Making a Custom Planishing Dolly

Completed Planishing Dolly

I needed a dolly with the correct profile to planish out the dents in a crumpled 1930s Ariel motorcycle front mudguard. As there is no such thing obtainable, I made my own.

I had one point on this old moonscape guard with a reasonably intact original profile. Using a piece of […]

Restoring a Vintage Valanced Mudguard – Part Two

Right rear patch tacked

It quickly became clear that it would not be possible to smooth out all the dents until the metal had an approximately consistent thickness. Some of the previous repairs consisted of overlay patches and lumpy welding. On the other hand, making accurate patches for a lumpy and distorted part was […]

Splitting Jumper Wires for Arduino

A while ago I stocked up on jumper wires from Sparkfun and recently found while connecting an Arduino clone to a Raspberry Pi that the single straight header on both ends was not what was needed. Unlike the male breakaway headers, these female JST RE wire headers do not split up.

To solve this you […]

Restoring a Vintage Valanced Mudguard – Part One

Ariel Valanced Mudguard – as found

Many years ago I traded some Ariel parts I didn’t need for some Ariel parts that I did need for my Ariel VB sidecar project. This project has been progressing intermittently since 1989. One of the parts I received was a valanced front mudguard (“fender” for our colonial […]

Raspberry Pi Arduino IDE via GPIO

Raspberry Pi GPIO to Arduino UNO without USB

We want to control and program our Seeed Robot directly from a Raspberry Pi. The Seeed Hercules controller, which has an embedded Arduino compatible controller, does not have a built-in USB port. Therefore we want to bypass USB and talk serial TTL directly between the pins. […]
