As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...
As we dismantled out old battery rack we discovered that water flooded around a centimeter under the pallet. Its a (very) old basement and we discovered that during winter water infiltrate it and let the floor wet. This is a problem since the wood rot...
(see updates at the bottom)_____________________________________________I seem to have solved the problem of cascading the latest flipflops, using better decoupling (and some diodes ?). Here's the new circuit : For the "fast" parts, a pull-down...
So I've recently got a fully electrically and mechanically complete CAD model of Tetrinsic and was, once again, doing some research for Tetent, mainly because I don't like how this featureless flat face looks: It turns out that the eteeController...
My friend Dylan Brophy inspired me to investigate the ability to output the cyrillic text using different output devices, supported by Terminal-BASIC. 1. Using symbols others then capital latin in identifiers not possible and unnecessary. 2. USART output....
When considering the keyboard layout, one has to think about what keycaps are available on the market. Those low-profile switches use non-standard keycaps, so I'm a bit limited. A quick search of Aliexpress reveled that I have a huge choice of 1u caps,...
When testing some of the firmware on the Trinket Pro side I noticed that my button IO was a bit slow. I was using a 0.1uF cap (cap code 104). This gave me (according to the MC14490P datasheet) a debounce rate of ~15Hz (at 5V). If I use a 0.001uF cap...
Update September 5, 2017 - IO is adding correctly once again. Could not isolate the problem so just started adding 104 caps to parts of the registers that had not already been filtered. Still have a very slight glitch with one led on the accumulator...
In this log I will discuss some algorithm ideas I have in mind for MARB. Some are easy, some require higher math. 1. Weather forecast MARB will not be connected to the internet. Call me old-fashioned, but it has nothing to do with AI to get for instance...
In a nutshell: For the Amstrad / Schneider CPC range of 8bit home computers Made possible by sponsoring and initiative from the one and only, legendary Future Man - TFM! https://futureos.cpc-live.com/Exclusive Limited Edition - by invitation only RSX...
Remember the last logs : the goal is to use as few transistors as possible to send a string of consecutive non-overlapping pulses to several pass-gates. Here the design uses NPN as primary type but it will be reversed later because PNP are the majority...
These are parts of AIME's operating system that I am beginning to shoe-horn into a Raspberry Pi or more probably a few Zero's networked together inside a smaller and less sophisticated quadruped. AIME was 3.2GHz dual-core intel powered and a lot more...
I've been upgrading the case and PCB design into a new form factor, one that looks much more like a gun. Compared to the first prototypes, this has a number of advantages: Easier to aimEasier to see the OLED screen while aimingHas indicator LED's to...
Bill S12:25 PM@primetimber Ture, Then when everything goes to hell, the board gets a new CEO who says that last guy was the worst and continues to do nothing. Think VW Chris Ryding12:25 PMWhere do you tend to see more security vulnerabilities - insecure...
Design to winSo online competitions there's a game to be played. A lot of the time a pretty mock up or design can do better than a more basic working model. Unfortunately when you try to make that pretty design in the real world the reality of manufacture...
