Building a Custom Integrated Circuit Package

Whilst working on the update for the μVolume project, one of the features I wanted to test was the ability to not only receive infra-red signals from a remote control but, to also transmit emulated infra- red signals. This could be used to control such a device as a TV or surround sound amplifier. An IR transceiver package was the obvious choice! After a lot of searching I concluded that the available parts were all basically costly, tiny SMD packages intended for the transmission of data between devices within a 1 metre range, such as laptops and mobile devices.

These additional components could be included on the actual PCB, however, that would have involved a re-spin. Plus, I prefer to keep the current PCB tidy and free of floating bodge wires and components.

Wesco Pushboy Bin Astromech Trolley

Founded in 1867, Wesco have been making products for over 140 years. There is no denying their designs are iconic. After a recent purchase of a red Wesco 50 litre Pushboy bin, which is located in front of a pantry door, it became obvious that it's two part design made it awkward to move out of the way.

Whilst there is a trolley available for the PushBoy, plus other models in Wesco's range, I did not find it particularly attractive, not forgetting the additional £50.00 cost to an already very expensive bin!

I decided to design a trolley which would be (1) Practical, (2)attractive and (3) have a stable footprint. The design should take into account as you fill the 50 litre capacity the centre of gravity rises, as does the tipping point

Dellcade Compact Arcade Machine Build Part Two: Ones and Zeros

Initially, I planned to mount the Raspberry Pi up against the back plate so that the external leads would connect directly to the Pi, which would have been convenient . However, I decided to use short 300 mm extensions for HDMI, USB and Network to allow the Pi to be mounted with more flexibility inside the enclosure.

I hope I have inspired a few of the readers to unleash their favourite screwdriver whilst, their girlfriends, partners (or the other way round) or in my case wife, watches so called... 'Reality TV!'

Dellcade Compact Arcade Machine Build Part One : Design and Conquer

This wasn't my first rodeo building an arcade machine to relive the 1980's, a time when 10 pennies gave me 3 lives on my favourite game Gyruss. My first bar top style was rather heavy, clumsy and hard to transport. I aimed to rectify with a lighter and more transportable version to be enjoyed with friends reliving their youth!

With the Raspberry Pi version 2 featuring more RAM and horsepower, a true MAME
experience was at hand... time to design a more compact, lightweight bartop with a twist.

Arcade Button Modifications, Monkey likes Shiny

Illuminated arcade buttons seem to be the popular choice for machine builds of late and for good reason! For my latest arcade machine build I wanted go with a more subdued look with a black and silver grey palette.

Whilst I could have gone with black buttons, I preferred the idea of the machine seemingly coming alive when turned on. Not happy with the supplied single colour LED I decided to investigate a few modification options, one being the use of the WS2812B or Neopixel, addressable through a small micro-controller.

Tinting Epoxy Resin with Toner Powder to Maintain Strength and Stop Discolouration

Building complex projects with composite materials often involves the use of specialist glues, either for strength or athletic reasons.


Other uses for tinting or colouring epoxy resins are for the potting of electrical components or cable strain relief , the latter I will describe as the example in this guide...
