It is always hard to find a gift, unique and surprising! On geeks.com I found this, the USB powered greenhouse! Not that this is of any practical use, who keeps his PC running 24×7 to grow plants? Ah, I hear the dutch think: grow cannabis (for your own personal usage … 🙂 ) at the office! So ask one for Sinterklaas. A real geek will of course order a USB powered Plasma ball! So boys, this is what I want for my birthday…. But please, not a USB powered aquarium! Filled with real water and plastic fishes. Continue reading Looking for a Xmas gift?
There are several Apple 1 clones made! The Replica-1 by Vince Briel is the first to apply modern components to replace the hard to get and therefore expensive components, like the Signetics 2513 and such, with modern microprocessors emulating the terminal part. I found another one, with a dutch background, manufactured and sold by Achatz Electronics, the A-One. The design of this clone is similar: the terminal part is replaced by (this time two) microcontrollers, for video and serial interface. Some differences between the two designs: The A-one is even more compact, less IC’s Has a real Apple 1 slot instead of … Continue reading A-One, another Apple 1 clone
A full TCP/IP implementation on a cheap IC? Yes, it is available. The Korean company WIZnet produces an IC with the name W5100 that implements a full TCP/IP stack, easy to interface to a microcontroller as a peripheral or via SPI. Perfect for controllers from AVR for example. And the interface is also suitable for our beloved old microprocessors like the Z80 and the 6502. WIZ810MJ is a simple module, a PCB with the W5100 IC and a RJ45, you get microcontroller and SPI Interface, Auto MDIX/MDIX network status indicator LEDs – FDX, TX, RX, LINK, Collision , and TCP, UDP, IP, ARP, ICMP, IGMP, … Continue reading Cheap TCP/IP Ethernet on one IC: W5100
Just back from a visit of several days in Munich, SAP Teched. All about SOA (Enterprise SOA as SAP calls their way of doing it). Now I have been to many Microsoft Techeds and Gartner symposia , and that is always a fun experience. I did not expect that much fun of solid, serious, boring SAP AG, but I am pleasantly surprised. Of course they do copy the Microsoft Teched experience, including the party at the last night (Microsoft did stop with that btw) and a keynote thats should bring about enthusiasm and cheering devoted followers Well, of course it is SAP, a German company with serious … Continue reading SAP Teched, Munich
All of us older computer geeks know that before selling Macs, Apple founders Steve Wozniak (the genius) and Steve Jobs (the greedy business man) had a lot of success with the Apple ][ or Apple 2 or whatever marketing tricks were done with the name of that remarkable personal computer. The 2 in the name suggest there was a Apple 1 and yes, there were a very limited numbers of boards sold (200 or so, 50 or o survived time, so its a valuable collectible) branded Apple 1 in the 1976-77 time-frame. It has video on board and accepts input … Continue reading Apple 1 Replica
