London Good Delivery Bars define standards for gold and silver ingots. These are usually the ingots you see in movies. This post contains drawings I created for molds made from 1/4″ (6mm) mild steel. Below you’ll find a pdf with the dimensions. Your browser does not support embedded PDFs. Download the PDF instead. See the creation of the molds below:
For RVs and vans, generators are very useful but very loud. I wanted an enclosure that is both waterproof and noise dampening. It’s hard to find something like this, because it’s not easy to encase an engine and keep it cool. In the end, I failed to keep the generator cool enough to for more than 2 hours. I used a Wen 56235i generator. It is a cheaper variant of the Honda EU2200 series. ...

AC Delco Model 16131355 This post details the repair of a early 1991 AC Delco stereo. AC Delco made many variants of this stereo for both Chevrolet and GM cars, trucks, and vans from the early 80’s to the mid-90’s. While many of the stereos have more or less features (cassette players, radio presets, etc), the amplifier section of the radio is fairly standard and unchanged. Internal Pinout and Schematic ...
I’ve looked and been unsuccessful in finding household nightlights that meet my criteria: auto on/off dimmable 1800K CCT decent CRI uniform illumination no flickering power efficient The closest I found was this nightlight. I like everything about it except the 3000K CCT. I believe it’s a bit too cool for a nightlight. I ended up swapping the 3000K LEDs for 2200K LEDs. I would have preferred 1800K, but was unable to source them on Digikey. ...
Octopart, the search engine for electronic and industrial parts, doesn’t post the pricing for their API on their website. There’s a bit of irony, since Octopart scrapes pricing from sites like Digikey, who also tries to hide their pricing. The Octopart API is a great resource for pricing BOMs. KiCost is a great example of tool that uses the Octopart API (although KiCost has moved away from Octopart due to the paywall). As of June 2019, the Octopart API is as follows: ...
Note - There are many versions of the Motorola Razr, each with subtle differences. Even similar version have differences between countries. Not all of the differences of this counterfeit/refurbished Razr will apply to your Razr! This applies specifically to the Motorola Razr V3, but you can find similar discrepancies on a Razr V2 or V3i. If you have a feeling the phone is fake, that’s a good indicator that it is. ...
Left- Authentic Razr V3, Right - Counterfeit Razr V3 I recently bought a Razr V3 on eBay. The listing below shows that it is made by Motorola. The pictures are of an authentic Razr. However I received a counterfeit Razr. PS - I wrote a quick guide on spotting counterfeit Motorola Razr V3’s (without disassembly). If the phone would have worked, I wouldn’t have cared. But it wouldn’t get a signal with my SIM, so I complained and got a refund. ...
