Version 2 of the desktop Othermill milling machine is now available, and it’s accurate enough for a range of machining tasks, including double-sided PCBs.
The machine can handle a range of materials, like brass, aluminum, wood, and plastic. For PCBs, FR-1 is recommended over FR-4. With a small milling bit, footprints as fine as TSSOP & TQFP can be created. Solder paste stencils can also be cut using the mill.
For a good walkthrough of PCB creation, read this blog by Tom Simon, a user who liked the Othermill so much he joined the sales team.

Typically when electrical engineers wants to make a new circuitboard, they need to send their design files to a manufacturer and wait for it to be produced and mailed back. Hardware startup Voltera aims to expedite this process by putting it in on your desk with its V-One consumer circuit board printer.

Even a simple, well-designed tool can help significantly – we´ll introduce to you some of them …
Sometimes, only a little bit is necessary to make our work more happy – a good ergonomic chair, workbench in a suitable height, good lighting … and last but not least also a good screwdriver, magnifying lens, tweezers, or „something“ what can help at extraction of a component from a PCB or at cleaning of a suspicious place with a possible shortcut.
If we´d start by the smallest one, then it could be the ZD-151 set – i.e. six various “surgery” tools serving for bending of THT components leads, extraction of components from a PCB, cleaning of a joint (brass brush) as well as interruption of unwanted connection on a PCB. Especially suitable for work with SMT components is the set of four stainless steel tweezers 816748. By the way, for a work with sensitive components it´s certainly worth to use antistatic wrist band (suitably earthed).
If you already find a place, which should be resoldered or a component should be extracted, then there will be certainly useful desoldering pumps ZD-192 or ZD-108 from an ESD plastic. For a thorough removing of all solder residues, especially at exchange of SMT components, it´s usually necessary to use a desoldering braid, for example Toolcraft – in various thicknesses (1.0-3.0mm) or a top-quality braid with a synthetic flux Soldabsorb.
Soldering tool – that should be laid off into a reliable holder – for example ZD-10 but we´re also able to supply you various original parts from Weller, Ersa and other.
At soldering and especially at a lead-free process, it often happens, that even a relatively new soldering tip gets covered by a thin oxide layer and the tip then “doesn´t catch” solder (poor wetting). If a mild cleaning on a soft-wetted sponge (ZD-937), doesn´t help, or often better – on a dry brass or stainless steel wool – AT-A900, then it might be good to use something more efficient – regenerator of tips Stannol Tippy or Weller TIP ACTIVATOR (T0051303199).
It´s known, that solder smoke and fumes are harmful and your health is surely worth much more than the ZD-153 fumes extractor.

Do you like tools usable for several jobs? Gas soldering tool Dremel VersaTip 2000 in a “Decorating kit” edition certainly belongs to such record breakers in the versatility of usage.
Multifunctional gas tool Dremel VersaTip 2000 usable for technical but also creative works was introduced to you in our articles. Soldering, melting, hot-cutting, welding and wood burning (pyrography), bending of metals, application of heat shrinkable insulations, releasing of junctions locked by an anaerobic sealant (bearings and screws) and now also various creative works can be done with a special edition „Decorating Kit (DremelVersaTip2000-6)”. This set also contains a few additions to develop creativity of a user (of families :-)), namely: embossing pen, 3 embossing powders, embossing stones and 2 wooden sheets with pre-cut shapes to try this technique.
Embossing pen contains a slow-drying glue. If we put some embossing powder on to an ornament painted by this pen, it will get sticked in a thin layer. Then it´s only necessary to heat it up by a hot air from the VersaTip tool and an attractive color layer is done. Possibilities of usage of this technique are wide – after some exercise it´s possible to use it for example to mark your own „hand made“ products giving them a mark of unique. In general, the embossing lacquer (glue) can be applied also by a suitable rubber stamp (sold in specialized shops), what can give us a relatively very quality, sharp result.

lowpowerlab.com imported a laser cutter from China and discuss the process:
As a break from the pick and place posts, in this article I’d like to aggregate my research about laser cutters and my experience importing a chinese laser cutter. There’s a wealth of knowledge scattered around the web, and this article won’t meet everyone’s search criteria, but hopefully this will be a resourceful stop for those that are in the search for a similar machine on a budget that can achieve the same results as a high end laser cutter/engraver.

Manual Pick and Place V2 @ Brian Dorey.com
After finishing the automatic pick and place project we soon found that we needed to be able to place components manually when working on prototype and very short production runs of pcb boards.
As the space in the loft workshop is very limited we decided to modify the old manual pick and place machine and make a new compact version which can be stored under the bench and put on the top when needed.
For the frame we used 40mm x 20mm aluminium extrusion and made a frame which is 40cm deep x 45cm wide.

Arduino UNO R3 mini laser cutter:
A few years ago I saw an Instructable where Groover had used a pair of DVD-RW drives to make a pocket laser engraver. Inspired by the idea, driven by the recent purchase of a full-sized 50 watt CO2 laser cutter, and roused by the launch of the Microcontroller contest I took the decision to have a crack at making my own mini laser engraver.
