Testing
Some of the many specifications and procedures used in blast and ballistics testing.

Essential Testing

It essential that products designed to protect people and property undergo thorough testing. The staff at SJH Projects have carried out many explosive trials in the process of product development. We can help you exploit this experience to bring your own products to market.

The process starts with a consultation in which the end use and market sector requirements are discussed. Advice is then given on what level of testing, and where necessary, what formal test specifications should be followed. Liaison with the test ranges is then undertaken and all the planning other than test item manufacture is carried out on behalf of the customer. If required, the test footage/photos and data can be edited into a short movie or clips for presentations to potential customers.

Blast Testing

We have carried out a wide variety of blast test using the appropriate specifications for the industry or application at hand. SJH projects can also assist in designing your test configuration and the test rigs themselves. Test management, data and imagery processing and detailed reporting can be provided to fully support the customer’s needs.

Ballistic Testing

SJH Projects can also arrange ballistic tests and assess product durability appropriate to the intended use. 

While most of the world blamed a simple "chip shortage," the reality was far more complex. The global semiconductor supply chain—a $600 billion labyrinth involving raw wafers, specialized substrates, and third-party logistics—had broken not because of a lack of demand, but because of a catastrophic lack of visibility .

Enter (YC Winter 2019). After five years of quiet infrastructure building and a brutal stress-test during the supply chain crisis, the company is launching its new platform. And it is turning the old model of procurement entirely on its head. The Y Combinator Origin: 2019 vs. 2025 When FirstChip graduated from Y Combinator in 2019, the pitch was simple: “We are the Bloomberg Terminal for semiconductor sourcing.” The original product was a price comparison engine for spot-buying microcontrollers and memory chips. It was useful for procurement managers, but it was reactive.

If successful, FirstChip will have achieved what the EU Chips Act and the U.S. Department of Commerce have failed to do: bring true visibility to the most opaque supply chain on earth. The phrase "firstchip+yc2019+new" is more than an SEO keyword. It marks the evolution of a startup that survived the apocalypse of global trade. It tells the story of a Y Combinator winter cohort company that has matured into a critical infrastructure player.

Using search filters, the procurement agent did not look for the chip. Instead, they looked for a "manufacturing anomaly." The AI flagged a consumer electronics firm in Vietnam that had just canceled a production run due to a smartphone demand slump. That firm had the RH850s already packaged in trays, waiting for a different customer.

In the chaotic spring of 2020, as automotive plants sat idle and consumer electronics faced a six-month backlog, a quiet realization swept through the C-suites of Fortune 500 manufacturers: No one actually knew where their chips were.

For anyone sourcing components in 2025, the old question was “Do you have stock?” The new question, powered by FirstChip, is “Can you prove you’ll need it before I do?”

The FirstChip, unveiled in late 2024 and fully operational in 2025, is no longer a tool. It is an autonomous agent.
