At #CCCamp19 I saw a pair of #FPV googles with probably the lowest latency anyone has ever experienced. Should be about 0ms due to the fully analog signal pipeline. Sadly I didn't remember the name of the creator, do you know? (Yes those are old CRT camera viewfinders)

The two hardest parts of any project is the first 3% after the initial idea, and the last 3% before completion.

rv003usb - bit banged USB on the ch32v003

I believe I now have made the cheapest USB enabled microcontroller....

Does anyone know of a system that does firmware flashing over HID feature requests? I can design my own but if someone's already doing something I'd like to avoid work duplication.

Does anyone know how to get China to pump out your dev boards and dump them onto aliexpress, etc? I have some gerbers for CH32V003+USB, I just don't know who to send them to to get this in the hands of more people!

IT ENUMERATES! github.com/cnlohr/rv003usb Still need lots of work to make a self-hosting arduino on this 10¢ #riscv, the #ch32v003 with the bit banged stack! Thank you so much to the whole team that came together to make this a reality.

Hiiiii, It's the new product again!😀 CH32V035 is a RISC-V MCU with built-in USB PD PHY. So If you are familiar with the coding habits of general-purpose MCU, now you can use this single MCU to design your USB PD products. DM me for coupons now :) youtu.be/zcvhnePzfbA

New open source solution time! #NFC #riscv You can design the whole NFC project without additional NFC chips by using @WCH_TECH @risc_v or arm MCUs. This repo released souce code and schematic&layout, please check it out!!😀 github.com/openwch/nfc

We're due for a rebound from endless padding and three buttons per page of settings.

It's not #esp32 - but for 10¢ on the #ch32v003, I will take a stable parallel DMA output capable of controlling 8 GPIOs 100% interrupt driven in software, at 4MBytes/s. This is a huge boon for complicated LED controllers, motor controllers, and systems that need weird protocols.

Habe auch zusammen mit @[email protected] ein gebrauchtes (zerbasteltes) #PocketQuad aus Nürnberg abgeholt, damit er daraus ein Camp Fahrzeug basteln kann. Die originalen Warnhinweise und die hinteren "Kotflügel" sind auch super xD Es wurde zerlegt und der Verbrenner (1/2)

Pocket Quad im "Originalzustand" vom Verkäufer. Zugeschnittene Eimerhälften als hintere Kotflügel, eine eigene Motorhalterung aus einer Aluplatte und der Tank ist mit einem Expander befestigt.

Bought a #Mercedes #48V #MHEV #startergenerator for #reverseengineering. The specs are impressive, especially for the price point of a few hundred euros. - 48V / ~200A - 12.5 kW peak - 165 Nm peak The main difficulty lies in finding out the #CAN commands for (1/2)

Attached: 2 images After much digging I at least found the pinout in some Mercedes shop software. But unsurprisingly the #startergenerator didn't send any messages on its own on the #CAN bus when...

The seat of the #ePocketBike really needs some fixing. I want to repair and reinforce that plastic piece (some metal band and fiber weave?) and re-do the foam part so it's actually cushy again. No real experience with either of that. First I need a plan and what materials (1/2)

I noticed, that my brain tries to be more and more perfectionistic again regarding my post quality, thus leading to me not posting very much WIP stuff. To try to combat this, I'm just going to post some stuff from the last weeks.

“You need to try harder.” “Don’t be lazy.” “Nobody likes doing that stuff.” “Just make a plan & stick to it.” “Set a reminder in your phone.” “It’s not that difficult. Grow up.” Those with #ADHD know how it feels to struggle with basic habits that seem “easy” to other people 😞
