Elektor Labs USB-RS232 Converter (FT231X BoB)
In 2011 we published a small PCB, FT232R USB/Serial Bridge/BOB (110553) with a USB-UART IC from FTDI, the FT232RQ. Here we present its successor with a cheaper version, an FT231XQ. But there are some other changes too. Instead of connectors, alongside the PCB, normal pin headers are used that are mounted on the bottom side and make the PCB a little smaller when mounted, compared to the old BoB. An ESD protection device (D1) is added in the USB data signal lines for extra safety. Despite less room for all parts to fit on the PCB, it is only a little over 2 mm longer. The FT231 has four configurable CBUS I/O pins, one less now. More importantly, however, the power supply for the I/O's VCCIO is only specified for +1.8 V to +3.3 but is 5 V tolerant for external UART logic running on +5 V. The +3.3 V internal regulator of the FT231 can deliver 50 mA to external circuitry. The manufacturer FTDI has a utility to configure several settings, FTPROG. Such as the function of the CBUS pins. By default, CBUS1 and CBUS 2 are low-level outputs to drive receive and transmit LEDs, indicating data transfer on the USB bus. So, when receiving data through the UART, the TX LED lights up. If you prefer this the other way around, FTPROG can be used to change this. But be careful the chip can become unresponsive when wrong settings are programmed. Some of the more important properties of the new BoB: Micro-USB connector USB 2.0 Full Speed capable VCCIO +1.8...+3.3 V (max. 4 V, 5 V input from UART logic tolerant) +3.3 V regulator output, max. 50 mA Data transfer 300 baud to 3 Mbaud UART Compatible with RS232, RS485, and RS422 I/O pin output drive 4 mA - 16 mA 4 configurable CBUS pins Here you can find information regarding the EEPROM Programming Utility, the VCP Drivers and the D2XX Drivers.

Evil Mad Science AxiDraw SE/A3 Writing and Drawing Machine
The AxiDraw SE/A3 has the same extended plotting area as the AxiDraw V3/A3. In place of the central extrusion that makes up the body of that machine, the AxiDraw SE/A3 has a central beam that is CNC machined from a solid billet of 6061-T6 aluminum, and then anodized to a sleek black finish.This heavy, rigid structure – it's a solid block of metal! – provides dramatically better straightness and stiffness, even compared to the already-stiff AxiDraw V3/A3. This design adds mass exactly where you want it: to the non-moving base that forms the X-axis of the machine. In order to keep the weight light where it matters, the moving Y-axis of the AxiDraw SE/A3 uses the same stiff and light custom aluminum extrusion that we use on the AxiDraw V3/A3.Beyond this, the central beam and X-axis of the AxiDraw SE/A3 feature an all-new geometry for the rolling wheels, which provides more stable and uniform motion along the axis.Getting StartedThe AxiDraw comes fully assembled, tested, and ready to use, right out of the box. A universal-input plug-in power supply is included with the AxiDraw, as is a USB cable, and an optional paper-holding easel. Assuming that you've installed the software first, you can be up and plotting within minutes of opening the box. Our comprehensive PDF user guide walks you through every step of the process.To operate AxiDraw, you will need a reasonably modern computer with an available USB port (Mac, Windows or Linux), plus internet access to download necessary software. Pens and paper are not included. (You can use your own; AxiDraw does not require proprietary pens or paper.)AxiDraw is normally controlled through a set of extensions to Inkscape, the excellent, popular and free vector graphics program. Basic operation is much like that of a printer driver: you import or make a drawing in Inkscape, and use the extensions to plot your text or artwork. It's all handled through a straightforward graphical user interface, and works cleanly on Mac, Windows and Linux.SpecificationsPerformance Usable pen travel (inches): 16.93 × 11.69 inches Usable pen travel (millimeters): 430 × 297 mm Vertical pen travel: 0.7 inch (17 mm) Maximum XY travel speed: 15 inches (38 cm) per second Native XY resolution: 2032 steps per inch (80 steps per mm) Reproducibility (XY): Typically better than 0.005 inches (0.1 mm) at low speeds.

