TDP, Thermal Design Power Very recently, the enthusiast community has dug into Intel's TDP ratings and performance. Even since Multicore Enhancement, aka MCE, the performance of Intel's CPUs has varied depending on the motherboard manufacturer. The frequency...
As the primary market of this device is for the open source community the components should be easily obtained and structures easily manufactured. ComponentsTherefore all components should be sourced from reliable suppliers with tested supply chains,...
The firmware files I retrieved all have a very simple layout. There's a head of 176 bytes or so which indicates the version, which firmware 'files' (flash partitions) are in the package, their length and their SHA1SUMs. Nothing too troublesome there....
3D Scanning Objects with a Smartphone +123D Catch Transmogrify: transform, especially in a surprising or magical manner. The future of everything is 3D and you need to get on that right now. The first step is to download 123D catch from the app store...
I think I'm done screwing around with analog goofiness for a while (hopefully). I've retested all of the monadic gates that require diodes. I've experimented with various resistor values and tried germanium diodes, silicon small signal switching diodes...
Two posts ago our CPU was demonstrated connected to an Arduino to provided memory-mapped I/O. This MMIO space could hold code, other board-level I/O functions or perform functions on the host PC. The 'memory' area of this MMIO space was slow - each access...
The shafts have been completed and added to the prototype completing the mechanical portion of the rotor hub.The method for interfacing the servo to the shaft is a little more concrete now.A lever was added to the shaft that will be used to rotate the...
Came across an article: New research project by MIT and Binghamton could make FDM 3D printing a whole lot fasterYes, it tells everyone what they already knew. The upper limit of speed with FFF with existing designs is being approached.Let me pull something...
The display tube has 100 anodes (in the default mounting orientation going horizontally from left to right) and a 100 cathodes (going vertically from top to bottom). Whenever the voltage between an anode-cathode pair goes above 235V the pixel on their...
The CPU board hosts: the CPU (1)the RAM (2)the (EEP)ROM (3)the PLD (4)jumpers to configure memory mapping (5) In this board prototype I forgot to add a jumper in order to manually select the ROM banking (RAM14). I will add another jumper...
When designing a SBC you always have to balance features vs board space vs price. When I realized I had to make a choice between putting in the time and finding a new solution to a problem many smart people have already worked hard at or throwing...
As I've recently discovered and written about in this log, Desktop Metal seems to use a fibre tape to reinforce their parts. It's likely not as economical and wouldn't be as versatile as Markforge's offering, but I'd rather take "rough but within reach"...
There is a famous song: /* 99 bottles of beer on the wall, 99 bottles of beer. Take one down and pass it around, 98 bottles of beer on the wall. ... 1 bottle of beer on the wall, 1 bottle of beer. Take one down and pass it around, no more bottles of...
