low mechanical strain (don't pull any attached wires very hard). Still, I suppose less mechanical strength is to be expected since the terminals are so small.

New Product Ideas / Engineering Excellence in Rota...
Last post by colemanronnie - Today at 01:56:41 AMThe 13b engine represents a milestone in automotive engineering, delivering performance through an innovative rotary combustion system. Unlike traditional piston designs, this engine relies on triangular rotors that spin within a specially designed housing to generate power. This design results in smoother combustion cycles, reduced vibrations, and a compact engine form factor. The 13b engine was engineered to provide exceptional power output while maintaining a lightweight structure, making it ideal for performance-driven vehicles.
Mazda perfected the 13b engine with a strong focus on durability and heat management. Specialized cooling channels, oil injection systems, and reinforced rotor housings were implemented to maintain stability under high-performance driving. This attention to detail allowed the engine to perform consistently in both street and track conditions. The turbocharged versions of the 13b engine further improved power capabilities, delivering aggressive acceleration without compromising engine balance.
In professional motorsports, the 13b engine has proven its reliability in endurance races, time attack events, and drift competitions. Its predictable power curve and rapid throttle response give drivers precise control over vehicle behavior at high speeds. The distinctive sound and performance characteristics have made the 13b engine a fan favorite at automotive events and racing circuits around the world.

General Discussion / A High-Performance Icon in Rot...
Last post by colemanronnie - Today at 01:54:32 AMThe 13b engine is considered a masterpiece of rotary engineering, designed to deliver exceptional performance through a compact and lightweight structure. It operates using rotating triangular rotors instead of pistons, allowing it to produce high power figures from a relatively small displacement. This innovative layout gives the 13b engine superior balance, smooth operation, and an extremely high redline, which sets it apart from traditional 4-cylinder and V6 engines. Engineers designed this engine to maximize airflow, combustion efficiency, and thermal management.
One of the most remarkable characteristics of the 13b engine is its turbocharging potential. Twin-scroll and single-turbo variants of the engine have shown the ability to produce impressive horsepower figures, making it a favorite in both street and track applications. The lightweight aluminum housing and compact design contribute to better vehicle weight distribution and overall handling performance. This has made vehicles equipped with the 13b engine highly competitive in racing environments where balance and agility are just as important as raw horsepower.
The popularity of the 13b engine also extends to the drifting community, where instant throttle response and linear power delivery are essential. Professional drift drivers often choose this engine for its predictable power output and ability to maintain high RPMs during extreme driving angles. The sound signature of the 13b engine is another factor that has helped it gain legendary status, producing a unique high-pitched exhaust note that is instantly recognizable among car enthusiasts.

TinyTV & Tiny Video Player / Re: TinyTV 2 - always random s...
Last post by swash1 - December 06, 2025, 05:53:20 PMHi, same problem months later (Dec 2025) trying to get TinyTV 2 to start at the beginning of video 1 on power-up. I've updated the firmware and adjusted the settings for randStartTime and randStartChan to false, per the help page. (I even tried renaming randStartChan to randStartChannel, the way it's listed on the FAQ/help page). I also tried per a suggestion here to make the file read-only. I even tried turning off loop in case that locked it in to where it was when it powered off. No dice.
Anyone find or figure a solution? I'd really like this to start at the top of channel 1 whenever powered on.
Otherwise - loving it!
Thanks

I'm using HandBrake to convert my videos from MKV to MP4 first, with a resolution of 216 × 134 pixels, a variable bitrate, constant quality set to RF 20, and the audio track set to AAC Mono at 128 kbps. After that, I convert the file with FFmpeg using the following terminal command on macOS:
What works even better for me is adding the quality parameter (-q:v) and setting it to 1, which noticeably increases overall sharpness. For most videos, setting it to 2 should be fine as well. Also there is a volume parameter (-af "volume=[val]dB") which might come in handy:
Interestingly, setting the audio sample rate to 20 kHz works just as well as 10 kHz, and my TinyTV 2 still plays it without any issues. I thought higher sample rates weren't supported, but it seems like they are!