Evil Mad Science AxiDraw V3/A3 Writing and Drawing Machine
As compared to the (US Letter/A4 sized) AxiDraw V3, the AxiDraw V3/A3 has extended travel range, designed for use with paper sizes up to and including 11 × 17 inch ('tabloid' or 'ledger') and A3. It can work with any paper up to and including that size, including envelopes, regular US letter (8 1/2 × 11 inch) or A4 (297 × 210 mm) sized paper, note cards, business cards, or a whole array of smaller items. The AxiDraw comes with a mounting easel (board with clips) that can be used for holding paper, cards, and envelopes of various sizes. The AxiDraw V3/A3 also comes standard with AxiDraw Outrigger Feet pre-installed, for greater stance and stability while plotting. The unique design of the AxiDraw features a drawing head that extends beyond the body of the machine, making it possible to also draw on flat objects bigger than the machine itself. For example, you can set it right on top of a box to write an address or add decorations. You can even set it on top of a poster board, chalkboard, or whiteboard to draw graphics in place. The pen holder fits a wide variety of pens, including Sharpie fine and ultra-fine point markers, most rollerball and fountain pens, small-bodied whiteboard markers, and so forth. It can even hold a fountain pen at a proper angle of 45° to the paper. You can also use implements that aren't pens, such as pencils, chalk, charcoal, brushes, and many others. However, you'll get the best results with instruments such as fountain pens and rollerball pens, which do not require the user to apply pressure.

Robins Tools Pixel Pump – Pick-and-Place machine voor handmatige SMD-assemblage
Pixel Pump is een open source vacuümpomp voor handmatige SMD-assemblage. Hij wordt geleverd met een comfortabele pen, een voetpedaal, RGB LED-knoppen en een aantal functies die handmatige assemblage veel leuker maken. Het is de perfecte metgezel voor het handmatig SMD-solderen, van individuele prototypes tot kleine productieruns. Doordacht ontwerp van hoge kwaliteit Pixel Pump wordt geleverd met een set van vijf roestvrijstalen mondstukken in vijf verschillende maten, met buitendiameters van 0,3 mm tot 1,8 mm. Met deze set zou je de meeste SMD-componenten moeten kunnen plaatsen, inclusief kleine 0402-componenten, grotere onderdelen zoals spoelen en IC's, en zowat alles daartussenin. De mondstukken worden op hun plaats gehouden door een Luer lock slip fitting die snel wisselen van deze mogelijk maakt en brede compatibiliteit met mondstukken van andere fabrikanten. De pen zelf heeft een snelkoppeling voor de luchtslang en vier M8 stalen moeren om hem wat stevigheid te geven en magnetische bevestiging aan de Pixel Pump mogelijk te maken. Tactiele siliconen knoppen met RGB-achtergrondverlichting bieden volledige controle over het apparaat. Je kunt de werkingsmodi wijzigen, schakelen tussen hoge en lage energie-instellingen of de omgekeerde modus activeren om de zuigmond te reinigen. Met de knoppen kun je ook dingen configureren zoals zuigkracht en LED-helderheid. Pixel Pump heeft een drukontlastingsventiel dat vacuüm dumpt om ervoor te zorgen dat je onderdeel snel wordt vrijgegeven wanneer je het voetpedaal loslaat. Optioneel kun je dat ventiel zo instellen dat het overschakelt van de zuigmodus naar de drukmodus, waardoor het mondstuk snel en eenvoudig wordt gereinigd als je per ongeluk vuil hebt opgezogen, zoals soldeerpasta. Een gesinterd luchtfilter beschermt de vacuümpomp en kleppen tegen vuil dat anders in het systeem zou kunnen worden gezogen. Het is van buitenaf toegankelijk en kan eenvoudig worden gereinigd en hergebruikt. Een perfecte metgezel voor prototypeboards en kleinschalige productie Pixel Pump is voornamelijk ontworpen voor mensen en organisaties die eenmalige prototypes maken, maar het is ook zeer geschikt voor kleine productieseries. Het is zeer eenvoudig te gebruiken en is eigenlijk sneller dan een geautomatiseerde pick-and-place machine voor kleinere batchgroottes, vooral in combinatie met SMD-Magazijnen. Pixel Pump is de perfecte metgezel voor hobbyisten en professionals die graag hun eigen printplaten maken. Kenmerken Comfortabele pen waarin verschillende mondstukken passen Kleine, flexibele, hittebestendige siliconenslang die de pen met de Pixel Pump verbindt Magnetische basis voor de pen Sterk, regelbaar vacuüm, perfect voor het oppakken van zowel kleine als grote onderdelen Tactiele, siliconen RGB-knoppeninterface Voetpedaal voor het activeren van de pomp Instelbaar hoog/laag vermogen Instelbare LED-helderheid Omgekeerde modus, die druk creëert in plaats van zuigkracht om mondstukken te reinigen Vacuümontlastklep voor snelle drukverlaging om onderdelen sneller te laten vallen Eenvoudige software-updates via USB-C Compact ontwerp dat het beperkte oppervlak van je werkbank respecteert Downloads 3D STL Files Firmware Mainboard Schematics UI Board Schematics Motor Controller Schematics
